“When I apply the brakes, the car shakes and jerks uncontrollably. I have had work done on the rotors as well as the brakes. I have four new tires, but problem still occurs. I am afraid that one day while driving this car the brakes will fail and cause my family and I serious injury . This is a 2003 Mitsubishi Diamante, and the incidents have occurred daily 3 months after I purchased the vehicle.”
NHTSA complaint #10114500, filed 2005-03, 30,000 miles“I have a new 2003 Mitsubishi Diamante, which Ive taken back to the dealership 3 times now with the same two issues: the front breaks make noise and my stearing wheel vibrates when I brake and the check engine service soon light keeps coming on. One of the dealers employees told me that the brakes issues was very common as sometimes the cars sit for a long time in a lot before they are sold. This does not make feel safe driving this vehicle at this moment. The dealer will fix the light and brake issue assuring me that its all fine now but the problem keeps coming back. …”
NHTSA complaint #10072858, filed 2004-05, 6,000 miles“When the brakes were applied, the vehicle vibrated uncontrollably. The driver was able to maintain control of the vehicle and drove it to a repair shop for inspection. The mechanic informed the consumer that the rotors and pads may need to be replaced. The consumer found nothing apparently wrong before the parts were discarded.”
NHTSA complaint #10083344, filed 2004-08, 11,000 miles“When brakes applied the car shakes so bad you can't control it. Brakes were worked on by Mitsubishi 3 times then replaced brakes and they are bad again.”
NHTSA complaint #10137295, filed 2005-09, 6,000 miles“Car shakes when brakes are applied. Had brakes & rotors replaced at 50,000 miles. Mechanic said rotors were too damaged to turn. After 6 months and 20,000 miles, the car is shaking again when braking. Took back to mechanic, who checked the rotors and said they need to be turned. I own a 1998 Mitsubishi Diamante, and that car does not need the rotors replaced every time I replace the brake pads. My driving is mostly highway, so I don't use these brakes much.”
