Limited data — recalls on file
NHTSA has just 5 complaints on file for the 1984 Jaguar XJS — too few to judge reliability from owner reports alone — but 3 recall campaigns apply to this year, so any used example should have its VIN checked for completed recall work.

Consequence
THIS CAN CAUSE FUEL TANK LEAKS WHICH, IN THE PRESENCE OFAN IGNITION SOURCE, COULD RESULT IN A VEHICLE FIRE.
Remedy
INSTALL A REVISED FUEL PURGE SYSTEM WHICH ELIMINATES EXCESSIVE VAPOR PRESSURE BUILD-UP.
Defect
ELECTRONICALLY CONTROLLED VALVES IN THE CRUISE CONTROL ACTUATOR MAY NOT FUNCTION PROPERLY DUE TO DIRT ENTERING THE VALVES.
Consequence
CRUISE CONTROL WOULD NOT DISENGAGE UNDER NORMAL OPERATINGCONDITIONS WHICH COULD RESULT IN LOSS OF CONTROL AND AN ACCIDENT.
Remedy
REPLACE CRUISE CONTROL ACTUATOR AND INSTALL ADDITIONAL VACUUM DUMP VALVE.
Defect
POSSIBLE FUEL LEAKAGE FROM THE ENGINE FUEL INJECTION SYSTEM, PARTICULARLY IN THE AREA OF THE HOSE/CLIP FITTINGS. CONSEQUENCE OF DEFECT: THE PRESENCE OF AN IGNITION SOURCE, WITH FUEL LEAKAGE, COULD RESULT IN AN ENGINE COMPARTMENT FIRE OR THE DESTRUCTION OF IGNITION DISTRIBUTOR CAP.
Remedy
A NEW FUEL DELIVERY SYSTEM DESIGNED TO ELIMINATE FUEL HOSE CLIPS WILL BE INSTALLED.

“FUEL TANK CRACKED CAUSING FUEL TO LEAK INTO VEHICLE WHICH MAY HAVE CAUSED A CRASH. THERE WAS RECALL FOR THIS DEFECT, BUT HAS BEEN REMEDIED YEARS AGO. HOWEVER, PROBLEM STILL EXISTS. PLEASE PROVIDE FURTHER INFORMATION. *AK”
The record is thin — 5 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 3 recalls should be verified as completed.
