Hi all,
I have owned my 2005 H2 since day one. In 2008, my battery began giving me issues. I had the key turned "back" and was listening to the football game while cleaning out the bed. The truck died. It did this off and on (again while parked, off, key in the ignition) from 2008 to 2009. Battery was changed January 2010. In June of this year, my friend & I were sitting in my truck with key in the ignition and overhead lights on. Key was turned in "up" position. Battery died. Yesterday, I was sitting in the parking lot with just the key in the ignition, not "up" or "down", and the truck died. This last time when jump starting, I noticed that all it needed to start was just cables connected to the running car. It took nothing to start it. However, battery read 9, which is definitely low. All times that the truck has died, key has been in the ignition for less than 10 minutes.
This new battery is charging at 14, which is proper. Truck was serviced last week by mechanic (my dad) and he checked all of this after my last incident, so he knows it is not the alternator or battery. He thinks it is vampire power usage. Maybe a fuse. His second thought is the amount of time the exterior lights are on. Has anyone had this?
I noticed yesterday that if I take the key out of the ignition, the radio still runs and the windows still roll down if I do not get out of the truck. I am a real estate agent & I spend alot of time sitting in my truck waiting for clients at properties. Now I am worried if I sit in my truck, no key in the ignition that the truck will die.
I read in other forums it could be an Onstar issue. I do not have Onstar activated, but this issue has occurred with and without it activated.
Has anyone else had this issue? Look forward to hearing thoughts.
