While accelerating to change lanes my vehicle went into wide open throttle. Despite removing my foot from the accelerator and slamming on the brakes the car could only be slowed to 40 mph. Hit the ignition switch which shut the vehicle down including lights. Appeared I would be rear ended therefore hit ignition and vehicle restarted with car still stuck in wot with foot off accelerator. With engine screaming and right foot fully on brake only able to hold car down to 40 mph. Hit ignition again which shut car down but once again following car about to rear end me and therefore once again hit the ignition with same result with car racing forward at wide open throttle despite no engagement of the accelerator. This time after holding the vehicle to about 40 mph with full pressure on the brake with my right foot, and the engine at wide open throttle, all cars had cleared out of the way. I therefore hit the ignition switch which shut down the vehicle. This time I brought the vehicle to a full stop. I then put the car in neutral (up until this time it had been in drive) and pushed the ignition on the car and it started at normal RPM. I then shifted into drive and the engine remained at idle speed. I then, at idle speed, traveled two blocks to my house. The smell of the burning brake pads was terrible. The next morning I had the vehicle transported on a flat bed truck to the local Jaguar dealer where the vehicle remains to this date. This all transpired over approximately 300-400 yards over a number of seconds. There was nothing on the floor or in the driving compartment that interfered with the accelerator or brake.

My Jaguar Xk 2007's accelerator pedal got stuck in the on position. I was traveling at approximately 10-20 miles on hour when I punched the gas pedal to about 60 miles an hour. When I released the gas pedal the acceleration continued. I then applied the brake and the car continued to accelerate. I then pushed the brake to the floor and shifted into sports mode and downshifted. At some point the accelerator must of disengaged as I was able to stop at the approaching intersection. Thank god, no one was hurt and I did not have to crash the car to stop. I subsequently had the car towed to the dealership where I bought the car only 5 weeks ago. They have had the car now for 3 days and have not given me any information about why this occurred.

The contact owns a 2007 Jaguar Xk convertible. While approaching a stop sign, the contact applied the brakes. The vehicle lunged forward instead of stopping. The brake pedal was depressed, but the vehicle kept moving forward at less than 2 mph. The vehicle did not come to a complete stop until it was approximately three feet into the intersection. The dealer stated that the issue was common and to continue driving the vehicle. He was advised to call back if the failure recurred. The vehicle worked normally for approximately 3,000 miles before the failure recurred. In this incident, the vehicle lunged forward and stopped approximately two inches from the preceding vehicle. The vehicle was towed to the dealer. They kept the vehicle for approximately 24 hours, but were unable to find any failures. The vehicle was towed back to the contact's residence; however, he is scared to drive it because the failure could recur. The failure mileage was 2,000 and current mileage was 5,000.

In the evening of 10/12/2006, within one day of driving a newly purchased 2007 Jaguar Xk, upon starting, the vehicle raced independently between 6 and 8,000 rpms uncontrollably. This "runaway" car event could only be ceased by shutting the car down. The vehicle was returned to the Jaguar dealership immediately the next morning with details of the occurrence. On 10/13/2006, the service manager at crown Jaguar, john schnepp indicated that he had reported the incident to Jaguar and had been informed by Jaguar that the vehicle was released with defective software and that there had been at least two other dealerships that had reported the problem already. He indicated that he was instructed to upgrade the onboard software for the purchased vehicle to the most current release. We asked what were they going to do with the other 6 or more other vehicles that they had in inventory. The service manager stated "...nothing unless they exhibit the same problem". we believe that this type of defect is not only serious enough to warrant a comprehensive review of his vehicles in inventory, but also warrants a manufacturer recall. A runaway vehicle could result in not only death or injury to a driver and passenger(s), but also pedestrians. This event was reported in the am on 10/13/2006 via phone to gregory magno at the office of defect investigation at NHTSA. Mr. Magno instructed us to report this defect via this web site.
