purge pump failing confirmed at dealership this part has been recalled on same truck but not specifically this vin . I was told I need to report it to you guys so that it could ge added.

The contact owns a 2022 GMC Sierra 1500. The contact had experienced several catastrophic failures with the engine and transmission. The contact stated that while driving 40 MPH, the vehicle shut off without warning, and lost power. The vehicle was towed to a dealer for an engine replacement. On another occasion while driving 65 MPH, the vehicle shut off without warning and the wheels locked up. The vehicle was towed to GMC of Rochester (4646 E Frontage Rd, Rochester, MN 55901), where a second engine failure was diagnosed and the vehicle was repaired under an extended warranty. Upon retrieving the vehicle, the vehicle was hesitating while depressing the accelerator pedal, with the messages "Reduced Engine Power" and "Check Engine" displayed. While attempting to reverse(R) into a driveway, the vehicle became immobile. The vehicle was towed to Red Wing Chevrolet (2500 US-61, Red Wing, MN 55066), and the technician diagnosed the vehicle with total transmission failure. The contact was informed that there was heavy metal debris inside the transmission pan. The manufacturer was notified of the failure but declined to assist. The vehicle remained with the dealer. The failure mileage was 12,000.

My 2022 GMC Sierra started hesitating two weeks ago between the speeds of 17-35 mph. It also hesitates going downhill. When I try to accelerate it hesitates causing a serious safety issue for me driving. I cant trust to move when I need to move across a busy intersection with semi tractor trailers coming at me. I can trust it to tow or haul anything anymore. This is well known and documented problem General Motors has and the company deems it "Normal Operations" which is totally not normal.

A safety call was issued; NHTSA 25V274. GM found my engine needed to be replaced due to the recall. Transwest GMC in [XXX] replaced the engine at no charge in XXX. The new engine they put in, blew up while I was driving. It blew up in June 2026, about 6 months after the replacement was put in. Around 20k miles. Before they would even diagnose the engine failure, they made me provide service records. Which I did and was found to be compliant with their recommendations. They replaced engine again in XXX free of charge. However, now they are telling me that the engine is only covered up until 150,000 miles. At the time of engine failure, I had 127,000 miles on my car. Therefore, I would only have 23,000 miles left of coverage for a brand-new engine they replaced. I am filing a complaint because I am questioning their warranty. I am questing what the warranty is on safety recall. My car is 4 years old, and now I can't rely on it due to mutiple engine failures. It's questionable to me, why they will only cover it to an odometer reading of 150,000 when the engine is brand new. It seems they should cover the part itself for 150,000 miles. Especially when it's a known issue for certain GM motors right now. I am filing a complaint, in hopes that I can prevent someone from getting seriously injured. Also, to protect myself against future engine problems. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I’m getting a shift to park on my dash after it’s already in park. This causes the break to get stuck when driving.
