2015 Hyundai Sonata complaints

I have been driving at night about 3 times now and my headlights have gone off on their own and come back on after about 10 seconds. This has happened on countless other Hyundai drivers vehicles and needs to be investigated.

My vehicle has an oil consumption problem despite the fact that my car has been excluded from the class action lawsuit. I’ve had it in the shop and they have confirmed the oil consumption issues. There are countless other vehicles excluded from the class action lawsuit that have the same theta engine as the other vehicles that were included in the lawsuit. This needs to be investigated. I still owe over 6k on my car and it’s one trip away from being completely undriveable

The contact's husband owns a 2015 Hyundai Sonata. The contact stated while the vehicle was at an independent mechanic for an oil change, the contact was informed that the vehicle was experiencing excessive oil consumption and that it was a known failure. Additionally, the contact stated while driving 73-74 MPH, the vehicle shuddered and stalled. The contact was able to pull to the side of the road. The vehicle failed to restart and was towed to an independent mechanic, where it was diagnosed that the rod bearing had caused engine failure. The dealer determined that the engine needed to be replaced. The mechanic informed the contact the failure was due to a factory defect and would reoccur even after the engine replacement. The vehicle was taken to the dealer, where the same assessment was made. The dealer filed a claim with the manufacturer and sent a diagnostic report with pictures of the failure; however, the manufacturer denied the claim several times. The contact stated that the engine was previously replaced. The manufacturer was notified of the failure. The failure mileage was approximately 152,550.

Was driving on the access road... Luckily .... When I lost all power. Turned off my car and wouldn't restart. Had it towed , 1 month later and $7500 had to get a rebuilt engine. Which now I'm having 100s of issues. Love my car but this is literally stressing me out. Bought the car 2 months before this all happened

I purchased a 2015 Hyundai Sonata. Two years ago, I'm having issues with my car paint peeling off in the hood, roof and trunk. Many times I when to the dealer to ask them about the recall, and they state that there is nothing they can do since they did not have anything registered for a paint peeling recall. My car day by day is getting worse and I need help for this issue to be fix.

Vehicle has manufacturer defect paint started to peel

My 2015 Hyundai Sonata with Quartz White Pearl paint continues to peel off my car and cause me to swerve thinking that there is something coming at my car like a bird due to the paint peeling so fast. This is also a concern for drivers behind me as my roof pain is peeling and may fly into their line of sight/vision which could potentially cause an accident.

I was driving on the highway and my engine violently started to shake and I pulled onto the shoulder and the engine shut off. I’ve had oil leak and engine problems with this car for 2 and a half out of 3 years! I’ve had to buy countless gallons of oil. Multiple spark plugs, coil packs, etc. You can’t drive the car for one whole minute without it stalling in traffic and almost causing accidents. So I can’t drive it!

The contact owns a 2015 Hyundai Sonata. The contact stated while depressing the brake pedal, the vehicle veered to the right. The vehicle was taken to the local dealer and the brake rotors were modified, and the failure was corrected.

The cause of the failure was not yet determined, and the vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 70,000.

No check engine light was on. Heat cold gage was normal. No lights indicated what so ever. Engine started knocking really loud turned off while driving 70 mph on the freeway when it turned back on wouldn’t go past 20 mph. when accelerating knocking would increase. Wouldn’t accelerate past 20 mph. Took my vehicle to my local Hyundai dealer to be assed and they told me about the 953 campaign recall. I knew nothing about. I am 4th owner to the car from a used local dealership. My local hyundai refused to replace engine as well as corporate due to 953 campaign not being installed prior to engine failure. I only had the car a year and half and engine always sounded abnormally loud. I did tell the dealership this when we purchased the car as well as a few times throughout the time we went to make payments in person and they said it was normal Hyundais have loud engines. ultimately engine turned off while driving 20 mph and failed to turn back on at all. Out of a car since July 3 2024. No rental car was provided to me and had to pay for the diagnostics fee of $195 that was suppose to be waved once claim was approved but due to the 953 campaign not being installed by any of the previous owners or dealership my claims were denied! Now Hyundai wants $9,000 to replace engine with new belts and labor together! I don’t even have that kind of money at all!! RIDICULOUS!!

Steering wheel locked with skid slip lines and red steering wheel and exclamation mark lights on. Steering wheel locked up while driving. The car will no turn and is not drivable because the wheel will not turn.

On June 30, 2024 I was driving a 2015 Hyundai Sonata and the car caught on fire. There were no warning lights/ dash indicators/ no check engine lights or other warnings present. I had just exited the highway and while sitting at a light, smoke began emanating from the hood and within seconds the smoke turned dark brown at the vents near the windshield. I immediately exited out of the vehicle. I did not have time to pull over out of traffic. The car was engulfed in flames within a very short period of time. I had only seconds to exit the car. I would have struggled to get any passengers out of the backseat safely (i.e. kids in car seats) had I not been the only one in the car at the time. We had notified Hyundai of engine concerns that began in 2023, and they had given us the runaround for many months requiring us to submit paperwork for oil changes for the lifetime of the car and to keep returning to the dealership for "testing" after driving a certain # of miles. They required us to bring the car in to have pictures of the engine taken to ensure there wasn't "neglect" to the car on our part. This excessive and lengthy process by Hyundai took several months after initial concerns were brought up with the dealer. After being required to submit voluminous amount of paperwork and several trips to the dealership for "testing", Hyundai finally agreed to replace the faulty engine. We were told we could continue to drive it until a new engine was ordered. The new engine was schedule

At 40,000 miles the transmission is already jerking, shifting hard into gear and downshifting hard .

My headlight and break lights constantly go out and need repairs and malfunction each time a change the light bulbs. My engine does not hold oil and it leaks constantly after 20 days of driving I have to get oil change every 30 days. I have repaired this leak on several times by the professionals and it still leaks and locks up my engine due to low oil.

While driving on the highway Emmy pearl white paint began chipping on my car flying up into my field of vision which not only was distracting while driving but appeared as if it came from another vehicle even though it as from my vehicle. Prior to pulling over to see what happened, I ended up trying to avoid this thing that flew into my field of vision out of no where when I realized it was my chipping paint. I have contacted Hyundai who states they aren’t liable for the damage as it is out of their paint warranty. If this issue doesn’t get resolved and these car companies aren’t held liable for their known mistake, then more accidents will occur in the future.

In April 2023, I purchased a 2015 Hyundai Sonata Eco from Carvana with 56,000 miles. By May 2023, the mileage was around 72,000. While driving from South Houston to North Houston on [XXX], 2023, the car loudly popped as I exited the highway around 5:00 pm CST. I noticed smoke coming from the rear and parked in a construction zone near a convenience store. Upon inspection, the vehicle stopped working, and I saw a significant fluid leak underneath. A bystander alerted me to flames from the bottom and under the hood. I called 911, and the fire department arrived to extinguish the fire. Fortunately, there were no injuries or property damage. I later discovered that specific 2011–2015 Hyundai models had been recalled due to fire risk (NHTSA ID: 23V-651000), but this did not include the Hyundai Sonata Eco. The recall was due to the anti-lock brake system (ABS) module leaking brake fluid internally, potentially causing an electrical short and leading to a fire. I have photos and videos documenting the incident. Following the incident, I filed a claim with Travelers Insurance, and on May 28th, 2023, the vehicle was declared a total loss. While I appreciate their offer of ~$13,000, it is insufficient to cover the remaining loan balance of approximately $17,300. I am worried about the financial impact and potential danger I face due to this malfunction. The lack of information highlights the need for better consumer education. I am now looking into options to cover the remaining loan b

Engine just stopped working. car stop running turned off in the middle of traffic in Dallas Tx. I took my car for an oil change the mechanic said he’s had plenty of 2015 sonata engines just give out and some catch a fire as well.It gave no warning and no smoke. This happened last week.

My 2015 Hyundai Sonata Sport with 63k miles does not show any open recalls relating to fires however, my car was parked, went to turn it on, smelled an electrical smell and white smoke began billowing out of the engine. Within minutes the vehical engine compartment was engulfed in flames. I was able to remove my family from the vehicle and fire department came out to extinguish the vehicle. Thankfully everyone movedthere vehicles and no other vehicles were impacted but insurance has inspected the vehicle and determined it's a total loss as the whole engine compartment is melted. If not for me thinking and the action of others, many others cars could have been burned and my family burned and injured as they are still shook up about. Hyundai offered me a low settlement but there is know recall on the specific VIN for electrical or engine issues. The following weekend I met a guy who just purchased a pre-owned Hyundai and after leaving he stopped at a red light and the vehicle engine compartment went up in flames while parked. There is a larger issue at hand here and please help us investigate this so no one else has to go through this nightmare.

UNKNOWN, car was driving fine on the highway, then all RPMS were lost and the car couldn't accelerate past 40mph. At the same time a loud knocking started and when i was able to park and pop the hood, the engine was clearly vibrating and the source of the knocking is undetermined. there are recall's for improperly welded rods in the 2013/14 model sonatas and the 2016 so i find it hard to believe that Hyundai doesn't know that this year and make would have the same known issue and those models have all had recalls already except for mine...

Recall notifications for Hyundai campaign 251 but no remedy available since early 2023. Finally learned a remedy was available, made online appointment with my dealership (Future Hyundai of Concord, Concord, CA) but when I arrived for my appointment, they said they did not have the part. That was April 29, 2024. I was told to follow up in a week, which I did. Part still not available. Followed up several more times to which I have not received any response. I am driving a potentially very dangerous car now awaiting this recall remedy. Last year I waited 5 months for a new Hybrid battery with similar lack of communication and delays.

I have had my car serviced twice by the Hyundai dealership for the same exact issue. I believe I was told it was a knock sensor. A refurbished engine ended up being put in. The car is still having the same issues as when I first got it serviced in 2021/2022. My car is sputtering, loses power when accelerating and stalling. My car has always had an oil consumption issue and is causing additional issues with spark plugs.

Seat Belts will not recoil. This is a very unsafe situation.

While driving our vehicle (Hyundai 2015 Sonata Hybrid) around 25 MPH speed in city road... the vehicle stopped completely by itself in few seconds. Got the message "Hybrid System Warning! Safely Stop and Do not Drive" in dashboard and beep beep sounds. Thank god, no accident, the vehicles behand able to stop and avoid the collision. This is serious SAFETY issue, as this could cause accidents if vehicle stops by itself while driving. This is 3rd time in last few years with this vehicles. The recent incident happened was on 5/1/2024 morning around 8.00 am. We went to the Hyundai Service Center and they did looked at the codes and ran some scans and they found nothing wrong. And they said it could be some wrong system warning and can be ignored, as they can't reproduce the issue. And told us to report if this happens, but the worry is that, if this happens it could be serious life threating accident or injuries. They said they also got similar other Sonata Hybrid got same issue reported same day, but they can't find root cause. Same issue was happened last on 9/30/2022 and one before in that same year. They can't find the root cause that time too. They just updated software that time...and hoped that will fix. But the issue repeated again. While searching on the internet, found many people reporting this same error message and suddenly stopping the vehicle by itself. Very scary safety concern. So that's why we are reporting this to NHTSA. To take action on this with the Hyundai

Drivers side seat belt does not retract properly. If i pull it out a little too far when buckling then it will just hang there instead of retracting snugly so it provides the same amount of safety as having no seat belt on at all. Every time that I took my car to the dealer for different fixes I always brought that up and they always overlooked it and never did fix it and now my extended warranty is out and it's still not fixed even though it was like that the day that I bought it and I started complaining about it that very first week.

My Sonata is experiencing Engine failure due to excessive and irregular oil consumption. The Hyundai dealership conducted an oil consumption test in which it was discovered that the car is excessively using oil. My Safety and the safety of others were put at risk as the engine slow and stalls without prior warning and the check engine light does not come on until the vehicle slows and stalls. The vehicle was inspected at a Hyundai dealership and submitted to Hyundai for all or partial financial assistance for a new Engine and in turn was declined by Hyundai even though they have a know issue of their Engines consuming an unusually high rate of oil.

White pearl paint is peeling on the hood, roof and trunk.

The check engine light began flashing so I shut the car off and had it towed to West Allis Hyundai. The service garage took the car for a test drive (even though the user manual states not to run the engine), and according to the dealer, the car engine "blew up" and stopped running. I assume the engine seized up. the engine only has 43,000 miles and should be covered by the 100,000, 10 year warranty that comes from the manufacturer. The car has been at the dealer for over a week without any definitive answer if the engine will be replaced by Hyundai under warranty. Also, the dealer has not provided a loaner car so I am without any transportation while my is in the shop. Note that since I've had the car all maintenance has been done by West Allis Hyundai.

Engine light comes on and alarm stating hybrid sytem failure unsafe to drive. Car loses power and can't be driven. Had this fixed twice. This time it only was fixed for two days.

In December, 2019 I purchased a 2015 Hyundai Sonata for my son that had around 32K miles. Maintenance records looked good, and I continued to keep up with the maintenance on this vehicle. Around 64K miles, I was notified after an oil change the vehicle was low on oil and a gasket needed replaced. I took the Sonata to another place to get the oil changed and for a 2nd opinion. The conclusion of the 2nd opinion was there was internal pressure causing excessive blow by. That even if I replaced the valve cover gasket, the pressure would build up. Ultimately, we determined the vehicle is consuming/burning oil. Columbia Hyundai said there wasn’t anything they could do because my vehicle was out of warranty. My issue was and continues to be Hyundai will not do anything about the oil consumption issue. I am being told the engine will fail and maybe then if a rod is thrown will they replace the engine. I am putting a 1 to 1.5 quarts of oil in this vehicle every two weeks. My son still drives this vehicle and he is in college. Hyundai wants my son to drive this vehicle until the engine fails until they will even consider doing anything about it? I don’t even trust this vehicle to take on long trips. It has been a problem trying to keep up with this issue. When the engine fails (Hyundai said it will) while my son is driving this vehicle, I pray he is not on a dark country road, or on the expressway. Hyundai's negligence and their willingness to ignore this issue is irresponsible. I can

The contact owns a 2015 Hyundai Sonata. The contact stated when starting the vehicle, the vehicle experienced a hard start and shuddered. No warning light was illuminated. The vehicle was taken to an unknown dealer, where washer fluid was poured into the vehicle. The vehicle was then taken to an independent mechanic, who informed the contact that the oil was 2 quarts low, and the mileage was below the next recommended oil change.

I had my engine replaced less than 5000 miles ago and now my check engine light is on once again causing more problems and Hyundai is very unwilling to do anything

Car repeatedly illuminates check engine light since my purchase on 9/30/2023. When this happens the car goes into limp mode, fails to accelarate and at times stalls. This has happened on the freeway and at busy intersections while driving.

WHITE PAINT PEELING OFF IN LARGE CHUNKS FROM ROOF

Check engine light illuminates repeatedly causing the car to go into limp mode (max speed of 30) & at times it stalls while driving. I purchased it on 9/30/23 & check engine warning light has illuminated 20+ since then. I’ve repaired and addressed all of the codes. It also occasionally accelerates abruptly when stopped causing the car in front of me to be hit from behind. In addition to all of the above safety issues, it also has an extremely high oil consumption rate. The engine is faulty and needs to be replaced.
