NHTSA Complaint #11711965 — 2017 CHEVROLET SILVERADO 1500

Bought the truck brand new, after 20,000 miles started vibrating. Took it to the dealership said it was the transmission shutters. They changed the fluid. At 50,000 miles did it again, they said GM came out with a thicker fluid, but it in there. Was fine for a while. At around 135,000 miles getting the vibration again. Also, at 140,000 miles cylinder 8 misfiring. Took it in and they tore it apart and said cylinder 4 and 8 lifter failure. Damage to cam and bent rods. Had to replace all lifters, cam and rods. Cost over $10,500, but had BG warranty used that additive every oil change so BG covered $4,000. I went by the oil life indicator on the truck to determine when I needed to change it, but apparently for engine for life you have to change it more frequently at 6,000 miles, so they wouldn’t cover that part.
