While driving my 1997 Jaguar Xk8 on polaris parkway @50mph, the car lost total power. I had to weave out of the middle lane in order to reduce a potential accident. . The local Jaguar dealer tested and reported that the throttle body failed thus causing vehicle to lose all power. . . During the dealer test drive, the car also lost power on highway #670. . Due to the safety issue, Jaguar should make the necessary repairs. .

Tl-the contact owns a 1999 Jaguar Xk8. While driving at any speed, the vehicle would shift into limp home mode and it would not accelerate faster than 5 mph.

The current and failure mileage was 75,000.

I removed foot from accelerator and applied brake. Car surged forward. I shifted foot farther to left and continued brake application and car stopped. I discovered that brake and accelerator pedals too close together so that, when foot applied to brake, right side of foot can inadvertently press down on accelerator.

I have a 1998 Jaguar Xk8 convertible. Current mileage 37,334. Twice, while driving at 60 mph, the engine just cut out. After pulling to the side of the road and waiting several minutes I was able to restart the engine. The first time this happened, I attributed to possible a bad tank of gas on March 2006. After the second time on March 2007. I feared it had another cause. Just about that time I received from Jaguar a "service action" s-514 stating that there was a problem with closed throttle operation, and it sounded like my problem. I e-mailed them several times to ask about an authorized service facility to have it repaired. They referred me to customer service. A rep called to say I could only have it fixed on the mainland! that of course, would cost me few thousand dollars. I asked if it could be fixed by someone here locally at my cost. She said "we can't recommend that". Not helpful at all. My complaint, however, has more to do with how this problem is classified. This should be a "safety recall" not simply a service action. Both incidents put me and others in a very dangerous situation. Once I was fortunate enough to have no one directly behind me. The second time I caused several cars behind me to swerve off the road or skid into oncoming traffic. I was just lucky that no one was seriously injured or killed. I checked your site for complaints. This problem has been going on for years!!! apparently, I'm not the only one forced into a dangerous situation how is it possible that this is not considered a safety recall? by being a "service action" Jaguar can just ignore me. I believe they should make more of an effort to fix my car or help in finding someone who will. . . At their cost. Can they do this legally?.

I was recently made aware that an extremely dangerous condition that occurred with my 2001 vehicle was something that should have been prevented. It was considered a recall item on Jaguars in model years 1997- 1999 (Jaguar service action number: s514, subject: throttle closed position operation, reference: 13/05/04 303-s514v1). I experienced the same conditions described in the recall notice and could have easily, without exaggeration, been killed due to this engineering defect. Specifically my Jaguar Xk8 would display warning lights and messages while rapidly dropping to a speed of about 1 mile an hour and would go no faster. The messages indicated the following: restricted performance, failsafe engine mode, trac not available, asc not available. After the engine was shut off the messages would clear and the vehicle worked fine. This happened, luckily for me only when I was at a stop light or traveling very slowly (example: leaving the house). While driving to the dealer for the repair, this condition occurred 5 times including, for the first time, on the highway at a high rate of speed. The throttle body was replaced by the dealer at a cost to me of nearly $2,000. I contacted Jaguarã‚s customer service department last week to express my concerns and what I thought should happen: 1) this car should have been recalled and repaired; 2) when it wasn't and I explained the symptoms to the dealer, it should have been treated as a recall item then and I should have been advised to immediately stop driving the vehicle and to have it towed. I was told that today, March 5, 2007, that no action would be taken to inform others and that no refund would be forthcoming. I learned about this recall information from another service shop who stated that I was the third Jaguar Xk8 that he sent to dealer with this problem. Roadfly has notes from several people trying to solve this same problem. This is not an isolated incident.

:the contact stated while driving 20 mph, the engine stopped running due to a tensioner failure on the timing chain. The conditions were dry and sunny. There was no accident nor police report filed.

Consume received recall 99v138000 for the throttle body. Consumer took the vehicle to dealer, and the vehicle was taken for a test after installation of the throttle body, and the thermostat went out. Vehicle was destroyed, and the consumer was charged for the new parts. Dealer was instructed to replace the vehicle prior to making repairs to the throttle body.

While driving vehicle stalled. Driver tried to restart vehicle, but vehicle would not restart. Vehicle was towed to the dealer for inspection, and mechanic determined that throttle needed to be replaced due to a worn out shut off valve part.

Throttle position sensor contacts fail due to design flaw causing ecu to go into limp mode. Ecu unable to determine pedal position, causing incorrect fuel metering and incorrect shift pattern.
