NHTSA Complaint #11697003 — 2020 CHEVROLET SILVERADO 1500

Driving at normal highway speeds, "service parking brake", "service engine", and "electronic stability control" lights illuminated on the dash with no prior warning. When attempting to accelerate, to maintain highway speed there was noticeable roughness to the engine along with a tapping sound. I slowed and made the trip back to my home under reduced power. The vehicle was towed to the dealer the following day per the dealer's service advisor instructions. Issue was diagnosed as a collapsed lifter, bent lifter rod and damaged cam lobe. Total repair cost exceeded $10,000. Internet search of this issue reports a number of drivers reporting similar issues with the Chevrolet 5.3 liter engine. If this issue had occurred in a more congested traffic area it could have caused an accident when my engine power was suddenly reduced without warning.
