On the 2006 Jaguar XK, multiple 2006 complaints describe the vehicle accelerating when the brake pedal was applied, including incidents while exiting highways, approaching red lights, and parking. Several reports resulted in crashes and injuries, and the pattern aligns with Jaguar's recall for incorrectly assembled accelerator pedal arms that could reduce brake/accelerator clearance.
Inspect the accelerator pedal assembly first and confirm recall 05V162000 has been completed. Diagnose for pedal interference, sticking pedal travel, and electronic throttle/brake override behavior; repair typically involves replacing the accelerator pedal assembly and verifying pedal spacing and throttle adaptation. If the recall remedy is incomplete or ineffective, further diagnosis of the throttle actuator and pedal position circuits may be needed.

On the 2006 Jaguar XK, airbag complaints on 2006 XK/XKR models include repeated airbag warning lamp illumination and a failed passenger-seat sensor that could prevent proper airbag deployment. One owner reported multiple unsuccessful repair attempts for recurring airbag light faults, suggesting an intermittent seat sensor or connector issue rather than a one-time warning.
Inspect the passenger seat occupancy sensor mat, seat wiring harness, and under-seat connectors for high resistance or intermittent contact. Repairs typically involve replacing the occupancy sensor or seat harness and then clearing/restoring the supplemental restraint system calibration. Repeated warning-light returns usually mean the sensor mat or connector needs replacement rather than another temporary connection repair.

On the 2006 Jaguar XK, at least one complaint tied to the speed-control group describes the vehicle entering limp mode and slowing abruptly in traffic, creating a hazard with surrounding vehicles. While fewer reports are available than for unintended acceleration, the complaint indicates a real drivability pattern involving electronic powertrain protection and reduced-throttle operation.
Scan the PCM and throttle control system for stored faults, then inspect the electronic throttle body, accelerator pedal signals, battery voltage stability, and related wiring. Repairs can range from software updates and connector repair to throttle body or pedal assembly replacement depending on the fault source. Because limp mode can overlap with throttle-control issues, a full ETC diagnostic is needed before replacing parts.

VEHICLE SPEED CONTROL:ACCELERATOR PEDAL
ON CERTAIN PASSENGER VEHICLES, THE ACCELERATOR PEDAL ARMS WERE INCORRECTLY ASSEMBLED BY THE SUPPLIER. THE CLEARANCE BETWEEN THE ACCELERATOR PEDAL AND THE BRAKE PEDAL MAY BE REDUCED. THIS CONDITION CAN INCREASE THE RISK OF BOTH PEDALS BEING OPERATED AT THE SAME TIME BY THE DRIVER.
