Limited data — recalls on file
NHTSA has just 0 complaints on file for the 1978 Jaguar XJ6 — 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.

NCAP overall
3 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
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.
Defect
UNDER A COMBINATION OF CIRCUMSTANCES IN COLD WEATHER, ICING MAY PREVENT RETURN OF THE THROTTLE BUTTERFLY TO THE IDLE POSITION.
Remedy
THE DEALER WILL FIT COOLANT HEATED THROTTLE BODIES ON ALL VEHICLES AT NO COST TO OWNERS.
Defect
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 record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 3 recalls should be verified as completed.
Yes — NHTSA lists 3 recall campaigns affecting the 1978 Jaguar XJ6. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
