2014 Subaru Forester

THIS INCIDENT IS NEARLY IDENTICAL TO AN EARLIER COMPLAINT: NHTSA ID NUMBER 10574697. I WAS TRAVELLING ON A STRAIGHT PORTION OF INTERSTATE AT REDUCED HIGHWAY SPEED DUE TO COLD WEATHER AND LIGHT SNOW WHEN I BEGAN TO EXPERIENCE A WIGGLING SENSATION IN THE REAR END OF THE VEHICLE. LIKE DESCRIBED IN THE EARLIER COMPLAINT IT FELT LIKE THE REAR END WANTED TO STEP OUT, FIRST ONE WAY AND THEN THE OTHER, REPEATING RAPIDLY. I COULD SEE FROM THE REACTIONS OF DRIVERS BEHIND ME THEY WERE GIVING ME A WIDE BERTH AND COULD TELL SOMETHING WAS VISIBLY HAPPENING WITH MY VEHICLE. THE FRONT END DID NOT APPEAR TO BE AFFECTED NOR WAS THE ABILITY TO STEER THE VEHICLE. ONCE I DECELERATED TO 45-50 THE WIGGLING ABATED. IT WAS SNOWING AT THE TIME BUT THERE WAS NO MORE THAN A TRACE ON THE ROADWAY. NO OTHER VEHICLES AROUND ME SEEMED TO BE HAVING ANY DIFFICULTIES WITH TRACTION AND MOST WERE TRAVELING AT FULL HIGHWAY SPEED (70). MY ABILITY TO STEER AND BRAKE, EVEN MODERATELY, WASN'T AFFECTED AS I COULD SLOW IMMEDIATELY AND CHANGE LANES AND THE FRONT END DID NOT SKID. I TRAVELLED AT NO FASTER THAN 50 MPH FOR ABOUT ANOTHER 5 MILES AT WHICH TIME I SLOWLY ACCELERATED AND WAITED FOR THE WIGGING TO RESUME BUT IT DID NOT. I WAS ABLE TO COMPLETE MY JOURNEY (ANOTHER 40 MILES) WITHOUT FURTHER INCIDENT. I'M VERY EXPERIENCED IN WINTER DRIVING BUT THIS IS MY FIRST TIME WITH AN AWD VEHICLE. I HAVE NEVER EXPERIENCED ANYTHING LIKE THIS IN MY LIFE AND IT WAS QUITE UNNERVING. I DON'T KNOW IF THE VEHICLE WAS INDEED STEPPING OUT DUE TO SLIPPERY ROAD CONDITIONS (ALTHOUGH NOBODY ELSE SEEMED TO BE HAVING ANY DIFFICULTY) AND THE AWD SYSTEM WAS CORRECTING (OR OVERCORRECTING?) AS DESIGNED AND THAT WAS THE WIGGLING I FELT. IT'S NOT OCCURRED AGAIN . . . BUT I'VE BEEN CAREFUL TO AVOID SIMILAR WEATHER CONDITIONS (DEFEATS THE PURPOSE OF OWNING A SUBARU) AND HAVE NOT EXPERIENCED IT IN DRY WEATHER. *JS
