I've had two vehicles that had me shunning Fords. One was a 2004 Lincoln LS that became mechanically totaled with only 60k miles due to lack of parts. No aftermarket to replace and FMC no longer made the part. What got me most what it was an emissions module. The car was only 13 years old. I'm pretty sure most modern Fords have the OCI reminder light. That's definitely why they did it. Even knowing and working on cars I find some of the costs annoying and I do have a tendency to follow the most restrictive maintenance schedules, so I can only imagine what the more normal car user that doesn't care about all this thinks when service comes up.My daughters friend was over one time and she had her check engine light on in her old focus (maybe 20-teens so like 2015 or something). I said I would take a look, turned out it was just the 02 sensor...sucker had 189k miles on it. Shocked she changed the oil at all but according to her every time the light came on she would "take it to the mechanic" to change the oil. She has no idea what was going in or out of the engine. But this time she said "The light wouldn't go away" lol. Different light.
My father was a mechanic and at one point he did the same. Just quit. Mechanics are interesting, they know how to do much more than work on cars, so not like he was out of work. Bought a Toyota Avalon, and it runs.
That is why I got my Si. Its salvage title, but easy rear end fix and it became my fun car/track car for under 10k USD. (But then you know, new turbo, new brakes, new wheels, new tires, and that just added up to the price of a new one).
The second was a 2014 Ford Edge. It was the vehicle that replaced the Lincoln. Braking system completely failed 3 times in 11 months. Brake pedal would fall to the floor. There was a TSB about the issue. Somehow my VIN fell out of the range. Total spent to fix was $3k. The third time when it was fixed I immediately sold it to Carvana and ended up buying the Tesla. I really hope it treats the next owner well, but I didn't trust private selling it after how it was for us. My F150 was great, but it was missing some tech I wanted and I was less than pleased with the fuel economy once my driving needs basically doubled the miles I was covering. That's when I bought the GTI. I would not consider another Ford just because of the LS and the Edge.
