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)

My engine is blown. The extended warranty offered by hyundai does not cover the time period or mileage I've had deeming it useless. This is a serious problem and it should be addressed properly. I cannot drive this vehicle. I still owe on my loan. The warranty is not sufficient for the damages accrued regardless if I had signed up in time. This is dangerous, criminal and I'd like reimbursement.

When I make short trips and then turn car off for a few minutes before trying to start it again, sometimes it doesn’t restart. I have to sit there for 5-15 minutes before it will start again. Once, it died at a 4-way stop then started right back up. Today, the motor cut off while I was accelerating at 35 mph right in the middle of the road. After 10 minutes it started right back up. This is my daily driver and I know there’s a campaign for this abs/electrical issue but I need a solution immediately before I’m left up a creek without a paddle. That was so scary that I’m afraid to even get on the interstate to take it to the dealership!

Firestone said that my spark plugs 1,2,3 failed and my engine is knocking aggressively (code P1326).
