I have a 2020 GMC Sierra 1500 5.3, just had lifter failure that damaged the cam also, total repair out the door was $8100. This was at 77,000 miles, I didn’t realize this was even an issue until it happened.
Does anyone know if they repair the engine with the same original OEM spec lifter from 2020 that failed or has the lifters been updated since then to be more reliable? I love my truck but if I have to worry about lifter failure moving forward, going to have to bail.
