Ford service in question

I can't help but wonder at the high number of complaints you receive regarding Fords, and the equally high number of issues where the Ford dealer will not readily accept the problem and promptly fix it without giving the customer a hard time. Is this common, as I thought a 3-year warranty meant just that, and covered virtually everything apart from consumables such as brake pads etc? Are there people who have had problems, but have had them fixed promptly and politely without a fuss, under warranty? It seems to go against Ford's branding and apparent ideology in their adverts on customer care, corporate ethics and reliability of product and warranty.
