Battery problems of the 2003 GMC Envoy

Three problems related to battery have been reported for the 2003 GMC Envoy. The most recently reported issues are listed below.

car   Battery problem 1
Failure Date: 05/12/2011

While driving, several indicator lights came on in the instrument panel. (abs, seatbeat, battery primarily) these lights stay on for a while and then go off, one by one. After putting the car in park, the battery life meter dropped to zero. I turned the car off and the car would not re-start. After having it towed to a repair shop, the battery itself tested that it was good. I replaced the battery, anyway, hoping it solved the issues, but the lights on the instrument panel continue to turn on while driving. After a day or so, they turn off and then days later will come on again. I have had this car checked multiple times by two different repair shops and neither could find a solution outside of replacing the instrument panel. After searching the internet, this seems to be a known problem with this car and other GMC models have been recalled for the same problem. Why hasn't the Envoy been included? it's obviously a problem with this model as well. (although, other than the airbag recall, I have never received notices about any other recalls regarding my vehicle even though it appears there have been other issues).

car   Battery problem 2
Failure Date: 03/09/2011

The contact owns a 2003 GMC Envoy. While driving approximately 35 mph the speedometer reading began to fluctuate. The contact stated that while at a stop sign, the speedometer displayed 50 mph. The fuel, rpms, water temperature, battery and the oil pressure gauge fluctuated as well. The vehicle was not taken to the dealer for diagnostic testing. The vehicle was not repaired. The approximate failure mileage was 120,000.

car   Battery problem 3
Failure Date: 10/03/2003

October-03 to March-04, between 800 and 3000 mileage: several dual automatic climate control system problems. Temperature would run berserk (very hot in cold weather when set at 55f, no ac in hot weather). The radio would loose its preset stations. Dealer could not identify problem (no code was set) and told me to return when condition repeats without turning off the engine. He finally found a code indication communication interruption and low battery voltage. No action was taken. The problem resurfaced temporarily again in summer of 2005.
