| At about 5000 miles i noticed grooves developing in the rear brake discs. at 10,000 miles i have only 35% left in the rear brakes as the grooves have deepened and now damage the pads every time they are engaged. at this rate the brakes will fail at before 16,000 miles of use. | |||

| The rear brakes started making some noise at 15,000 miles. looked at them and didn't see any unusual wear. checked again at 18,000 miles and the rear rotors on both the drivers side and passenger side are scored terribly, was going to get them resurfaced but the metal is beyond repair. i checked online for a possible fix when i came across a forum site specifically for my car that has listed multiple incidents in this same nature with the same car. | |||
