My aunt has a Fiesta petrol auto,63 plate, she said it has been behaving strangely pdf late. Losing power when driving, and the other day she selected drive, and it went backwards, tried again after returning to park, same thing, switched off left for a couple of minutes, started up and the throttle pedal moved by itself , increasing the revs without her touching it. When she selected drive the third time ,all was ok.
Its been to the garage, and they could find no fault, anyone come across anything like this before? Before anyone says take it back to point of purchase, it was bought from a family member, who has been a trader for over 50 years, but is now retired and well into his 80s, . The local Ford dealer aren't interested in looking at it either.
