I bought a 2015 used Ford Fiesta from a Honda dealer, but it's developed a noisy engine on start up. I returned it under warranty three month later, but they failed to fix it. They did not disclose the car was still covered under manufacturer warranty. As they did not repair it and I was not happy with the car, I was offered a value that they said took into consideration fair usage (£690 for three months) and I traded the car for another paying an additional £1000. The new car developed a fault and on return to the garage, the original Fiesta was again on sale at the original price I purchased it. I'm not aware if it's been repaired or if they are selling it with the same fault. Can I claim for lost expenditure, which would not have been incurred had they repaired it or took it to the manufacturer for repair? I have also since found out my new car has been in an accident with two nearside doors being repaired. The dealer was informed of this by the previous owner (I have spoken to the previous owner), but it wasn't disclosed to me. The dealer told me it was illegal to phone the previous owner as well.
