Service brakes, hydraulic
Jaguar is recalling 14,551 my 2004 xj vehicles. A potential concern has been identified with the installation of a noise vibration and harshness (nvh) pad fitted to the under tray and its interaction with the rear under floor brake pipes, rear cross member brake pipes, and their unions.
Remedy: Dealers will remove the under tray at the rear of the vehicle and remove and discard the nvh pad fitted to the rear of the under tray.

What 2004 Jaguar XJ owners say
Speed control & acceleration

Accelerator and brake pedal are too close together causing me to depress both pedels at the same time when trying to stop car. Dealer advised me to take this complaint to another level since there are no remedies available.
Brakes
The contact owns a 2004 Jaguar XJ. The contact stated that while depressing the brake pedal, the brake pedal felt spongy and an excessive amount of force was needed to depress the brake pedal. The brake pedal almost went to the floorboard before the vehicle came to a stop, causing the braking distance to be extended. The message that the brake fluid level was low remained illuminated. There was brake fluid leaking from a fractured cross-member brake pipe. The vehicle was taken to a certified mechanic, who found that the underfloor tray was corroded, causing the floor to fracture. The vehicle was not repaired. The failure was associated with NHTSA Campaign Number: 09V144000 (Service Brakes, Hydraulic); however, the VIN was not included. The manufacturer was not informed of the failure. The failure mileage was approximately 128,000.
