“Was doing a frame inspection on my hummer h3. Turns out the rear left frame rail is completely rusted through. And there are parts hanging on by a thread. I have found many complaints online about rust in this exact spot( rear left frame). I believe this issue should be dealt with immediately. Someone could be killed. The car is not that old and no other car of this age and mileage has this amount of rust penetration through the frame. GM needs to be held accountable. THIS IS A MANUFACTURING DEFECT.”Owner report · Unknown Or Other · Nov 2025
