Started car to reverse out of parking space and it started jerking as I accelerated. Drove jerkily the few blocks I had to go to make it home. Did not drive again but upon starting it the check engine light came on. Contacted Hyundai customer care who told me my car was covered under two extended warranties for a well documented engine failure on this exact vehicle - Hyundai Santa Fe Sport 2017. I’ve been researching and Hyundai knows about this problem and it had been through the courts after group legal action was taken. Hyundai refuses to pay for the car they know is a failure to be diagnosed. I cannot afford to have the car diagnosed especially not for a problem that Hyundai and half the world know (and have documented) is Hyundai’s fault. Vehicle can not be driven.

After we had the Hyundai 9C2 recall completed a few weeks ago, we immediately had rough shifting in our Hyundai Santa Fe Sport driving off the lot. Problem has continued since, and is most notable after cold start/once the car has sat for an extended period of time. Hyundai has released a Drivability Information on 5/18/26 regarding the known issue, but our Dealership was unaware. The Dealership recommended replacement of the Transmission, despite my explanation that the issue began after the installation of the recall fix.

This is in reference to the Hyundai 9C2 ECU software update for Theta II engines that have caused my 2017 Santa Fe Sport to hesitate, surge and run poorly the first few minutes after a cold start! I contacted my dealership but they have not offered any resolution as of yet even though Hyundai Corporate is well aware of the problems caused by the 9C2 software upgrade!

I was driving my car and it showed no signs of any issue but the engine light came on and started blinking so I pulled over and got it towed to a mechanic. He told me that I would need a new engine that would cost me $8000. I looked into it and found that there was a defect with my vehicles engine and that if I took it to a dealership, I could possibly get it covered 100% so I did that and then they covered it and when I got the vehicle back, it had an issue every time I drove it where it was kind of speeding up and jerking when I drove it, I took it back after I told them what happened and then they told me that my catalytic converter was bad and needed to be replaced. I ended up paying $1500 to get that replaced and when I got the car back again it’s still jerking and doing the same exact thing even worse. I contacted them. They told me to bring it back which I did and they told me that it needed a software update that was not available so that I would just have to be patient. They told me that anytime I wanted to drive it I had to let it warm up for 5 to 10 minutes and that it wouldn’t do that. I’ve had my vehicle back for over two weeks and it doesn’t matter if I warm it up or not it’s still doing the same thing. I do not feel safe driving this vehicle and I have not been giving any resolution by either the dealership or by the consumer affairs case manager that I have been working with on this. This has been an ongoing issue for three months now. It’s costed me hundreds

Harsh engagement or hesitation between gears 1 through 3 specifically during cold starts before the powertrain warms up. But also during driving in the highway.

Service Campaigh 9C2 Following completion of Service Campaign 9C2 (Theta II Emissions Improvement), certain vehicles may exhibit a brief hesitation or rough shifting condition during cold start operation. My 2017 Hyundai Santa Fe sport has severe loss of power and rough jerky transmission after the update. This condition will definately cause unsafe driving and vehicle engine and transmission damage. Hyundai corporate and local dealerships indicate no remedy for this situation. Dealer also indicated that Hyundai corporate may not release a new software update to fix the issue. This is unacceptable.

Campaign /Service Update 9C2 / TSB-25-01-087H broke my Hyundai. The car hesitates idling and on acceleration. Hyundai have no solution to this failed software update or acknowledging other issues it may be causing.

My 2017 Hyundai Santa Fe was brought to a local Hyundai dealership for routine maintenance on July 1, 2026. The 9C2 software update was installed, without my knowledge or consent, during this service. Immediately after getting my car back, I noticed a problem starting the car (though no warning lights or alerts populated). The car seems to stall and then jerk during the first few minutes of driving, particularly after a cold start (car has been sitting for a few hours before starting). This has been a KNOWN issue by Hyundai for several months, yet this update continues to be installed. There is currently no fix, and Hyundai simply suggests letting the car "warm up" for 3-5 minutes before ever driving it. I have reported this to Hyundai corporate and have no other resolutions or timeline on a fix. Many other individuals are affected. This is particularly dangerous due to drivers not always having the ability to wait 3-5 minutes to let their car warm up, and the car is quite difficult to control with all the initial jerking and stalling. I live in a residential neighborhood and continue to be nervous about lack of control over the car when leaving my home. I firmly believe Hyundai should be held responsible for fixing this issue urgently.

I took my SUV to get the 9C2 recall on 8/7/2026 performed and took it home. The next morning when I cranked it and left my driveway it acted as if the vehicle didn't recognize that I was pressing my accelerator. It sputtered and hesitated acceleration for about five minutes. It also acted as if it was not going to change from first to second gear. After about five min. of playing with the gas pedal it straightened out. Twice I was almost hit by other cars expecting me to pull away from a stop sign. I took it back the next day telling the service agent what was happening and he kept it overnight. I received a text saying the technician was unable to find a cold start problem and it was ready to pick up. I was so mad I could barely hold my temper. I took it home and for the next week every single day it acted like this when cold started in the morning. I took it back to Premiere Hyundai of Harvey and was treated rudely this time. They acted as if they never had a single other complaint and told me I might have to leave it for several days so they could cold start test it for several days. This was on a Wednesday morning 8/19. I was never updated or called and when I texted my service rep on Monday 8/24 I was told the tech was not able to duplicate the complaint and to come pick it up. I will not ever buy another Hyundai because of the way I was treated and lied to. PLEASE create a recall for this badly handled recall 9C2. My Sante Fe Sport ran beautifully before this recall mes

My 2017 Hyundai Santa Fe Sport exhibits a documented mechanical failure under active code P0420 (Catalytic Converter Efficiency Below Threshold). This failure is the direct proximate consequence of a severe, long term manufacturing defect in the Theta II engine block, which has caused excessive oil consumption. Following the official 1,000 - mile diagnostic driving protocol completed on XXX, Keffer Hyundai (a Hyundai dealer located in [XXX]) service department officially confirmed the active code P0420 catalytic converter failure. They issued a formal written recommendation to replace the entire engine assembly but generated an out-of-pocket consumer estimate of $10,035. This case falls under the the terms of the Theta II Class Action Settlement which requires Hyundai to cover the defective engine block under the Lifetime Warranty Extension, along with any subsequent component damage (the Catalytic Converter) destroyed as a direct result of the engine's oil burning defect under the Lifetime Warranty Extension. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Brought my 2017 Hyundai Santa Fe Sport into the dealer on July 25, 2026 for the ECU and Theta II software update (Hyundai Service Campaign 9C2). Before the recall service my car drove perfectly with no issues. After the recall service my car is extremely jerky when shifting at low speeds and has long delays when trying to accelerate. This problem is particularly apparent on cold start, and less so once the vehicle has been driving. The issue is not as noticeable if the vehicle has been driven, is turned off, and then turned on again before fully cooled down. The jerky shifting has been getting worse over the past month. Vehicle was taken back to the dealer that conducted the software update on August 26, 2026 and they charged me for throttle body cleaning and EFI service which they performed for carbon build up as they cited this as the cause for the issues. The issue was not resolved from this service despite the dealers claims and the vehicle still has the same jerky shifting and delayed acceleration on cold start. There are no warning messages. Issue is becoming more widely documented among users after this particular service campaign so it is not an individual isolated problem.

In June 2026 I took my vehicle to Hyundai for a recall to the ECM module. After that my vehicle would lose power and hesitate to shift gears, and overall does not feel safe. Took vehicle back to dealer and they have told me that I have to wait for them to issue a recall fix for this now .

On February 24, 2026, I had the 9C2 software update. My vehicle was being checked for oil consumption. Since then I have had issues with it hard shifting when first starting to drive and sometimes after I've been driving a while. This has continued miles down the road, sometimes over thirty minutes after driving. It also just feels continuously like it is not driving smooth. This only started after the update. I contacted HMA. The first person on my case (Gurvinder) told me I needed to return my car, not to drive it. I had bronchitis, so I did not immediately do that. The next person "Rainey" told me it is a KNOWN issue and they are telling people to warm their cars up for around 3 minutes, and it will be fine. I'd done that, and even driven longer than that. I told him that. I took my mother-in-law home from church miles from there after collecting her at the church door, etc... Getting to the hill at to her home, I didn't think it was going to get up it. Often I don't think I'm going to get out of my driveway, a dangerous driveway in a curve. He wanted Krause Hyundai to contact HMA Engineer. When I was at Krause, they didn't know how to get ahold of HMA Engineer. Dalton also said they can't back the update out. I'm on my third HMA Case Manager. She keeps changing what I've told her is wrong in the emails, I don't think she knows anything about cars. She won't listen when I say I spoke to Dalton at Krause; she keeps speaking to John. [XXX] said they can do diagnostic, but it

Airbag light illuminates on the dash and the seatbelt light illuminates intermittently as the seat electrical harness under the seat only connects in certain positions of the seat. My issue is associated with the passenger seat. This airbag light is associated with the airbag not firing or improperly firing. To avoid a recall, Hyundai has extended the warranty for vehicles for this issue but refuses to fix mine without payment.

After the recent "important service campaign" involving the THETA II Emissions Logic Improvement my vehicle no longer safety shifts into the lower gears. It will not shift into gear. I am unable to safely get up to a normal speed and the engine and vehicle start shaking. This is isolated to the initial start of the vehicle and any low speed driving after. The issue is resolved after restarting the car, suggesting it is a software issue. This issue immediately began after the ECU update for the THETA II emissions logic improvement on 5/12/2026.

Odometer Fraud. The contact purchased a 2017 Hyundai Santa Fe Sport. The vehicle was a dealer sale. The contact stated that while attempting to trade the vehicle, the contact was informed by the dealer that the odometer had been rolled back prior to the purchase. The contact had purchased the vehicle in March 2022. A Carfax report indicated that the odometer was reported at approximately 75,585 miles on January 28th, 2022, and 55,710 miles on February 11, 2022, reflecting a 20,000 miles difference. The contact stated that the mileage at the time of purchase was unknown. The vehicle currently had approximately 132,064 miles. The issue was reported to the Pennsylvania State Police and the Pennsylvania Attorney General.

After a recall repair (Campaign 9C2) was performed on my vehicle, it developed a hesitation and lack of acceleration issue that did not exist before the repair. The vehicle exhibits rough or delayed gear shifting, a noticeable lack of power/acceleration, and behavior that feels like the engine is not receiving adequate fuel. This occurs both during cold start and after the vehicle has been driven and is fully warm

We have a 2017 Hyundai Santa Fe Sport with a refurbished engine due to a past class act settlement, we were notified by Hyundai to bring in the vehicle for Service campaign 9C2 to update the Engine Control Module (ECM) Software for vehicles equipped with the (2.4 GDI) Theta II refurbished engine, which we have. The morning after we updated the 9C2 software, after starting our car cold for the first time in the am, our car went into limp mode, shaking very badly, it would not accelerate above 20 MPH, it had a lot of trouble shifting from 1st to 3rd gear and acted like it was going to stall out and then die in the middle of the road while I was in the car with my 2 children. The dealership we took it to was not able to duplicate the limp mode, but has documented that they did witness hesitation and sluggishness while test driving it. I cannot validate that it was test driven cold immediately as requested as all their test drives were done without me. Due to the vehicle not accelerating as it should normally, I feel the vehicle is very unsafe and unreliable as well. I’m willing to provide more documentation, and our car is available for further inspection. I did request the help of a Hyundai customer relations case manager who stated Hyundai is aware of all of the drive-ability issues I have stated and he said they are hoping to provide another software update, but that time frame is unknown. Dealership mechanic stated the same thing and believes our issue is related to the 9C2

After a recall repair (Campaign 9C2) was performed on my vehicle, it developed a hesitation and lack of acceleration issue that did not exist before the repair. The vehicle exhibits rough or delayed gear shifting, a noticeable lack of power/acceleration, and behavior that feels like the engine is not receiving adequate fuel. This occurs both during cold start and after the vehicle has been driven and is fully warm. I returned the vehicle to the dealership (Wallace Hyundai), where the service advisor personally test drove the car with me and confirmed he could feel the hesitation firsthand. Despite this, the dealership stated no issue was found and advised warming the car up for 1-3 minutes before driving as a workaround. I tested this exact recommendation, and the issue returned even after the vehicle was fully warmed and had already been driven. Hyundai Motor America's National Consumer Affairs department has stated this is "under review" but has also described the hesitation as "normal" cold-start behavior related to catalyst warm-up. This does not match what I am experiencing, since the issue also occurs when the vehicle is already warm, and their own dealership's advisor confirmed the problem exists. I have also noticed a decrease in fuel efficiency (MPG) since the software update associated with this recall. This issue directly affects the safe operation of the vehicle — specifically the ability to accelerate reliably, including in situations like merging onto highways o

Campaign 9C2 was installed on this vehicle and the now the vehicle is a danger to drive. My wife refuses to drive it as it bucks and jerks as well as the gas mileage has decreased from 35 highway to 28 highway. The fuel trims are way off on cold starts and the transmission now searches for the correct gear. Shifting back and forth. Just a slight touch of the accelerator and the car seems to jump forward which makes stop and go driving almost impossible.

Steering column sensor issue reported by Hyundai dealership. This has happened a several times before causing the steering wheel to “lock up” when driving making it very hard to turn my wheel. I have had to pull over, stop, and turn off the car and then back on again, which resets it, and I’m able to drive as normal, until it happens again. This most recent time, 6/2026, I was able to take it in to a dealership when the warning lights were on. He did a recalibration, however, later when driving, the same issue arose at high speeds, on the fwy, causing me to exit and pull over. * I noted 2- 3 warning lights came on during the malfunction.

What component or system failed or malfunctioned, and is it available for inspection upon request? Multiple systems have failed sequentially — engine (replaced at ~84,000 miles), catalytic converter (replaced post engine replacement), and transmission (currently stalling, pending replacement authorization from Hyundai Corporate). The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? The vehicle stalls during the first few miles of every drive before stabilizing. This creates an immediate risk of accident on public roads, particularly at intersections, highway on-ramps, and in traffic. Despite this known safety hazard, the dealership returned the vehicle to me unrepaired on June 22, 2026, and deemed it safe to drive. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Fort Mill Hyundai (805 Gold Hill Road, Fort Mill, SC 29708) has confirmed they can physically feel the stalling issue but stated they do not have sufficient data to submit to Hyundai Corporate for transmission replacement authorization. An independent mechanic also previously confirmed the engine issue that the dealership initially dismissed. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. Fort Mill Hyundai, an authorized Hyundai dealership, has inspected the vehicle multiple times over several years. The dealership is actively coordinating with Hyund

My 2017 Hyundai Santa Fe sport has never had any issues until last Friday when I took my car to the dealership for regular maintenance (oil change, tire rotation) as I always do. They also performed a software update for recall campaign 9C2. Every day since, when first starting the car after it’s been resting for a while, I’ve experienced a jerky transmission and rough shifting for a first couple minutes of driving. Hyundai has acknowledged they are aware of this issue related to the campaign and the dealership said they’ve had many customers complaining of the same problem following the recall update. However, Hyundai has offered no resolution, other than recommending the car warm up for 13 minutes after starting. Hyundai needs to correct the issue they caused, as my car was perfectly fine before it was serviced and now it’s not performing properly.

Following the completion of an official emissions recall software upgrade at Fitzgerald Auto Mall Countryside, Clearwater Florida, my 2017 Hyundai Santa Fe Sport (52,000 miles) now suffers from a severe loss of motive power and erratic transmission shifting/jerking during cold starts throughout day. The vehicle continues to hesitate during cold starts, making it impossible to safely accelerate from a stop into incoming traffic. I returned to dealership on 5/29/26 to address continued driving issues. The servicing dealership states they don't have a software fix and offer no mechanical fix. The dealership states they received an internal memo from Hyundai Corporate which instructed the dealership to tell affected owners to idle the vehicle for 1-3 minutes before driving to allow system adjustments. Forcing a consumer to wait out a dangerous powertrain defect in a running vehicle to avoid a roadway acceleration/loss accident is an unacceptable safety hazard. The manufacturers recall update has actively compromised the safe operation and motive control of this vehicle.

After the ECM recall for a software update the car would not run correctly. It jerks and and runs rough. It almost stalls when you put your foot on the gas. I took it back to the dealer and they can not get the problem to duplicate. Noone else has looked at the problem. There were never any problems with the care until the recall. The problem occurred the day I brought the car home from the ECM update.

Hello, I was driving home from work with my six-month old in the car and the engine stalled while on the Belleville Turnpike. It seized and I was almost rear-ended by a tractor trailer hauling lumber to the lumber yard just a few streets away. I couldn't move the car and was afraid of how to even attempt to secure my car as my daughter was strapped in her car seat. An extremely nice man pulled over and began to flag vehicle to go around me. By this time, I had only my hazard lights on. I was frightened beyond belief having gone through that experience. The car was towed to the dealership who confirmed it was catastrophic engine failure(misfire of a cylinder). They stated initially with my 3rd party warrant that it would be covered and in their words " it was a good thing I had a warranty". Fast forward to two weeks after I check to see what is going on. Things have changed. Now, because I am missing one oil change receipt, they need to be paid $1400, to further corroborate the cause of the engine failure. I haven't paid and honestly don't plan on paying them anything. To date, I have spent over $2,000 on car rental fees since my car is now sitting at the Global Hyundai Dealership.

After my Hyundai dealership performed a recall on emissions my Santa Fe Sport started having problems on cold starts. After it has set for a few hours when I would put into gear and start to driving the car acted as though it was trying to flood out. I have to feather the accelerator and drive very carefully for at least 1/2 - 3/4 miles. This is very dangerous and make me very uncomfortable driving. I took my vehicle back to my Hyundai dealer and the mechanic told me they were waiting for a recall to the recall. How stupid!!! It has been over a month and nothing has been done to fix the problem. Please advise!

NO power till car warms up for 5 minutes. It will be jerky on highway. The gas mileage is going down drastically, I was doing 32 miles to gallon and now it's 22mpg. All this is after the recall we just had performed. I have no power trying to avoid accidents, taking off from stopping. Car smells weird now.

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated that while driving approximately 35 MPH a loud noise and smoke was suddenly present coming from under the hood of the vehicle and the engine stalled. The vehicle was towed back to the home. The contact indicated that during the failure no warning messages or lights had displayed. The cause of the failure was not yet determined. The local dealer and manufacturer were not yet contacted. The VIN was not available. The failure mileage was 83,000.

Am filing a formal complaint regarding an official software update provided by Hyundai that completely corrupted the infotainment/head unit system in my 2017 Hyundai Santa Fe Sport. I purchased this vehicle from CarMax less than three weeks ago. The vehicle came equipped with Hyundai Blue Link, so I contacted Hyundai support to activate the service by pressing the Blue Link button inside the vehicle. Hyundai informed me that my vehicle required a software update because the current system did not contain the necessary software for Blue Link to function properly. A Hyundai representative directed me to Hyundai’s official update website and provided instructions for completing the update. Following Hyundai’s instructions exactly, I purchased and formatted a USB drive, downloaded the update using my VIN from Hyundai’s official website, properly extracted the files, and installed the update into the vehicle. During the installation process, the update failed and corrupted the head unit system. The display now continuously shows “Update Unsuccessful” with Error Code 106. Since the failed Hyundai update, multiple vehicle systems no longer function properly, including the backup camera, Bluetooth, hands-free calling, Blind Spot functionality, radio, map/display system, automatic headlights, and automatic radio shutoff when opening the driver door. I now have to manually operate systems that previously worked automatically. I contacted Hyundai customer support multiple times and was

I was driving on a main road at 55-60 mph with my daughter and grandchildren in the car and had a sudden loss of power. I was almost hit from behind. The check engine light started blinking. And the car went into limp mode. I had to limp it to the nearest place to safely get off the road so as not to put my family in any other danger.There is not enough shoulder on the road to pull over safely. It was very stressful. Was able to get it in someone's driveway and then eventually towed to Auburn,NY Hyundai/Chevrolet where it is currently. It would not turn over to start again. It does have battery power. I am waiting to hear from the service techs as to what they think is wrong. They advised me that there is a $199 per hour diagnostic fee. I also told them that we noticed metal flakes in the oil when we checked it. I feel I should mention that the vehicle went into limp mode a few weeks ago also and the dealership told me the knock sensor was bad. I had that replaced at that time.

THIS IS AN UPDATE TO EXISTING NHTSA ODI COMPLAINT #11735718 2017 Hyundai Santa Fe Sport, TXXI Theta II engine defect. UPDATE: On May 7, 2026, Hyundai Case Manager acknowledged in writing "Your case is important to us" and "2.4L THETA concerns" for Case #42623761. This is written admission the vehicle has the TXXI defect covered by warranty extension to 120,000 miles. I gave Hyundai 48 hours to provide written authorization for oil consumption test per their TSB 22-EM-003H. After 3 days they are silent. They refuse email communication despite documented language barrier. Current Vehicle Status: - Active DTC P0010 causing loss of power and stalling risk - Oil Consumption: 1 liter per 600km, which is 3x Hyundai failure threshold in TSB 22-EM-003H - 95,772 miles, under TXXI 120,000 mile warranty limit - U.S. Spec vehicle covered by TXXI Warranty Extension Hyundai is violating Magnuson-Moss Warranty Act by refusing to honor written warranty for known safety defect. The P0010 defect causes sudden loss of power while driving. Requesting immediate NHTSA intervention to compel Hyundai to perform warranty repair.

Immediately following the implementation of Service Campaign 9C2 and TSB 25-01-087H - ECU Update for THETA II Emissions Logic Improvement, the vehicle exhibits poor drivability (staggering/missing/hesitation) until the engine warms up. This is most noticeable just prior to the shift from first to second gear.

COMPONENT FAILED: Theta II 2.4L GDI engine connecting rod bearings. Vehicle has 95,000 miles. Engine available for inspection in [XXX] . SAFETY RISK: Engine knock + limp mode at 1500 RPM caused sudden loss of power on highway. Oil consumption 1L/700km risks catastrophic engine seizure while driving.

Hair line creak in oil pan. Creak has caused excessive oil consumption and leaks on pavement. Issue was confirmed by Antwerpen Hyundai and oil pan was replaced on 4/28/2026 at a cost of $520.00. As above reported to dealer. Problem started, 1st. noticed about 9 to 12 months.

My ABS Lights the triangle with the ! In the middle goes in and off the down hill control light and the sweet control light all go on when the ABS light goes on my oil was completely dry had to add two quarts while the engine was ticking when started and when accelerating it was making a clicking noise I still had 3000 miles before needed an oil change but like I said it was bone dry and then the drivers seat was going back and not wanting to come back up I’ve only had the car 42 days and it’s having all kinds of problems

The vehicle is experiencing a massive paint adhesion failure (white pearl paint), which is peeling off in large sheets from the hood and roof. This is a severe manufacturing defect. At highway speeds, paint flakes fly off, posing a significant safety hazard to other drivers and obstructing visibility. Furthermore, the exposed metal is prone to rapid corrosion, which compromises the structural integrity of the body panels. Despite contacting Hyundai Motor America (Case #XXX), the manufacturer has refused to provide a timely resolution or cover the repair cost of $4,650, as estimated by an authorized dealer."

Abs, traction control lights, emergency braking lights on .. tire sensors are bad. Causing intermittent issue with the lights. For 3 years I've been trying to get my ABS/traction control fixed at Hyundai, that dealership refused to acknowledge there was an issue. I had a code from a car place since I live over an hour away and they said they couldn't use it since it wasn't from them. I have an extended warranty there. Went to another dealership and was immediately told it was the tire sensors. That he used to work at the other dealership and they saw it all the time. I now see Palisades have a tire sensor issue. Heck I've been dealing with this for years, and apparently so are many other Hyundai owners, according to this Hyundai employee. Now they're trying to overcharge me and saying my warranty will only cover a quarter of what they want. My deductible is only 100 if I don't get the work done at the original place, the one that said there isn't a problem. I've had it with Hyundai. They are unsafe and don't care about customer service.

The engine on my 2017 Hyundai Santa Fe sport was deemed defective according to Downey Hyundai. They ran a diagnostic test on it and it failed the test. They offered to replace it for me at no cost to me. On December 11, 2025 the engine caught fire while the service technician from Downey Hyundai was “test driving” it in a drive-thru of 7 Leaves. He was using my vehicle for personal use when the engine fire occurred. Both Downey Police Dept and Downey Fire Dept made reports. I did file a claim with my insurance company, AAA. On 12/8/25, the engine oil light blinked once very quickly on the dash and that was it. I took my vehicle to Downey Hyundai the very next day to have it inspected.

While driving on US-rt1 in Dinwiddie Va, in my 2017 Hyundai Santa Fe Sport. I was in a collision where a vehicle pulled out in front of me at no fault of my own, and I hit that vehicle going about 47mph. the front nor rear/side air bags deployed. My body slammed into the steering wheel causing severe whiplash as well and contusions to my left shoulder and neck, as well as my wife to be who also sustained injuries to her leg/knee. Had the airbags deployed i would have not made contact with the steering wheel though-out these events.

Car is running out of oil quickly but there are no visible leaks. Have had the oil changed a couple of times since then and have had to add oil in between because the oil light comes on when I make turns. Had the oil changed at a local oil service station and they said it was almost empty.

We have a 2017 Hyundai Santa Fe with 130k miles on it. It has the 2.4 engine with known manufacturing defects. We are the 2nd owner and timely & proper maintenance was completed on it since it was new. My [XXX] driver was operating the vehicle on Interstate 75 in Middle Georgia when the vehicle started running very rough, slowed down dramatically and the check engine light started blinking. She was blessed that a large truck didn’t run her over as she tried to move to the side of the roadway. We called a tow truck to take it to the nearest Hyundai dealership- ALM Hyundai of Warner Robins, GA. They inspected the vehicle and stated that the engine had messed up and they wouldn’t replace it since the vehicle had 130k miles and outside their window for 120k mile replacement. We purchased the vehicle from the original owner in 2022. We verified that it had timely and proper maintenance on it. We were also aware of a potential engine issue but verified with a Hyundai service advisor at Five Star Hyundai in Macon, Ga that the vehicle would be eligible for engine replacement if it messed up due to a manufacturing defect as long as proper maintenance was completed. We noticed that the vehicle was significantly burning oil at around 110k miles and regularly had to put oil in it to make sure it would not run dry. We did have the safety recall performed on it for the engine knock issue that Hyundai mandated. These vehicles are a major safety hazard on the roadway and these effected engin

My vehicle was serviced for an oil change at my dealership today. The mechanics are concerned about too much oil consumption in between oil changes. They have no evidence of a leak. Prior to getting my oil changed, a red oil light appeared when I brake. The dealership had mentioned of related recalls for this problem for this vehicle model.

Component: Engine (Theta II 2.4L GDI) / connecting rod bearing-related failure risk with abnormal internal oil loss. The vehicle is available for inspection upon request (engine, oil level condition, diagnostic history, and dealer records). Safety risk: While driving on the highway (approx. 70 mph), the vehicle displayed a low oil warning, and I experienced concern for potential engine seizure/stalling and sudden loss of power, which could cause a crash. I reduced speed and sought service. This condition presents an ongoing safety risk because sudden engine failure can occur without adequate warning. Dealer confirmation: The problem was confirmed by a Hyundai dealer. After a routine oil change, the low oil warning appeared within ~1,700 miles. A Hyundai service center inspected the vehicle and documented the engine was approximately 3 quarts low with no external leaks, indicating internal loss/engine deterioration rather than a leak. Hyundai then required additional steps (combustion chamber cleaning and monitored mileage), and the abnormal internal oil loss condition persisted. Manufacturer inspection: The vehicle has been inspected by Hyundai dealerships, and Hyundai performed campaign-related actions, including KSDS/ECM update (T3G) and later knock sensor replacement. No police or insurance inspection. No crash or injury occurred. Warning lamps/symptoms prior to failure: Prior symptoms included a Check Engine Lamp with DTC P1326 (KSDS-related) documented by Hyundai service

I have maintained my car regularly. I use LOFSYNBLEND oil at 7500 mile intervals per car and oil manufacturer. At 70000 mile oil change the tech showed me that less than a quart of oil came out of the crankcase during the oil change. There were no visible leaks, no visible smoke coming out of the exhaust when I drove the car, and NO warning light. This was the first time that this issue was present to my knowledge. I am taking the vehicle to the dealer for an Official Oil Consumption Test.

Vehicle: 2017 Hyundai Santa Fe Mileage at Failure: ~129,000 miles Issue Type: Engine Failure / Valve / PCV-Related Defect Manufacturer & Dealer Both Denied Repair My 2017 Hyundai Santa Fe suffered a sudden engine failure at around 129,000 miles. The Hyundai dealer verbally told me the failure was caused by a faulty PCV valve, which is a known issue in Hyundai engines and can lead to severe oil loss, crankcase pressure problems, and ultimately engine failure. However, the printed diagnostic paperwork they provided listed a different reason for the failure, and the descriptions do not match what I was told verbally. This inconsistency makes me believe the cause is related to a known Hyundai engine defect that the manufacturer is not acknowledging. I contacted Hyundai Motor America directly, provided documentation, and requested warranty or goodwill repair assistance. They denied the claim even though the failure was due to a defective engine component and not misuse. This engine failure created a dangerous situation and appears to be consistent with Hyundai’s history of valve, oil system, and internal component defects. Given the mismatch between the verbal explanation and the written diagnosis, I am concerned the dealer and manufacturer are avoiding responsibility for a known defect. I am requesting that NHTSA investigate Hyundai for potential PCV-valve-related engine failures and inconsistent denial practices.

The engine of our 2017 Hyundai Santa Fe Sport has been significantly problematic since we first purchased the vehicle in 2017. These issues have been well documented by other Hyundai owners and have resulted in class action lawsuits. After purchasing our vehicle new from dealer, it began experiencing difficulties, consuming large amounts of oil, spewing smoke from the tailpipe, leaving metal shavings in the engine oil, failing to start, and at times going into a protection mode to keep the engine from further damage and restrict speed above 15 miles per hour. The vehicle had to be towed multiple times at our own expense. Hyundai delayed replacement of the engine for months resulting in thousands of additional miles being put on the vehicle under unsafe operating conditions. Hyundai reluctantly replaced the engine in February of 2024. What appears to not be well-documented in NHTSA complaints are the impacts of these engine issues to other Hyundai components and parts. Hyundai replaced our original engine but did not replace the engine’s catalytic converter. 20 months later, the check engine light has illuminated again as a direct result of oil sludge and buildup from accelerated oil consumption. In November 2025, the dealership identified the fault code P0420 for catalyst efficiency system below threshold. We have experienced a loss of acceleration, increased fumes, and decreased fuel efficiency as a result of the catalytic converter failure, and believe the vehicle is no lon

The contact's mother owns a 2017 Hyundai Santa Fe Sport. The contact stated that while the owner was driving the vehicle at an undisclosed speed, the vehicle stalled. No warning lights were illuminated. The contact stated that the vehicle failed to restart. The vehicle was towed to the dealer, where it was diagnosed with loss of compression in the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. Additionally, the contact stated that the engine failure was a known failure. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 114,000.

We had the oil changed like always and shortly after I was checking the oil and it was not even on the dipstick so I added some and checked for leaks anywhere did not see any than we had problems with it barely accelerating so took it to dealership the performed the anti knock sensor upgrade for free and when I asked about the oil consumption they said that I needed to do a engine clean and all kinds of stuff came to like $400 so I had them do it because I can not have my wife stranded somewhere after all that they changed the oil again that was another $80 they said to bring it back at 1000 miles for them to check brought it back at 700 miles already used 1.5 qts they said engine is junk but cannot get anything done about because it had at the time 120000 miles

The vehicle’s engine is experiencing excessive internal oil consumption that poses a serious safety risk while driving. After a routine oil change performed by an authorized Hyundai dealer, the engine oil warning light illuminated within about 1,700 miles. Upon inspection by another Hyundai service center, technicians confirmed that the engine was burning oil abnormally and was three quarts low, with no external leaks. This issue was documented in the dealer’s repair order, which states “vehicle is burning excessive oil.” The problem has been reproduced and confirmed by a Hyundai dealer. The vehicle is equipped with the Theta II 2.4L GDI engine, which is already covered under Hyundai’s KSDS (Knock Sensor Detection System) extended engine warranty due to known internal mechanical defects such as bearing wear and oil consumption. Despite this, the manufacturer has declined to replace the engine. The excessive oil burning occurs rapidly and triggers the low-oil warning light while the vehicle is in motion, creating a risk of engine seizure and sudden loss of power that could lead to a crash. The defect remains unresolved. Warning lights for low oil level appeared multiple times beginning in 2025, shortly after the KSDS update and knock-sensor replacement.
