My father in law is on his seventh brand new F150. He tends to keep them for about 3 years each or about 80,000 miles. Currently he has a 2004 which is the first year of the current design. At about 37,000 miles, the air conditioner failed. I checked the fuses and relays which were all fine. Turns out, the compressor (or whatever is attached to the belt system) had literally fallen off. The bolt had sheared off and it was there at the bottom of the engine bay.
He usually gets the 70,000 or 80,000 mile extended warranty but was literally out of town when the 36,000 mile warranty expired. Not two weeks later this problem happens. He talked to his sales guy, then talked to the service dept. They worked with him and fixed it under warranty as long as he would buy the extended warranty. Seems like a decent fix to a bad problem in my book.
He said the only other problem was about 1986 when he had the big 300 inline six or whenever the 300 first got fuel injection. He said that if you drove it slowly, it was fine and if you floored it, it was fine. But if you accelerated normally, when you backed off the gas to shift, it would surge and buck and do all kinds of bad things. He had to take it to the dealership about three time. They never drove it except to pull it into the bay, so they were driving it slowly so they didn't experience the problem. The computer (or machine or whatever they had back then) checked out fine. After being told there was no problem, for three times in a row, he MADE the service guy go for a ride with him where the problem presented itself. It was fixed under warranty and he never bought from that dealer again.
I've never owned a new Ford though I've owned a couple used ones. After having experienced Honda and BMW serive (both absolutely TOP notch every single time), I think I would find it endlessly frustrating to have a dealership tell me there was no problem when obviously there was. I know this will come down to individual dealerships and even individual sales staff and service staff but in my opinion, assuming buyers are reporting their experiences to Ford headquarters, individual experiences are probably indicative of what Ford wants the buyers experience to be.
Honestly I have nothing for or against Ford, but I think they - along with GM - could aim a little higher.
