Problems with gearbox on 2013 Ford Focus

I have just bought a 2013 Ford Focus sedan from a Ford dealer for $12,000. He gave me three-months warranty, but he didn't tell me about the problem with the dual-clutch gearbox. I want to return the car, and he is willing to pay me $9000. How can I get the full refund, because this car is not fit for the purpose?

If only it was that easy. I assume that it’s not giving you any trouble now, but if it is you could get it repaired under the warranty. If it’s not I don’t see you have grounds for a full refund, even though that model has a poor reputation for its transmission troubles. If you had done your homework before buying it you would have found lots of reports on the troublesome transmission.
