My 2003 F-250 has 360,000 miles on it. My problem is not with the truck, but the company.
It had 132,000 when we stopped at a barn in NC, on our way to Sport Horse Nationals in VA. As we backed the trailer up, we left a trail of transmission fluid. The BO recommended his little mechanic, so we took it there. We had blown a seal,( fixable, )but he recommended that get a reman replacement since we travel, so we would have the warranty....
That little dealer was super....ordered it overnite, had the truck torn down so it could go right in....we left in 1 1\2 days, with a reciept that was typed "3 yr, 36,000 mile warranty" .
At 142,000 miles, we barely made a crossing on a highway....transmission gone.
Made it home, took it to my dealer (the dealer that sold it to us, plus its replacement, people DH had gone to school with, small town). I waltzed in with my receipt, asked them to please fix my truck. They took it APART, down to the tiniest nut, and refused to fix it. REFUSED.
DH went up the FORD corporate ladder, and got nothing..They refused because my truck had aftermarket parts. First, they refused because I had no catalytic converter.(2003, most diesels did not). Then, they never would say exactly which aftermarket part disqualified it.
We borrowed a trailer, picked up the truck, drug it to a tranny shop 30 miles away, and had it fixed, by a man who stood behind his work.
The strange thing was, DH worked GETTING warranty concessions FOR Ford from Caterpillar at the time.......
