Sadly you would be surprised how many people fight that. We have customers that my co-workers come to me to see if we can help with good will monies. That is up to Ford. Not the store level.
I had a customer buy a truck at Auction with a Blown Motor expecting it to be replaced under warranty. In an auction situation, the only thing the manufacturer can go by is the Car Fax. This vehicle had 33000 miles on it and absolutely no documentation in Carfax other than the annual registration. According to the manufacturer, he has done no maintenance on it. Now we all know a lot of people do there own. The manufacturer does not recognize that if they choose not to for a warranty concern.
That I understand; blown engine vs getting a TSB done is apples and oranges, at least to me.
