The contact stated that one hour after he purchased the vehicle the check engine light came on. He had it checked by a mechanic, and it was determined that catalytic converter failed. It was fixed because it was under warranty. The egr valve needed to be fixed. The Mazda dealership gave consumer an estimate for over $200, and they will not fix it because it is not covered under the warranty. The Mazda dealership where he purchased the vehicle said they would fix it under the warranty but he has to take the time to bring the vehicle back there again.

Strong heavy fumes entered vehicle, causing driver and passenger to become nauseated. Consumer has gotten mixed diagnosis of what the cause could be. Dealer's technican believed some substance leaking from engine and dashboard compartment caused fumes to enter vehicle while air conditioning was on. Consumer lived in a hot climate area that required air conditioning to run a lot. Mazda never heard of complaint, and believed fumes might come from interior. Mazda didn't have a remedy.
