Well, just to help anyone else out with a current 2025 story of GM lifter failure.... My 2015 Silverado 1500 LTZ with 35k miles on the 5.3L L83 (carefully maintained) experienced the telltale lifter tick on the passenger side (either cyl no. 4 or 6) with hesitation under load and I had it brought (towed) to the dealership. Cylinder #6 lifter failure. Dealer quoted $4,680 to repair based on TSB 15-06-01-002H. If the camshaft was found also damaged, the bill goes to over $9000. "But you're getting a 2-year warranty with unlimited mileage!" they told me. Yeah, great. The 6-year powertrain warranty did me a lot of good (I don't think it was ever used). I've contacted corporate customer care along the way. Now I get to see what they have to say for all this, as I find this an absolutely unacceptable burden... and $9k+ is litigation territory in my humble opinion. This isn't just abuse or bad luck, we all know this is a full-blown design defect. So how's that class-action lawsuit coming along, gents?- 8 replies

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.
