TRUCK KEEPS DYING EVERY OTHER WEEK

[HUMMERICH23]

WELL SHE DIED ON ME AGAIN this morning while i was going the closing of my new house (not very pleased and let the dealership know). This time i drove it the night before with no problems at 11pm. Went out to start it 7am today and it was flat DEAD. Lights barely even had a glow to them, this is the deadest its been.

Made a list of the things you guys have told me, printed them off and gave them to the service manager. Also got the manager of the dealership involved who has been a great help/friend since i bought our first Hummer two years ago and we talked for a while. I told them i wouldn?t even bring it in until they at least knew what the Fk they were going to do. They had it 4 days last week and couldn?t come up with crap. That really pisses me off. I told them i went on Google for 5 mins and got a laundry list of things along with what you guys told me and they had it 4 days and did shiiitttt.

They are leaning towards OnStar running at night and will pursue that tomorrow. I got a question for HumTech or anyone who might know; Do you guys think any of this had to do with my Hot Tune on my PCM and would that mess up the idle levels or how the pcm controlled the alternator etc. That is the only thing i could think that might be a reason for this, but like i said i have had the tune Since June and now 8-9 months later why would it cause this. I just wanted to know for sure if they give me crap for having a tune and blame that i can say it has nothing to do with what?s going on.

You know if your onstar was upgraded to the newer system?

For those that still have the old units, like myself... What are they doing now that the network is unreachable? Even if they are not activated and not getting signal, could they be continously trying to connect to the network? Cell phones w/ low signal, crank up the power to try to get signal..

I would kill for a device I could plug inline to my battery that would log the draw at say 5 minute intervals. So i when i have a dead battery i could go back at see what the draw was over a time period.

I live right next door to my office, so i dont drive alot, truck usually sits from friday-monday. I keep my tools in it, so i'm getting in it maybe 5-10 times over the weekend. I need to check what the draw is when I open the doors. I know when I first hook up the battery, its about 7amps.

I doubt very much pcm programming has anything to do with it.

there's a TSB on this for all trucks and h2's-

Faulty Ingition switch, not indexing properly causing 300-500mA battery drain.

Thats right in the range of draw I'm seeing. Gonna tear apart the column and disconnect the ignition switch see if my draw goes away.

[HUMTECH]

If its not indexed right you will see the odometer stay lit up

So after two more days in the shop they have NO IDEA what to do or what is wrong. Can not reduplicate the battery dying and they contacted GM technichal service or something and they pretty much blew off my complaint and were absolutely no help. All test are normal they keep telling me and all they do is the same dam amperage test at night and thats it. I told them to please do more or look into other things like ignition and starter but they said its fine.

I think part of why it dosent act up at dealer is because they spend 8 hrs charging the battery, then dont drive or start it at all and slap on the amperage meter and get nothing. So i told them to please do more so the manager is going to drive it home, use the remote start everytime starting it, and put the equipment on at home and check in middle of night and morning.

To say that i am fustrated is an understatement with what the truck is doing and why they are soo poooor at figuring it out. And to put icing on the cake the h3 they gave me an 09 with 500 miles on blew its transmission on me and had to drive it 40 miles to dealer going no faster than 40 because thats all as fast as it could go.

Go to Walmart and buy a Dura-Start Max for $76 they have a 3 year free replacement warranty. This way you can get rid of the factory crap replacement and if the new battery doesn't solve the problem, in 30 days, you can get your money back. I worked for Exide for 6 years and believe me new batteries all not always "new". Battery's that fail quality checks are reworked and sent out to customers on the same pallet as the new ones. You can't tell new from reworked from the outside but on the inside it can get scary!
