Prior to this date, which lead up to the last incident, upon getting the first few oil changes, at a dealership where I purchased the car, the engine began to sound like a truck (oil used was not synthetic and I were scheduled to come back in 5-months). When I inquired about it, I was told, "that was the way it was supposed to sound". after that comment, I changed to another dealership for service. The knocking continued, to this day, still. Over the years, the system lights would come on periodically (passenger air bag, check engine light and tire sensor) and the cooling fans would run after you turned the car off. Most times, they would reset themselves. Moving along, recently on 07/15/14, I was returning home for the evening and the car shut down on me. The steering control was hard but I kept it from crashing the wall on Lincoln dr. As I flagged the traffic to proceed, I was able to start the car only to advance to the end of the drive. Before I reached home, the car shut down 5-times. Finally reaching home it sat until I were able to get it to another dealer, closer to home. How about, the engine is shot, the radiator had a leek, I knew nothing about and the dealer says, "it will not start, now". I drove it to the dealer. Oil light was on and smelling as if I burned something, while it knocked. Check engine light and passenger air bag light were on when it cut-off, as I pulled into their driveway. I restarted the car found a parking space. Once the ignition shutdown, the cooling fans came on. Dilemma, I leased the car new in 2007. I bought it, with present car payments until 2016, in 2010. The dealer requests the engine and radiator to be replaced. There is no warranty, especially after 100,000 miles and I have scrap on my hands. Where does one go from here as Mazda used to be reputable? the engine shouldn't have any problems before 200,000 miles.
