The contact stated that while traveling 60 mph the vehicle started to shake and the rear driver side tire blew, causing a roll over crash. The contact sustained a concussion from the crash. The vehicle was destroyed. A police report was filed of the incident.
Driver seat is falling down in front win you stop. Look at some other bronco ii and thay have the same brake under the front seat in the pan. Went to the dealer and showed them and got no response.
Accelerator pedal stuck to floor, vehicle accelerated, resulting in loss of control/crash and injuries. Also, brakes failed and upon impact, seat belt failed to lock.
While driving applied the brakes and truck accelerated/locked up, causing the truck to hit a fence, that was the only way that the truck would stop.
While driving at approximately 30 mph vehicle caught on fire. Owner later called a tow truck and had the vehicle towed to an independent mechanic shop.
Consumer states that a person driving this vehicle experienced a roll over when another suv coming the other way, struck its side, the driver sustained severe brain trauma, also the passengers seat broke during the accident, causing the passenger to end up in the back seat, consumer requesting any possible recall…
The fiberglass all around my spare tire area is cracked because the support bracket is too small, not holding enough weight for the tire.
Car's shudder (a rapid on off on killswitchlike) has worsened. Yesterday this off time expanded to several seconds, and at higher speeds. At one time the engine died at 45mph. I was nearly rear ended as vehicle speed fell off rapidly. I escaped collision by executing a hard right off the street into a bank's lot exit.
