The vehicle concerned is a 2016 Hyundai Sonata Hybrid Limited. It originally presented a check engine and check oil light, and lost partial power traveling on the highway. This vehicle was able to return to its residence, and it was towed to a Hyundai Dealership. Photos and videos were taken of this vehicle prior to being towed, and its battery voltage was tested. The Hyundai Dealership initially reported a dead battery, and that diagnostics were completed. Further conversations took place to question if a jump box or battery charger had been used, and the manager offered to test this vehicle personally. The manager stated that two jump boxes started this vehicle, and then stated he drove this vehicle with two jump boxes connected. The manager insisted that this vehicle's issues were only caused by a failed (dead) battery. A new battery was purchased and then the Hyundai Dealership installed it. The mileage reported by the Hyundai Dealership on its invoice was 1 mile, yet the Hyundai Service Department stated that multiple test drives took place after battery was installed by them. The manager stated this car was fixed and safe enough that he would put a family member in it.

I purchased my '16 Sonata as a Certified Pre-Owned vehicle. It was 1 yr old, with roughly 36k mi on the odo. I bought it from Huntington Beach Hyundai, who showed me the Car Fax that it's CPO. They promised Hundai CPOs get what left on the 10 yr, 100k mi powertrain warranty. I've been doing oil changes per manufacturer recommendations since purchase. At roughly 40k to 60k on the odo, I noticed the car was burning a lot of engine oil. I brought my car to my local Hyundai service center, Tustin Hyundai, who told me 1 qt every 1k mi is normal. I thought it was a lot, but Tustin Hyundai told me there was nothing wrong with the car. Sometime after, I received mail about the Theta 2 engine recall to get the knock sensor install/update, and read about the risk of engine explosion/fire. I promptly got it done. Around this time, I read on Hyundai owner forums that excessive oil consumption is a precursor symptom to catastrophic engine failure. Sometime later, I noticed my car was burning a lot of oil, even more than before. I estimated at least 2 qts every 1k mi. I brought my car to Tustin Hyundai at roughly 75k mi on the odo. They started an oil consumption test, comprised of 3 oil level readings, each one every 1k mi. My car failed the first two. After the 2nd, my car stayed at Tustin Hyundai overnight to get a combustion chamber clean done. Tustin Hyundai told me doing so will solve the problem. Few months later, I noticed my engine was back to even more excessive oil consumption. I estimated at least 3~4 qts per 1k mi. I brought my car to Tustin Hyundai again, with roughly 80k mi on the odo. They said Hyundai corporate is rejecting all further service because my car isn't CPO, and that I ran out of powertrain warranty at 5 yr/60k mi. I called Huntington Beach Hyundai, who confirmed my car is CPO, and still has the 10/100 powertrain warranty. But Hyundai corporate, through 2~3 national case managers, told me I am out of powertrain warranty, and not covered.

Purchased the 2016 Sonata approximately four months ago. Was not told that Hyundai had a problem with the engine in this year and model. I have now learned that NHTSA is involved in this matter because there have been several engine fires. My car is rapidly burning through motor oil. While it is not smoking there is a light smell of burning oil. Reluctantly the dealership is promising to fix it but has yet taken steps to do so. FOREMOST, IS IT SAFE TO CONTINUE DRIVING THIS CAR? Further, can the engine be repaired or should it be replaced. A prompt response would be greatly appreciated!

My car is involved in the class action lawsuit because of engine failure and fire with my 2016 Hyandia Sonota. I have concerns with the above issue because of knocking in the engine and using 1 quart of oil every 400 miles. Hyandia extended the Power train settlement for life time. Yet, they denied to do anything about my car because or 98,700 milage. Dealer said only way Hyandia will do anything if the engine goes out. Hope it just goes out instead of catching fire.

I have been going to the dealership since July as my engine light was not shutting off. I kept being told that there were no loaner cars and that they could not fix the problems I was having kept putting a band aide on the issue and saying that I would have more problems. They told me the cat converter would need to be replaced but it was an engine recall issue. They had a loaner car for me for one day told me it was fine that it would probably go again I had them check the car again and they filled the oil and sent me on my way. Now I was on the side of the road with no car and am now being told they can-??t work on my car until March which since I have been seeing them for 4 months now for the same problem that just got worse you would think they would try to help me. Instead they told me to go somewhere else turn in my dead car or I have to tow it and then tow it back in March. I can-??t afford this right now it is terrible and there are no cars out there they are so expensive. Please help me I am very poor and have 2 jobs that require me to drive.

I was driving on the highway 11/30/2021 when my engine light came on and the vehicle was shaking uncontrollably and I couldn-??t accelerate much. I pulled over and called a relative to trail me to a local Firestone. I assumed it was spark plugs but they tested it and it was a code p 304 cylinder 4 misfire. My car is currently at a mechanic shop named forest hill garage in Montgomery Alabama they called me 12/8/2021 and told me it-??s a cylinder 4 misfire and it costs around $5,000 to fix and replace. He also stated there-??s 7 other vehicles the same type of Hyundai up there with the same exact issue!!! Something is definitely wrong and needs to be recalled. I haven-??t gotten the other documentation as of 12/08/2021 because I am at work

The vehicle consumes an excessive amount of oil causing the engine to stall out

- High Ridge , MO, USA

My engine has catastrophic damage due to not being notified by the manufacture about a recall that occurred years ago. Had I known about the recall, I would-??ve addressed it and prevented the engine failure. It is currently sitting at a Hyundai dealership as they are working with me to try to get Hyundai to cover the costs of the engine failure. So far, they refuse. My safety was put at risk due to the car stalling out on me at any given moment. I cannot and have not been able to safely drive this vehicle therefore, it has been sitting mostly unused as I continue to make payments on it over the last 6 months. This problem is a reoccurring issue with my vehicle and others and there is a class action lawsuit against Hyundai for it, in which I missed the deadline because I just recently became aware of this. The vehicle has been inspected by a dealer and was noted as -??catastrophic engine damage-?? needing a $7,000 new engine. The engine light first turned on about 6 months ago for me, but I was in the process of moving across the country that same week, so I put repairs on hold until I was settled in to my new area. Now that I have the time, and after the car had been sitting for 6 months, I took the car in to a dealer where they told me the bad news. It is worth also mentioning that this is the 2nd time I-??ve had damage done to my vehicle due to lack of recall notice. However, the 1st time my car was damaged, the dealer was able to fix the issue free of charge. This time around, they are needing to charge me $7,000 but are pushing that I get Hyundai to cover the costs due to the reoccurring issues with these recalled engines and their failures. I regularly maintained my vehicle and kept most of that documentation, so I know I did my part in taking care of my car. This is simply due to lack of recall notice that could-??ve prevented a large bill for myself and my car being out of commission and unsafe to operate without probable cause of an engine fire. Please help

Car unexpectedly stopped working and became disabled while trveling 40 - 50 mph on the freeway. Complete loss of power. Danger of a collision on the freeway. All dash lights and warning lights came on. Car would not shift and would not accelerate. It was unsafe to drive and could hardly move off the road. The first year I had the car the engine light came on and loss of power. I took it to the dealership immediately. Whenever I took the car to the dealer they said there were no codes and the car was was fine. The entire time I owned the car I would lose power on inclined roads and engine light would come on and off. Last week November 18 the car stalled and could not drive uphill again risk of a collision from the rear. I took the car to the dealer they said the car was fine. The dealership has never tried to fix the problem and claimed they could not duplicate the problem. Today 12/1/2021 the car stopped operating on the freeway completely and I had to tow it to the dealership. This car has been a safety hazard within the first year and Hyundai has done anything to address the problem.
