2017 Chevrolet Silverado 2500 Transmission and drivetrain Problems

“Right rear wheel hub nut backed off damaging housing spindle threads and slightly bending the housing. Gm will not replace housing even though it appears that a crack is forming where it was stressed.there is a recall for this problem but my truck is not involved. Gm will not check the left side like the recall says should be done also.I believe that there is a crack starting to form and could be a problem while driving in the future.”

“Ii took my 2017 1500 silverado I purchased 11/2020 that had about 9500 miles to the chevy service center and stated while driving my vehicle when coming to a stop during the 2-1 downshifting of the transmission a very loud clunking noise and at the same time it feels like something hit the rear of the vehicle.

When we got out of town, I let off the brakes and it continued to gain speed until we hit 75 MPH. I again engaged the brakes, turned a corner to get off the road, and when I turned, the truck went back to normal. It was like a switch was turned off. …”

“Rear wheel bearing adjustment nut, stripped the threads and became lose, causing additional damage to the break rotors. It also caused the seal on the rear axle to leak. Took in to mechanic to see why it was leaking. Mechanic was surprised that I didn't lose a rear wheel. Will provide photos from mechanic when available.”

“Transmission shifts extremely hard causing a loud clunk and the vehicle to lunge forward. This is experienced a lot during slowing down at yield signs or when starting out in traffic. The truck experience a split second delay in acceleration and then suddenly shifts very hard lunging forward. Gm motors dealership acknowledges there is an issue, but they don't have a solution and GM engineers are having them tell the consumers the transmission is operating as designed despite their own service techs and service managers and district managers stating there is a problem. …”
