2 weeks ago I was driving on the highway doing 65 mile per hour and suddenly my truck started shaking and. Suddenly completely shut down lost power brakes stiffed and steering wheel as well. I safely pulled over to try to restart the vehicle and on my dash board light came on engine, TCM light and a light with a little car with hash marks called dealer the technician said it was a ecm. Problem and that am looking at a price of 7,000 dollars which is not in my budget reaching out to see if is maybe a manufacturing issue

When placing the vehicle in reverse, the infotainment screen goes to full brightness on the reverse camera, making it difficult to see at night by lighting up the cabin causing interior reflections when trying to see out the windows at mirrors or behind the vehicle. There is no way to adjust the brightness setting. This is a pointless feature as the camera becomes the required visual point and is sometimes obscured by dirt or water so the driver is forced to fight the bright useless screen to see out the windows.

I was traveling on a two lane highway, a semi in front of me and a truck behind me. A warning message popped up on my dash “Service Emissions System- 65 mi before 65mph max speed”. And within 5 seconds of that message popping up, the engine detuned itself. I pulled over as quick as I could, but I only made it partially out of the road before the engine shut down completely. I couldn’t start the vehicle again to get it the rest of the way out of the road. I was 40 miles from the nearest town on a Sunday. I had to turn on my flashers and sit outside the vehicle for 4 hours until a tow truck was able to come get me. Thankfully at the time of incident I was on a rural highway and I wasn’t hurt, but I could have been seriously injured...

Key sticks in ignition on accessory and cannot be removed. Service Bulletin generated by GMC. Available for inspection. Safety: with key stuck in accessory position battery goes dead in 4-6 hours, potentially stranding occupants and depending on location possibly creating a traffic hazard. Three attempts by GMC Fremont CA to repair so far. They have confirmed the problem. No warning or message.

I have been receiving the “Service Trailer Brake System” error intermittently. The only information I have been have to find around this is a defective wiring harnesses between two modules. This defect is not due to wear/tear and has been reported as a defective part on multiple GMC models. When this service error pops up it is distracting and very unsafe for driving as well as dangerous when towing as the driver has no idea of the trailer brake system is functioning properly..

Vehicle has less than 25,000 miles. Over the last 3 days, after vehicle is put in park and turned off, the key will not always rotate back to the 'off' position, and can not be removed from the ignition. This has happened at least 6 times over the last 3 days. Managed to remove key by turning vehicle back on and driving back and forth a few inches, then trying again. Took multiple tries on some occasions. With less than 25,000 miles, nothing should be worn out... Safety concerns:The possibility that the key will completely fail to be removable, meaning that if the vehicle must be left unattended, it must be left unlocked and in a condition that it could be started and stolen or driven by a curious child. The possibility that see-sawing back and forth in a parking spot could lead to an accident. The possibility that the...
