Three problems related to battery cable have been reported for the 2003 Chevrolet Avalanche. The most recently reported issues are listed below.
Engine stalls shortly after starting. Unable to get any response after the initial stall (it would not crack). Battery cables must be disconnected from the battery and reconnected after two to three minutes in order to restart the vehicle. No engine trouble code displayed after the incident.
Speedometer sticking on 2003 Chevrolet Avalanche 1500 4wd,nothing leads up to it just driving and it sticks at a certain speed wont correct itself,to correct it you have to unhook battery cables and then it is ok for a while until it sticks again,this has happened over 4 times now have been waiting for a recall to fix problem. This can not be caused by bad driving by owner or improper maintenance,this is something electronic.
On sept 5th 2004 while parking my vehicle it lost power and vehicle came to a sudden stop. I was unable to start my vehicle. Upon checking the engine I found that the battery had exploded and I found that the positive battery cable had come off completely along with the battery terminal. I do not know what caused it, but I bought another battery and the vehicle worked fine. I am just worried that it may occur again. Has there been anything simlilar occur with other vehicles like mine? I have kept the old battery and will contact the dealer where I bought my vehicle on 9-7-04, due ti holiday I was unable todo anything else.
