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.

Common Symptoms

  • Airbag warning light stays on or returns repeatedly
  • Passenger airbag sensor failure message
  • Concern that passenger airbags may not deploy in a crash
  • Multiple repair attempts for the same SRS warning

How to Fix

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.

Owner tips & cautions

  • TipIf the airbag light is on, treat the SRS as compromised and scan it with Jaguar-capable diagnostics rather than clearing codes blindly.
  • TipCheck under-seat connectors for looseness or corrosion before replacing major components, but recurring faults usually need a sensor repair.
Typical repair cost:$250 - $1,200

On the 2006 Jaguar XK, nHTSA recall 05V162000 covers 659 model-year 2006 Jaguar XK vehicles. Some accelerator pedal arms were incorrectly assembled, reducing clearance between the accelerator and brake pedals. This could allow both pedals to be operated at the same time, and the accelerator pedal could be held down by the pedal stop assembly, increasing crash risk.

Common Symptoms

  • Reduced clearance between accelerator and brake pedals
  • Accelerator pedal may be held down by the pedal stop assembly

How to Fix

Check the VIN and recall-completion record. Jaguar dealers were instructed to inspect the accelerator pedal assembly and replace it free of charge if the affected condition was present.

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.

Common Symptoms

  • Vehicle enters limp-home mode
  • Sudden loss of power on the highway
  • Car slows dangerously with traffic behind
  • Reduced throttle response

How to Fix

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.

Owner tips & cautions

  • TipCheck battery and charging-system voltage first, since low voltage can trigger erratic electronic throttle behavior and limp mode.
  • TipUse a Jaguar-capable scan tool to read manufacturer-specific throttle and PCM faults before replacing parts.
Typical repair cost:$150 - $1,200

On the 2006-2014 Jaguar XK, the rear driveshaft (propshaft) on the X150 XK uses a bonded rubber flexible coupling — the 'rubber doughnut' or Jurid coupling — that perishes and splits with age and heat. Unlike earlier Jaguars where the coupling was a replaceable item, the X150 propshaft was progressively lightened and Jaguar does NOT list the rubber disc as a separate service part, so an official repair requires a complete driveshaft assembly. As the rubber cracks the shaft goes out of balance, producing vibration and eventually a clunk under load; a fully separated coupling can strand the car. Owners and independent Jaguar specialists have successfully cross-referenced/sourced the coupling separately (S-Type/X350 lineage; aftermarket suppliers now stock an X150 Jurid coupling).

Common Symptoms

  • Vibration through the floor that worsens with speed
  • Clunk or shudder on acceleration or when taking up drive
  • Visible cracks or splitting in the rubber coupling disc
  • Driveline rumble at cruise

How to Fix

Inspect the rubber coupling for cracking/splitting at every service. Accepted repairs are fitting a separately-sourced/cross-referenced Jurid coupling (available from independent Jaguar parts specialists) or replacing the complete propshaft assembly. Check and balance the shaft and inspect the center support bearing at the same time.

Typical repair cost:$300 - $1,800
