I was driving my 2021 Silverado when i was stopped at a 4 way waiting my turn. When it was my turn i made a left hand turn and and travelled a short distance going 20-25 mph when my engine made an odd sound and shut off in traffic!. I attempted to restart it and it did noting. Truck was towed to Hendricks Chevrolet where the truck was bought and received regular maintenance. When the truck stopped in traffic there were no warning lights on the dash before during or after. Once the truck was at the dealership for inspection i was advised That the motor was sized and that number 1 and 2 rod bearings failed and were ground in the crank journals. I asked how could that happen when the the truck has had regular oil changes by them and is there an issue with these engines? I was told that they see a few 6.2 engines with these types of issues.

I had my windshield replaced and the installer said when he removed the old glass, the bottom of the glass didn't have the rubber strip accross the bottom. Our rear sliding window has had a small leak, so we asked him to check it out too. He noticed that the window also does not have the rubber weather seal.

The transmission valves failed and torque converter clutch slipped causing the truck to have harsh shifting issues, acceleration issues, and wheel-lock up. I've had to replace my full transmission and receive a new torque converter clutch, reprogrammed.

The transmission is the problem. The truck shudders. I took it to a mechanic, David Gessel's Auto Service 863-401-2860. The mechanic serviced the transmission and informed me that the transmission will need to be replaced eventually and that the torque converter is coming apart. It seems like the same issues 2019 transmissions in Chevys were having. My transmission is an automatic 8speed. The service performed fixed the problem of shuddering but now the truck is doing it again.

STRUCTURE:BODY
When it rains. Tailgate opens on it own. Either have to lock truck or quickly put into drive to prevent tailgate from opening on its own. Only in wet weather. Tailgate opened on its own in rainy weather when parked at hardware store. I began to drive away not knowing tailgate opened and lost tool box and material out the back while making a turn. Speaking with GM I was explained it’s a known issue on 2500 models but not for 1500 models.
