One problem related to engine cooling system has been reported for the 1998 Jaguar XJ8. The most recently reported issues are listed below.
My 1998 Jaguar Xj8l keeps stalling at highway speeds, very very dangerous. I am almost in an accident on 95 everytime this happens. The dealer has said it is a dirty throttle that may be causing this, but even after servicing it just starts up again. . . After investigating here on the web I have found that this is a common problem that needs to be addressed. I believe this is what happened to me back on September 2004, when my engine just completely froze up on 95 and had to replace it at a cost of $15,874. 00. This need to be addressed and a recall should be posted for these vehicles before someone gets killed. I have a sneaky feeling that this is starting all over again with the engine stalling and now I only have 13,000 miles on my new engine. Please help!.
