JAGUAR issued a recall on the XJ model

On certain vehicles, the front wiper arm to spindle fixings may suffer torque relaxation. Torque relaxation of the securing nut could potentially result in loss of wiper arm synchronization, which can cause clash of the arms. If the wiper arms lose synchronization and clash, they could detach from the vehicle, and in certain circumstances, the driver's forward vision could be impaired, which may increase the risk of a crash. Furthermore, in this condition, the requirements of Canada Motor Vehicle Safety Standard 104 will not be fully met. Correction: Dealers will ensure the wiper arm is fitted securely onto the spindle and the securing nut is tightened to the correct torque.
