On 02/18/2023 at approximately 5pm, my family was driving on the highway, when unexpectedly, my check engine starts flashing and there is a noticeable decrease in acceleration and my vehicle feels rough/jerking as I head to the nearest exit. My spouse checks the vehicle and believes it is a spark plug/coil issue and we head to the nearest auto parts. The store rep is able to confirm engine misfire on all 4 cylinders, which does seem to indicate that spark plugs/coils should be replaced. We replace the plugs and coils, yet the replacement does not correct the problem. On 02/21/2023, I am able to have a certified mechanic diagnose my vehicle and he performs a compression test and confirms that 3 cylinders are at slightly lower PSI, and the 4th is at 0 PSI. Unknown to me, this means my engine needs to be replaced. The mechanic provides additional information that there are known issues with Hyundai engines and recommends I contact dealer, as he has also had a number of Hyundai owners with the same issue. I did further research and I discovered that my specific vehicle is not included in any current recalls. Yet I also discovered that there is an open Class Action lawsuit to expand the recall, which appears to include the engine in my vehicle. I did contact the Hyundai consumer affairs on 02/21/2023 and I am directed to contact my nearest Hyundai service center. I contacted the Hyundai dealership in Auburn, WA yet after my initial contact the representative fails to return my messages or follow-up. As this appears to be an ongoing issue with certain Hyundai vehicles, I want to make sure that there is a record of this incident for your review. The one ongoing issue I can confirm is that my vehicle appeared to burn oil. Although, it was inconvenient, I was able to get top offs at Jiffy Lube.

While driving on the interstate, car decelerated and would not go past 5 MPH. Had to get it towed. Throttle body replaced and now needs the the catalyt converter replaced in which I do not have the funds. There is an ongoing "ticking/clicking" sound in the engine, check engine light is currently on. While driving and coming to a red light, the car engine revved and the car started accelerating even though my foot was firmly on the brake. Car made a jerking move so I threw the gear into n and then park to stop the revving. Car is currently parked

I have previously reported this. My 2012 hyundai accent with automatic transmission often surges. On the highway, it will continue at same speed or even accelerate when I lift my foot. Stopped in traffic, it will lurch forward when the car ahead of me moves and I lift my foot. When parking, it will red-line when I shift to neutral or park. This does not happen all the time, but happens throughout certain trips, from when I begin to drive, until I exit the car. I have been to the dealer for evaluation, they say there are no codes, so it didn't happen. Apparently it did not occur during their test drive. This is a chronic problem and has been going on for a couple of months. When car tries to run away, I turn off the key. Will that remedy continue to work?

Throughout november 2019, my 2012 hyundai accent hatchback with automatic transmission( VIN [xxx] ) has been experiencing unintended acceleration. I have taken it to a mechanic who cleaned everything between gas pedal and computer, and the problem ameliorated for a week or so. Now the problem is back. In normal driving, lifting my foot off the accelerator sometimes slows the vehicle and other times it maintains speed or accelerates. (this is without cruise control engaged). When stopped in traffic, it will lurch forward when brake is released. When parking it often red-lines as soon as [ut into neutral. So far my remedy has been to turn the key off. However, my wife is now too frightened to ride in the car. I see all the other complaints of unintended acceleration in your database. How many deaths will it take for you to wake up to a serious defect? Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

While driving my car one morning I hit a patch of ice going 35mph in a 40mph zone. Upon hitting the ice my car swerved and I overcorrected, causing the car to jerk off of the road and flip onto its top, all while taking out a telephone pole in the process. Thankfully no one was injured and there was no property damage other than the car and telephone pole. However, not a single airbag in the 2014 hyundai accent deployed during the accident. Every single one was intact when the car ceased motion. Again, I took out a telephone pole, so I expect that my airbags would have been there to buffer had I been jerked forward or sideways. To my understanding airbags deploy generally between 16 and 30 MPH so I find it odd that they did not.
