Consumer Description

Vehicle experienced engine failure while driving. Loss of power in traffic. Inspected by dealer and determined to have lost compression in cylinder #5. Initial inspection determined that lifters and camshaft would need to be replaced. This issue is the same common problem with this year model (2021) Chevy Silverado Trucks as noted in TSB #N212353840. At time of purchase dealer did not notify me that these trucks were experiencing these issues nor did they complete the suggest repairs prior to the sell as described in the TSB.
