A couple of times recently when I have pulled up in the car and pressed the engine 'Ford Power' Start/Stop button the engine failed to stop.

If you held the button in it would stop but as soon as you released it again the engine would fire straight back up. It took 5 or 6 presses before the engine would finally switch off.

Any one else seen this problem before, not necessarily on a Mk3 ??

Cheers
