NHTSA Complaint #11709026 — 2021 CHEVROLET SILVERADO 1500

2021 Silverado 19,000 miles no indication of failure at a busy intersection about to go thru intersection and engines started knocking, multiple check engine lights on. Luckily got thru the intersection and to my place of residence which was very close by. Truck was towed to Chevy dealer. Dealer found 3 bent push rods, 3 bad valves. This engine had the lifters fail completely out of the blue. Oil changed at the dealer, meticulously maintained. Dealer only replaced the faulty bank of lifters due to mileage, seriously if it was under 16,000 they would replace all of them. This is unacceptable. This truck left me almost stranded in a busy intersection, lucky I knew well enough to keep going versus getting T-boned. I just think GM needs to do something about this. Now fast forward to 41K and I'm at the dealer same symptoms except this time my warranty is running up soon and being forced into an extended warranty. There are plenty of online claims, chat rooms, posts, etc to warrant this as a safety issue.
