I had my 2021 LT Trail Boss with the 5.3L engine towed to the dealership yesterday. While driving home from work, the truck started a really rough idle, engine knocking, random misfiring, had Service Emergency Brake, Service ESC messages on the display, check engine light and several other dash warning lights. I pulled a P0300 code for random misfire. The dealer diagnosed the truck with a lifter failure. I haven't been told which cylinder(s) had the failure, but has anyone else had this issue on a 2021 Silverado? I have 6,200 miles on the truck, and this seems a bit soon to have such major issues with an engine. At what point does GM decide this is a recall and replace all the lifters? I suspect, based upon what I've read on the forums, most who are plagued with the failing lifter issue, return to the dealership with additional failed lifters.
I just picked up at 2021 Silverado. I lifted the front end with a jack to get an idea of how it would look leveled. After seeing the picture, I'm contemplating keeping the stock 17" wheels and putting 33" tires on it. Has anybody done this?
