Question about Hummer H3

1 Answer

I have a brand new 2008 Alpha H3 Hummer...it hesitates off the line, bogs down and just won't hardly go sometimes, other times it rocks, runs great. It also tends to run a little hot, and I think I notice the lack of power everytime it's running hot, which is all the time

I have the same problem. Been back and forth with the dealer and GM. Everyone knows this is a problem but Hummer will not reprogram the computer. It was suggested to me to get a vortex to adjust the computer shift points but the unit is $400 and will void your warranty. Sucks big time

Why will my 2008 hummer H3 door locks with key but will not unlock with key. the key will not turn to unlock


The lock assembly in the door is faulty. It gets tricky since Hummers are no longer in production. Changing the door lock cylinders will get you a different key than the ignition. Any GM dealer should be able to get you the parts.

H3 Alpha. Vibration


the balance on ANY H1 can be critical. i am a HUMMER H1 tech. for them to say its normal is a lie. they can be balanced with the proper machine and technician. alignment will not cause vibration and it is also critical that the specs on the alignment (toe specifically) form a diamond pattern. that is to say the fronts should be adjusted in 1/16th of an inch and the rear 1/16th out. that will add life to your tires as well as good handling. H1 s are the best. anything further email me at iambanshee74@yahoo.com
