After an update for a recall for brake issues, the dealership updated the knock sensor update without my consent. After the knock sensor software was installed, my 2012 Hyundai veloster will not operate without going into protection mode. Hyundai states that they can not reverse the software update to make my vehicle operable again. This has already come up as a safety concern as my wife was on the interstate when the vehicle shut down in 70+ mph traffic.

Subject: Issue After ABS Recall Service on My 2012 Hyundai Veloster Dear [Hyundai Customer Service/Dealer Name], I recently took my 2012 Hyundai Veloster to the dealer for the ABS recall service, where they performed an ECM and ECU upgrade as part of the fix. However, immediately after the recall service, my car began experiencing a serious issue. The Check Engine light turned on, and now the car won’t accelerate past 4,000 RPM. This problem did not exist before the recall, and I believe it may be related to the update or service performed. I would appreciate it if you could look into this matter, as the issue started right after the recall work. Please advise on the next steps and whether this can be inspected and fixed at no cost. Thank you for your time and assistance. I look forward to your prompt response. Regard, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have issues with past recalls, but they are not showing up in this list. I had a Body Throttle recall and 5 minutes after it was fixed it broke down and then again a week after and a month after altogether until the body throttle had to be replaced. I had the knock sensor recall done and now it went off code P-1326 is showing with a check engine light and it only drives 62mph. I mean the engine is bad and may catch on fire, and need to be replaced. Yes, the dealer knows and is waiting for my car to be put on the engine replacement list, which has been over 4 months now. There is a lawsuit to change it but Hyundai is not doing it.

On 08/17/2022, we had to have the car towed to the dealer for a very concerning issue. My son was driving down a major highway (middle lane) and as he attempted to accelerate, the car was not responding. It was like the car went into neutral and the rpms went up, but there was absolutely no acceleration. It was scary as he had traffic all around him and needed to get over to the breakdown lane. He finally got over and the car would not move forward or reverse. The check engine light also came on, so we had the car towed once again to the dealer. Once there, they looked it over and said it needed a new MAP SENSOR. They also stated that they thought the problem was with the DCT CONTROL MODULE. They said that they needed to do a RETEST of the DCT CONTROL MODULE and followed through with that. When I went to pick up the vehicle, I was told that the car was working properly, but they couldn’t be sure that it wouldn’t happen again. If the same thing happened again then they would need to replace the DCT CONTROL MODULE. After paying $800 to have my car fixed, I didn’t feel very hopeful. It makes you pretty anxious to drive a car that just loses power out of nowhere. Under normal conditions, losing acceleration on a major highway could severely affect the driver’s ability to control the vehicle and maintain a safe speed in traffic. This could cause a major accident. Here we go again. On 09/23/2022, my son was driving down the highway when he suddenly lost power again. The same scenario played out once again, only this time he didn’t have much room to pull over. He was forced to pull over in an accident-prone area of 77 South with a cement barrier next to him. Soon, he saw police lights behind him. The police officer was very concerned with getting the car towed quickly and showed my son the skid marks on the pavement from a previous accident. Now the dealer is saying its the transmission and transmission control module. This car is very unsafe to drive.

Rolled backwards while parked in my driveway twice and vehicle was found out in the road by my neighbors. I was driving it a week ago and my RPM's were tacking really high but could not accelerate speed and I was in 6th gear and it was telling me to shift to 6th then 5th back and forth. Had it checked out at dealership and they said my clutch had abnormal wear and tear but wasn't covered under warranty. They did not check the parking break to see if it was what caused the malfunction of the clutch. The clutch never gave me any problems it was just the car lagged when trying to accelerate speed.

About 10 feet from my parking space, I prepared and aligned my eyes to pull forward into the space. Suddenly, my car accelerated and I jumped the curb, and crashed into my apartment building, without me being able to regain control of the car. Now I've been parking for many years, and I was not impaired in any way, shape or form. How fast must that car have accelerated to what MPH? I'm terrified to drive the vehicle. I have noticed the whole time I had the car about a "lurching forward", be it a red light or in line at fast food line drive up. Once it starts lurching forward I'm worried im going crash into the car in front of me in line or at the red light.. Also, sometimes when the light turns green, I hit the gas and the car doesn't go anywhere. Then violently throws the car forward accelerates.

Vehicle has entered into limp home mode multiple times, last time resulting in near collision from behind as throttle and transmission shifting become inoperable.
