I was driving to work as I normally would from the University I attend. About half way to my destination the check engine light illuminated and right when I was about to find a safe place to stop the car abruptly stopped in the middle of the Highway and stalled on one of the most dangerous highways in the U.S. being US I-20. I almost immediately got hit from behind however a few vehicles behind me did get involved into an accident due to the my car stopping abruptly with little warning. I called hyundai immediately and asked for a tow driver however the wait time was excessive and I had to go to work. I was able to start the car after 20 minutes, but it was in limp mode and I pulled off to the side of the road and had to uber to work. The next day I had got a tow truck to pick up my car and take it to the dealership where they said the car had accidentally triggered the knock sensor by mistake and replaced it free of charge. However the very next day it happened again after driving about 30 miles. And I took it back to the dealer they offered the same thing a replacement sensor. When I did some research and the car actually needed a new Engine after a recall had been placed. Hyundai refused to replace the engine after the knock sensor deployed. This is Hyundai's issue and it needs to be addressed. I was forced to put the car on the side of my house for the time being and get a rental until I could afford another vehicle. This is very disappointing from a consumers point of view. I filed with the extended warranty campaign TXXC and got denied due to the amount of miles on the vehicle. However there was no warning before the engine failed. The car was very well maintained and had regular Oil changes with full synthetic oil every 5k miles. No precursors to the engine failing occurred, like a knocking or jerking or anything. This is an issue that hyundai need to address. I am very disappointed. Campaign reference number for my case 17507525.

I have been receiving a 'safety stop. Check hybrid system' warning multiple times. I have taken it to Hyundai multiple times telling them of the issue. They kept telling me no issue could be found. The last instance they updated the software in the car in what appears to be a hail mary to say they did something. Last night I was traveling I was traveling on the highway at about 60 mph. The car started dinging and gave me the warning error attached. The car completely lost power and only allowed me to coast. I was lucky enough to barely able to get myself into a location of relative safety. I parked the car and restarted it and was able to drive once again. This continues to be an issue, extremely unsafe, and Hyundai cannot give me an explanation or fix the problem. This is unacceptable and almost lead to a massive accident.

The vehicle was in motion. I heard a noise under the hood. It got louder when I would let go of the gas pedal. I took it to the Hyundai dealership on thorton road in lithia springs, ga. It's taking 4-6 weeks just to complete the bearings test. The dealership has no available temporary vehicles, because apparently several other owners are in for the same issue. This is an inconvenience, I'll still be making payments on a vehicle that is parked. When I called the dealership for a rough estimate for trade in, they told me 1K since it needs a new motor.

I had my oil changed 2 days ago. I drove to work the next day with no issues. When I was driving home I heard a noise and my RPM meter was flickering. My car had stopped in middle of street. Once I was able to get safely to the side of the road I inspected my engine and saw there was a hole the size of 50 cent coin. In the engine. I am not sure how this happened. As I just bought the car, 5 months ago.

My car cut off on a city street, on 4-11-21 and when I cut it back on the check engine light came on and was blinking with the acceleration reduced and the car was jerking. I got the code P1326 from a local auto store and upon doing research, I discovered there's an open recall for this specific code. I scheduled the appointment with bob mayberry Hyundai, and had the car towed to the dealership in monroe, nc. I called for an update and was told that they were waiting on the corporate office to approve the next steps and that the same code P1326 popped up. I called the corporate office on Wednesday morning after getting nowhere with the dealership and was called shortly after stating that the car was ready for pick up followed by some things that needed to be repaired. They cleared the code with a system update but when I got the car back it was still giving acceleration issues, I called and reported the issue to the Hyundai corporate office and was advised to take the car to another dealership and they would work out the details. I scheduled my appointment with the Hyundai of lake norman, nc for today 4-19-21 and was advised the car passed the tests that they ran and again was provided a list of recommendations of repairs. I got the car back and now the acceleration issues still is ongoing especially if I am stopped and take off but now if I drive over 50mph the car is shaking. I had my brake pads replaced and paid for the oil leak last week. This is the second dealership that put me put me back in the car with known issues. I feel like they're going to have me pay for everything before the car is repaired and now I am in fear that if car shuts off again, myself but my children could be injured.

Engine had a critical engine failure, per dashboard?,while driving on highway, no engine warning ⚠️ lights before failure! car engine switched to low gear and immediately only drove about 10mph. I was able to move to slow lane then off to the shoulder...my car was not hit by any other car...but it did come close. Drove perfectly fine up to engine failure/seizure. This is an extremely unsafe condition for a car engine to be in suddenly. Again no oil or engine lights on before engine failure. Hyundai case has been created # 18049339 and dealer notified. Both appears to me not to understand the seriousness of this safety hazard... engine has been replaced by a certified mechanic after Hyundai refused to help with this matter. I will include response and invoice for engine.

Disappearing oil. For years now my car has been progressively using oil. Now I can't even go a week without putting in more oil and it has fouled spark plugs and left me stranded twice now, and continues to excessively consume oil. I finally got tired of this at 130K miles and took it to reliable Hyundai in springfield, mo. This dealership has been completely useless in offering any help, answers, or solutions. They've already charged me $400 for a 'combustion chamber cleaning' - told me I would be reimbursed if it didn't work, then when it was obvious it didn't work they did not refund me. They have made me jump through hoops in hopes I will eventually get a new engine, but repeatedly remind me ultimately that may not happen. In 2 months I have had to go to reliable Hyundai, missing work, 11 times for their oil consumption test when it's obvious nothing is going to change because 'that's Hyundai's protocol. I am going to lose my job for attendance and even after that, Hyundai still might not fix the issue. Horrible company, with horrible practices and customer service. Now I'm stuck with a car that has lost a tremendous amount of value, continues to devour oil, and Hyundai doesn't want to do anything about it until after I go there nearly 15 times. Unacceptable. When I bought my car I didn't get a 'it'll prolly only make it to 140K miles' discount. Force Hyundai to recall all of their faulty engines for oil consumption as well! if I wasn't so diligent my engine would have seized by now. I shouldn't be punished for making sure my vehicle is properly maintained.

My check engine light turned on and my car has power hesitation during acceleration. This happend 1-2 days out of the week until the forth time it happened the check engine light stayed on and continues to have power hesitation as well as high idling at all times, burning oil, smoke coming from the exhaust, and the brakes are extremely hard when needing to brake. I took it to a local mechanic and they did a diagnostic that returned a code of P0010 and they referred me to a Hyundai dealership for repair. I was also given a technical service bulletin with a campaign number of 15-01-022-1. I took it to the dealership and they also came back with the same code. I have paid for the parts and diagnostic and they couldn't give an estimate of when the parts would be available because they are on back order. Here I am two weeks later calling the dealership to follow up and was told by the parts department that they contacted Hyundai directly and there are 1800 of those parts on back order with an estimated time of being at least two months for the parts to come in. Hyundai also stated that they have submitted a high priority for them. I will be without a vehicle for who knows how long.

While driving on the highway, my engine abruptly died with all subsequent warning lights coming on. I had no power, beyond battery power, and was stuck on the side of the highway for 2.5 hours during rush hour. Engine would not restart or turnover representing a likely catastrophic engine failure. My local Hyundai dealer did not seem surprised by this revelation and they still wont tell me what's wrong even though the car has been un their possession for 72 hours.

The connecting-rod bearings in the engine wore out prematurely. My car only has 75,000 miles on it and does not come up on a VIN search at Hyundai as a recall vehicle even though it has the 1.6 gamma motor in it. The description from Hyundai of the issue is the following, "abnormal knocking noises from the engine, reduced power or hesitation, illumination of the "check engine" light or the engine oil-pressure warning light; or a burning smell, oil leaks, or smoke." This is exactly what happened to us when the car died. We took it immediately to our local mechanic who was shocked at how worn the bearing wear and the large amount of metal shavings in the oil.
