Recalls
2 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Speed control / throttle Vehicle recall #90V177000 · 1990 · 165,000 vehicles
What's wrong: Malfunction of fuel injection system throttle postition sensor could cause intermittent high engine idle speed immediately after starting engine.
Why it matters: High engine idle when car is first placed in gear couldresult in unexpected acceleration.
The fix: Replace throttle position sensors with sensors that would send correct signals to the fuel injection system.
Brakes (hydraulic) Vehicle recall #98V005000 · 1998 · 293,369 vehicles
What's wrong: The front disc brake rotors can experience severe corrosion if operated for an extensive period in the "salt belt." if the rotors are not replaced, the corrosion can eventually compromise the structural integrity of the stamped steel center hub section of the rotor.
Why it matters: The reduced strength can allow the cast iron wear surface to separate from the hub, reducing the brake effectiveness of the vehicle.
The fix: Dealers will replace these rotors with rotors that are coated with a corrosion protection.
