at about 20k miles the valve body went out. When coming off the brake and pressing the gas the engine was jerking. The engine light came on and then started to downshift. The truck was towed to the dealer and they said a few days later it was the valve body. All the miles of the truck were highway miles and no towing was ever done on this truck.

2023 Chevrolet Silverado ZR2 purchased 7/10/2023 with a 6.2L gasoline engine - Lifter and engine bearing failure leading to complete engine failure at 5920 miles on [XXX]. Dealership has been in possession of the vehicle since [XXX]. Engine failed, leaving me stranded at an intersection blocking traffic in single digit temperatures. Due to the electronic gear shift, there was no way to put the vehicle in neutral to move it from the intersection. The tow truck driver was forced to drag the vehicle onto flatbed tow truck, possibly damaging other components in the process. This appears to be a common issue that is known by General Motors without remedy. Appears to be related to the Dynamic Fuel Management system and spring-loaded lifters that fail. The vehicle has been inspected by Chevrolet Dealer, who determined it needs a full engine replacement. There were no warning lamps or messages leading up to the failure. Vehicle drove normal for over 100 miles on the highway. Upon exiting the highway, the auto start stop feature turned the engine off at a stop light. Upon letting off the brake, the engine struggled to start back up and check engine light came on. Pulled over immediately, and upon stopping at the stop sign the engine seized and would not restart. This led to me blocking an intersection for over an hour in single digit temperatures waiting for the police and a tow truck.

The PCV system plugs up in below zero weather casing the main rear engine seal to blow and leak. Currently waiting for gmc to manufacture the seal as it’s been back ordered due to so many engines needing this part. Estimate is 2 months or more wait. A loud ‘pop’ was heard the day before leaking. It sounded like an object hit under the truck. Oil drops were found the next day and dealership found the leak. Gateway in Fargo, ND is the mechanic and GMC is paying for repairs. If we were to of driven for a prolonged time, the leak could have poured most of all of the oil out of the blown seal and ruined the engine. There were no warning signs. The oil pressure seemed unstable the immediate days afterwards before being looked at. It was going down and coming back up after warming. The oil began leaking faster and in larger amounts as weather warmed above freezing.

Engine oil cooler lines began leaking oil at 800 miles. Oil leak appears to be at engine connection for line. Took to dealer where vehicle was purchased. They added dye to engine oil and clean up evidence of leaks. Told me to drive for 300 miles and call if it leaked again. It leaked again and dealer is non responsive to request for repair. Will try another dealer. Leak is significant.
