1979 Jaguar XJ — Problems, Recalls & Complaints

EXCESSIVE FUEL VAPOR PRESSURE CAN OCCUR THAT, AFTER PROLONGED CYCLING, COULD WEAKEN THE FUEL TANK STRUCTURE.

Remedy: INSTALL A REVISED FUEL PURGE SYSTEM WHICH ELIMINATES EXCESSIVE VAPOR PRESSURE BUILD-UP.

THE EXHAUST DOWNPIPES INSTALLED ON THE INVOLVED VEHICLES MAY NOT PERMIT PROPER CLEARANCE BETWEEN THE DOWNPIPES AND THE STEERING COLUMN LOWER JOINTS. UPON MAKING A HARD FULL RIGHT TURN, THE EXHAUST DOWNPIPE AND STEERING COLUMN COULD COME INTO CONTACT WITH EACH OTHER. THIS COULD RESULT IN A LOSS OF STEERING CONTROL.

Remedy: DEALER WILL INSPECT AND, IF NECESSARY, REPLACE THE EXHAUST DOWNPIPE WITH ONE OF MODIFIED SHAPE, WITHOUT CHARGE TO OWNER.

THE SELECTOR QUADRANT SPIRAL RETAINING PIN MAY WORK ITS WAY OUT OF POSITION SO THAT THE VEHICLE COULD REMAIN IN GEAR WHEN SELECTOR LEVER IS MOVED INTO THE "PARK" POSITION.

Remedy: DEALER WILL SECURE SPIRAL PIN USING A RETAINING PIN TO PERMANENTLY LOCK IT IN POSITION.

THE IGNITION AMPLIFIER MAY CONTACT AND SCORE THE FUEL FILTER. OVER A PERIOD OF TIME, SCORING OF THE FILTER CAN CAUSE FUEL LEAKAGE.

Remedy: DEALER WILL INSPECT AND, IF NECESSARY, ADJUST FUEL FILTER BRACKETS AND REPLACE FILTER WITHOUT CHARGE TO OWNER.

ELECTRONICALLY CONTROLLED VALVES IN THE CRUISE CONTROL ACTUATOR MAY NOT FUNCTION PROPERLY DUE TO DIRT ENTERING THE VALVES.

Remedy: REPLACE CRUISE CONTROL ACTUATOR AND INSTALL ADDITIONAL VACUUM DUMP VALVE.
