I never realized that this could be a big problem that others have had. I have a 2007 gmc sierra duramax 2500hd standard cab. a year ago, i had a problem with my glow plugs so I took it to the dealer and they said their was a recall on the glow plugs and proceeded to order them. since that time, my batter was going dead. during the summer it was a few days to a week, during the winter or cold times, it wouldn't even last a day. now it's even worse. it won't even last a day. I have dual batteries and dual alternators in it. when it first started this problem, I called the dealer and they said that what they repaired had no bearing on the truck going dead. from what I read, there is a glowplug control module that can cause it. now that the truck won't even stay charged for a day and the fact that there isn't a block heater that I can even find on it, a new problem has shown up. the dome light used to stay on so I just left it on dome override so that it wasn't lighting at all. now the truck is saying that the driver door is open at all times. the right rear tire sensor is shot that it says their is only 16lbs of air in it. the dealer told me that they would need to do a preliminary diagnostic for $89 first before they do anything. at the time, i'm financially strapped and can't throw that at it. I guess I'm going to have to continue to jump the truck and hope that sometime after winter I'll get a chance to take it in and then have to replace the batteries because I'm sure this will kill them if it hasn't already. I've never had so many problems with any gm truck. oh, and the thing is also complaining about 4-wheel drive needing servicing. I think this truck may be a lemon with the other issues that I've had. I bought it new, the front wheel fell off, the front axel ate the gears for 4-wheel, that the dealer fixd under warranty, the other I had to claim on my insurance because the dealer said that the wheel fell off because of side impact damage. there has never been any damage to the side of it as long as I owned it and I'm just glad that I was driving from my front yard to my back yard and turned a corner around the house and bang, the front end hit the ground. this has just been crazy for me.
