Customer Question

I have a 2004 Jaguar X-type 3.0 with an automatic transmission. On several occasions the car will accelerate when the brakes are applied at slow speeds. After the first time it happened, I made sure I was not pressing the gas pedal as well. The other day, I was pulling the car up to the garage and applied the brakes when it accelerated again on its own. I stepped on the brakes harder but the car went right into the garage door. I have been researching this problem tirelessly and have called several dealerships. All say they have never heard of this problem, which is curious because there are several claims about this problem on the National Highway Traffic Safety Administration's website. Other reports say that they have rear ended cars at stop lights and in parking lots. Everyone can claim that it is driver error and that both pedals are being depressed, but I am a mechanic myself and I have done enough digging to realize that this is a serious problem. My only guess is that there is an electrical problem with the throttle position sensor or the whole throttle body. Any help would be greatly appreciate, as I will not drive the car until this problem is solved. If I can't solve this mystery soon, the car will go on the market.

I have tried calling every Jaguar dealership in my area and have talked to several service managers in person. None have been any help in solving this problem.

Hello again Jack - Thank you for your reply -

This is by no means an unknown issue with these vehilces - but what the actual cause is as yet , Jaguar have not come up with a definitive answer..

I do know however that on the Uk models there was an issue with the throttle pedal stop - and the accelerator pedal itself becoming distorted in use - meaning that the pedal would actually stick down in use - and that would cause such problems - ie, accelerator pedal actually sticking and causing the engine to race when braking - because it was still operating the TPS - throttle sensor. I don't know whether you are aware of that issue or have had that checked / looked at at ll - it is I mention, a known issue here..

Other than that , If that is not whats causing it - it can only be a fault in the Tps circuit or throttle body , or Ecm fault. All of which would need proper checking through.

Something else that I feel may be the cause ( other than the above ) would be the software in the Ecu - but until Jaguar identified that as a fault / the cause, there is nothing that can be done - because they would have to ID that for sure as the cause - and then write new software for the ecu..

Let me know if you need anything else on this -
