Brake Disc Rotor problems of the 2003 Mazda Tribute

At 38,800 miles, I had to replace my brakes pad and rotors, now at 49,785 I will need to replaced my rotors again. I believe these rotors are defected. Please investigate this issue.

2003 Mazda Tribute 2wd v6 - brakes worn and and roters worn and rippled beyond repair at 30,000 miles. Per dealer rep, they have seen this problem on many Mazda Tributes. Dealer rep stated if not replaced, high potential for brakes heating and causing fire. Vehicle is driven about 60% city driving and about 40% highway driving.

During a routine maintenance visit, I requested that the front disc brakes be inspected and serviced if deemed necessary on this vehicle. The mileage at the time was 38,400 and the vehicle had been serviced on multiple occasions by the Mazda dealership from which it was purchased. The service advisor called me to inform me that the brake rotors were worn and would have to be replaced to ensure the vehicle remained safe to operate. They refused to replace the brake pads alone. When I retrieved the vehicle (without the brakes being serviced), I inspected the rotors to find a very unusual wear pattern on the rotors. The pads (which had several thousand miles left to go) had "cut" a perfectly smooth/flat groove into the rotor surfaces across the entire width of the pad surface - leaving a raised edge on the inner and outer edges of both sides of the rotors on the driver and passenger sides. It appears that the brake pad material is harder than the rotor material and the wear on the rotor was equivalent to the wear of the pads.

Catastrophic front disc brake failure on 2003 Mazda Tribute after only 56,651 miles, requiring complete replacement of both front disc pads and both front rotors. Dealer indicated that they were seeing excessive wear, and frequent replacement on front disc brakes, which indicated that they were under designed by Mazda or that Mazda was using inferior quality brake pads.
