“I own a Jaguar 1999 XK8- it has repeatedly gone into the limp home mode while on the freeway twice causing cars around me to crash while avoiding me.

I have just had a different shop work on it and have gone back 3 times with out it being fixed. I am now afraid to drive in any lane other than the right lane. In trying to find a solution I found that it has been the cause of some accidents and is not uncommon. …”
NHTSA complaint #10267099, filed 2009-04, 51,000 miles“Sudden loss of power. This is due to the stabliity control chip located in the throttle body going bad. When the wheels break loose, a sensor sends a signal to the chip in the throttle body to slow the engine so it does not over-rev. This chip according to the dealer is malfunctioning and 'firing' on its own resulting in a sudden loss of speed. This first occurred 18 months ago and I had to replace the throttle body ($1800). It just started to happen again and the new throttle body only had 13k miles on it. I just had to replace again and they only charged me another $730. …”
