On Saturday, May 12, I was pulling into a parking space at the post office. The car suddenly lurched forward and my brakes were not responsive, my car slammed into the curb. Had there been a pedestrian crossing the parking lot at that time, the results could have been fatal. I called Jaguar to se if this was a known problem, I was told it was not. However, there are several reports of this problem found on the Internet. I have since labeled my car a 'killing machine' and I know each time that I drive it may be my last.
