What owners wrote

When brakes applied in panic stop, pedal goes to floor. This allows inadvertant contact with accelerator most of the times I tried to duplicate this after the accident using right foot to brake. Precise placement of right foot is necessary for me to prevent this( I have to look down at my foot to get it where it won't hit the accelerator in this situation).

April 2001 CrashInjury

We parked at a convenience store and upon stopping to park the ABS pump started whining and would not shut off even after turning off the engine. Service manager at jim fuoco motors in grand junction, colorado disconnected the wires to the ABS relay system under the frame of the truck. He said the ABS relay module under the frame is faulty and that it would cost over $1000.00 for parts and labor to replace due to faulty diodes on the system.
