What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2006 Jaguar Xj Sedan, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
WHILE STOPPED IN THE ROAD WAITING FOR ANOTHER CAR. WITH FOOT ON BRAKE, THE CAR SUDDENLY GOES FULL THROTTLE. DRIVER HAS BOTH FEET APPLIED ON THE BRAKE AND THE CAR STILL MOVES FORWARD BURNING RUBBER, AND THEN AFTER A FEW SECONDS IT GOES BACK TO IDLE. THE CAR DOES THIS ONCE OR TWICE A YEAR, THE LAST TIME DOING DAMAGE TO A CAR IN FRONT OF IT. THIS IS THE FIFTH TIME THIS HAS HAPPENED. THE CAR IS IDLING NORMALLY WITH THE RIGHT FOOT ON THE BRAKE AND IT WILL JUST GO FULL THROTTLE ALL BY ITSELF. IT HAS HAPPENED ENOUGH THAT WE KNOW WE DO NOT HAVE BOTH THE BRAKE AND THE GAS PEDAL DEPRESSED. FROM DOING ONLINE RESEARCH I BELIEVE JAGUAR AND TOYOTA / LEXUS USED THE SAME SYSTEM FOR CONTROLLING ACCELERATION. I REPLACED THE THROTTLE BODY AFTER THE FENDER BENDER, IT EVIDENTLY DID NOT HELP.
FUEL TANK LEAK OF UNKNOWN ORIGIN CONSIDERED TO BE A HAZARDOUS CONDITION BUT WITH NO PLANS FOR REPAIR. CONSUMERS HAVE NOT BEEN INFORMED BY COMPANY. COMPANY KNOWS ABOUT PROBLEM. *JB
