NHTSA Complaint #11628127 — 2021 CHEVROLET SILVERADO 1500

I bought my 2021 chevy silverado 1500 Lt crewcab in march 2021 it had 5000 miles on it I had it for 2 weeks when it started shaking and the engine light was flashing. Took it in to auto nation cheverolet and they had it for a month. when I got it back and started the vehicle the engine light was still flashing. They had to change the lifters on Bank 1 because number 8 cylinder lifter was bad. why didn't they change all the lifters. 3 years later I am having the same issues getting a misfire on number 4 cylinder truck shaking and white smoke coming out of the exhaust. Also the dash lights up with service parking break and service esc when the engine light flashed. ofcourse my warranty is exceeded and GM knows about this problem with the 5.3 and 6.2 engines and won't issue a recall. it is a big saftey issue as your vehile looses power or shuts off. this shou;dn't be happening especially when your vehicle is fairly new. this is twice now this is happened in 3 years and now I have to pay out of pocket to get this fixed because gm won't issue a recall on this known problem that is happening to thousands of customers.
