When both back windows are down and driving at approximately55-65 mph vehicle will shake and steering wheel will vibrate . There is no solution, but vibration will stop if all the windows are up or if all are down. Also, at only 48,000 miles rust is developing in cooling system possibly due to radiator . Dealer claims rust is normal,and that the cause is due to engine block. But, the engine block is made out of aluminum which does not rust.
