The 1978 Audi 5000 has 3 recalls, all involving the automatic transmission and conditions that can cause the driver to lose control of the vehicle's acceleration or braking.
All three recalls affect automatic transmission models and share a common theme: unintended acceleration and throttle control. The floor mat in the driver's compartment can slide forward and catch on the accelerator pedal's vibration damper, holding the throttle partially open when the driver lifts off the gas. Separately, when shifting from Park into Drive or Reverse, the vehicle may accelerate on its own without any pedal input, creating a crash risk before the driver can react. There is also a pedal geometry concern: the gas and brake pedals sit close enough in height that a driver may press both at the same time, which can result in the brakes fighting against an open throttle or the driver losing directional control of the vehicle.
