“This car vibrates when traveling at speeds of 40mph and 65mph. Significant vibration can be felt in the center console and armrest. My car has a especially severe vibration around 40 MPH when driving up a hill and the transmission is set to eco mode. Vibration can be felt in the steering wheel and the driver and passenger front seat. Tires were road force rebalanced by the dealer, but the problem persists. Since it is at only certain speeds, the cause of the problem has not been identified by the dealer.”
