My car was smoking from under the hood. I had it towed to the dealer. Service dept said valve cover. Picked car up 2 days later and less than 1/4 mile from dealer the car was smoking, I called service department was told it was normal. Stopped at red light, smoking intense, turned back to dealer. I lost my brakes, stopped by the grace of God. Passerby told me to get out, my car was on fire. 2 minutes later it was fully engulfed. Total loss.

I am 86 years old. I bought the car brand new so I am the original owner. I have kept the car perfectly maintained and garaged from the day I bought it. My wife is also 86. She and I are the only ones that drive the car. To date, it has 73,822 miles on it. The main issue I am having is random, unpredictable stalling and hesitation when trying to accelerate. We have also had unintended acceleration. This always happens at the worst times which causes grave concern for our safety. We have taken the care to the dealership here in Cape Girardeau, MO called Chris Auffenberg Hyundai. They've charged me $130 only to tell me nothing is wrong. I have continued to try to work with them and they now have decided a new fuel pump will fix this which is $730. I have noticed there are already hundreds of complaints on the 2015 that all say they have the same exact issues I am having but this dealership doesn't seem to care. Here is what I have read. "The most common issue in the 2015 Sonata lies with its faulty throttle control system, which can cause stalling, hesitation, and even unintended acceleration. Currently, there is no fix from Hyundai." My dealership will not acknowledge this even though it is public information. I feel like they are going to keep replacing parts and are taking advantage of me. Darren Pruitt is the Service Manager at this dealership and I am not happy how he is handling this. Please let me know if there is any additional information I can provide.

The panoramic sunroof wind deflector is off I seen online there was a recall about that. I call hyundai customer service about it they said it's been fix already in 2016. I'm a new owner and not sure where the work was done before I got it, but it came unglued again. I purchased the car from John amato hyundai dealership and get the services done there because I'm under a forever warranty and can't going anywhere eles because of the warranty. Which nothing is done free on it and all the work I've had done from them I believe they don't do everything because it still rides and sounds the same and there #1 excuse is that's how hyundai cars sounds. So with that being said if John amato fixed it, I see why it failed again. Can check my car to see if recalls were really preformed and done correctly and what's needed now to be like new again.

While driving, received Hybrid system warning that shut the car down. Power steering and braking were non-existent so safely stopping and pulling over was near impossible.

My 2015 Hyundai Sonata has recently been having both electrical and engine problems. Roughly a month ago, I had my vehicle completely stall in the middle of the highway. I lost power and a bunch of lights came on at once. Thankfully, I was in the right lane so I was able to safely get off the road even though I had many other cars speeding around me. I had no acceleration, I was just cruising off the highway at this point. Thankfully, my brakes did still work. Engine light and a bunch of errors turned on but went away once I pulled off and restarted the vehicle. I pulled off the road and once I decided to try and start it and go again, my car felt like it had hardly any power the whole way home. Fast forward to last weekend, I was driving home and my car would not accelerate. The engine light comes on and this time, my acceleration didn-??t completely shut off, I was just very limited. I had to ease into the gas because I felt like it was having a hard time shifting gears and keeping up with the RPMS. I felt uncomfortable pushing it above 50. As I got close to home, I noticed a knocking noise in the engine. I plugged one of my code readers in and it spit out 7e8, 7e9 and I believe it was p1326. Super rough start and feels like it-??s going to break down if I try to drive it. I-??ve left it parked since

I am unsure what exactly happened but it is giving an error code for the engine sensor. I was driving the expressway (55-65MPH) and my car went directly into safe mode. Which I didn-??t kno what it was til later. I went from going expressway speed to almost getting t-boned getting off of the exit ramp as I was unable to accelerate over 2RPMs. So my acceleration would jolt my car when going over 2RPMs. I made it to a gas station where I had my mechanic friend meet me. He said I had no oil. We put 4 quarts in and it barely did the job! I had gotten my car serviced and oil changed not too far from when my car began to -??shut down-??. So oil is in the compartment, the engine light turns off. Well then I-??m driving the expressway AGAIN thinking the problem is solved but also curious WHY and HOW I had no oil. All of a sudden the car goes back into the mode. Engine light comes on an I am once again going de-accelerating in traffic on an expressway. I get off an exit and make it home in back roads. I had to pay for rentals and I was unable to get it to the Hyundai manufacturer. I got it to another certified mechanic which stated there is an oil leak somewhere but is unable to be found. As the 4qts added days prior, was almost gone again. The engine sounds awful, there-??s rattling noises, noises sounding like a fan is broken but still spinning. There was absolutely NO warning signs prior. Nothing was on, nothing was off, absolutely NOTHING to forewarn me of this awful situation until it decided it was going to safe mode on the expressway out of nowhere. I owe thousands of dollars in rentals, I can-??t afford to even pay that off! For Hyundai to diagnose my car, they wanna charge 80$! When I already have the error code from the previous mechanic. I don-??t have the money to be doing this funny business. The car actually turned off when I was driving it and was in like an idle mode or something. I have no clue. Nobody has any idea where the oil goes. It isn-??t showing smoke anywhere

2015 Hybrid Sonata, milages at 82,000 km, owned for 8 years. "Hybrid system warning, do not drive" message occurred, car lost 100% of its power, went into complete stop without any warnings on the middle of the highway. Hazard lights do not work and unable to warn incoming traffic that the car has completely stalled in the highway. The car is unsafe to drive. Went to Hyundai (here in Canada) several times, being charged every time for diagnostic and repair works, been told that the issues were fixed via software update. Problem persists. There are compelling evidences from different car forums, websites and NHTSA own database (28 reports under Unknown, 22 reports under Electrical sys. categories...) on the hybrid system failure or/and 100% power lost lead to complete stalled car. Although all these reports did not site any injury, major or death events, NHTSA should compel Hyundai to take appropriate actions to render the car safe to drive for the public because if accidents should happened, it cannot be undone and will affect lives of people. The public relies on a governing body to represent us and hold the manufacturer responsable to ensure that their mkt released products are safe: to save lives, prevent injuries, reduce vehicle-related crashes.

Driving on a busy street the car suddenly started to show a Hibrid system warning safety stop and do not drive and then the car slowed down on traffic scary situation since it was a busy road then another car pulled up and two guys help get it out of the road since the car would not start again. Our safety was at risk on the middle of the road and could possibly caused an accident. The problem still persist I towed it to the dealer and paid for a diagnostic wich the dealer took a month to return the car back to me and they did two recalls but never performed a diagnostic on the car and instead they just called the tech line and gave me a $6000 estimate for a hi voltage battery replacement.

While driving on the 91 freeway in the Fasttrack lanes, this warning displayed on the dashboard: "Hybrid System Warning! Safely Stop and Do Not Drive." The Fasttrack lanes are on 91 freeway are cordoned off, so there is no way to get out for 10 miles. We had to continue driving, but the car started losing power after 2-3 miles and began stalling. It was an extremely dangerous situation. We were very fortunate to find a construction zone that allowed us to pull the car into a safe spot. Once the car was stopped, it would not start and had to be towed to the dealer (Cardinal Way Hyundai in Corona, CA) on May 8. The dealer ran diagnostics and sent the codes to Hyundai tech center. The tech center advised the dealer to update the system software. After updating the software the dealer returned the car to me on May 9. Previously, on Aug 17, 2020, I had the same warning light -??Hybrid System Warning!...-?? while driving on the highway. I was able to take an exit and park the car safely. I had to get it towed to the same dealer. The dealer reported that the diagnostic -??measured resistance at safety plug. Found open circuit. Replaced safety plug.-?? The car was fixed and returned to me on the same day. It is completely unacceptable to have a car shut down without any warning in the middle of the freeway. If we had stopped in the middle of the freeway, it would have resulted in a very bad accident and could have resulted in loss of life. The tow truck driver told us that he has towed many Hyundai or Kia hybrid cars with similar issues. This problem seems to be a systematic and Hyundai should be subject to recall these cars to fix this dangerous problem. Hyundai needs to make sure that the car owner is provided sufficient warning of any impending problems with the hybrid system. Furthermore, the onboard communication system in the Sonata hybrid is outdated and does not work, so no diagnostic reports are generated. Hyundai needs to provide free replacement of the comm system.

In September 2022, we noticed a noise coming from under the car hood. Sounded like a thump as we accelerated. We took it to the Hyundai-€™s service department and was told that they couldn-€™t hear anything or find a problem. They changed my oil. We continued to hear a noise but thought it wasn-€™t a concern. In February, a fairly new tire went flat and we returned to the Hyundai service department. I received a call later and was told that they could hear a noise and they checked, and my oil was extremely low. They topped it off and told me to return in a thousand miles to see if it was still burning oil. If it was burning significant oil at that point, they would seal it and begin the Hyundai oil consumption test. At about 600 miles, I could smell a strong plastic burning odor and we checked the dip stick and the oil was barely detectable. We called Hyundai and was told there was nothing they could do and we have to go the full thousand miles to determine if we qualify for the test. We are concerned are engine is going to stall, burn up or catch fire in our garage. They told us, we couldn-€™t get are car in to be looked at until the end of March. After doing some research, I am aware that there is a current class action lawsuit against Hyundai for this issue.

I have been keeping up with regular repairs and oil changes on my vehicle; so I was surprised when the oil light flashed once or twice in the past week, specifically when I took a turn tightly. The oil was low when I checked it so I added a quart and didn't think much of it except "I should get into a shop soon and have that checked out." Two days later, my RPMs red-lined past 6-7k and the car was revving up but was not accelerating at all. I pulled over and checked the engine again and without showing any kind of leaks (no spots in my driveway/parkingspot) the engine had consumed the oil I added and then some. Moreover, the problem with the engine revving up but not accelerating was not fixed when I added the oil. It could have been very dangerous if I were on the highway and was not able to accelerate for any reason that could put myself or my family at risk. Now, the car CAN reach speeds of 75+ miles per hour on the highway, but only after a LONG period of acceleration and seems to be burning oil VERY regularly. I've grown very concerned about catastrophic engine failure on the highway.

My 2015 Hyundai Sonata Sport 2.4L is burning through oil like crazy and has been for a while now and I had no Idea. I get oil changes like I am suppose to do per the sticker and miles. Recently I drove about 4 hours away from home and I smelled burning but I had just got my breaks done and a oil change so I assumed it was the breaks. I got back home and still smelled the smell took it to the shop and they told me it was bone dry with NO oil at all. I was not at my mileage from the sticker so it wasn't time for me to get another oil change. They then told me these cars burns oil like crazy but that was the fist time anyone told me this and I have never had this issue ( I've had the car since Jan 2020 with no issues) They put more oil in it and told me to come back when it reaches the mileage. I went back to get my oil change and once again it was BARE!!!!!! They did the oil change and 2 weeks later I started my car and white smoke came from the engine part under the hood through my exhaust pipe AND my VENTS!! It was so much smoke I was afraid a fire was going to start!!! I lost a day at work and my daughter missed a day at school. Turns out I have a oil leak and I need my Valve seal cover gasket replaced. Not once did my oil light come on and TWICE my car had been completely out of oil! I am going to get my engine checked because who knows if it has done any damage (hopefully none). My car has never overheated or my check engine light has never came on. I see there a recall for this exact situation but the years covered was from 2008 or something until 2014 and I have a 2015! This is clearly a ongoing problem with Hyundai and something needs to be done. This is not a sweep under the rug issue. Its literally ruining peoples cars and we are left to fend for ourselves. Something or someone needs to advocate for the customer because the company clearly is not listening to complaints.
