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? updated 09/05/13*lj
