You shouldn't have to purchase another vehicle. At this point, I think the lemon law states they need to replace the vehicle with another vehicle or refund your money. Then you could get another car somewhere else. I am really close to filing a lemon law claim against ford. I am being very patient waiting to hear back from Mother Ford and my dealer about what to do next. I told them I love the car and everything about it but the noise. I am willing to take a replacement vehicle just like mine but I am not going to trade this in for another. I want them to replace it with same cost and mileage if necessary. I don't even have 6,000 miles on it.
