My Focus SE grinds like crazy in the first 3 gears now. It's so bad we could never even sell the car privately. What's even worse now is that it pops in and out of gear at random times.
Of course my dealer "The Ford Store" in San Leandro California has been no help at all. They told me "thousands of owners" are complaining and that if I'm that unhappy I should just Lemon Law the Car. Even the dealers have given up on the mess of a Car!
