I have a 2007 GMC Sierra Vortecmax with a factory remotr start.
I love the truck, however, within the last four months the trucks battery has gone dead.
FIRST time took the truck camping, didn't start it for two days= DEAD. Roadside assistance charges it, I let the dealership know "If it happens again let us know"
SECOND time took it camping again for two days. Same thing its DEAD (No cell coverage this time), luckily found someone with cables
(The truck was not being used for lights, radio, nothing while camping)
Take it to the dealership they say everything checks out but if it happens again dont get a jump we'll come out and look at it. Their Diagnosis " Maybe since your ONstar expired Onstar keeps waking up the modules"
(ONstar hadn't expired and thats a pretty stupid excuse considering how many vehicles are out there not getting dead batteries with or without ONstar services)
THIRD time, leave it for three days at my house, go to start it up, DEAD. Call them, they come out cant find anything wrong, jump it take it to the shop, They say "its your dome light, left on"
(Well, the dome light wasnt left on and even if it was every other vehicle I have ever owned has run down protection) So this time they disable my entry and exit interior lighting, Hell, I only paid $40,000 for the truck why should I expect the luxury of interior lighting
FOURTH time, the truck sits for 18hours wont start, this time it gets jumped and dropped off They keep it for two days cant find anything wrong.
Now I've just picked up the truck drove it for two hours on the highway turned it off, I restart it and the truck barely gets started the internal clock is reset as if the powere was disconnected and re-connected. I reset it go to the store and start it up again and it does that low power chug but does start.
Sorry for the long post but thats the whole story. Any ideas? I'm getting ready to drop off the truck with the keys. Like I said I love the truck but when I'm paying practically mortgage payments for the damn thing I expect it to start when I turn the key.
