Just google "Jaguar throttle body" and see how many problems customers are having. My 2005 xj8lwb with less than 60,000 miles experienced a throttle body failure while traveling on the interstate. I lost power as the engine went to idle speed and an "engine fault" message alerted me that there was a problem. Fortunately, I was able to make it to the shoulder and creep down an exit, where I was able to find a service station. I turned the engine ignition off and waited for 15 seconds and restarted the engine, the fault message was gone and the engine had power again. I was able to make it home without another incident. We all would have been dead if an 18 wheeler was behind us when the engine lost power. Last Friday, I had several episodes with the "engine fault" and loss of power, but made it to a Jaguar dealership safely, but shaken. They put the vehicle on the computer and announced the code that relates to the throttle body and figured the repairs to be $1,100 and that I could pick up the car today on August 23, 2010. Over the weekend I searched the internet and saw the vast numbers of people having the same problem. Some people reported accidents. Please look into this problem before someone is killed. Jaguar has recalled earlier models with throttle body problems, but refuses to recognize this problem on the 2004 and later models as of today. From my discussions with Jaguar usa it does not appear that they will own up to the problem unless forced to. Hopefully this where the NHTSA comes in.
