2023 Chevrolet Silverado 3500 Problems

The valve body assembly is not letting it to shift right when driving from 50mph to 60 mph it has a clunking noise I have it replaced and is still not working correctly GM knows there is a problem with the 10 speed transmissions I have a 2023 3500 diesel with the same problem as the recalls on the 2020 to 2022 years It is doing the same thing as the 20,21 22 transmissions are having.

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.

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. They need to honor these problematic vehicles.

TRANSMISSION UNEXPECTEDLY DOWN SHIFTED HARD. VEHICLE HAD TO BE TOWED- HIGH RPM/LOW SPEED/HIGH TRANSMISSION TEMPS. DEALER STATED THIS IS A KNOWN PROBLEM WITH THIS TRANSMISSION - CONTROL VALVE BODY. TRANSMISSION DOWN SHIFTED HARD CAUSING REAR TIRES TO CHIRP. FORCE ON DOWN SHIFT WAS INTENSE AT 25MPH. IT WAS SO INTENSE MY WIFE AND I THOUGHT OUR VEHICLE WAS REAR-ENDED. THIS IS A HUGE SAFETY ISSUE. THIS COULD HAVE BEEN TRAGIC IF I WAS TRAVELING AT HIGHER SPEEDS OR TOWING MY 5TH WHEEL TRAILER. PER DEALER - THIS IS A KNOWN TRANSMISSION ISSUE WITH GM/CHEVROLET. NO REPLACEMENT PARTS ARE AVAILABLE. MY VEHICLE HAS BEEN SITTING AT THE DEALERSHIP FOR FIVE WEEKS NOW. THERE WERE NO WARNING LAMPS, MESSAGES OR OTHER SYMPTOMS PRIOR TO FAILURE. TO SIDE ON CAUTION, GM/CHEVROLET NEEDS TO RECALL THESE VEHICLES BEFORE SOMEONE GETS SERIOUSLY HURT AND/OR KILLED. I'M TOLD GM/CHEVROLET/ALLISON REPLACED METAL BALLS WITH PLASTIC BALLS IN THIS VALVE CONTROL BODY AND HEAT IS SHRINKING THE PLASTIC BALLS CAUSING THE PROBLEM.

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.
