Engine started running extremely rough shaking vehicle. Various warning lights lit up. Took vehicle to dealer and was told that I need a new duramax engine because the cylinders are scored. 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.

Driving on highway at 40mph while towing a trailer the rear tires briefly locked up, then the Check Engine Light came on and vehicle went into limp mode. Dealer confirmed transmission valve body issue. Same problem as recalled on earlier model year vehicles. Seems like 2023-2025 vehicles should be added to the original recall to ensure support and long-term warranty protection.

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.
