general problems of the 2012 Mazda MAZDA5

While driving my steering wheel got really harden almost impossible to turn. I nearly crash. I was lucky I was going slow. This has happened in more than 1 ocassion. I was driving in city.

The contact owned a 2012 Mazda 5. While making a turn at approximately 53 mph, the contact lost control of the steering wheel. The vehicle rolled over three times and crashed into a ditch. The air bags did not deploy. A police report was filed. The contact sustained a concussion and minor neck, back, and shoulder injuries that required medical attention. The vehicle was towed and destroyed. The manufacturer was made aware of the failure. The approximate failure mileage was 64,666.

I had 3,000 miles on my 2012 Mazda 5 when I first complained to a Mazda dealer that my car would wobble when going forward into a right turn and in reverse when making a left turn. 'something' would always correct the problem for a while when I complained during multiple oil changes. Recently at 25,000 miles a dealer finally told me my rotors were out of round so they were going to ground them down to make them straight. I requested a replacement but they said no. I would not expect nor have I ever seen rotors wear down before years of service. There is now a perception of skidding for a second when I go around a corner that I have felt twice since the rotors were supposedly made even. The car is under warranty. Has anyone else had this problem? is this a safety issue? I feel unsafe as the car has always had a balance problem. The dealer I bought the car from said he doesn't feel or see a problem and refuses to replace the rotors even though the problem has been there since I bought the car. Is there anything I need to worry about or do?.
