We too own a Palio D and went through the anguish of repairing the injection pump, which was pretty common in Palio diesels. That apart, i never lost faith in the product because its brilliant. I understand your situation, but to hold the entire Fiat responsible and question their build quality of each and every car produced is just not done. BMW's N54 engine was plagued by fuel pump failures, Nissan's GT-R suffered transmission failures, yet nobody questioned BMW's or Nissan's ability to produce cars of a high standard. Thats the right approach.
