Door lock disintegrated the day after I got it home. Taken to the local Fiat dealer (driving whilst holding the door shut is not an experience I would like to repeat).
Alternator packed up.
EGR valve broke in January 2013. New one became clogged and 'sooted up' within 4-5 months, and had to be taken to pieces and cleaned to stop strange kangarooing and twitchy driving style.
Alloy wheels corroded (water gets behind the lacquer on the polished rims). A well known fault on the early models.
Engine computer says to check spark plugs - then changed its mind and said 'check engine'.
Battery fuse blown - engine management light is now on continually.
Door sills have now 'moved' or perished as there seems to be a blowing noise at anything over 40mph.
Engine has a rather agricultural sound when idle/cold, and can take a while to quieten down.
Even though things have gone wrong with this car, it hasn't been a money pit or suffered many of the hideous problems that I read about before buying. I still enjoy driving it, and like getting into it every day.
It's punchy and quick, and has lots of pull in all gears. Economical too; my daily commute is a mixture of A & B roads with a small blip of dual carriageway, and it returns over 40 MPG all the time. A more recent long haul trip, loaded to hilt, including the dog, and it still returned 54 MPG.
Was great in the snow too, leave it in 3rd gear, take your time and it would go anywhere.
It's easy to park and the 'city button' is handy in some of the tight UK multi story car parks.
The styling is fantastic and I love the look of it. Mine is chemical grey, which has a deep shine when polished and was the colour I wanted it in.
Seats are very comfortable, supportive and everyone comments on the quirky 'bubbles' that make up the pattern. Bolsters have so far suffered no signs of wear and the seats look like new.
Interior is a nice place to be and there are no rattles or squeaks (apart from the boot lid), but nothing from the dash.
Chunky leather steering wheel, gear knob and handbrake make for nice touches.
Blue & Me system - whilst it can be a touch temperamental and doesn't play anything other than MP3, it's a good piece of technology, and the pairing of the phone and voice controls work well.
Overall the car drives very well and I've been very happy with it.
I like the look and the styling, and the fact that you don't see lots of Sporting's on the road. It's something a little bit different.
