H2 Issues and Gremlins list

[PaHumBug]

These are the ones I've dealt with on most of my four H2's I've owned, and heard other people having the same issues:

-wiper module not sealed properly
-front differential seals leak often (typical with all GM)
-interior squeaks & rattles (old stlye, can't comment on new style)
-stepper motors in instrument panel

[Rico001]

I'll agree with the Stepper Motors in the instrument panels

The $150 shift cable ( p.s. I want a big refund for the difference of the cable and the clip)

and I would like to add the crappy black plastic in the front and back bumpers that will never stay black

the water leaks around the clearance lights and corner lights

Lynch Hummer carried a flat black metal replacement for the front center bumper and side pieces - I had them on my 2004 H2 and I think they ran about $650. I used to see them on Ebay now and then. I've tried everything on the back bumper, including Back to Black, and Bart's Black Bumper paste, but Griot's Bumper reconditioner seems to last the longest on my H2.

I had the three piece metal front bumper set on my 05 H2 SUT - I wish I had taken them off when I traded it, but I thought at the time they would always be available after market. I bought them off EBay in 2006 and someone had chromed them, so I sandblasted them and painted them flat black.
I also siliconed under all the roof marker lights and have never had any water issues.
