Check engine light came on for the TCM. Car has had issues shifting (very rough shifting) and the manual shift option does not work. Was told the TCM had to be replaced. Attempt was made to replace it with a refurbished TCM but that couldn't be programmed to the car. Was then told I would have to buy a brand new one, which is very expensive, and that there was no guarantee that would fix the problem. Car can not be driven over 20mph without risking burning up the transmission. Car also jerks forward very hard when trying to gently accelerate.

'service air bag' had been on my computer screen for a few days and isn't going off. I purchased this vehicle used and they told me it means something is unplugged. I took it back only to have it come back in months later. It sometimes happen as I'm driving but lately it's there when I turn the ignition. I also have shifting problems out of first gear and sometimes second. I was told it's the wave plates and it's a known issue. How are these vehicles still being sold with the same issues over and over! This happens all the time as I'm driving.

This vehicle will all of a sudden start swaying from side to side and the stabilitrak light will come on. In addition, the transmission will suddenly seize up, losing acceleration and nearly causing a crash. The engine will also state that it is overheating, all of a sudden and the vehicle will shut itself off and smoke will start coming from the engine. This has happened while going between 35 and 65 MPH. On the streets and highways. My children in the bucket seats in the back were sleep and their heads hit the window. They sustained injury. That was on a regular street and the speed limit was 35 MPH. I was within or slightly under the speed limit when the vehicle started swaying unexpectedly. When the road is wet, it will sway from side to side on simple curves in the road. I have had the transmission replaced twice. Due to the safety concerns and fear of my family being fatally injured, it was around christmas time. I have had to park the vehicle. I have contacted gmc by phone several times with no response in return. I spoke with someone and was informed to report it to the federal safety agency. Maybe something can be done about this before a death occurs.
