Electrical system

7 reports2 crashes
“The contact's husband owned a 2011 Jaguar XJ. The contact stated that while her husband was attempting to park in a parking space and the brake pedal depressed, the vehicle independently accelerated. The contact attempted to decrease the vehicle's speed by going over a bump however the vehicle continued to independently accelerate. The brake pedal was depressed to the floorboard and then lifted his foot off the brake pedal resulting in a crash with a median. It was unknown if any warning lights were illuminated since the events occurred rapidly. The front air bag partially deployed upon impact. The contact's husband was taken to the hospital by an ambulance where he was treated for both a neck sprain and a back sprain. A police report was filed. The vehicle was towed to an independent tow yard and was later determined to be a total loss. Upon investigation, the contact discovered NHTSA Campaign Number: 20V557000(Air Bags) which was linked to the failure. The dealer was notified of the failure but offered no assistance. The manufacturer was not notified of the failure. The failure mileage was approximately 75,000.”
