I recently purchased a vehicle that seemed to be alright at the start. A couple days later I started hearing odd noises. I tried calling the dealer back and asked if I could bring the car in to be looked at and serviced. They told me they could not help me because they did not have any certified mechanics for my make of vehicle. On top of that they sold me an extended warranty.So I decided to take it to an actual dealer where they sell my make of vehicle and they call me later that day to give me the breakdown of what is all wrong with the car. Then after they listed the issues with the car they then tell me that the warranty will not cover the damage to the car. Is it legal for them to sell me a warranty knowing that it wont work cause the aftermarket parts? What can be done on this?
