Jaguar—XJ—Wiper Arm Durability
What are the defects?
The manufacturing process to attach the wiper arm to the spindle was insufficiently controlled such that the specified torque was imparted on the fixing.
What are the hazards?
Through torque relaxation, the securing nut could become loose, allowing the wiper arms to lose synchronisation, clash and potentially detach from their spindles.
What should consumers do?
Contact your authorised Jaguar dealership to have the wiper arm inspected and if necessery re-torqued.
