I searched the forum and didn't find any mention of this so I thought I'd start a new thread in case others who are affected haven't received a notice. If there is a current thread on this issue, I apologize for the duplication.

I received a letter dated December 12, 2014 from Jaguar Land Rover North America with a subject heading of Safety Recall J048: Brake Pipe Torque Integrity.

The letter states that certain underbody brake pipe unions may not be to the correct torque specification. Low torque at the underbody brake pipe unions can lead to a loss of mechanical integrity of the braking system. This can result in extended brake pedal travel combined with reduced braking performance in the corresponding brake circuit...In the event of both braking circuits losing integrity at the same time, complete loss of service brakes will occur, potentially causing a vehicle crash.

The letter advises to contact your authorized Jaguar retailer at your earliest convenience to schedule an appointment to have Recall Action J048 completed on your vehicle.
