I bought a 2006 Chevy Equinox from Pomoco 10 days ago used. On the 5th day the car would not start. It took several tries. I took it to the dealer and of course it cranked right up. Yesterday, the car would not start at all after an hour of trying, so I had to have it towed to the dealership. And of course this morning it cranked right up. After doin some research I have found out that this is a common problem with this vehicle make. Chevrolet doesnt even know what exactly causes this. Whats legal rights do I have concerning the returning the vehicle back to the dealer?
