2018 Hyundai Tucson complaints

My car on the expressway wouldn't go over 40 and this was happening intermittently so my car was unsafe. No check engine light but it was just at the dealership for an oil change. Has. been an ongoing problem since I bought the car! Smells, gets hot!

Excessive oil consumption (failed 3 tests) now adding two quarts a week.... Transmission shifting issues (already had a replacement at 65,000 miles. Hesitation with acceleration. AWD and can barely make it up my driveway. Rpms rev when trying to go slow. Already needed a moonroof replaced because the motor died. USB randomly disconnects and reconnects for GPS.

The contact owns a 2018 Hyundai Tucson. The contact stated that while driving at various speeds, the vehicle almost stalled. The contact stated that the check engine warning light illuminated and was flashing off and on. The accelerator pedal was depressed; however, the vehicle failed to respond as needed. The contact pulled over to the side of the road, and the vehicle remained running. The contact waited for a while and then shifted to drive(D) and was unable to accelerate above 30 MPH. The contact stated that the failure was a recurring failure. The vehicle was taken to a Parts Store and was scanned, and DTC: P1326 was retrieved. The contact had not taken the vehicle to a dealer or to an independent mechanic. The vehicle was not diagnosed or repaired. The contact was no longer driving the vehicle. The manufacturer was not informed of the failure. The failure mileage was approximately 102,000.

Shortly after purchase, I had an oil change and vehicle inspection performed. I was informed that my engine may have an internal defect causing it to burn oil excessively. I later took the vehicle to a AAA-approved Hyundai service center, where they confirmed that the engine is burning oil due to a known manufacturer issue and that it is not the result of owner misuse or neglect. I have been quoted approximately $11,000 for a replacement engine, which is an extreme and unexpected cost for a recently purchased vehicle in otherwise good condition.

I purchased this car [XXX] as a CPO vehicle from a Ford dealership. By [XXX] the oil pressure light would flicker and it was clear the car was burning a lot of oil between changes. On 8/22 an oil change was completed at dealer. On [XXX] the oil pressure light flickered and it was three quarts down. An oil consumption test was started at 112,000. On Sat [XXX] while driving to dealer for oil check, the car began shuddering violently and the check engine light came on, and went into limp mode. I was on a dangerous mountain pass at the time and it could have been a major issue. The day before a tractor trailer had almost run me off the road, if my car had stalled then I might not be here. Hyundais have a known issue with oil burning and engine damage. Right now I am stuck in a 14K loan with a car that is unsafe to drive. I am not sure what the dealer plans to do, or what the diagnosis is, but its clear these engines are not safe.

My 2018 Hyundai Tucson SEL PLUS limited showed a flashing check engine light on 10/14/2025 and basically gave up acerating pass 60mph while I was driving , I pulled over and called the dealership where I bought it from they told me to drive it in, I did and they did an oil change and filled up, we then began the oil consumption test which I brought it back yesterday 10/24/2025 and was told the whole engine needed to be replaced due to a major oil consumption problem, they advised me to bring it the Hyundai dealership to get it fixed they rudely told me no we can't fix this, we would have to wait for it to flash the check engine light again and it would have to fail a bearings test before it can be fixed and still have a possibly of it not fixing. only confirmed by the lot I bought it from since Hyundai refused to look at it.

The contact's sister owns a 2018 Hyundai Tucson. The contact stated that while his sister was driving at an undisclosed speed, the vehicle briefly jerked and jolted, prompting her to pull over to the shoulder of the roadway to turn off the vehicle. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed failures with all four fuel injectors and the injector assembly. The vehicle was repaired, but the failure reoccurred. The vehicle was taken back to the independent mechanic, who then diagnosed a failure with the catalytic converter. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 78,563.

My 2018 Hyundai Tucson 1.6 Turbo (VIN [XXX] , 113,000 miles) burns oil excessively and was deemed to need full engine and turbo replacement ($15,382.95). Hyundai refuses responsibility (case #XXX). This is a widespread defect that causes potential loss of power while driving. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2018 Hyundai Tucson has excessive oil consumption. Burns multiple quarts of oil per 1000 miles. Hyundai refuses to remedy the oil consumption. Oil consumption has also led to having to replace the catalytic converter due to oil burn off.

On October 13th 2025, we were involved in a serious collision while driving our 2018 Hyundai Tucson. The vehicle was struck from behind and spun into a semi-truck, totalling the vehicle. Despite the forward and lateral collision to the semi-truck, no airbags deployed at all during the accident. This resulted in the Tucson driver striking his head on the steering wheel. Our 5-month old son was also on-board the vehicle in his car seat. While everyone walked away from the accident, both adults passengers had whiplash/minor neck injuries that could have been mitigated by airbags deploying. We have serious safety concerns about Hyundai's airbags because of this incident.

I am filing a complaint under the NC Unfair and Deceptive Trade Practices Act (N.C. Gen. Stat. § 75-1.1) regarding Hyundai’s handling of my 2018 Hyundai Tucson (purchased new May 2018). Since 2019, the vehicle has had repeated headlight failures (at least 12 bulb replacements), persistent “bulb out” warnings, and eventually melted wiring requiring headlamp assembly replacement in 2025. These issues were first reported in April 2023 under warranty but dismissed as “could not duplicate.” Hyundai later attempted to deny coverage, only replacing the assembly after escalation to Corporate. At the April 2023 visit, I also reported a rear noise that Hyundai dismissed. After warranty expiration, it was attributed to a leaking shock. Shocks were covered under warranty; failure to act while coverage was active left me unprotected. In May 2023, the engine failed due to oil loss and lock-up. Hyundai retained my vehicle from 5/15–6/30/23 for engine replacement. From Aug–Sep 2025, the car was held an additional 24 days, with no permanent fix for the electrical defect. Overall, my Tucson has been out of service for 60+ days between 2023–2025. Examples of unfair/deceptive conduct: Dismissing documented defects under warranty, only acknowledging later after expiration. Attempting to shift labor costs onto me in Jan 2025 despite warranty obligations. Returning my vehicle with only ~39 miles of gas after requiring me to return a loaner full. Repeated misdiagnoses and delays despite video and do

Van Hyundai Dealership in Carrollton, TX has confirmed excessive oil consumption causing catalytic converter failure that results in the engine stalling and unable to accelerate. We’ve already replaced the catalytic converter once in 2024 because it was full of oil and causing engine failure. Less than a year later (less than 10,500 miles) the same problem was reproduced. The dealership refuses to replace our engine due to the engine defect. This problem directly impacts the engines ability to perform, unable to accelerate on the interstate, and engine stalling which directly impacts our safety and puts our family into a life threatening situation when the engine fails on the highway. The engine has a defect that Hyundai refuses to address. There are no warnings or engine lights that appear beforehand which is extremely concerning and a liability. Hyundai motor company is corrupt.

The contact owns a 2018 Hyundai Tucson. The contact stated that while driving at 60 MPH, the vehicle lost automotive power, with the check engine warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed, and the contact was advised that there were metal shavings found on the camshaft sensor. The contact was advised that the camshaft sensor, oil flow solenoid, and variable tee valve were faulty and needed to be replaced. The vehicle was repaired; however, the failure reoccurred 3 months later. The contact stated that while driving 60 MPH, the vehicle failed to accelerate as needed, with the check engine and oil light illuminated. The vehicle was taken to a local dealer, where the vehicle was diagnosed, and the contact was informed that the engine was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 56,942.

Over the past nine months, I’ve been experiencing ongoing issues with my 2018 Hyundai Tucson engine and transmission. After four consumption tests and a flush confirming that the engine is burning between 0.8 and 0.3 liters of oil for every 1,000, I was informed Hyundai refuses to either repair the issue or conduct testing to determine the cause. The timeline is summarized below: •February 2025 – I was told by [XXX] my vehicle simply did not have enough oil after the last oil change; •March 2025 – I was informed an initial consumption test needed to be completed; •May 2025 – a second consumption test revealed the engine was burning more than 1 liter per 1000 and a flush was completed; •July 2025 – a third consumption test was completed, revealing that while the engine was excessively burning oil, it was not currently at 1 liter per 1000 based on that test; August 2025 – the oil light came on & I was instructed to put a liter of oil into my vehicle to make it to the certified dealer for next steps. The next steps were another consumption test. Unfortunately, because I was told to add oil to make it to the dealership, I was then informed that this added oil would alter the testing, and we had to start over. •September 2025 – I am now awaiting the results of the fourth consumption test. I have receipts for every 6 months or 7,500 of service since purchasing the vehicle., Despite the engine and transmission being under warranty, the dealership has refused to conduct testing to de

I took my car in for a daily oil change and inspection, where I learned that there was no oil is in my car after coming in 5k miles before as I have been religious about oil changes. I came in on Saturday September 20th for an inspection and was topped off with 3 quarts of oil but am now back in the shop Monday September 22nd to test the oil. The oil that was checked came out Black.

PARKED SUBJECT CAR IN GARAGE AT APPROXIMATELY 11:15 AM AFTER TURNING OFF VENTILATION FAN AND CUTTING ENGINE OFF, WHICH DISPLAYED "OFF" AT DASH BUTTON. AT APPROXIMATELY 7 PM (SAME DAY) WENT INTO GARAGE TO RETRIEVE ITEM AND HEARD THIS LOUD NOISE SIMILAR TO AN ELECTRIC CLOTHES DRYER RUNNING - WASN'T DRYER. AS I GOT CLOSE TO CAR, HEARD THIS SAME SOUND. RAISED HOOD AND COULD FEEL AIR MOVEMENT . CHECKED ENGINE OIL - NOT WARM. BACKED CAR OUT OF GARAGE INTO DRIVEWAY OUT OF SAFETY CONCERN IN CASE OF FIRE. WILL CONTACT HYUNDAI MOTORS TO REPORT THIS INCIDENT AND FOR INSTRUCTIONS WHAT ACTION I SHOULD TAKE NEXT. THIS IS THE FIRST INCIDENT REGARDING MY CAR"S ELECTRICAL SYSTEM. DURING THE 3 HOURS DRIVING THAT MORNING, I HAD NO WARNING SIGNS ON DASHBOARD OR FAN MOTOR RUNNING AFTER TURNING ENGINE OFF. HAD MADE 3 STOPS AND ENGINE START UPS DURING THAT TIME

The contact owns a 2018 Hyundai Tucson. The contact stated that while driving approximately 15 MPH, and slowing down to make a right turn, the vehicle almost stalled and lost power. The contact stated that the check oil warning light was flashing on and off. The contact depressed the accelerator pedal, and the vehicle failed to respond. The contact was able to pull over and shift into park(P). The contact had not turned the vehicle off. The contact called her father. The father arrived, and the vehicle was turned off. The contact stated that her father checked the oil dipstick and saw that the oil level was extremely low. The contact stated that two quarts of oil were added. The contact drove the vehicle to a local dealer. The dealer diagnosed and determined that a gasket on the oil filler tube was not correctly seated, and the catalytic converter needed to be replaced. The contact stated that prior to the recent failure with the catalytic converter, the catalytic converter had been replaced approximately 1 year and 8 months prior. The dealer also recommended that the engine be replaced. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 102,000.

My engine stopped and locked up. It happened while I was driving on the highway/interstate. Yes it has been diagnosed by the dealership. There was no warning lights prior to the system failure.

Drivers seat seat does not go up it stays in reclined position No it has not been inspected by the manufacturer No warnings was put in recline position and could not lift up happened a week ago I have to drive to work and it is unsafe driving in this position. I did take it to an autoshop and they said that it could be electrical which they were not equipped to do.

I own a 2018 Hyundai Tucson with 87,000 miles that consumes about four quarts of oil per 1,000 miles. I first noticed the problem at 51,000 miles, despite regular maintenance. The issue has worsened, repeatedly damaging spark plugs and causing the car to seize. Hyundai has denied my request for a replacement engine because I am the second owner. I bought the vehicle at 26,000 miles, believing it carried the 100,000-mile warranty. I was never informed that coverage drops to 60,000 miles for second owners. I have maintained the vehicle with oil changes every 3,000 miles, yet it remains unsafe to drive long distances. This defect presents a serious safety risk, and Hyundai has not provided a resolution.

My connecting rod came apart and went through the oil pan while I was on the highway. There were no engine or oil lights until the engine was already smoking and no longer accelerating luckily I was in the far right lane already and was able.to coast to safety. Hyundai is also refusing to honor my warranty. It requires a completely new engine. So this was a catastrophic engine failure with no warning.

There is a very well known issue with Hyundai (and Kia) and oil consumption issues, no recalls have been issued yet and I am another person dealing with this without any real support from Hyundai to solve the issue. In 2024 I did an oil consumption test, they found it was burning oil excessively and I had to pay $700 out of pocket for a cleaning they recommended. Afterwards it was burning only 1 quart every 1k miles which they said is acceptable so we moved on. Less than a year later I am still dealing with this issue only it has gotten worse, I am burning 5-6 quarts every 1k miles. I do keep up with my oil changes, I now have to check it and top it off almost daily, and even without being a car expert I know that something HAS to be done... why aren't there any recalls yet? Despite keeping up with my maintenance, there are other issues that can be related from this issue, including the engine stalling or skipping which is a safety issue when driving.

I was driving on the highway, about to change lanes, when I looked in my rear view mirror and saw black smoke coming from my appeared to be my exhaust. I immediately started to pull over, and that is when the oil light first appeared on my dashboard. By the time I had put the car in park, the check engine light had also appeared. After calling my boyfriend and a tow truck, I exited the vehicle and noticed a large pool of oil by my front tire. With the car on the tow truck, I could see oil continue to drip out. The car was towed to the local Hyundai dealership. Since this occurred on a Saturday afternoon, the service dept. was closed, and Hyundai called me on Monday, Aug 11, 2025 to explain that i should contact the auto mechanic that last changed my oil, as the oil plug had fallen out, and my engine had seized. (Had I not noticed the smoke right away, I could have been in an accident on the highway when the engine seized.) I explained to Hyundai that I had my oil changed 3,000 miles ago, and hadn't seen any indication of oil leakage, nor had the oil light come on prior to the incident on Aug 9, 2025. Hyundai insited I contact the oil change mechanics as it was clearly a craftsmanship defect, not the fault of Hyundai parts or material. Hyundai provided photos showing the oil plug was still laying on the block. I visited Superior Auto (mechanics that did the previous oil change) and they also deny responsibility due to the fact that the car drove fine for 3,000 miles without an

I have regular oil changes (every 3k mi) and every time I go get say there’s no or low oil. At the beginning of July my engine coil in column 3 failed and I had all four coils and spark plugs replaced. Since the replacement my engine is still consuming a quart of oil per week

I am submitting this formal safety complaint regarding my 2018 Hyundai Tucson. The vehicle has 101,900 miles and has been well maintained. Recently, it began experiencing severe performance issues, including difficulty accelerating and consuming oil at an abnormal rate. The dealership diagnosed the problem as a failed catalytic converter with an estimated repair cost of over $8,000. While Hyundai has an active recall on the engine for this model year, they have stated that my specific problem is not covered, despite the fact that the catalytic converter failure appears to be directly related to the engine defect. The oil consumption and acceleration issues raise serious safety concerns, as the vehicle can lose power unexpectedly while driving. I am a teacher, a parent, and have one child with special needs. I have no other form of transportation and am still making payments on a car I cannot safely drive. Hyundai’s refusal to address this issue as part of the known recall leaves me with an unsafe and inoperable vehicle through no fault of my own. I believe this matter warrants further investigation by the NHTSA, as it suggests that related component failures stemming from the defective engine are not being adequately addressed, leaving owners at financial and safety risk. I respectfully request that the NHTSA investigate whether Hyundai is failing to address a known defect’s full scope and to take appropriate action to ensure the safety and fair treatment of affected consumer

29 days after I bought a 2018 Hyundai Tucson. The vehicle started making a ticking noise and stopped accelerating. I called the dealership and they said we didn't get a warranty. I said no that isn't correct, no warranty was offered and after seeing ALL the known engine problems I understand why ken ganley in medina wouldn't offer one. Now not even a month into having this vehicle, I have a brand new 5 year loan and a vehicle that won't move until I put a new engine in it and the dealership won't do anything for me. This is the worst experience I have ever had purchasing a vehicle

It's an engine failure. The car died in the middle of the rode at a traffic light with busy traffic flowing. It was confirmed by a independent service center. No one other an the independent service center has inspected it. There were no warning lamps or messages before failure.

Since I purchased the car in 2018 I took great care of it, keeping the services going on time. But recently in October 2024 even tough I did services the oil service’s sign keep on showing up. I then schedule an appointment with a dealer ship near my area in January and they told me that they were no oil in the car. But I show them the date ans mileage on my stickers I specified that is the reason I am here and to double check for me for filtration because something is wrong, they told me that the car was fine. Days after I had to go in my regular service place for another service and on May I drove the car from Massachusetts to New York and in the middle of the way car start shaking, making noise and when I drove it to a shop they diagnose a failed engine. I left the car in Goshen NY in a Hyundai dealer ship and they told me a valve un the engine was burned and that where the problem came from . They said , they fixed it. A friend pick up the car and 30 mnt driving it police came to rescinde her in the highway, they then told me that’s it’s was a failed engine and days after ask for services record, I provide the last 6 times , they asked me from 0 until today. The shop were I take care of the car don’t keep record from so long. Talking about 2018. They said they won’t fixed it without those record . The car is still under warranty with 71321 miles and I have it for 7 years.

My 2018 Hyundai Tucson 2.0L GDI engine with only 79,000 miles was "knocking" and wouldn't accelerate. We pulled over and towed the vehicle to the local Hyundai Dealer who declared "oil level good but failed bearing clearance test". Diagnosed with a rod and bearing failure. They submitted to Hyundai Motor Warranty the vehicle needed new engine. They declined. I know this is covered under the Hyundai Engine 2 Class action lawsuit with the extended 15 year/150,000 mile warranty as a result of the catastrophic engine failures. I have all oil change service records for every 5,000-6,000 miles while I was the second owner, as well as, have obtained another from the dealer who bought it from a rental/lease company starting at 14,000 miles. Hyundai Corporate is claiming "exceptional maintenance neglect" because of one missing oil change record from the rental company that I may not be able to obtain as the paper trail for the rental car company only states first owner was rental/fleet

After an impact with a large buck (deer) on a main highway while traveling 70 miles per hour, the airbags failed to deploy.

The contact owns a 2018 Hyundai Tucson. The contact stated while driving 70 MPH and depressing accelerator pedal, the vehicle started to decelerate. The contact pulled over to the right side of the road and turned off the vehicle. The contact waited for two minutes and attempted to restart the vehicle; however, the vehicle failed to respond as needed. The brake warning light was illuminated. The vehicle was towed to an independent mechanic where it was diagnosed with a misfire in cylinders #1 and #2. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 20V543000 (SERVICE BRAKES, HYDRAULIC); however, the VIN was not included. The manufacturer was notified not notified of the failure. The failure mileage was 177,000.

Component: Engine Vehicle: 2018 Hyundai Tucson VIN: [XXX] Approx. Mileage at Failure: 79,413 miles Incident Date: [XXX] Where It Happened: While driving [XXX] At 79,413 miles, my 2018 Hyundai Tucson (VIN: [XXX}) suffered complete engine failure without warning. The vehicle had been properly maintained (records from Express Oil Change & Tire Engineers), and was operating under normal conditions. The dealership diagnosed total engine failure and quoted $7,723.88 for replacement. They are not replacing the engine with the same type, which may indicate a known issue. There are no active recalls, but similar engines in Hyundai vehicles from this era have been subject to recalls and warranty extensions. I believe this may be due to a manufacturing defect. No injuries occurred, but the failure posed a safety risk while in traffic. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On April 12, 2025, my 2018 Hyundai Tuson which only has 99,000 miles started stalling out at random speeds. The vehicle stalled going up a hill and would not accelerate it would also not go past 55-60 miles per hour on the highway. There were no check engine lights or codes on the dashboard. The vehicle is also burning oil on 2 occasions when having the oil changed. I feel like my life and others is in danger because the vehicle is stalling at random speeds which could cause a major accident due to this issue. I could be hit by another vehicle while trying to accelerate or merge on the highway. I reported the oil consumption last November and I contacted Hyundai customer care who issued a case number in May 2025 for the stalling issue, they instructed me to take it to the Hyundai dealership to be diagnosed. There is a recall out, but they said my vehicle is not included in it. I took the vehicle to the dealership, and they confirmed the vehicle was stalling and would not accelerate and were able to reproduce the issue. They informed me the vehicle needed a new transmission, and the vehicle only has 99,000 miles. Hyundai and the dealership declined to add the vehicle to the recall campaign for stalling vehicles. I had to cover the cost of $3,000 for a new transmission. I picked the vehicle up on June 6,2025 with the new transmission installed and it is still stalling and won't accelerate past 45 miles per hour.

I noticed my vehicle was burning through oil, initially indicated by a P011 code, when I called Hyundai they said its often a symptom related to low oil pressure. After oil changes, the code would clear, but it returned multiple times, and on two occasions, the dipstick showed no oil when checked. Despite staying current on oil changes and maintenance, I was dismissed as excessive oil burning being “common” for this engine. After recent recall updates at the dealership, a technician confirmed excessive carbon buildup and that my catalytic converter was beginning to plug. I inquired about an extended warranty offered due to the knock sensor installation but was told it only covers rod bearing failure. Hyundai Corporate echoed this, stating no coverage until catastrophic engine failure occurs, despite the ongoing damage from oil burning and converter clogging. Since my visit to the Hyundai dealership, the symptoms have rapidly escalated. Now, my vehicle is extremely loud and acceleration is poor. It takes a long time to get up to speed, and I worry about driving it as it may result in an accident.

While starting and accelerating my 2018 Hyundai Tucson, I began hearing abnormal engine knocking and noticed rough performance. I took the vehicle to an authorized Hyundai dealership, where they diagnosed an internal engine defect. They confirmed the engine issue but refused to cover the repair, citing that I’m not the original owner—despite public information stating that Hyundai’s extended engine defect warranty (related to known bearing failures) applies to all owners for up to 15 years/150,000 miles. This creates a major safety concern, as I drive long distances on highways daily and fear the engine may seize or fail at high speeds. The vehicle remains at the dealership and is currently undrivable. I’ve submitted proper maintenance records, and the issue has been escalated through Hyundai Consumer Affairs and the Better Business Bureau. This appears to be a widely reported engine defect that Hyundai is not consistently addressing. The lack of coverage and delay in resolution places drivers at unnecessary risk.

I was driving my car and the engine started knocking and when I stopped the car kept stalling and losing power especially going up a hill. I had oil in the car. I bought the car to a repair shop and the mechanic advised me to go to Hyundai because they’re having problems with the engines in the Tucsons. I found out they extended the warranty from 100k to 150k so I’m covered I thought. They started diagnosing my car and they said the engine needs to be replaced. They contacted Hyundai corporate to dis cuss this. Corporate said they’re no t responsible for this because there was sludge in the engine. The car has 103k miles on it. The diagnosis charge I owe so far is about 400.00 Hyundai corporate wants further diagnosing of the engine. The dealership said Hyundai corporate said I have to pay the additional diagnostic charges of approximately 900.00 before they’ll determine the outcome of my claim. I don’t think it’s fair at all. I believe they should be paying for information they’re requesting. I’m having a hard time with Hyundai corporate with this runaround they’re giving me. I do t l ow what else to do? I can’t afford to pay for an engine replacement that they should be responsible for this problem. I hope I’ve proved enough information. Thank you sincerely.

The oil sensor doesn't illuminate the light on the dash when the oil level becomes low. The only warning is when it becomes really low and then the check engine light will appear. It's a safety concern due to the engine possible failure and or damage may occur at that point if continuing driving happens. This causing the engine to stall and loss of control of the vehicle. Which could lead to a vehicle crash resulting in injury or death to the occupants and or others nearby.

The paint on my 2018 Hyundai Tucson began peeling off the side mirrors and the shark-fin antenna on the roof. I have found that many other Hyundai owners are experiencing the same issue. It appears to be a widespread manufacturing defect related to improper paint adhesion, and I believe it should be addressed even though my vehicle is out of warranty.

The white paint on the hood began to flake off. Currently, the missing paint is about 3 inches in diameter. There is an appearance of paint bubbling on the roof of the vehicle and in the hood. The vehicle was taken to dealership, but a member of their service department conveyed nothing to be done because no current warranty on it. No outside company has reviewed the issue.

The sunroof on my Hyundai Tucson will not close. Seems to be a motor problem. I brought it to a mechanic and it will be a lot of money to fix. I have looked up if this is a common problem and it’s all over the internet. I am not sure if it should be a recall. Thank you.

1.What component or system failed or malfunctioned, and is it available for inspection upon request? Engine is failing/malfunctioning. Yes it is available upon request 2. How was your safety or the safety of others put at risk? No oil can cause an engine to overheat and/or catch fire. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was confirmed by Hyundai of Medford. Oil consumption test was completed. Preauth was submitted for a new engine and was denied. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, inspected by manufacturer (Hyundai of Medford). No leaks or other issues that could cause this were found. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, no warning lamps or messages were shown or sent. Even when low on oil. Consuming oil extremely quickly. Oil change was completed and I was only able to drive 700 miles before I was low on oil. I have history of oil changes and top offs every 1000 miles for about a year. It has only gotten progressively worse. Hyundai of Medford Confirmed the issue and confirmed there were no oil leaks or other issues that could cause this. They recommended I request a new engine for Hyundai. I submitted the Pre-Authorization and it was denied. After more research I have found that thousands of people have had the same exact issue w

1.The engine is consuming oil excessively. 2 and 3. I was informed during a service visit that this is a common problem. I asked how to get it fixed and was advised to lock the engine up. I informed the service advisor that I would not lock the engine up and told him I have a [XXX] son. I told him I'm trying to do everything I can to prevent that very scenario. 4. Yes, I will provide records. Additionally, a class action lawsuit was filed in California under their Lemon Law. Do a quick google search. Everyone I have spoken to at the dealership has confirmed they are all well aware, however they can only do what corporate allows under the Warranty. I am the first and only owner supposedly covered until 100k miles. This problem began at 79k. I'm at 86k and still struggling to get anything moved forward. 5. Unknown 6.

My daughter‘s car was in park and still running and she got out of the car and went to the back of the car opened up the hatch cleaned her window went to the side of the car passenger side went to go get out her lunchbox and the car ran over my daughter And crushed her left side and tore off part of her face. The car came out of park on its own in my driveway and I have a video of this from my camera. She was taken obviously to the hospital by ambulance and she sees a plastic surgeon every week now this just happened March 5. Something is not right. The car shouldn’t have ever come out of park on its own in order for it to come out of park and go backwards you need to press your foot on the break and put it in reverse it reversed on its own onto my daughter.

In late September of ‘24 my husband was driving our oldest to school when my 2018 Hyundai tuscon seized mid drive with our son in the back seat with no oil or engine light warning. Husband inspected the oil and I was still full. A Hyundai dealer towed at their expense in October, diagnosed an engine failure. Denied me service since my extended warranty expired and I didn’t have the KSDS update. I wish they would as I still owe on the vehicle and I’m out of work. Making this complaint is to only spread awareness that 2017 Tucson with the 2.0 L engine had an engine failure connecting to rod bearings. My 2018 has the same engine type and failure as the 2017. Hyundai Corp fails to recognize the problem. My 2018 didn’t fail due to lack of oil changes as I can I prove that. My 2018 failed on Hyundai’s fault. Now my car sits at the dealership in Anchorage, Alaska and I still owe 9k and I live in Fairbanks, Alaska. 360 miles away from me.

74,000 miles Excessive oil consumption, 1 quart per 1000 miles. Low oil pressure warning. Oil warning light, repeated and various codes. Noticeable ticking/clatter at startup. Not included in current recalls.
