Open the full vehicle complaint log (all categories)The problem was unknown to me and probably would be to any vehicle owner that is not a mechanic. I was driving a death trap and didn't know how easily it could have been a serious problem. The driver side leaf spring bracket had completely broke apart from the frame on the upper drive side corner in an area that without getting underneath the vehicle with a flashlight and specifically looking for would be impossible to see. The only reason I know about it now is because I took it for an inspection and it failed due to this structural defect which the technician informed me was a very common issue with the 2007 H3 vehicles. He said that if I had been on a highway at 65/70 mph and this thing broke completely free the axle would swing out behind the vehicle on the drive side and cause an uncontrollable crash that could lead to severe injury and possibly death
