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 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.

I got a routine oil change at an old change place and then needed another one 2 1/2 weeks later. The employees at the shop informed me that my vehicle was burning through the oil extremely fast and that the oil dipstick was bare when they checked the oil level. They checked for leaks and found none. The very next day I started hearing a clicking noise coming from the engine and the check engine light was on. I took the vehicle to Autozone in order to run diagnostics on the vehicle to find the problem. The employee there said it was the knock sensor informing us that something is wrong with the engine. I then took the vehicle to a mechanic to see if the problem could be alleviated. The mechanic informed me that there was nothing he could do because of the manufacturing defects of this specific engine. He informed me of a number of filed complaints about this specific engine and it having the same exact problems. The mechanic also informed me that I should immediately stop driving the vehicle because the engine knocking and there is an extremely high risk of it blowing up. I had no idea this engine would do that and have been taking care of the vehicle through routine maintenance since I purchased the vehicle.

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.
