hi i had the same problem..with mine... its the motors in the dash cluster ... their are little motors in their that wear out.. i replaced mine for about 10 bucks.. but it took alittle work to take it all apart.. or you can find replacement dash clusters on ebay or repair serice i think will fix it for 100 bucks.. but if your good with takeing things apart you can do it yourself.. the motors are pretty cheap. and the newer motors are not suppose to go bad.

I own 5 h2's (4 are limos) all 5 of them had to have their speedos replaced. Even though a few of them were out of warranty GM paid the bill. I took them to the hummer dealer they fixed the problem then I called GM customer service and said I've had this happen to 5 hummer h2's, this should be a recall. They then cut a check to me to reimburse. It was like $500 or $600 per vehicle. I think in some cases they even replaced the whole instrument cluster with the newer version.

Can't beat that with a stick. wish I had tryed that .:beerchug:

I found this, also. I would be willing to pay this price just to get it fixed quick. I am going to try the dealer first.....we had a 100,000 mile warranty on it and it just expired about 4,000 miles ago. I am glad we paid the extra 4,500 for the extended warranty...we have had more than that in repairs so far, so we got our money's worth. I love the vehicle, but what pain in the ass it has been.

I have a 2003 H2. Love it when it runs, but have to admit it has been in the shop 15% of the time I have owned it. No exageration.

The speedometer works properly sometimes, then other times will say I'm going 100 mph when I'm doing 25. Or it might say 0 mph when I'm doing 70mph. I was told by Ontario dealership, and also Cerritos that I need to replace the speedometer cluster. They wanted (Ontario) I think about $361 just for the part. I skipped the repair. Now I have found this board and am very thankful for the advice.

First, I am going to call GM Customer Service and ask if they wish to have it fixed while it currently is sitting at Cerritos for another problem. I will suggest it should be a RECALL item, and see what they say. At least they will become aware that people are learning of the problem.

If your problems continue, you may want to bring it in to Tustin Hummer. Never been there myself -- but SoCal's infamous Hummer master mechanic Mike Sabarese just moved to Tustin Hummer from Cerritos. In the past, his help has been awesome to my H2's problems. Personally, if I have anything more serious than a bad idler or pitman, I'd drive all the way to Tustin just so that Mike can look at it. 2cents! :)
