general problems of the 2017 Chevrolet Silverado 2500

Transmission failure for the second time. The first time it happened it had 51,984 miles after I got it back, it happened again after an additional 41 thousand miles.

When transiting between airport and home in very remote area in subzero temps the def warning system suddenly came on limiting vehicle speed progressively. No services were available both at this time of day and in this very remote area. There needs to be some way to override this system in the case of potential life and death. There were no warnings that this system was going to activate, it simply came on. The system had plenty of fluid but it appears the def heater failed. A vehicle should have an override for life and safety matters. Vehicle is going to a diesel mechanic for service now.

At about 62,000 miles the vehicle check engine light came on with codes p0700 and p0741, the rpms go up as you accelerate but will not shift unless you let off the gas pedal. Reaching 5-6000 rpms. Had mechanic drop transmission pan no metal found. Reading several tsbs on this issue the transmission should be recalled. Also when towing camper there was some electrical issues when the trailer was contacted the truck would not recognize trailer connected, had to shut the truck off for few minutes and restart to recognize the connection. Truck also lost power when trailer was connected and ran very sluggish, also experienced the shifting issues.

I was stopped at a stoplight, when the light turned green, I let off the brake and the truck took off at full throttle. I never even had time to touch the gas pedal, it went from 0 to 60 in less than 1/2 a block. I thought it may have been a cruise control issue and tried several times to turn it off, but didn't slow down one bit. 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. The entire incident lasted about 5 minutes, but if we had snow or ice on the road as is usual this time of year, it surely would have resulted in a serious accident.

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. After 3 different attempts to get this resolved I filed a compliant with gm case # 8-3228178744 that remains unresolved as of today. There are thousands of gm 8-speed transmission owners highly upset over this as many if not all escalade, corvette and truck owners have this issue. A mandatory recall is in order. In my opinion this is clearly a safety issue that should be addressed before someone is seriously injured.
