hello hummer owners,
i want to buy a hummer h3 and before i do i just want to know what are some common problems hummer owners come across during the time of yall ownership? thank you in advance.

 

On my 07 H3, am approaching 50K miles, no problems so far except a bit of wind noise at first. Fixed by the dealer.

Oh, and that time the left rear window got smashed in the parking garage. But I can't really say that was a GM/Hummer issue.

 

The transmission can be a weak link. i had problems with mine and only had 660 miles on it.
