Well, as suggested, my wife has been giving our Fiat 500 a good run to and from her work all last week and no warning lights have come on! Great, I thought, solved...until I drove it today, reversed out of a parking slot in a car park and 'bingo', on come the 'S' crossed out and the Triangle warning lights again! Contacted my nearest Fiat dealer by e.mail and they immediately replied saying there is a Software Fix and to bring it in.
Considering our Fiat is only 18 months old, surely this problem shouldn't be still going on, as I have read forum posts on this issue going back to 2009?
read your handbook i get the start stop unavailable message when reversing..
