I have had the steering motor replaced, the symtoms of this problem is when the steering wheel begins to twitch and then developes bad shakes when the car is not moving. The new motor cost £640 to replace.
I have also had a jammed seat belt mechanism, and a drivers door that wont shut. The sun visor is snapped as is the rear parcel shelf hinge, and the rear boot is filled with water.
My advice is dont buy fiat unless you are a car mechanic with spare time, or you feel sorry for you local garage and wish to keep them in work.
Any one fancy buying my car?, its a good runner "honest"
