2022 Chevrolet Silverado 1500

My 2022 Chevrolet Silverado 1500 High Country with the 6.2L L87 engine suffered a sudden catastrophic engine failure after passing the inspection for Recall 25V274 at approximately 70,000 miles and being returned to service. While I was pulling into my driveway, the engine abruptly shut off as though the ignition had been turned off. It would crank but would not restart. The sudden loss of propulsion while the vehicle was moving created a safety concern; a similar shutdown in traffic could cause a crash. The Chevrolet dealership disassembled the engine and documented multiple lifters stuck in their bores, requiring excessive force to remove, and deep cylinder-wall scoring that could catch a fingernail. The dealer determined that the block damage required complete engine replacement and replaced the engine. The dealer attributed the failure to lack of oil or improper maintenance and denied recall-related coverage, stating that the failure involved the upper engine rather than the crankshaft or connecting-rod bearings covered by the recall. I strongly dispute the poor-maintenance conclusion. Oil changes were performed regularly. The dealer told me the oil was somewhat low but still within the operating range when the truck arrived after the failure. I ask NHTSA to review this sudden engine failure following completion of Recall 25V274 and whether the recall inspection/remedy adequately addresses the risk of subsequent engine failure. I am not asserting that a particular manufacturing defect caused this failure; the underlying cause remains disputed. Availability of the failed engine for further inspection is unknown.

We were sold a 2022 ZR2 1500 Chevy pickup on 8/14/2026. The dealer disclosed "unknown" on the used car buyer disclosure form. By admission of service department this truck's engine seized in March 2026. A replacement engine was ordered, placed on back order, and arrived to the dealership in August 2026. The service department believed that the repair was done and finished on 8/14/2026, the same date as the purchase. On 8/30/2026, the truck was not running properly, not moving forward despite pressing on the gas, and lots of instrument panel lights. The truck was towed to the dealership and "fixed" They claim it was a fuel injector and separate from the issue regarding the engine.

My truck was driving fine down the road and started getting a knocking sound. I had a tow truck come pick the truck up and take it to the dealer, after about a week they advised I needed a new motor

Traveling on interstate highway at 70 mph when the truck engine went to idle and transmission tried to go into park. The dash just flashes "service transmission" and and other warnings. Engine still runs but can't shift out of park. Shifter is not responding to move the truck. Engine can't come off idle. Turn off engine. Power button will turn power on or off but won't crank engine. 4 ways flash for awhile with dash flashing then everything go blank. All electric power is lost for awhile and then dash starts flashing and 4 ways start flashing for awhile. This cycle keeps repeating. Truck has to be loaded on a truck to tow away. This is the 3rd time is has done this problem but at lower speeds before. Dealer can't find the problem yet.

The vehicle intermittently experiences transmission or drivetrain slipping, shuddering or juddering, and shaking while being driven. The symptoms are inconsistent and there is currently no check-engine warning light. The problem has not yet been diagnosed or confirmed by a dealer. I am concerned that the condition could worsen and cause loss of propulsion, unexpected shifting, or loss of control. The vehicle is equipped with a diesel engine and is within the model family described in NHTSA recall 24V-797 involving transmission control valve wear. The vehicle and affected components are available for inspection upon request.

The contact owns a 2022 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the transmission shuddered and shifted hard. There was an abnormally loud thumping sound coming from the engine compartment while accelerating. The vehicle was towed to a dealer to be diagnosed; however, cause of the failure was not yet determined. The vehicle was taken back to the dealer where it was diagnosed and determined that the transmission fluid needed to be flushed and refilled. The vehicle was taken to another dealer, and an oil leak was found. The contact was informed that a software update was needed, and that several unknown parts in the engine and a wiring harness and oil cooler needed to be repaired. The failure mileage was approximately 15,000.

A leaf spring broke on rear suspension. Bought a gm leaf spring from a dealer and gm won’t cover only because an independent shop did work. Truck is a personal vehicle not used in hauling. In my opinion and because even dealer where I purchased vehicle said they had never seen this happen it is a defective part. Only reason for gm to not stand behind it was repair not done at dealer. Truck has 112000 mi.

The transmission it erratically shifts and has a roaring sound. I also says shift to park when it is in park. It wont start when it is cold it just cranks and cranks it has since i bought it. Well when my kids and I are going down the road and the transmittion randomly starts up shifting or down shifting and whenit goes out its gonn lock up probably where fever we are. as for the starting thing when its cold its isnt the ideal to have to go build a fire in the garage just to get my truck to start during an emergency. I have had a garage hook it up to a computer to see if it was throwing any codes. It wasn't except a brake sensor. I bought this truck 2 years ago and have nothing but trouble with it shifting and and the dash always says shift to park. this is one of the worst Chevrolet trucks i have ever bought. it only has around 70000 miles on it. I had the truck about 3 month when the transmittion issue started. It has never started when it was cold out side the whole time I have owned igt.
