The 1989 Ford Thunderbird has two recalls, the more serious being a rear suspension knuckle that can develop fatigue cracks over high mileage and eventually fracture, causing the rear suspension at that wheel to collapse and the driver to lose control of the vehicle.
The second recall involves the daytime running light module, which can malfunction and cause the running lights to dim, flicker, or shut off entirely while driving, or in some cases remain on after the ignition is turned off.
