2004 Jaguar XJ8 Owner Comments

problem #5

XJ8 8-cyl

  • Automatic transmission
  • miles


While stopped at a red light, foot on brake, shift in drive, vehicle went into very high rate of acceleration and lunged uncontrollably forward. Luckily there was no vehicle in front of me as I would have crashed into it. I notified the dealer and he referred me to a local dealer. The vehicle was inspected and I was assured that they found nothing wrong. This was a very scary situation and the manufacturer should seriously look into the matter.

This Jaguar 2004 XJ8 has been subject to 6 unintended acceleratons over a period of half a year including two in the dealer's shop. When in traffic or close quarters it has been necessary to place the shifter in neutral or reverse to control the acceleration. The dealer has had the car in his shop on three occasions. On the first occasion nothing was found. On the second occasion it was said that the fuel pump or its wiring harness were faulty and were replaced. On the present occasion it was thought that possibly this was a transmission problem. There have been mutiple episode and so only the last one is mentioned below.

2004, Jaguar, XJ8. Vehicle had to have the brakes and transmission replaced. Also, vehicle needed a new starter because the key will not come out of the ignition. After vehicle was taken to the dealership the catalytic converter made a popping noise. There were no other problems with the vehicle to the best of the consumers knowledge. Consumer felt that the mechanics working on vehicle were guessing as to the cause of the problem without solving the problem, consumer took vehicle back to the dealer 12 times since purchasing vehicle on June 25, 2005.

Problems with 2004 Jaguar XJ8 transmission. Transmission fluid was leaking due to a faulty output flange and seal. The transmission also leaked. The consumer researched the NHTSA website and found two recall. One was for the automatic transmission and the other one was for the frontal air bags. The consumer would like to know if her vehicle is part of or potentially could be part of the safety recall.
