The 1978 Jaguar XJ6 has 3 recalls, the most serious being an exhaust pipe that sits too close to the steering column coupling and can restrict steering movement, reducing the driver's ability to steer the vehicle.
A second control issue involves the throttle valve, which can ice up and stick partially open in temperatures at or below -10°C, leaving the engine unable to return to idle when cruising. The third recall covers a poorly grounded engine control harness that causes the fuel mixture to run too rich, which disrupts idle quality and pushes exhaust emissions above federal limits.
