2017 Hyundai Sonata complaints

My Hyundai consumes oil and I have to put oil in it every two weeks! Also my ignition coils has had to be changed 4 times. Also check engine light just came on code saying catalytic converter or oxygen sensor changed oxygen sensor a couple months ago. I purchased it brand new and as soon as I got over 100,000 miles nothing has been going good since then please help also my paint on the top of the car is starting to peel. Will never buy a Hyundai again.

I am writing to request a Goodwill replacement. My car is burning oil faster than I can put it in. The engine heats up so bad that I feel it could catch fire at any time. I loose acceleration because of this, its an extreme safety hazard for myself and other motorists on the road. I am just now finding out about the issues Hyundai sonatas are having with this said problem. I would like it fixed asap.

My 2017 Hyundai Sonata has a major oil consumption problem. The car does not leak oil. It burns oil average 3000 miles. I have to add 5 to 6 quarts of oil every time I bring it to the shop and ask about it they tell me Hyundai has a problem with one of their engines, I see the recall on other models, but not my model. it’s been ongoing for about a year.

Engine started making a noise and then the car died and would not start. We were on the highway service road when the car died in the middle of the road. We took the car to the dealership and they confirmed the vehicle engine has seized up. This is covered under warranty. The manufacturer denied the claim because of a sensor recall in August 9, 2018. We purchased this car used on July 11, 2018 and never received the recall notification for this sensor. The manufacturer is refusing to repair the engine that is under warranty.

The airbag light has been on for years. Also, the controllers on the steering wheel stopped working, first left side, 6 months later followed by right side. I’ve been told it’s due to a faulty ring inside or under the steering wheel. Worried to drive with faulty airbag.

1.Sunroof disengaged from car. yes 2. Glass falling from car. Glass could have landed inside car, killing or injuring driver. Glass could have landed on any car behind the sonata killing or injuring occupants in that car. 3. Unknown 4. No 5. No

Premature rod bearing failure at 126,750. Dealer said there was extended warranty for this failure. Turns out that Hyundai denied this because they say Recall 953 was not done. This does not reflect what I show, I show this a Service Program and probably a notice does not get sent out. I have gotten an estimate for $7848.50 for engine replace. I do not agree with this decision since it is a know problem with multiple class action lawsuits.

All documents are attached as it is many separate incidents that ended knock from motor and minutes later, a piston shooting through the engine block which is what made the car inoperable

I am writing to request your assistance in enforcing the terms of the class action settlement and extended warranty coverage for my 2017 Hyundai Sonata (VIN: [XXX] ). Despite clear evidence of a defective Theta II engine, Hyundai Corporate has refused to authorize a full engine replacement unless the engine “blows” completely. This directly conflicts with the express terms of the “In re: Hyundai and Kia Engine Litigation” settlement, which requires Hyundai to cover any engine exhibiting failure‐mode symptoms. Below, I have summarized all relevant facts, diagnoses, and correspondence. I purchased this Sonata used from Oakes Kia (Kansas City, MO) in May 2023. At the time of purchase, the vehicle had 77,000 miles. To my knowledge, I am the third owner of this vehicle. Since I bought this car, I have followed the manufacturer’s recommended maintenance schedule: All routine oil changes (every 5,000 miles, or sooner) at Oakes Kia, plus one oil change at Northtowne Hyundai in April 2025. The engine currently has approximately 98,650 miles. I have driven it about 1,000 miles since December 2024 to avoid further damage and due to the danger, it puts me and others in on the road. Since December the vehicle has had persistent shaking, hesitation on acceleration, strong odor, and illuminated Check Engine Light. Car condition has worsened since last oil change and even after coil packs and spark plugs were replaced, there was no improvement. The last oil change was done at Oakes Kia along

Steering wheel warning light comes on traction control light comes on. Steering becomes difficult

I purchased this car in 2018. Noticed it would be low on oil frequently by year one of having it I took in in for regular maintenance at the dealer by year 2 car began giving me more issues with oil and engine I have had the manifold replaced and other parts in the engine several times and keep running into the same issues and from what I found out I’m not the only one dealing with oil consumption issues I was told by the dealer this is a regular issue with this car and that Hyundai will not cover it I feel it’s very unfair to the consumer that they did not disclose this to me when I explained I needed a dependable vehicle because I had a disabled child I have put so much money in this vehicle I could have bought a new one by now

Engine seized on me, lurched forward, then engine light starting flashing and I could barely accelerate anymore. Had to go very slowly to make it home. My local autoshop says this is very common with Hyundai's and there was a recall for bad engines for this.

My car is burning a lot of oil to the point I have no oil in my car and that’s bad

2017 Hyundai Sonata having severe oil consumption issue. Having to top off with a quart of oil every 500 miles. Was purchased last June and has been a nightmare since. We contacted Hyundai consumer affairs and they opened a case and made an appointment for us to go to a local Hyundai dealer. The dealership told us we didn’t qualify for oil consumption test be cause we are second owners and the vehicle had 62,000 miles on it. We did purchase an extended warranty when we bought the car but they won’t cover oil issue. Local mechanic won’t touch it and refers us to Hyundai dealer. Just getting so frustrated and worried about car safety and engine damage. I read on another sit that Hyundai issued an oil consumption recall in 2025 but our vehicle is not listed. Please help us.

My car was recalled because of the paint chipping. I had it fixed however it is still chipping in more spots. I'd like it fixed considering I have paid over $27,000 and still owe $12,000 more. It would be nice to still have a decent car after I finally pay it off. I'd appreciate the help.

Hood latch won’t latch and hood opens while driving.

The car went into limp mode activated by the knock sensor. Audible knocking noises were emitted. Hyundai dealership replaced knock sensor. Car drove 63 miles before knocking noise repeated and car went into limp mode. Hyundai dealership requested new engine as problem is covered by extended warranty for known issue. It has been declined by corporate office. Car is at dealership and unsafe to operate.

The contact owns a 2017 Hyundai Sonata. The contact stated that the engine was consuming an excessive amount of engine oil. Additionally, the engine was leaking oil onto the ground, and smoke was coming from the engine compartment while driving. The vehicle was taken to Walmart for an oil change. The contact stated that after the oil change the engine consumed two and a half quarts of oil after driving a thousand miles. The vehicle was taken to the dealer, who performed an oil consumption test, and the engine passed the test. The vehicle was not repaired. The contact stated that the failure persisted. The manufacturer was made aware of the failure and a case was filed. The failure mileage was 92,672.

My paint is peeling and bubbling all over the car. The paint is chipping in multiple places.

The 2017 hyundai sonata 2.4L excessively consumes oil. I constantly put oil in my car. My fear is that I will have a critical engine failure during commute and will be fully responsible for replacing the engine even though hyundai motors designed a poorly built engine. Every time I search Google about the make and model it is always hundreds of other hyundai sonata owners with the same problems and fears that their car will break down or have already had their engine replaced. I would like to see an investigation take place on the 2017 hyundai sonata 2.4L engine. It is poorly designed and consumes more than enough oil in a short amount of time to cause engine failure.

Engine burning oil like crazy never had to put so much in for any other car. Risk of engine lock without enough oil also sets of the knock sensor. Every time I get an oil change they let me know that I’ve burned most of my oil and that it’s low so I just started doing my own oil topping it off. Problem has been ongoing since I got the car.

I am writing to file a formal safety complaint regarding my 2017 Hyundai Sonata which suffered an unexpected engine seizure on January 22, 2025, while my daughter was driving. The incident occurred without warning and left her stranded in a hazardous location, putting her in immediate danger. This appears to be part of a wider, documented issue affecting Hyundai vehicles. My understanding is that engine failures—particularly in Sonata models—have been the subject of recalls and class action lawsuits. However, Hyundai Motor America has refused to replace or repurchase the vehicle. Instead, they replaced the engine with one that now carries less warranty coverage than the original (12,000 miles vs. 26,000 miles remaining). Since the engine replacement, the vehicle has presented new problems, and now needs a new battery after sitting on the lot for so long. Hyundai has failed to offer meaningful support, leaving my family without a reliable vehicle for over two months. Hyundai has refused to replace or repurchase the vehicle, and I am now stuck with a car I cannot drive, cannot sell (due to the engine failure now reported on Carfax), and cannot rely on to safely transport my daughter. I believe this represents not only a serious safety risk, but also a pattern of negligence that could affect other drivers unaware of the risks. I respectfully request that NHTSA investigate this issue further and consider expanding oversight into Hyundai’s handling of these engine failures. I am a

The contact owns a 2017 Hyundai Sonata. The contact stated while the vehicle was stationary, the vehicle experienced an excessive oil consumption. The check engine warning light was illuminated. The contact stated that the vehicle required an additional quart of engine oil monthly. The vehicle was taken to the dealer, where it was diagnosed with excessive oil consumption. The dealer determined that the engine needed to be replaced and the repair would be out-of-pocket. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the dealer for assistance. The failure mileage was approximately 93,000.

I am seeking a resolution to the concerning and potentially dangerous issues that I have experienced with my vehicle. I got it from Carvana Dec 2023 and only had it for a year, and I’ve only drove 19,000 miles on it before my engine cut off on me while on the highway. I was going 70 mph when the safety of my life was at risk. After, I tried to send it to the dealership, they let my car sit for a month before even looking at it, they couldn’t tell me because they let it die. My car was completely off. So i got no full diagnostic. I have personally endured the traumatic experience of my engine suffering catastrophic failure. Also, my vehicle was consuming oil at an alarming rate, necessitating frequent and costly refills. I would sometimes even go 500 miles before the due of an oil change and would be told that my oil is very low. I believe that these problems should not be considered normal wear and tear. The hybrid sonata 2017 had a engine recall and so should the sonata 2017 limited 2.4L.

My Hyundai Sonata sport had a Manufacturer defect causing oil consumption. When my engine starting having issues they replaced it for free. I got it back and the engine light came on so i called they ask me to bring it back and i did. They told me the code was a po326 powertrain control module or faulty knock sensor. They said the code was a history code and they cleared it out drove it and the light did not come back on. I picked it up drove it and the light came back on. I called they said bring back again and before it could get it back over there the transmission went into limp mode or safety mode. They said my transmission was gone and needed a a new one. $4385.44. I wasn't having any issues before the engine replacement. All other mechanics think something happened when the replaced the engine. I just dont want to be taken advantage of. Long Hyundai Chattanooga Tennessee.

The check engine light light is on now giving code p200a I was driving and the center console shut off and the engine died I had to pull over and start the car again it started but the check engine light light is on now for a p200a I’ve looked it up and everything I can find says there is a recall but my car isn’t in it so what can I do I don’t want to cause a fire or an accident because my car messed up o.

This is the third time after 3 “repairs” that I have had my car at the dealer in less than a year. Car went into “limp” mode while driving down the highway causing car to stall and not go over 20 mph. First time they said it was a technical update needing done. Second time said low battery power causing issue so I purchased $300 battery from dealer and now showing cylinder 4 misfire and recommend replacing spark plugs and oil combustion testing due to having to add 3 quarts of oil every 230 miles due to excessive oil consumption. Dealer said this will not fix the issue however so why would I pay to have it done if it won’t fix the issue. Luckily these three incidents of engine power loss hasn’t caused me to have an accident but what If in 3 months and my engine loses power without warning for the 4th time in a year it dies cause an accident. I have a case open with Hyundai but am getting nowhere. I feel like a measly engine replacement would cost less than it will cost if this causes a major accident soon.

Paint peeling on hood and roof

I was driving on highway when all of sudden my vehicle began to shake hard and lose power, every time I stepped on the accelerator the check engine light came on, this happened on [XXX] in Los Baños, CA. My safety was at risk as all other traffic was going past me including semi trucks as I was trying to find a safe place to pull over out of harms way, as I was doing this the car shut off completely before I could even pull over. I had to get the vehicle towed to my local dealership where they had it for almost 3 weeks now, only diagnostic I’ve had back was that it has 2 misfires, one in cylinder 2 and the other in cylinder 4, and that it has no compression in cylinder 2. They said it isn’t covered under warranty which I believe should be looked into as I could of been serious hurt or lost my life due to this issues. I’ve had the vehicle serviced up to date since I’ve owed it and also noticed high oil consumption, not sure if this led to engine failure? The final diagnosis from Hyandai dealer is that engine is no good anymore and need replacement but it’s not covered under warranty.

Unknown... I recently got an oil change and not even a week later my oil light came on. There's no leaks, I've been to midas several times and no leak was found. Was told to check to see if it had any recalls, my vin doesn't produce a recall but I know there's something wrong with my car.

My vehicle was purchased in 2018 and currently has 128,000 miles. I took it to the dealership because it was puttering and not holding pil. The dealership did some work on the vehicle. Furthermore, after that trip to the dealership, my car kept burning oil even after recent oil changes that I found myself constantly adding oil. I took it to another licensed mechanic who informed me after a tune up that my car is consistently burning oil. This was after I had a recent oil change. The engine is defective, hyundai knows they are defective and refuse to do anything about it.

When turning the steering wheel to the left, the steering wheel jerks and pulls to the left, gets stuck some and the jerk back into place when coming out a left turn or curve to balance steering wheel position. Searched for recall and took to Hyundai but they could not find anything. They say maybe purchase tires, rotate your tires and/or wheel alignment. I have done it all. They said they heard others say that but don't see a recall or know what would cause it. Went on Reddit, and others are having the same problem. Therefore, there is a problem this jerking issue.

Car has been burning oil since September of 2024. It’s burning 2 quarts of oil every 500 miles. The oil is burning out spark plugs and coils every 3 months. These engines need to be recall and Hyundai needs to be held accountable.

Engine does not reach normal operating temperature, possibly failed thermostat. Front window does not defrost properly and ices up while driving for 10 minutes after warming up for 15 minutes.

The contact owned a 2017 Hyundai Sonata. The contact stated while on travel, the contact stopped at a local gas station. The contact stated while the vehicle was parked and unoccupied, the contact was informed by the store attendant that the vehicle was on fire. The contact noticed the fire came from under the hood compartment and the vehicle was engulfed with flames. The contact stated an off-duty police officer and the store owner attempted to extinguish the fire with fire extinguishers, however, they were unsuccessful. The fire department was called, arrived on the scene, and extinguished the fire but the vehicle was already consumed by the fire. The vehicle and all properties in the vehicle were destroyed in the fire. The vehicle was towed to a local tow yard. The vehicle was condemned to total loss by the insurance company. A police report was filed. In addition, the contact stated that 75 miles before the fire occurrence, the vehicle was started, and the contact noticed white smoke exiting from under the hood compartment. The contact interpreted it to be frost from the start of the engine being cold. The dealer was made aware of the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000

Every few months my car’s engine struggles. It doesn’t start, or I have to try a few times. For whatever reason I need to get an oil change a lot more frequently than normal and I’ve been to the shop before and the shop tells me that my engine is recalled but it doesn’t say that on the website when I put my vin number in. Whenever the engine stops working again sometimes the AC doesn’t work and it almost put my dog’s life at risk once.

The contact is a death investigator calling on behalf of the owner of a 2017 Hyundai Sonata. The contact stated while he was driving at an undisclosed speed, another vehicle failed to yield causing the front of the vehicle to crash into the front end of another vehicle. The events leading to the crash were unknown. The air bags were deployed. The owner of the 2017 Hyundai Senata was pronounced deceased at the scene; the cause was presumed to have been caused by the wheel hub dislodging. The death investigator arrived at the scene and discovered the wheel hub in the back of the neck of the driver possibly leading to the fatality. The other vehicle involved in the crash was able to drive off the scene. No further information was available on the other vehicle in the crash. A police report was filed. The vehicle was destroyed. The manufacturer was not notified of the failure. The failure mileage was unknown.

I keep having both my low beam headlight bulbs burning out and one of them started catching on fire. The driver side caught some type of electrical issue causing it to start smoking and eventually melted the connector and lightbulb housing

Experienced total loss of power steering when entering a parking lot. Was extremely hard to turn wheel to get into a parking spot. Red steering wheel icon with exclamation point was flashing on the dash. Shut off car, turned back on, and the light went off. Still had car towed, owner’s manual states to have it inspected by the manufacturer, don’t drive. Of course, Walser Hyundai Service Center in Coon Rapids could not duplicate the issue - so nothing was done. A C1102 code was detected meaning low voltage, however, when checking the battery and alternator, both tested good. Was told that there are 4 different parts to the steering, each one being very expensive to repair. Also, my display has been going out intermittently for the last year. Possible voltage too? My display did NOT go out when the power steering went out. ??? Computer Issue Maybe ??? Car already has 3 Extended Coverage issues - Power Steering, Fuel Filter Assembly, and Engine Failure, not to forget the excessive oil consumption problem (1-2 quarts per week). No recalls, just wait to see if it happens to you. Some of these issue are extremely dangerous, there should be recalls!!! They need to be fixed. I am now fearful to drive this car, it’s either going to kill me or someone else, especially if I lose the power steering at high speeds. Lost complete faith in Hyundai as a vehicle manufacturer, they do not stand behind their product.

I am filing this complaint regarding a significant safety concern with my 2017 Hyundai Sonata. Since around 65,000 miles, my vehicle has experienced excessive engine oil consumption. The issue has progressively worsened, and my car now has 126,000 miles. Despite undergoing an oil consumption test that confirmed the rapid depletion of oil, Hyundai and their dealerships have failed to provide a resolution. This defect requires me to add oil approximately every two weeks. The excessive oil consumption poses a potential safety hazard, as the engine could seize unexpectedly while driving due to insufficient oil levels. The risk of engine failure is further exacerbated by the lack of sufficient warnings from Hyundai regarding this known issue. This situation not only jeopardizes the safety of myself and my passengers but also other drivers on the road. I am requesting that the NHTSA investigate this matter, as it appears to be a widespread issue among Hyundai vehicles. Prompt action is necessary to ensure consumer safety and hold the manufacturer accountable for addressing this defect. Thank you for your attention to this serious matter. I am happy to provide additional details or documentation upon request.

The car's paint is peeling all over. The roof was repainted in 2018, the hood and side door in 2024 and now the the roof supports on each side and trunk are peeling . While driving a big piece of white paint flew to my windshield blocking the driver's view. It stuck under the wipers when used to remove it. Hyundai is aware and has recalled the paint but delays fix and then fixes in tiny areas so that you have to continue coming back for repainting. Now they do not want to pay for repairs stating the recall expired. It expired because of their delay and not painting the entire car. Hyundai should paint the entire car when there is a paint defect.

The makes a weird shutter noise when accelerating and won't crank over 60. Loses power when turning or when going uphill. Sometimes has problem starting. Enging light came on twice blinking, once I changed the battery it went off and was working fine. Now it's back on again after a few weeks. Plus my oil tank still comes on and I've just received and oil change. I just bought the car in August of this year, dealership sold to me with a faulty battery.

Driving home car just shut off still had power to steer and brake but no engine. Pulled it off the main road and it leaked oil but still no engine. Already had the dealer replace the intake manifold at my expense despite hyundai knowing the plastic lever inside fails. We were lucky the snowplow was going the opposite direction as the weather was horrible as we got closer to home. I have a dead car in my yard waiting to have a dealer look at it. We could have been killed due to fault of engine.

HEV battery constantly states that the car needs turned off. Hyundai had to replace my engine as it just died and blew a hole in a pipe

The contact owns a 2017 Hyundai Sonata. The contact stated while driving at an undisclosed speed, the vehicle stalled with the check engine warning light illuminated. Additionally, there was white smoke coming from the engine compartment and the exhaust. The contact retrieved DTC code: P0420 for spark plug failure. The spark plugs were replaced; however, the failure reoccurred. The vehicle was diagnosed with spark plugs and catalytic converter failure. The spark plugs were replaced. The contact stated that the spark plugs looked burned. The vehicle was taken to an independent mechanic where the catalytic converter was replaced; however, the failure reoccurred. The contact stated that the vehicle had been consuming an excessive amount of engine oil for almost two years. The contact stated that engine oil was added every 600 miles of driving. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The dealer was made aware of the failure and provided the contact with the cost for a diagnostic test. The contact declined to pay for a diagnostic test. The manufacturer was made aware of the failure and a case was filed. The failure mileage was unknown.

The engine started knocking while I was driving around a lot of cars and while I was going to AutoZone to see why the check engine light was flashing on my car wouldn't accelerate and randomly started stopping and I was fearing for my life when I was going on the highway to go back home. For almost a year now I noticed the oil in my car started burning more and more like I would only drive 1k miles and it would already be done with, so I had to replace it. Hyundai knows this is a problem with this car because I called and asked them about the oil and told me specifically it's an engine problem once it starts knocking then you can come fix your car but want me to pay and fix the whole engine and work process.

My trunk will not unlatch and open. Trunk opening buttons are functional, however the trunk will not open
