The Ka's may not be desirable but at least they wont destroy themselves. The Punto has won such awards as '10th Worst Reliability' and it was in the '2005 Warranty Direct Reliability Survey with 48 repair claims per 100 cars.'
Here's a list from an owners forum:
Bonnet releases break. Hydraulic clutch slave cylinder may develop a leak. Clutch and transmission problems common. High number of cylinder head gasket failures being registered. Isolated report of front suspension wishbone collapse. If heater matrix fails it may leak onto the ECU immobilising the car. Electric sunroofs prone to failure. Possibility of brake master cylinder seal reversing itself leading to momentary but total loss of braking. FIAT/Alfa joint worst for breakdowns attended by German ADAC during 2001. 12th from Bottom of 100 models for reliability in Auto Express 2002 survey.
