This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.

Having intermittent start problems that seem to be caused by an electrical problem. The truck will not start or turn over while dash warnings indicate "parking asst off" and "traction stability off". initially it was just these issues along with the non start but now 4 weeks and $588.04 later includes the power locks going up and down by themselves and ac blowing hot air. Fortunately the vehicle was parked when I tried to start it. The Chevy dealer said at first they thought it had been struck by lightning then claimed it was the onstar module which they wanted to replace at $699. I advised them I don't use onstar so they said they could disconnect it from the rest of the vehicle and that worked fror a few weeks. The truck drove beautifully but now is back at the dealership and they want to replace the onstar module again which clearly isn't the problem. I love the truck but can't afford several hundred dollars every few weeks on this. I need a real solution to this problem and I know that this is a known issue because I have researched this problem and found it to be a GM issue that is affecting many, many others beside myself and as far back as the 2006 models. If it goes back that far and with so many other people there has to be a solution. Please somebody help me find it!!!!
While in operation at 55 mph the engin power was reduced after three service appointments repair attempts. Reduced power mode is a condition inserted by the engine controls module as a result of the fly by wire connection. The result was a quick speed reduction to 20 mph as max speed. Dot requires 45 mph, unsafe!
Lost complete power of car. Could not steer, or brake. Happened in snow. Since that time it has happened 5 other times. 3 in the last week with the snow and rain. There is a great potential for loss of life. Have researched this for months and there are many Avalanche owner with the same problem.
The vehicle doors will unlock and lock several times while I'm driving, it will also cause the dashboard, clock-radio and onstar system to flicker off and on. Then it will start to throw error messages on the dashboard about stabilitrak and theft deterrent systems disabled.

Commuting to work approximately 3 miles away from home, traveling in the dark at 7 am, I flipped my high beam headlights on and suddenly all electrical function went out of the automobile (no headlights or electrical instrumentation). This lasted for approximately 1 to 2 seconds and suddenly and all electrical functions was restored. Things after that seemed ok, but about 6 miles down the road the engine "service stabilizer control light appears". I traveled another 11 miles to plainville, and when I arrived the "stabilizer control light went out. I took the vehicle to a mechanic them to evaluate it. After several hours and two diagnostic tests all electrical function reflect normal. The problem could not be isolated or duplicated. I contact General Motors yesterday, to report the serious safety defect and how critical this is and I could have been injured or killed at that speed driving in the dark. I also asked them if they have had similar reportings of this occurrence and received a mixed response. There response was bureaucratic, take it to a Chevrolet dealership. I said no. I am not paying another $150 tell me we cannot find a problem. I kept stressing there is a problem "vehicles suddenly do not just dropped off all electrical power and function and magically just come back on". this is not normal for any vehicle to happen. I also informed them as a courtesy I would speak to them (General Motors) first before I contact this Agency. I also tried to emphasize to them, people should have a direct line of communication to the corporation to report safety and life threatening issues directly. The nature of the response is basically we don't do anything unless we receive information from GM service departments.
