Door problems of the 2007 Ford Focus

3 of 4 doors have now broken on my 2007 Focus, due to the same problem as what was recalled on the 05 model -- the doors will not latch and/or lock. The door mechanism is the same for 2000-07, so I'm not sure why 07 was not recalled as well. I paid the dealer over $1000 to fix the front driver and back passenger doors in 5/12, and now in 7/12, the back driver door is doing the same thing -- when you go to shut it, it just pops back open, as the latch does not catch. I had to drive home from my baby shower last night with the rear doors tethered to eachother to keep the door from flapping open while I drove down the road. I have spoken with the service manager at the dealership, as well as Ford corporate, and have basically been told it's not their problem and I am on my own to pay for the repair, because my car is "too old" (just 5 years from mfg date) and has "too high mileage" (not that the doors have anything to do with mileage) for Ford to take any responsibility for what is clearly an issue of cheap, faulty parts and poor workmanship. This problem is all over the internet, and is clearly not isolated to my vehicle. Ford should be ashamed of the fact that they have ignored this problem, which could cause serious injury to it's customers (just imagine if the latch had stopped working while I was doing 70 mph down the highway!), and neither I nor anyone in my family will ever buy another Ford!.
