Hi Matt, welcome.
Great question. Actually prompts the suggestion that we need a 'common faults' table not assocated with any particular model forum. This would allow people to quickly scan for their vehicle, find common problems and then go to the vehicle forum. A point to remember is that may models share commons parts/issues/designs so for example Barchetta 1.8ie, Punto HGT, Coupe 1.8, etc. have, or potentially have similar issues and a person reading in detail the Punto forum will miss stuff posted in the Barchetta and Coupe forums.
I can go back to 1974 with a Fiat 600 right through to today with a Croma. Vehicles owned and serviced by me in that time being 600, 127, Strada, Uno, Tipo, Tempra, Coupe, Punto, Barchetta, Stilo, Croma ... 14+ cars in all.
I'm probably not the only one here who has this sort of cover. Some people here also work in dealerships so have seen plenty too.
