Dealership replaced the motor and the computer of driver's seat that was too loose and moved back and forth while driving, causing a distraction to the consumer. 6 months later, consumer experienced the same problem. The vehicles brakes squeaked, the door panel was loose, the side mirror motor failed. There was a rattling noise coming from the rear center console and there was a loud humming noise from the passenger dash in cold weather. The gear shifter broke while driving. The original windshield wiper left a black smear on the window when it rained which made it difficult to see. The front door molding warped. The consumer no longer wasn't the vehicle and has requested a refund.
