Started having a rubbing sound in rear end of vehicle. Took it to dealer. Brake calipers are a issue on this model and dealer says, “ found updated rear brake calipers with deflectors to help with dirt in rear calipers/not covered under warranty customer pay expense”, they are replacing rotors under warranty that got worn out. They want me to pay $2400 to purchase and have the “updated brake calipers” installed. If brake calipers are updated then that means there is a known issue with them. Spoke with the manufacturer and they said too bad.

July 18th 2022 16,059 miles engine issues again. This time was 21 hours from home. Cause reported was oil pump failed. New engine to be installed. Asked if previous engine issues was resolved aka lifters but couldn’t get a 100 precent yes or no. Truck now has little over 30k and from time to time makes noises like lifters chattering. I pray it’s been addressed but fell it may still fail again. Just will it be under warranty or out of warranty next time.

Lifters failed 7,588 miles November 2021. Dealer replace both lifter banks since trucks mileage was less than 8k miles.

The truck lunges sometimes, and will jerk shifting, also at variable speeds the truck will feel like it is "riding over rumble strips at a low speed" at variable speeds 30 MPH to 70 MPH. It makes for an unsafe feeling having the vehicle lunge unexpectedly, and the shuddering on the highway causes alarming panic, and reaction, and a feeling of delayed response from the accelerator. Yes, everyone says it is a known GM issue, but nothing will be done, unless I contact a lawyer. No No warnings, or lamps of any kind.

It’s been going on for some time and have taken it to the dealership for request but with no help. The transmission keeps shuttering bucking between gears this is sometimes violent but seems to be becoming more frequent. This is mostly between speeds of 50-60mph
