Consumer Description

On April 29, 2022 between 4:45 - 5:00 pm Eastern, I was dropping off my son at work when I suddenly experienced a variety of Truck Diagnostic Error messages on the front driver display window. In addition my OnStar advanced diagnostic alert system informed me with the following system issues: Engine and Transmission; StabiliTrak stability control; Antilock Brake; and Emissions. At that moment the truck experience a cut in power and slowed down with a knocking sound coming from what seemed under the truck. I slowly proceeded to drop off my son and drove back home and parked the truck. Truck was towed to local Chevy dealer on Friday of that day. A preliminary diagnosis was done Saturday, April 30 suggesting an Engine Lifter issue. On Monday, May 2, 2022, a final diagnosis determined engine lifter failure on one side of engine bank. Vehicle is still under Warranty with 17,400 miles on it.
