Everything below is an owner-reported complaint submitted to NHTSA about the 2006 Jaguar Xj, grouped by the component NHTSA recorded on the report.

WHILE BEING STOPPED AT A STOP SIGN WITH FOOT ON BRAKE THE CAR SUDDENLY ACCELERATES. THIS IS THE 5TH TIME THIS HAS HAPPENED, ONE TIME RESULTING IN AN ACCIDENT. I HAVE CALLED JAGUAR AND THEY BLAME THE DRIVER. I REPLACED THE THROTTLE WHICH CONTAINED THE SAME TPS SENSOR THAT HAS PLAGUED TOYOTAS. I AM GOING TO REPLACE THE PEDAL SENSOR AND IF THAT DOESN'T WORK I GUESS I WILL SELL THE CAR. EACH TIME THIS HAPPENS THE CAR IS STOPPED WITH THE RIGHT FOOT ON THE BRAKE. THE ACCIDENT WAS AT A SCHOOL WAITING IN A LINE OF STOPPED VEHICLES WAITING TO PICKUP STUDENTS.

Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
DT*: THE CONTACT STATED WHILE STOPPED AT A TRAFFIC LIGHT, THERE WAS A RATTLING AND GRUMBLING NOISE COMING FROM UNDER THE HOOD. SHORTLY THEREAFTER, THE POWER STEERING FAILED, AND HEAT WAS FELT COMING FROM THE DASHBOARD AND UNDER THE FLOOR ON THE DRIVER SIDE OF THE VEHICLE. THE VEHICLE WAS ABLE TO BE COASTED NEAR A PARKING LOT, AND DRIVEN INTO A PARKING SPACE. EXCESSIVE FORCE WAS REQUIRED TO TURN THE STEERING WHEEL, WHICH WAS ACCOMPANIED BY GRINDING NOISES. THE VEHICLE WAS TAKEN TO A SERVICE DEALER, WHO DETERMINED THAT THE MOUNTING HOLES IN THE SIDE OF THE ENGINE BLOCK USED FOR MOUNTING THE BRACKETS THAT HELD THE POWER STEERING PUMP ONTO THE ENGINE WERE NOT DRILLED PROPERLY. THIS CAUSED THE POWER STEERING PUMP TO DETACH, WHICH, WHILE FLOATING AROUND UNDER THE HOOD, CAUSED OTHER COMPONENTS TO DETACH. THE DEALER ATTEMPTED TO REPLACE THE AFFECTED COMPONENTS, HOWEVER THE MOUNTING HOLES DID NOT LINE UP, PREVENTING ANYTHING FROM BEING REPLACED. THE ENTIRE ENGINE WAS REPLACED TO CORRECT THE PROBLEM.*AK
