Bess–Here is a reality check that might help you to some extent.
The tires on a new car are warrantied by the tire manufacturer, NOT by the car’s manufacturer. This is the case for all vehicles, and if you check inside your glove compartment, you should find both the Tire Warranty booklet from Continental and the Ford Owner’s Manual which clearly states that the tires are warrantied by the tire manufacturer. I don’t blame you for being livid, but if anyone told you that a vehicle manufacturer warranties the tires on a vehicle, that person is flat-out wrong.
As to the BBB, I suggest that you save your effort, and possibly your money. The BBB is essentially a private club that retailers can join–for a fee. If you file a complaint with the BBB regarding a business that is a member of the BBB, the business will receive a polite letter from the BBB, asking (NOT demanding) that the member business satisfy your complaint. If they do not satisfy your complaint, the penalty is…essentially nothing. If there are repeated complaints about a member business, the BBB’s ultimate penalty is to refuse that business’s membership dues for the following year. Because the BBB is itself a profit-making organization (local BBB franchises are sold by the parent organization, just as franchises for businesses such as fast food joints are sold), they hesitate to refuse the dues that are the major part of their profit structure. The other part of their profit structure is the fee that many local BBBs charge for you to file a complaint with them.
On the other hand, if the business in question is not a member of the BBB, then nothing is done, other than to record your complaint and maintain a record of those complaints. And, as I previously pointed out, there may be a fee for having them place your complaint in a file cabinet and/or a computer data base. Clearly, they can not–and will not–do anything in terms of pressuring a business that is not a member of the BBB. Now you know why so many people refer to the BBB as the Better FOR Business Bureau.
For some reason, many people think that the BBB is a governmental entity with regulatory and punitive authority, but nothing could be further from the truth. The Consumer Affairs Office (run at either the state or county level, depending on your location) does have punitive authority, but I have to say that your situation may be beyond their scope. Unfortunately, the tires that new vehicles are supplied with are rarely the best quality, and many people wind up replacing those tires within a fairly short period of time. Admittedly, your situation may be more extreme than most, but this would not be the first time that someone was very unhappy with the tires that came on his/her new car.
All of that being said, the wear pattern that you have described is likely to be the fault of either bad alignment or poor vehicle design. I would suggest that you continue to pursue the issue with Ford Customer Service, and possibly even contact Alan Mulally, the CEO. But, your complaint should be framed in such a way that you are complaining about the vehicle, not about the tires. Ford will swifty dismiss your complaint if you try to hold them responsible for something relating to a warranty on those Continental Tires, simply because Ford warranties the vehicle, not the tires.
