“Our 1999 Jaguar XJ8 has had numerous throttle body failures. It has been replaced by Jaguar and I have had to have it replaced twice. The problem with failure is that it causes a stability control failure which causes the car to be uncontrollable. In fact, my wife hit the edge of our garage entrance way do to it;s failure. I have contacted Jaguar on several occasions by letter, email and phone and they appear to be unconcerned and suggest that I continue to replace the throttle body once it goes bad. This is a real safety issue and requires the attention of your office.”
