Im back on this forum after a long hiatus. Thinking about finally replacing my 2014 Sierra 5.3 and googled "2022 sierra problems". This thread came up.
I bought a new 2013 Sierra with a 6.2, at 30k miles the engine piled up. Lifters. Traded it on my current 2014. at 80k miles, engine piled up, lifters, cam, etc etc etc.
It has since been good aside from the torque converter piling up twice, first time at 161,000 km, 1000 km out of warranty, happened on my drive home from work which was 1200 km. Second time, 100k km later, it did it again but needed a transmission rebuild/upgrade(i upgraded the trash factory torque converter). It now has 225k miles.
My last 6 trucks were GM and I'm a bit dismayed they still have the same lifter problems.
