problem #2

Avalanche 4WD 8-cyl

  • Automatic transmission
  • 43,000 miles


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.

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.
