I have filed this compliant a couple of weeks ago, but it doesn't appear in the search, so I'm filing it again. I believe Jaguar has a serious problem that should be addressed by a mandatory recall. My 2000 XJ8 has been having surging problems for years and has gone into limp mode on numerous occasions...usually on the interstate...where I have narrowly missed causing serious accidents. The local Jaguar dealer had the car twice, each time for approximately one year. Each time they said it needed a throttle body. After the third throttle body, I called Jaguar in New Jersey and they contacted the dealership and walked them through bench testing the throttle body off the car. Turns out there was never a throttle body problem. So after three throttle bodies, the replacements at $2400 each, the Jaguar dealer said they couldn't fix the car. I then sent it to four other mechanic shops. Most had it for at least six months. Each admitted the problem existed, but none could fix it. The ECM and tcms were changed, spark plug wires, spark plugs, ac component, all grounds checked, harness checked, etc., etc., etc. Keep in mind the car only has 37000 miles. Finally, while another mechanic was trying to find the problem, the engine locked. The car was towed to another mechanic, who opened the engine and found the timing chain tensioners had allowed the chain to jump two teeth. Apparently, the tensioner problem is well know to Jaguar and its dealerships. Even tech bulletins have been sent, but owners were never notified of the problem directly. Now that I have searched the forums, it is apparent the problem is prevalent. I'm lucky I was not killed in the car. I now have to install a new engine due to this known problem. Maybe if enough people are killed or maimed, we will finally see some action to force Jaguar to fix their obvious design problem resulting from their effort to increase their profits.

Jaguar 2000 xjr: While driving vehicle would suddenly display warning message that traction control / asc was not available and would go into a failsafe engine mode. Engine would then run very roughly and would not accelerate past 5-10mph. Mechanic diagnosed a fault code of P0121 which is addressed as a known Jaguar technical service bulletin for a "mismatched" connector to the throttle body. Internet research reveals that this is a very common problem experienced by many Jaguar owners that is known by Jaguar and constitutes a safety hazard. Jaguar knows that it mismatched gold and tin plated throttle body connectors and advised its repair tech's to replace only if customer complains! how will a customer know such a problem exists until it happens and it will happen eventually. Anything that may suddenly and without warning affect a vehicle's ability to accelerate is a major safety hazard. Jaguar should have and must issue a full recall of the affected vehicles before somebody gets catastrophically injured and/or killed. It costs in excess of $450+ to fix this known problem and Jaguar is allowing consumers to drive unsafe vehicles that may fail at the worst time. What would have happened if I was making a left turn and it failed at the wrong time and got broadsided with my wife or children inside?

The contact states 2000, Jaguar xjr was experiencing a loss of power. The vehicle has undergone diagnostic testing. The service dealer could not duplicate the problem. The vehicle started out with intermittent power difficulties, but it became too frequent. The vehicle jerked sometimes on initial acceleration from a complete stop and automatically changed gears. There have been several near misses on the interstate as a result of not being able to accelerate quickly. Updated 3/17/2006 -
