“While traveling on the freeway at speed of approx. 60 miles per hour the vehicle lost the ability to accelerate and coasted to a stop. Fortunately I was able to pull over and restart the car. The loss of power resulted in a very dangerous situation on one occasion as I was stuck between a cement truck in front and a car carrier to the rear. I definitely feared for my life. After the third event I contacted rusnak Jaguar in pasadena and they told me the problem was due to carbon buildup in the throttle body and the solution is to remove the throttle body and clean and readjust. …”

That is a very dangerous situation to be on an interstate traveling at a speed of 50 and above having to drift across lanes with absolutely no power. As of this past weekend, I started the car, the airbag light would not go off. The next day, the car was making a horrible noise and once again the airbag light was on. The noise sounded as if something was loose underneath the hood. …”
