Oct 26, 2022SuspensionEngineCrash1 injury

Under heavy breaking the rear wheels of my vehicle lifted off of the pavement. This loss of traction and shift in weight resulted in a head on collision with a vehicle in the opposite lane of traffic. After the accident I discover that the suspension for my vehicle was incorrect to the level that FCA released a TSB regarding the issue. The suspension that was equipped with the vehicle was designed for the gasoline motor and the weight associated with that motor. My vehicle has the diesel motor (approximately 600lbs heavier) along with factory equipped steel bumpers adding additional weight. This factory design failure created a vehicle that could not perform as designed and as I found out via an automotive accident, a vehicle that under heavy breaking can lift its rear wheels off of the ground.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Jeep Gladiator verdict →
