2003 H2 Intermittently Starts

Damn,

I can only say, get rid of it!

Good Luck

You have been through enough

[Suzie]

You and at least twenty other people are telling me to get rid of it. It only has 77k miles. I kept thinking that with the new engine at 49k, and new transmission at 23k, that it was almost like a new car. But that has not panned out. I really enjoy driving my Hummer on and off road....when it runs.

But right now, whether I sell or keep it, I just need to get it fixed. And I have the Ontario Hummer dealer (who claimed it was a battery problem) and my personal mechanic telling me it is not the key ignition switch. Then I have the latest dealer, Cerritos, telling me it is the ignition switch. What to do? I do not feel they have bothered to do a proper diagnosis; I believe my local mechanic who says it likely needs to have the modules reprogramed, and perhaps one of the modules is bad and perhaps not, perhaps the reprogramming will fix the entire problem including the 4x4 low light always being on and the traction coming on in U-turns.

But Cerritos dealer's service writer is saying there is no such bullentin for "reduced engine power." I believe my local mechanic. He called a tech line run by an ex-Hummer mechanic.

Has anyone had a similiar problem or have any fix advice?

With the service 4 wheel drive light were any codes found in t-case module? Sounds like the encoder motor sensor to me, not the entire encoder motor. As for the int no start, have the main ground checked from batt to engine block, seen many that were loose and caused this same problem.
