Car Stall Problems of Jaguar XK8

Tl the contact owns a 1997 Jaguar Xk8 convertible. While driving 40 mph and slowing to make a right turn, the vehicle stalled without warning. The contact was able to restart the vehicle after approximately five minutes. The vehicle was taken to an independent mechanic where it was diagnosed that the throttle body needed to be replaced. The vehicle was repaired; however, the failure recurred. The contact stated that the failure was intermittent. Neither the dealer nor the manufacturer was notified of the failure. The approximate failure mileage was 142,000.

1998 Jaguar Xk8 has a history of stalling on the freeway at speeds of 55-60mph. This occurred twice (prior owner - 38,246 miles) - prior owner told by Jaguar that automobile had been repaired by replacing throttle. Same incident occurred at later. On-line information shows that several other 1998 Xk8 owners have the same issue that engine turns off without warning - the car has a design flaw. There has been recalls regarding the throttle. I do not understand why the nhtsb has not forced Jaguar to repair this 1998 Xk8. The model, 1998 Jaguar Xk8, has a design flaw and is a safety risk.

The vehicle, without any warning and instantaneously at speed limit in a freeway travel lane, ceased to operate. This happened on numerous occasions since first acquired with less than 4,000 miles use. Each time this caused the driver (my wife) to conduct an emergency procedure - hit the emergency flashers, shift to neutral, and restart the car while it was decelerating. The last time was on July 14, 2008. The power steering, power brakes, safety handling systems, and engine were inoperable. The vehicle was taken to an authorized Jaguar dealership where the problem was acknowledged, diagnosed, and ostensibly repaired. The repair was ineffective and within a few days of the first repair the vehicle failed in the same way again. The vehicle was taken a second time to the authorized Jaguar dealer where another repair was conducted. Following this repair the incident did not reoccur until July 14, 2008. That day, while at freeway speeds in a travel lane, the vehicle ceased operation with no warning once again. This time however it would not restart as stated above and the vehicle coasted to a small gore-point between two concrete toll booths while traffic avoided the vehicle to each side. The vehicle would not start from neutral, but had to be placed in park in order to restart. For the third time, the vehicle was taken to an authorized Jaguar dealership where the service technical attempted the Jaguar "service action". The procedure failed, the vehicle was totally disabled, and the car could not be started for two weeks. A Jaguar factory field employee and a mechanic from out of the area worked on it and now report that "everything is fine". They have reinstalled the defective electronic control unit and report that they are confident that this time there will be no more trouble of this nature. I do not share their confidence. I ask that NHTSA investigate this problem and assess the safety risk of the Jaguar cars "service action" procedure.

I purchased a used 1998 Jaguar Xk8 with 40000 miles in Nov 2004. It immediately started stalling at highway speeds. I took it to a local dealer in little rock arkansas, and thay told me that they could find nothing wrong with the car but charged me $1,600. 00 for service that was not necessary. Within weeks it again began dying at highway speeds and would not re-start without pulling off the road, which is at times impossible due to I-30 being under construction and having no shoulder or exits, only 6-foot concrete barriers on either side of the two lane highway. I was at the mercy of every driver behind me. This is a life threatening situation that Jaguar denies having any knowlege of. I have recently found hundreds of complaints on this issue with jag owners who have had the same problem. Ford has issued a field action that admits that the throttle-body is defective, but they're not fixing the cars in the u. S. , only in other countries. Please do something before someone is killed.

The vehicle stalled intermittently without warning. The gear shift failed to come out of park. Also the antenna and power mirror switch was replaced and the coolant light illuminated.

1997 Jaguar Xk8 suddenly stalls out completely during freeway driving. Other listings at NHTSA regarding this. Potentially fatal issue as the car cannot be steered off the road easily. No warning of failure - resulting in following traffic having to break lane suddenly to avoid the stalled jag. This is really serious stuff.

Vehicle has stalled 7 times in the last 20 months, dealer has attempted to correct problem on four occasions.

While driving approximately 60 mph on the highway, the vehicle stalled without any warning. Dealer replaced the throttle box, and the oxygen sensors, but the stalling continued.

Vehicle had to be flatbed to dalership numerous times due to not starting after stalling out in middle of traffic. Sometimes, vehicle could be restarted but would stall out. Was informed by mechanic would need a new engine and new controller box. Owner feels it was an electrical problem.
