A concern has been identified with the fitting process used in vehicle manufacture in relation to both rear seat belt D-loops on a number of 2009MY Jaguar XF vehicles. A minority of vehicles built up until VIN R22438 may have had seat belt D-loops fitted where the D-loops may not freely rotate. The seat belt may not run freely when the rear seat belts are being pulled out and, should a vehicle suffer a moderate to heavy frontal impact, the rear seat occupants may not be fully restrained.
