Chevrolet Avalanche won't start problems

Filed Jul 22, 2020 · Driver assistance · 171,000 miles · FL

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!!!!

Asking if anyone knows about the 2010 chevy avalanche and the ECM problems that alot of people are having , the check engine light came on and the display showed reduced engine power, service traction control, and service stabilitrak. It would not go in gear , nor would it start , this had happened to the truck three times now , the first time it would not go into gear and it stopped and would not start at all , so I took the negative battery cable off for 30 minute and it fixed it . The second time all the light and buzzers went off , I had lack of power and the check engine light came on and the display showed reduced engine power, service traction control, and service stabilitrak while I was driving it so I took it home , I was lucky that I didn't get in a wreck because it dropped drastically in speed all at once , again I took of the cable , and went to have the diagnostic reading done at a parts store , the next day I drove it to my mechanic and he cleared all the history on it and told me to call when it happens again , it seems that the 2010 avalanche has this problem alot , so today it happened again , for no reason ,

We were driving down i20 when we were coming off the off ramp and the stabilization light came on and we got to the stop sign to turn right and as were take off it shifted really bad out into 2nd it jerked really bad and we had no power we made it home and now it turns over but will not start. 2007 avalance it has 50,000 miles. I have been talking to other people on car gurus and there are thousand on that sight having the same problem were having. And the sad thing is we dont have the money to have our truck towed into town and get it fixed. Becasue they tells us that they have so many people having the same problem. I feel like gm should do a recall or people should be able to do a group lawsuit toward gm for such a big deal like this is. And also our dashes are all cracked down the middle. Which on that sight there are alot having same issue.

There is an issue with moisture. First incident occurred in snow. Traveling around 55 MPH when I hit a patch of snow on the road and the truck stalled. At that time, I also lost steering ability and braking ability. Truck would not start. Towed to mechanic. Real issue never found. Basically dried out and started again (2) days. Second incident happened during rain. Went through a small puddle at 40 MPH and had the same issue. Towed again and started right up the next day. Third incident happened last night, april 25, 2013 while driving home in a driving rain storm. Did not hit any water just stalled on it's own. Again, stalled and would not start. Towed for a third time. Talked to chevrolet this morning they said there were no recalls for the issue but I have checked online on several different forums and it seem to be a problem for many folks.

Gas was dripping out of one of lines, after smelling gasoline for a month or so. Today the truck will not start and I'm afraid to jump start it.

Dt*: the contact stated while driving 35 MPH, the vehicle stalled. After pulling over the side of the road, the vehicle was put in idle and the contact attempted to restart the engine but it would not start. There were no warning signals prior to the incident. The contact was told by a friend that they experienced the same problem with their vehicle which was the same make and model. The problem was caused because the camshaft sensor in the ignition malfunctioned. Neither the service dealer nor the manufacturer were contacted.

I recently purchased a used 2002 chevrolet avalanche 2500hd 4x4 with a 8.1 litre engine. The vehicle has approximately 51,000 miles on it. The first problem I noticed was that the engine would crank, but it would not start immediately. The next problem I experienced was that the engine shut off while I was driving it. This resulted in loss of power steering and power brakes, but more importantly, I was not able to maintain the posted 55 MPH limit, and I had to dodge traffic while trying to steer my "dead" vehicle onto the shoulder. The vehicle did restart and I was able to resume as before. This has happened to me at least 4 times. Thus far after 3 trips to the dealer, they have not been able to repeat, diagnose, or repair this problem.

Consumer 2004 avalanche sometimes will not start and stalls while driving. ***no answer required*** *ts the dealer attempted to solve the problem but failed several times. The consumer's wife experienced this problem while traveling at high speeds, losing the power brakes and power steering. On another incident, the consumer's wife was turning into an intersection with a sufficient amount of time and the vehicle stalled again, nearly causing a serious accident.

Dt: when trying to start the vehicle would not start. The consumer inspected underneath the hood and discovered that the positive side of the battery melted. There were no previous problems with the battery. The consumer consulted the dealer, and the vehicle was out of warranty, and no recalls were involved. The consumer had the vehicle towed to repair service shop, and they replaced the old battery with a new one. The technician noted that he had never seen anything like this. A friend searched the internet and discovered a class action lawsuit pending against AC delco batteries. This was the original battery that came on the vehicle. It was an AC delco factory battery. No problems since the replacement.
