Owner report 11581689 · 2024-04-08 (April 8, 2024)
I received a p0747 and p0700 transmission codes on my GMC sierra 3500. It would not engage above 3rd gear and I almost was rear ended by a Semi truck because I was unable to speed up. The vehicle CEL turned on and "Engine power reduced" notification appeared on my cluster. Engine RPMS were at 2800 rpm and my speed limit would not go past ~40mph. I currently have my vehicle being inspected by the local dealership. The vehicle currently has ~19,300 miles

Owner report 11604335 · 2024-07-24 (July 24, 2024)
Transmission had a hard shift which jolted the truck switching gears to a lower one unexpectedly. It caused my body to jerk back. It happened 3 times. 2 were mild but the 3rd time was extreme. Always while accelerating. Average speed was about 50 mph when this occurred. Dealer has confirmed a failure of the transmission valve body. If the transmission were to be put in park while traveling, it could cause major accident and injuries. After the 3rd time the engine warning light came on and the truck went into limp mode.

Owner report 11570305 · 2024-02-06 (February 6, 2024)
CRITICAL PART FAILURE - The master cylinder attached to the brake pad is leaking at the seal where the piston is depressed into the cylinder. It's leaking brake fluid onto the driver brake assembly and some sort of cable. While this is repairable under warranty, this should NEVER ever happen on a vehicle. Arguably, the main part on the most critical system on the car - the brakes. Please investigate whether GM should be responsible for replacing this part on any affected vehicle for the life of the vehicle Thank you for all you do to keep us s…

Owner report 11595266 · 2024-06-19 (June 19, 2024)
We’ve had issues with the electrical system/brake lights when we hook any trailer (horse/boat/utility) to the truck. One issue is that the system shows unconnected and the trailer lights blink or do not work. We’ve brought this in to the dealer 3 times and they have yet to resolve the issue. The other issue of melted plastic on our rear sliding mirror. It just appeared one day, possible after using the rear defog button. We took it to the dealer and they also do not know what is the issue. We found several other blogs where owners have had the …

There are 2 issues with this vehicle: #1) The rear window defrost causes an electrical issue that melted the plastic on our rear sliding window. Dealer claims we put something hot against the window but we did not. This appeared after we used the rear defrost. Several other owners have complained about this as well. #2) The vehicle is advertised as having adaptive cruise but it does not have this feature.
