“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.”
NHTSA complaint #10040883, filed 2003-09, 66,800 miles“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. …”
NHTSA complaint #10211798, filed 2007-12, 60,895 miles“The timing chain tensioners for my 1998 Jaguar XJ8L have disintegrated in the engine. Luckily we found the pieces in the oil change before the timing chain broke and caused further damage to the engine. But this is causing me to have to rebuild this area of the engine. Jaguar has all but admitted installing faulty parts by revising this part twice, once with a reinforced plastic tensioner with a spring, and finally with a metal tensioner that will not break or crack under the stress of tensioning the timing chain.”
NHTSA complaint #10116597, filed 2005-04, 105,000 miles“The vehicles engine stalled without warning while driving at approximately 60 MPH on a 4-lane limited access highway. The instrument panel display read engine stalled . My wife was driving and she was able to coast the car to the side of the road to a safe stop. Fortunately there was no other traffic in the immediate vicinity. The engine restarted once the ignition was turned off and back on. We have experienced similar intermittent stalling over the last year or so, but never at highway speeds. …”
NHTSA complaint #10078731, filed 2004-06, 67,800 miles“My 1998 Jaguar XJ8L continually stalls at highway speed...Jaguar knows about the problem and uses it as a source of cash flow, charging several hundred dollars each 10,000 miles to remedy the situation through replacement of the throttle body or cleaning of the breather ports...this car should be recalled.”
