There are alot of other makers who will go same way as Rover before fiat do,all car manufacturers are in trouble & Fiat are along way down on the list.
Fiat are I agree paying out alot in warranty but the 'belt' is being tightened & new cheaper methods of warranty repairs are in place in known problem areas.However dont forget alot of parts are supplied to Fiat (Bosch etc) so Fiat are billing these companies for faulty units under the warranty period.
Workmanship needs improvement? well Fiat are undertaking IMI training (like ford & BMW) foe their technicians so hopefully the benefit will show through in the next few years.Workmanship at the factory? well yes cars are built on the 'cheap' (by all manufacturers) & many shortcuts are undertaken but this is because the customer wants more and more for their money (and can quite rightly go elsewhere if they choose) when they buy a car yet are happy to shell out £150,000 (average price) on a house
You get what you pay for it's as simple as that,also there are losts of posts here about 'kicking up a fuss' & trying to get dealers to do work for nothing! well end of the day its the customer that pays in one way or another.
