1-factory alarm problem
2-fuel pump
3-the mirror not folding
4-water getting into the truck some how
5-wipers
6-not finding the wiper motor
7-pitman arm

That's a pretty inclusive list Boss. It would be helpful if other members could pitch in and let prospective Hummer owners know which years are affected. For example, the mirror folding problem only affects 2003 to 2005. I know the wiper issue was fixed, but I am not sure of the year. 2005?

I do not recall the fuel pump being a common problem. And what is #6? Can't find the wiper motor?

I would also add that the air bag suspension seems to come up on this forum with some regularity.

yeah thats my foul i posted all the problems i heard of some recalls but never got anything fixed at the dealer since my vin number was never on the list

but i google the factory alarm issue and some h2 2005 have that problem

have a 2006 and had oil pump issue no oil pressure any more had to replace it

had a transmission problem but put on a magnuson charger.
replaced it with 4l80 and changed gears to 4.88/1
very nice specs now

I have a problem keeping gas in my tank. I think my wife found the keys..lol

Good one!

Here's another: People automatically assume I'm a Republican. (I'm not.)

Im not (republican) either but I didn't vote for that guy. I normally try and see who has the better plan. Two months and no issues yet. I did do intake and exhaust. Runs awesome and I'm getting 13mpg! 90% highway

auto lock does not work on rear doors

This is a thread for "most common" problems. First time I've heard that one. Maybe I missed all the other door lock problem posts.

2004

1) Oil pump supposedly went out (no pressure) $1500 (have to drop front axle).

2) Won't shift out of park (fixed myself) - you have to remove shifter handle and lift center plastic console up to view detached wire (usually black). Then resolder. If it happens at a bad time (no time is good), you can lift the center console and feel for the "button" and push that in and shift into drive. That will get you home.

3) Back utility plug does not work (not a fuse either).

4) Speedo and tach have gone out (wacky-never can tell speed).

5) Alarm failed and locked us out. (fixed under warranty).

6) Drivers side fluds when it rains and Hummer is left outside.
