Brought focus in at 31000 miles back on Jan 10,2013, with a thumping noise in the rear drivers side wheel. Was told in writing that I needed new tires, at the time I couldn't afford them so I drove till I had 55000 miles on the car then bought new ones last Sat. I though just tires so I drove on them. After getting new tires the thumping was still there, same noise. Called Londonderry Ford and they said it was covered on the drive train warranty and bring it in. After they checked it out they said it is a bad rear wheel bearing and will cost $449.00 to fix and not covered. So I though it should be covered the first time, same noise, now it has 55000 miles, out of warranty. They should of found the bearing the first time but blew me off, saying tires.These guys are ripping people off and service department not willing to work with you. Called another Ford dealer and they are repairing my car tomorrow under the drive train warranty, they are very help full, I will never go back to Londonderry Ford again and will also get the word out there. Very unhappy with the service they give.
