THIS VEHICLE WHEN DRIVING AT NORMAL SPEEDS TENDS TO MAKE A HIGH ACCELERATING NOTICES, IT MAKES A PERSON FEEL AS IF SOME OTHER VEHICLE WAS PASSING ON THE LEFT SIDE AT A VERY HIGH SPEED. THE FIRST TIME I HEARD THIS NOISE, I MOVED TO THE RIGHT SIDE OF THE ROAD, THINKING THAT A SPEEDING DRIVER WAS PASSING ME. SINCE THEN, THE VEHICLE CONTINUES TO MAKE THIS ACCELERATING NOISE, SIX TO SEVEN TIMES ON A AVERAGE OF A THIRTY MILE TRIP. I FEET THAT THIS IS NOT NORMAL FOR A VEHICLE THAT IS LESS THAN A YEAR OLD. THE VEHICLE MAKES THIS NOISE WHEN IN MOTION FROM 20-50 MILES PER HOUR, AND MIGHT ALSO MAKE IT AT HIGHER SPEEDS. IT NEVER MAKES IT WHILE SITTING IN PLACE IDLING.
