What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Entire frame and cross members have severe rust with perforation. Suspension attachment points to frame are severly compromised. Vehicle is unsafe to drive. Sheet metal body structure appears "relatively" rust free. The frame integrity would not be noticed unless the vehicle was inspected closely.
The front shocks are rusted through, and the body has had to be repaired for rust. This vehicle has cancer, and it's terminal. I live in the state of maine where yearly vehicle inspection is mandatory....the trooper barely passed last year.
Audible clicking coming from front automatic locking hubs, checked hubs for proper grease, not source of problem. Mm
A bolt associated with suspension failed, causing front wheel to come off.
Rear axle lock nut and pan cake washer failed and axle slid out with wheel still attached. This is the 2nd occurance in 2 years. First time vehicle was traveling at 10 mph, second time 55 mph.
Rear axle/locknut and pancake washer failed and the axle fell off with the wheel still attached.
Multiple rust spots on vehicle jeopardizing integrity of support structure. Metal used on sidewalls of frame is too thin.
