Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

I was accelerating away from traffic lights and the throttle jammed open. I had to switch into neutral to reduce the revs and bring the car under control.

Problem: Automatic speed limiter malfunction while traveling at 69 mph setting. Page 87 of owner's handbook states" in certain conditions, such as a steep downhill gradient", the vehicle speed may exceed the set speed limit. This is because engine braking is unable to maintain or reduce the vehicle speed. Asl allows select between cruise control and asl. Once set, further accelerator petal pressure will not increase speed beyond set speed. System failed, and a surge in speed to 90 mph from set 69 mph happen.incident immediately reported to Jaguar of huntington,1249 E. jericho turnpike, huntington, NY, 11743(631-427-2708) tech could not duplicate customer complaint at that time. Accelerator pressure had been applied due to many hours of operating from trip from Florida to huntington, NY(selling dealer's location). Asl may have become disable and erronoursly responded to petal position. Hard braking applied to avoid collision with merging vehicles on I 95 in Maryland.

I was on highway with my family travelling 60 mph when the car suddenly accelerated.. I took my foot off the gas and the speed failed to decrease. I applied the brakes which did work but the engine still continued to race.. the brakes overtook the acceleration and slowed the car but each time I took my foot off the brakes the car resumed accelerating at a high speed( without my foot on the gas.) I slowed the car by applying with force the brakes which was causing a burning smell probably from the brake pads. I drove the car to the closest shoulder of the highway ( about 1/2 mile) that I encountered at which point I placed the car in neutral while it was still moving slightly while my foot pushing hard against the brake.. while the car was in neutral the engine still continued to race although the car was stationary at that point. I turned off the engine and then waited about five minutes. After five minutes I turned on the engine at which time it was not racing. The car was taken to my Jaguar dealership and left there for three days. A report was sent by the dealer to Jaguar although my dealership was unable to determine the cause of the sudden acceleration.
