1998: “My 1998 Jaguar XJ8L stalled at high speed (70 MPH) on the freeway for the third time in the last six month with no warning. This cause me to have very little control over my car. I was able to stop the car and restart with no problem. I checked an internet site which has a forum documenting this problem. This is a serious problem on the freeway. Very scary.”

1999: “My 99 XJ8L Jaguar wouldn't start and I took it to a mechanic--he said 4 of my 8 cylinders stopped working and I needed a new engine.
