A brake pedal pulsation may be noted on brake apply. This is commonly caused by warping of the front brake rotors. Our technicians remind us that re-machining (turning) the rotors can correct this issue but the repair may last only a short time as the thinner rotors would be even more prone to warping. Replacement of faulty rotors with high quality parts is often the best option in these situations.

Reported by sargentr and 2 others for the Mitsubishi Diamante

this morning on my way to work my cuise stopped holding speed. I turned it off and tried angain and it would not work. I am getting power to the switch and the dash show cruise on, but it will not hold the speed. I also thought the trans might have been slipping, but as soon as I released the cuise and pressed on the gas it was fine.
