I am very disasified with the way the issue has been handled. I drive a 2010 chevrolet avalanche ltz with 111,000 miles on it. I purchased this vehicle in 2005 with 38,000 miles. A year later during the summer time I began to have electrical issues (while in motion vehicle guages start spazzing out going up and down, radio cuts in and out, door locks cycle up and down and vehicle stalls, doesnt seem to accelerate and shift into second gear. I have been stranded in the middle lane of the freeway traveling 60 miles per hour when suddenly it begins to act up. This is a major safety issue with three children in the vehicle and multiple cars driving at the same speed as I try to get over to the shoulder to shut off my vehicle but seems stuck in neutral preventing me from quickly getting off the free way. At times I will cycle the ignition key off and all power cuts out. I hear a clicking noise and lights flicker back on, which is my cue to cycle the ignition key back on. Sometimes it works and others it doesn't. At time power doesn't come back for at least 5 minutes. This occurs sporadically during the spring and summer times. I have taken it to the dealership where they were unable to diagnose the problem, stating they couldnt duplicate the problem. They assumed the ignition switch so that was changed but problem continued. I contacted chevrolet where they opened a case but it troubles me that they work on a case by case and stated they arent aware of multiple similar complaints. Vehicle was dropped off again where they still couldn't diagnose the problem but did research and found the cable may possibly be the reason so that is still pending. If this is so common and a major safety concerns on the highway why hasn't there been a recall for chevrolet. I have attached a document sent from the dealership about the cables. Chevy needs to do something about the electrical.

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.
