I bought my Focus in
2012 with 27k miles on it. I sold it 8 months later with 47k. The dealership even let me take it home for 3 days to make sure i really wanted it. Fair enough. But 1 wk after the purchase it started bucking especially when going up a hill and in the 1st and second gear.intermittantly. I traded a Mazda 3 manual and it felt like somebody was driving it that didn't know how to shift, and that wasn't me, because this is an automatic transmission. I took it in 3 times and was told that's how it drives. Then the engine light came on. took it back in and they replaced the clutch and it fixed the problem. also, the vaporizer was bad. Nothing but a headache.
