2015 Hyundai Sonata complaints

While driving in city traffic, 45 mph zone, my car suddenly lost power, engine RPMs dropped, engine off, power steering impaired, I had to drift into turnout and assess. Car restarted, and I could drive, but RPMs would not exceed 1700, car wouldn't shift gears, speed would not exceed about 15 mph. No engine warning lights, no oil pressure indicator, no excess heat. I found I could drive at low rpms and manually shift gears to increase speed. I got the car to the local Hyundai dealer (Taylor hyundai, Augusta GA) and it has been there 8 weeks. They are telling me the engine has failed because I failed to change the oil for 14 months. They said my oil pan was empty. They asked me for maintenance records and said they were inadequate, and the engine needs to be replaced, may cost $6000 or more, warranty invalid. The car has 56,000 miles. Safety was put at risk due to sudden loss of power in busy traffic. Driving the disabled vehicle was risky to surrounding traffic, as the car could not maneuver quickly. I have read about similar failures with Hyundai Sonata vehicles, and a class action suit settled for 2011 to 2014 model vehicles. My car is still in the shop, unrepaired. I had to buy another used car in the meantime.

The contact owns a 2015 Hyundai Sonata. The contact stated that while driving at various speeds, the steering wheel would suddenly become extremely difficult to turn in either direction. During the failure, the steering fault warning light was illuminated. After turning off and restarting the vehicle, the vehicle operated as intended. The vehicle was taken to the local dealer who was unable to duplicate the failure; no service was performed. The manufacturer was notified of the failure but no assistance was offered. The VIN was not available. The failure mileage was 80,000.

Oil consumption, engine locked

We have had some issues but take very good care of the car maintenance wise. The car went into limp mode and we took it in they ran it and came up as the knock sensor.. I noticed there was a huge recall for these cars. What can I do? It has 140000 miles and again we keep up on the car. Is this something I need to seek counsel for? Thank you for your time. I look forward to hearing from you, Dominique

The contact owned a 2015 Hyundai Sonata. The contact stated that while driving at approximately 60 mph, the vehicle decelerated independently while the check engine warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the sparks plug and the PCV valve needed to be replaced. The vehicle was repaired however, the vehicle check engine light recurred. The vehicle was taken to the dealer where it was diagnosed but the failure was undetermined. The vehicle was taken to another dealer St. Charles Hyundai where it was diagnosed but the check engine light continuously illuminated. In addition, the contact mentioned while driving, there was a pop noise and noticed white smoke was coming from underneath the vehicle. The contact pulled over to the side and exit the vehicle. The fire department extinguished the fire. A police report was filed. The vehicle was towed to the tow lot and was destroyed. The dealer was not contacted. The manufacturer was not notified of the failure. The approximate failure mileage was 143,000.

This vehicle is consuming large amounts of oil. Up to 3 quarts and 1,000 miles causing the oil light to come on. Hyundai did an oil consumption test with failing results. Due to this they did a deep combustion chamber cleaning. The car still continues to burn excessive amounts of oil. I am told that this does not qualify for the class action lawsuit because it is piston related and not rod bearing related. There is a burning smell coming from the vehicle that does not smell like burning oil. I am highly concerned that the vehicle is going to catch on fire yet Hyundai refuses to do anything about it.

While sitting at a stop light the vehicle suddenly would not accelerate and would not rev the engine above approximately 2000 rpm. Then the check engine light began to flash. I was nearly rear ended because the vehicle just would not accelerate.

I had a safety recall on my car for the Smart Junction Box. I took the car to the dealership on March 9th 2022. They updated the software that controlls the Smart Juntion Box. On March 11th 2022 at 6:45am I got in a car accident due to the automatic braking system failure. I run into a Ford F-150 at the stop light. Even the brakes at this point failed to work properly as well. I called the deslership and explained what happened to me and I was told by the technician that there is a possibility that the update of the software that runs the Smart Junction Box has impacted the Smart Cruize Control. He said there is a possibility that the Smart Cruize Control settings have been erased to default so the car needed a new settings. That was something I did not know about. My car has the option where you can choose what distance you want between your car and the car in fromt of you. It goes from one-space car to four-space cars. So according to the technician this may has been the problem.

The contact owns a 2015 Hyundai Sonata. The contact stated while driving at 45 MPH and approaching a stop sign, the vehicle started shuddering and stalled. The contact noticed smoke coming out of the hood of the vehicle. There were several unknown warning lights illuminated. The contact was unable to restart the vehicle after several attempts. The contact was able to push the vehicle to the side of the road with the assistance of a bystander. The vehicle was towed to an independent mechanic who informed the contact to take the vehicle to the dealer for repair. The vehicle was then towed to the dealer where it was diagnosed that the engine had failed and needed to be replaced. The dealer sent a claim with diagnostic report to the manufacturer ; however, the manufacturer declined to cover the repair. The contact followed up with the manufacturer and was informed that they could not assist as she failed to complete an unknown software update, under Service Campaign Number: 553, designed to report vehicle imbalances prior to the engine failure. The vehicle was not repaired. The failure mileage was approximately 142,000.

The check engine light intermittently comes on, when on the car will stall when trying to accelerate, often accelerate when not intended, and runs rough. A second issue seems to be with the ABS system. On several occasions the ABS systems seems to engage and will not allow you to use the breaks (almost leading to several rear end collisions).

“Hybrid System Warning” 2 years ago last fall I was out of town & received the above warning - car would not start - car had to be towed - cost was over $500 - repair was a battery - paid out of pocket I believe but all this can be pulled from dealership on memorial in tulsa ok Last fall same thing happened - car would not start with same warning light - towed again & besides being out the tow bill all was repaired I keep getting this alarm that randomly flashes on my screen since last oil change (I asked dealership to research reason for alarm & they found nothing) while driving. I dont want to get stranded again & just want it fixed!!!! I have no where else to turn but to submit a report to hopefully get someone to research this for me. If you need documentation I can get something printed from dealership.

The contact owns a 2015 Hyundai Sonata. The contact stated that while either at a complete stop or while driving under 25 MPH, the vehicle would shake with the check engine warning light illuminated. The contact also stated that the vehicle would intermittently lose motive power while driving at highway speeds. The contact stated that the battery and oil warning lights would be illuminated. The contact took the vehicle to an independent mechanic where the mechanic discovered a misfire in cylinder # 4, as well as damage to the cylinder head. The vehicle was diagnosed with engine failure. Neither the dealer nor the manufacturer had been notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 105,000.

My engine is seized. Driving down the road normal all the sudden driving 14mph peddle all the way down to the floor. Mph slowly decreasing until it get to a complete stop and dies. The car turns on but does not crank. Check engine light is now on battery light, oil light and key fob light without warning. Did not have knocking ,shaking or stalling of the vehicle. Vehicle was diagnosed and towed twice.

This is a follow-up to former Complaint #11450586 (05-Feb-2022) and confirms that both my local Hyundai Dealer -and- Hyundai Corporation (USA) are aware of this diagnosable- and fixable problem—but they fail to issue a recall. In fact, a Service Advisor at my dealer expressly vocalized that 1) he himself [excluding his colleagues] has seen at least -2- of the same incident recently; and that 2) Hyundai Corporation (USA) issued a “(service) bulletin” about the problem. PROBLEM: The vehicle: 1) has a high idle; 2) shows a solid-illuminated CEL/emissions light; 3) severely resists braking—my vehicle would even slide through stop signs; 4) fails to “pick up” normally; and 5) drives unsteadily. This is at minimum and is my experience from both last week and from the original report on 05-Feb-2022. As explained to me today (28-Mar-2022) by my Service Advisor, there is a known fault with a component within the engine (Powertrain). Specifically, there is a tube that is—as I understand—meant to be FREE of fluids. However, and per the Bulletin, the tube becomes full or over-filled with oil from the engine (Powertrain). Further, the Advisor suspects that changes in temperatures (e.g., such as the teens *F back in Feb 2022) causes that oil/fluid to expand and contract, causing (further) damage. This issue must be remedied by Hyundai Corporation (USA) immediately because it is a *SAFETY RISK.* My Dealership emphasized severely how unsafe it would be to drive the vehicle off their premises

My car has been stalling, hesitating and sometimes I feel the engine shake when using the gas. I brought my car to the dealer to have the most recent recall fixed and asked them to diagnosed what else was going on with my car. They told me the stalling was just due to the recall. However, the very next day my car was acting up again. Additionally, the car at times will accelerate when I am not pressing on the gas. I don't think I need to go into detail about how my safety and the safety of others is compromised when you have a car that accelerates on its own. Lastly, there is no check engine light on. This has been ongoing for several weeks.

The contact owns a 2015 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the vehicle made an abnormal sound and was shaking while coming to a complete stop. Additionally, the vehicle was consuming an excessive amount of engine oil. The check engine warning light was illuminated. Upon inspection, the contact noticed there was no oil in the oil reservoir and refilled the engine oil. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer; however, the vehicle had previously had an oil change less than one month prior to the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 177,000.

I was driving the car and it basically shut down and wouldn’t accelerate and wouldn’t crank in the middle of a highway ! And don’t know what the problem could be the car will not start now

Car has been consuming an excessive amount of oil (1-2 quarts per week). While driving down the highway the oil pressure light came on and the engine started clicking and knocking. The engine died and all the dash lights came on. The car was coasted to the side of the road and towed into a local mechanic. The engine had seized and presumably dumped all the oil at the time of the engine failure since the engine had no oil when diagnostic was run. Car was taken to Hyundai dealership and is awaiting diagnostic and repair.

At low idle (stopping) car stalls out when stepping on gas. The RPMs run extremely high and very low at idle causing panic. The vehicle also stalled at full speed on highway but all electrical was still working. Car tends to sputter and jump while shifting.

Notice that my car has a leak or is burning oil. The dealership inspected my car and had the oil changed. Has not been a month and a half. Engine light came on. Checked the dipstick, and no oil. Second time this has happened.

Hello, the hood latch / wire / assembly on this make, model has an issue. It gets stuck during the colder months when trying to open the hood. After you pull the latch inside the car; you have to use your finger nails or sometimes a plastic item to pry the hood open and it works almost every time. During warmer weather, the hood opens normally after pulling the latch inside. This is a safety issue. I had and sold a 2016 Hyundai Sonata SE that had the same issue and a buddy of mine also with a 2015 Hyundai Sonata SE had the same problem. Many service technicians at Hyundai said it’s a known issue.

While going home on highway 95 at approximately 70 mph. The vehicle stalled almost causing many accidents. Thank goodness I steered it on the shoulder and it will not restart I had to call for a Tow. This was the 3rd time this happened. The first time was approximately a month in 2015 after my purchase it stalled on the highway. Again, in 2017 it once again stalled on the highway while I was driving. The dealership has told me on all 2 previous occasions that they had fixed the problem and it wasn't going to happen again. Here we are in 2022 and it stalled again. Why can't they just replace the engine? This is the second week and my car is still in the dealership which they are saying they don't know what the problem is smh.

Vehicle started making a front end noise when turning or hitting a bump.

I was driving with my 2year old grandson and my car stalled. My neighbors waving trying to alert me that my car was on fire.By the time I realized that the smoke began to come in through the vents. I had to use the key fobe to open the doors to hurry and remove my grandson from the car. The door's wouldn't open by pulling the handles. There were no warning lights or lamps messages or problems prior to the engine failure. The safety of my grandsons and my life were put to risk because of me not getting any notifications about recalls and defects.

The engine rattles and knocks and has stalled out multiple times, crossing traffic and stopping. The airbag light is illuminated on dash. When I’m driving the steering sticks in corners badly I’ve taken to Hyundai and they supposedly did an update to keep it from doing it but it’s still grabbing and sticking very dangerous.

The Pearl White paint on the roof has started peeling. This is a known Delamination issue from Hyundai and many other owners. It is beginning to peel in larger areas each week.

Excessive oil consumption-1-2 quarts per week Losing power almost comes to stop on highway-Dangerous Knocking noise at times from engine White smoke at times from tailpipe Rough high idling Code P1326 Code P0010 Hyundai is very aware these issues in their engines. Many complaints on Hyundai forms. Many articles written about these issues with their engines. Class action lawsuit against Hyundai about their engines. Hyundai corporate won’t help nor will the local service department at the dealer. All they want to say it’s out of warranty. Because the issue happened after 100000 mile warranty shouldn’t mean Hyundai shouldn’t fix the issue they are very aware of.

Steering Assist Problem Hyundai Sonata 2015 Sport 2.0T The car was purchased in Dec 2015 in California. We have had repeated occurrences of sudden power steering assist problems with the car, which typically happens after driving the car for 10-15 miles, and would go away after turning off the car for a few hours. The issue was first reported in Aug 2017 (case number 2017082505369). The power steering assist abruptly stopped functioning while driving, making it very difficult to steer, and a safety hazard (mileage 18,723). The dashboard had the steering wheel error light on. The dealer replaced the steering rack-gear+linkage. The same problem reoccurred in June 2020 (case number 2020043003513, mileage 46,915). The dealer ran diagnostics and again replaced the steering rack assembly. Between Aug 2021 to Feb 2022, the same problem has occurred again multiple times, and each time we left the car with the dealer to run diagnostics, they were unable to replicate the issue at their end, and refused to help us unless we brought in the car while the power steering assist problem existed, knowing fully well how unsafe it was to try and replicate such a dangerous problem while driving, putting our safety at risk! We raised the case with Hyundai, case number 18786891. Hyundai refused to acknowledge that there is a problem with the car and asked us to replicate and take it to the dealer for diagnosis. It has been very difficult for us to get any help from the dealer/Hyundai with the case

While driving on 395 in heavy traffic headed home I hit the accelerator and the car slowed down. The cars behind me almost hit me and swerved to prevent a accident pile up. I was horrified, shaking and crying because I knew I was about to be slammed from the rear. I hit the gas again and I heard a clinking noise. I knew I would not make it home. All of the lights in the dash came on. I pulled to a safe place (downtown near the Capital) and had it towed to the dealer. It was the first exit I could take. 3 weeks later, the dealer is saying it was an engine issue. My car is still covered under warranty but it appears as if they are trying to avoid replacing it. A rep called from the dealership asking about oil and I told him there was no warning lights that ever came on the dash to indicate anything was wrong; everything happened at once.

Car engine seized, my safety was at risk because the vehicle was unable to break and or accelerate while drifting over into traffic.Dealership has yet to inspect my car or any diagnostic test on vehicle at all . It’s been 2months . Engine light appeared 2 days before incident.

The vehicle's transmission seems to be slipping or something. As you begin to come to a stop, the vehicle bogs down and you can not accelerate. There is a long hesitation and then suddenly it kicks in and jars the car. This happens on a daily basis. The vehicle is also burning through oil at an unprecedented rate.

The contact owns a 2015 Hyundai Sonata. The contact stated that while her daughter was driving approximately 40 MPH, the engine seized. The contact was unsure whether any warning lights were illuminated. The vehicle was unable to restart. The vehicle was towed to the local dealer but was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 93,000.

On 1/12/22 I walked out to my car and saw that it was filled with smoke. When I opened the door I saw that the center console was on fire. I called 911. Very soon thereafter the car was engulfed in flames.

This 2015 Hyundai Sonata LTD ([XXX]) falsely indicates CEL/emissions light. When the vehicle is started and the temperature is appx. 20*F or lower, the indicator immediately displays. It is solid and does not blink. This happened on -3- days this week, over approximately 7 of -9- total ignitions in that time. Various forums show the same issue. Hyundai must recall this because it is either a false warning or else is a component within their control with which they failed to manufacture safely (thus contributing to the problem(s) and CEL). INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The contact owns a 2015 Hyundai Sonata. The contact stated while driving approximately 55 MPH, the vehicle inadvertently stalled.

The vehicle was towed to a local mechanic where it was diagnosed with needing the engine replaced however, the vehicle was not repaired. The vehicle was then towed to the local dealer. The manufacturer was not informed of the failure. The failure mileage was unavailable.

Sonata started having problems with less than 50,000 total miles. The accelerator is flawed and the vehicle cannot keep speed when traveling uphill or get to speed efficiently. The vehicle jerks for a few seconds when pressing the gas and the engine revs but the vehicle does not accelerate like it should. This has almost caused me to have accidents multiple times when pulling out into traffic. The check engine light came on when this started occurring and has been on ever since. I'm having the hyundai dealership take a look at the vehicle and see if there is anything that can be done.

The contact owns a 2015 Hyundai Sonata. The contact stated that the vehicle was consuming an excessive amount of oil. The contact stated that the vehicle consumed two quarts of oil per week. Additionally, the vehicle made abnormal sounds and had lost motive power while driving. The check engine warning illuminated. The vehicle was taken to the dealer. The dealer replaced the oil pan gasket and made other unknown repairs; however, the failure recurred. The vehicle was not repaired. The manufacturer was made aware of the failure.

The engine is burning over 5 quarts of oil between 600 and 1000 miles. The engine is the 2.4 litre and it is doing the same as the 2014 and previous model. It is also known that the 2016 has the same issue. Hyundai refuses to replace the motor or cover any cost. They are saying that the car is out of warranty when it has been in the shop for oil consumption pre-mileage but they said it was normal to be a quart or 2 low. Now the motor will be empty by 600 to 1000 miles. The dealers wants to put chemicals in the motor at a cost of 200 plus with now promise of resolving the issue. In addition it has been proven that these quick fixes are catastrophic and will cost more than an engine maybe a life in traffic.

The contact owns a 2015 Hyundai Sonata. The contact stated that while driving at a moderate rate of speed, the check engine warning light started flashing on the instrument panel. The vehicle then began to stall as the vehicle would not shift above the first gear. The contact was able to coast the vehicle to the nearest independent mechanic where he diagnosed the vehicle with engine failure. Despite the failure, the contact was able to drive the vehicle home. The contact then called several dealers in her area and each one informed her that there were no recalls on her vehicle. The contact then notified the manufacturer but received no assistance. The vehicle had yet to be repaired. The failure mileage was approximately 100,000.

Car fire. Car was brought in for service on a Saturday. Car started smoking on drive home. Called Hyundai and they said it was okay. Monday car was booked to be brought back to Hyundai because smoking wouldn’t stop and car caught fire. Incident 1/17/22. No inspection to date, no warning lights went off. Just smoke started and then flames.

215/55 R 17 My right rear tire has been losing air for at least 6 months. My tire pressure light is constantly on. I had my tire inspected and was told all 4 tires are compromised. The mechanic told me that my tires were wavy??? and that the tread inside my tires were damaged and I needed to replace all 4 tires. He also said my car would not pass inspection because of this defect in the tires. I feel my safety is at risk because of the inconsistent pressure that the tires may blow at any time.

Hyundai reprogramed their Theta engines to prevent an ongoing problem related to Theta engines not receiving oil to the crankshaft and connecting rod bearings. The software modification was done by an unknown software house. When I got the first notice, I asked both the local dealer, and the official Hyundai site if this software would cut power, potentially at the wrong time, like going up an entrance ramp. I got no response and I found out why. I tried entering a highway where traffic was at 75 mph. When I got onto the ramp the car was running fine. Suddenly the power just went away. I had the gas pedal all the way to the floor and watched the tachometer and speedometer go down rather than up. I pulled off at the next exit and switched the programming on my transmission to normal from econ mode. Up the ramp I went, and car started slowing down. Tried one more time using the sport mode and the power went away. I'm afraid to try and run on a freeway at rush our because of the lack of power. I think the needs to be a review of the software and see if changes can be made.

During weekend road trip, on the way back, engine has developed knocking noise, unusual vibrations, and loss of power. Car was able to make it home at low speeds with minimal acceleration. Oil check revealed that all of oil was burned up over a few days, as the oil check before the weekend trip showed full levels. Dealer would not even accept looking at the car for over a month, before their first available appointment. Independent mechanic confirmed engine knocking, burned up oil. They recommended engine replacement, but were not able to complete the job as the company would not make replacement parts available to them. Dealer has finally accepted car, also confirmed knocking noise and burned up oil. It would take another month for dealer to produce a repair quote -- $14,000 for engine replacement and additional 2 months of wait time for some parts to arrive -- much higher than what I understand it typically costs for a full engine replacement, but the dealer is left as the only option to charge however much they want, as independent services are blocked from acquiring needed parts. 87,000 mi in just over 6 years of use. No warning lights on the dash. No OBD status codes. All together this would add up to at least 5 months of inoperable car, and what looks to be a very inflated repair bill. Dealer is recommending a purchase of a new car from them instead.
