This is the third time since the purchase date of July 2023, that my Diesel 1500 Silverado has gone into ‘Reduced Engine Power’ while driving. The first date was August 2024, while traveling down the interstate. The check engine light came on. My maximum speed was reduced to 50mph, and the transmission shifting was very jerky. This was extremely dangerous with the flow of traffic traveling 70+ mph. I returned to the dealer where the vehicle sat on the lot for approximately 60 days awaiting the part (Valve Body) from GM. Components were repaired through warranty. Fast forward to February 2025, ‘Reduced Engine Power’ notification came on again with the code P0747, P700. Returned to dealer, and after a week of sitting on the lot, the technician could not duplicate the code. I requested that a new fuel filter be replaced for piece of mind. Today, 3 mos. later, as I was backing out of my driveway, my truck did not shift/engage into Reverse. I was able to roll into the road & put it in Drive, however it went into ‘Reduced Engine Power.’ The vehicle will have to be towed, at my expense, I’m sure, to further diagnose the cause. The truck does not move when shifted into Reverse, and pressure is applied to the pedal. It is extremely concerning knowing a national recall on identical GM components has been reported, and yet I have had identical issues without resolution. Despite the known problems and safety risks, especially with a child in the vehicle during each failure, Iave been left without consistent or timely support. I am requesting immediate assistance in diagnosing and repairing this vehicle, as well as a formal explanation of why this recurring issue has not triggered a broader response or replacement. At this point, Iam also considering pursuing further action through GM corporate or a consumer protection agency if a permanent resolution is not reached.
