My wife is now driving my 04 gmc sierra around town because she is scared of being stranded again in our month and a half old buick enclave. It was fine until after about 3000 miles when we had our first oil change done at the local dealer. The first time it happened was in our garage adn she told me the hatch wouldn't open, I found a dead battery. I charged it for 3 hours and then let it idle for about half an hour then my wife went to work. About 8:00pm that night she called and I had to pack up two kids and go give her a jump start. The Buick was fine for about 3 or 4 days then we found it dead in the garage again. I trickle charged the battery for about 16 hours then started it and everything was ok. The car sat for about 12 hours and my wife started it to go to work and everything was fine, The volt meter read about 12.6 volts before starting which is good, she went to work on a night shift(12 hours).Needless to say when she got in to come home the battery was dead :banghead:. I took it in to the dealer and they had it for a whole day and said they couldn't find any drain on the battery. Now my wife is scared to drive our brand new vehicle because she may or may not get stranded.
