Vehicle has about 58k miles It has been at the dealer for 3 weeks and they say they have no idea when they can get it fixed. It is my only work vehicle and now I have to rent another vehicle to keep working.”

“I have been experiencing the "SHIFT TO PARK" issue that GM Vehicles have been experiencing. My 2320 Chevrolet Silverado 3500HD High Country is not on the Recall for this issue, and I have approached my local dealer about it. I have not been able to fully addressed that issue yet, because I am dealing with a failed Transmission Valve Body that is covered under my drivetrain warranty, but not the GM recall for the 10L100 Allison Transmissions (GM N242454441). I undoubly have faulty parts/components contributing to this issue the fails to completely allow my truck to shift to park and allow me to completely turn the truck off and leave the vehicle.”

“The 2023 Chevy High Country Diesel vehicle for 89,000 has failed tremendously, without any warning whatsoever. I've had my vehicle serviced on a 6 to 8 weeks bases at the dealership. on March 28, 2025 I was driving in SD and the truck just failed all the suddenly. The information stated to shift to neutral and restart which I did. The truck never started and had to be towed. The first diagnosis was the high pressure fuel pump which contaminated the entire fuel systems with metal shavings. Thereby, the CP4 failed and damage all components of the fuel system costing 11,750.00 for the repair. In addition to this, during further inspecting the shop informed me the engine camshaft and lifter were also an issued and contributed to the dilemma. I then got General Motors involved informing them that now way possible this should have transpired with a new truck having only 126,000 miles. I stated this is nothing for a diesel engine and something was not adding up. At the time I wasn't aware of all the issue General Motors were having with the trucks and suvs. I told them that no way can I pay 31,000.00 for a repairs on a new practically new truck I purchased brand new.…”
