2007 Hummer H3 4dr SUV
242-horsepower 3.7L I5 5-speed manual AWD w/low range
| 50000 mi US $850 |
Due to a poorly designed sunroof draining sust leaks caused sensors to get wet and tripped the warning lights to ping ABS and stability system errors. |
| 78500 mi | Seat trim was causing parasitic drain on battery. It was cracked and constantly pressing down on the power seat button. Realigned the plastic trim and screwed it into place, the drain on battery was resolved. |
2007 Hummer H3 4dr SUV
242-horsepower 3.7L I5 4-speed automatic AWD w/low range
| 100000 mi | A very poor design of the sunroof water drainage system allows trapped water to enter the vehicle's interior,often leading to excessive moisture retention underneath the carpet and ultimately causing mold and stale odors inside cabin. |
| 62000 mi US $285 |
Sun roof drains plugged. |
| 59000 mi | Exterior door handles breaking. The part that does not move has broken of of both passenger doors and the drivers side rear door over the past year. I have reattached with glue. Silaprene seems to work the best. |
