Why the hyperbole? You're obviously angry and out of patience. But, "poorly designed brakes?" Really? Brembo. The rotors are good. The pads are the common denominator here; and really, it's only in front; I think that I've read two maybe three cases on here of shuddering coming through your butt, i.e. the
seat, indicating rear pad deposits. Just swap out the damn pads and move on! It's a fallen world. Kia says up front in the US warranty: 12K miles on brakes. After that the replacement is on you, even if you lease and turn the car back in. So, either do something to enjoy the ride, or keep complaining. The choice is all up to you and you alone.
