The rear differential seal failed due to faulty manufacturing process wherein contaminated "lifetime" differential fluid was sealed into the differential housing causing excessive and premature pinion gear wear. This wear results in movement of the half shafts and the destruction of the differential seals. In order to remedy the situation an entire "new" differential must be installed. Simply ordering replacement seals and pinion gears will not suffice as the differential design was changed and the new components are of a different size, which results in requiring complete replacement of the rear differential at a cost of anywhere from $6200 - $8900, according to Jaguar dealerships. Jaguar is fully aware of this issue and have issued many tsb regarding same; however, they failed to take preventive action on tens of thousands of vehicles, many of which did not show symptoms of failure until after the manufacturer's warranty expires, resulting in hefty bills to unsuspecting owners.

While in the act of parking my father N law's car at the mall. I began to pull the car forward after a complete stop with my foot covering and applying the brake as another car began to pass in front of me. His 2009 Jaguar xfl surge and accelerated violently while the brakes were applied. Although this action didn't cause any accident or injury to anyone nor property damage. This occurrence was not the first while driving his car during my vacation in puerto rico. I'm writing to make others aware of the unsolicited acceleration problem this car has for fear of not just my safety and my family's safety but other consumers who might have purchased this car and are experiencing the same problem.

Faulty transmission.....the vehicle will not engage in drive. Each time the vehicle comes to a stop the vehicle will shift into neutral. You will then have to turn the vehicle off and back on to go forward. But when the vehicle comes to stop the vehicle shifts out of gear again. A new trans is needed due to the 3rd and 4th gears no engaging. The vehicle is less than five years old, although it has over 140K miles. This seems to be a recurring theme with the Xf model. This vehicle has always been serviced at a Jaguar dealer and for the vehicle to require a new transmission is very saddening. How does a luxury brand fail so much with the powertrain.

Began noticing a small whine in the differential, more obvious at low speed. Level of noise increased rapidly. Called dealer for an appointment 10/22/12 saw them that day and they verified the problem. Called Jaguar for authorization. Notified by Jaguar on 10/23/12 full authorization to replace the entire differential. Dealer advises an anticipated two day delivery time for replacement. Note: Completely satisfied that the dealer was helpful in such rapid authorization and turn around of replacement parts.my understanding is that usually a diff. Fluid analysis and "other remedies" are suggested prior to a major component replacement. I anticipate receiving the car back Friday the 26th, or the following Monday. They also notified me of a tail light recall which had not been done, which I had not been advised of by Jaguar.

I was driving in a parking lot and came to a stop but the car then accelerated and I had brake hard to hold the car back. I put the car into park. When I attempted to put the car into gear again, I could not move the shifter. I turned the car off and restarted it, and the car ran fine the rest of the evening. The next day, I was again in a parking lot and as I try to park, the engine accelerates wildly. I was able to hold the car with the brakes and put it into park. Once in park, the engine continued to rev. The shifter was now stuck. I tapped the shifter and that allowed me to shift the car and the engine went to normal operation. As of 12/11, the problem has not happened again. I will be taking the car to my dealer for diagnosis.
