Recalls 3
Vehicle speed control: accelerator pedal
- What is wrong
- The coating used to protect the accelerator pedal shaft is incompatible with the bronze bushing through which the shaft passes. Over time, and in the presence of a corrosive environment (water, road salt), the shaft can corrode inside the bushing increasing the amount of friction between the rotating shaft and the stationary bushing.
- Risk
- A corroded accelerator pedal shaft can cause the engine throttle to bind and not fully return to idle when the operator's foot is removed from the accelerator pedal increasing the potential for a vehicle accident.
- Remedy
- Dealers will install a revised accelerator pedal and shaft assembly.
Recall number 96V049000 · Recall details
Fuel system, gasoline: delivery: hoses, lines/piping, and fittings
- What is wrong
- The passenger compartment is separated from the engine compartment by an insulated engine cover. The insulation inside this cover can rub against the fuel return hose resulting in a fuel leak. Additionally, a wiring harness can also wear through causing interruption to some electrical operations, including the fuel pump.
- Risk
- Fuel leaking inside the engine compartment can result in a fire when exposed to a source of ignition. Failure of the electric fuel pump can cause poor performance and possible stalling creating a road hazard which can result in an accident.
- Remedy
- Dealers will replace the rubber fuel line hose with a solid steel lines and route the line to provide one inch of clearance to the cover. Also, the wiring harness cover will be replaced and the wiring rerouted to gain sufficient clearance.
Recall number 94V162000 · Recall details
Fuel system, gasoline: delivery: hoses, lines/piping, and fittings
- What is wrong
- The oil pressure switch which controls the power to the electric fuel pump can fail. Failure is due to a missing rubber seal between the switch and the wiring harness. The missing seal allows contaminants to enter the switch causing it to fail in the open or closed position.
- Risk
- If the switch fails in the closed position, the pump will continue to run when the engine is off, draining the battery. If the switch fails in the open position it will cause poor performance and possibly stalling.
- Remedy
- Dealers will inspect the vehicles for the presence of the seal. If the seal is missing, the switch will be replaced and a new seal will be installed.
