was hit from behind and it caused $10,000 damage to my H3. Body Shop fixed it but now gas gauge is not reading correctly. They took it to a dealer to put on analyzer to see if date of accident show up. no date at all showed. They did not put in a new fuel pump due to date not showing. Was fine before accident. Am I stuck to put in a new fuel pump?

I had the thermostat replaced. The heater core was checked & the aculators .

I have 246k miles, and had a transmission rebuild @ 220. When driving hwy speeds for 15-20 min, I will loose overdrive and my Rpm will jump up. When it happens it is smooth, and only recognized by the increase in rpms. This of course causes the engine temp to rise. I have no other gear issues, and they all make smooth transitions.

It squeeks/rattles when I drive,,,sometimes at an idle a little bit...but stops when I brake. It sounds like its coming from the front passenger side of the vehicle. But it seems to be getting louder. Then for stretches going down the road the noise just goes away. Make any sense to anyone?

oil check light is showing kind often can you help me, vehicle run good oil is level fine, light show when vehicle stop.

was using the sunroof when car was not starting got caught on something and opened back up then it seem to die as if battery was dead but will not turn over or release the key

Clutch slipping in first gear

My hummer leaks under the pedals and rains out the onstar speaker. Everytime it rains, Im left with a mess! I do have a sunroof , checking the seal on that. Can't find a number of a hummer dealer ship to replace anything. .......

The Engine wiring harnesses are not the same. Is there a wiring conversion kit or any suggestions?

I just received the recall on replacing the harness due to a possible fire issue, however I already had to have the repair done a few months ago due to burn out that occurred within the harness. Can I get reimbursed from General Motors on this issue?

Resistor was burned through and melted to all the wires had to replace that plus blower motor too
