When braking down hill the rotors warp making it almost impossible to stop in an emergency. Dealership paid for the second repair, car was about a year old, saying it was a defect in the design, lightweight rotors, calipers and brake pads. Luckily I live in an area that is flat. Every time I go out of town I have to deal with this fear and a repair job. An independent mechanic said I needed to upgrade to heavy duty rotors and calipers. Said this took care of the problem in a Cadillac with the same problems. It's a 2k fix but dealership refuses to fix it because I am a woman am heavy on the brakes downhill and that his wife can't drive either. Also said they won't fix the defect due to me taking the car to an independent mechanic. I had to as they kept turning the rotors even though they can only be turned 2 x. This defect will eventually cause an accident but until then I just hope for the best.
