The trailer brake System sensor keeps going off making the vehicle unbearable to drive. The transmission also jerks when it gets to 7 mph. I've taken the truck to the GMC dealer over 3 times to check the transmission problem and it still jerks. This has been a on going problem since the purchase of the vehicle.

When I slow down to make a turn, my truck loses power making the turn very dangerous. I lose control of the vehicle for a few seconds due to loss of power. It is very dangerous for me to make turns.

- #11463891May 9, 2022EXTERIOR LIGHTING
The left rear tail light assembly is subject to direct wheel spray resulting in premature corrosion and failure of the lightbulb and wiring harness. Failure first occurred Within 18 months of ownership. I cleaned the contacts and packed the connection with dielectric grease. However after three years the bulb connection is now totally corroded and the circuit has failed requiring harness replacement. The problem is so widespread, replacement wiring harnesses for the left rear tail light assembly are out of stock and unavailable from GM parts. I am now using the vehicle without operating right rear turn signals. GM-trucks.com is an owners chat room with many entries about this problem. [XXX], BSME, P.E.

At low speeds my brakes do not work well. Mostly while driving at idle speeds like in a parking lot the brake pedal gets hard and the truck does not stop very easily. If you idle the truck up to a higher RPM, the brakes begin to function properly again.

I keep getting a dashboard warning saying "service trailer brake system". from what i have found, this is due to an inexpensive wiring harness being used. It's very distracting and even if i dismiss the error, it keeps coming back up.

- #11463203May 3, 2022SUSPENSION
Cross frame member ahead of rear wheels has rotted and failed. It is located behind the cab and is the cross frame that holds up gas tank and forms the anchor point for the rear shock absorbers. I have been told by dealer that truck is not safe to drive. It is now at a body shop. The suspension is compromised, gas tank could fall, and drivability safety is affected. Truck is only 8 years old, the cross member is not visible to consumer, there has been no undue use or environmental conditions to cause the rot and failure of the component. Further, the manufacturer does not sell a replacement part, so the entire frame of the truck would need to be replaced.

I took my vehicle into Clay Cooley, 1251E airport Frwy, Irving Tx. 75062 for oil change, state inspection and recall N202324251. They indicated on the repair invoice that the recall had been completed along with the oil change and inspection on 04/08/2022. However, according to NHTSA on 05/02/2022, the recall is still open for my vin #. I do not know if there is a delay with the vendor reporting the recall work, but I would like to know if it has been done or not.

- #11462940May 1, 2022POWER TRAIN
The transmission is lurching forward when initially put into "D" then when driving it seems to be confused on which gear to go into especially between 40- 50. The other problem is the truck will make a shudder like driving over a washboard but only on smooth pavement, then shift into allow gear and the engine will rev up. is this something that the dealer will repair. I'm concerned to drive it.

Check engine light came on at 458 miles. Took it in and after an hour they determined it was the ecm. They said it was bad. Now they're on the hunt for one. In the meantime, in a day the truck has started feeling like it's over shifting and then bogging down. 458 miles, really! I'm going to need a loaner for longer than I've had it and still make payments.

On 4/12/22, we were towing our 32ft trailer with putt 2011 diesel GMC Sierra truck to Big Bear Lake which is in the San Bernardino Mountains in a two way winding highway. Upon making a somewhat sharp turn up a steep uphill, our accelerator went out. We had my mother in law, our two kids and dog in the vehicle at the time. We were able to get a speed of about 5-10mph to get a turn out and turn back around. We had no reception to call for help. The accelerator gave out shortly after but we were able to ride the decline to the bottom of the mountain and as soon as we were getting to the bottom, the engine turned off on us. Although it was still a two way highway, thankfully there was an emergency lane where we were able to park and where we were able to get very limited reception to call AAA (tow truck). There were vehicle speeding past us in high rates of speed. Because we needed a specialty tow truck given the towing of the truck/trailer, we knew it would take quite a while in the mountains for a driver to get to us. Temperatures at night in this area can get to 10-20 degrees. Five hours later at 11pm we were towed home. Upon towing the truck and trailer home, we were made aware of the reason the truck broke down through a diesel mechanic, which was CP4 fuel pump failure. Upon learning this and going online, we found out this is common for this truck with the CP4 fuel pump. We also found that other companies have made recalls, eg. Dodge but GMC/Chevy has not. This is obviously a safety issue that could have been catastrophic for myself, my kids and family and am wondering why there hasn’t already been a recall through GMC. Please let me know what our recourse is or if you have any questions.
