NHTSA Complaint #10317317 — 2007 SUBARU OUTBACK

2007 SUBARU OUTBACK 2.5I WITH SNOW TIRES (SNOW FLAKE SYMBOL). I FIRST NOTICED THE OCCURRENCE LAST YEAR WHEN DRIVING SLIGHTLY SNOWY ROADS IN COLORADO,. THE BACK END OF MY CAR WOULD WOBBLE SIDE TO SIDE AT A HIGH RATE -- PROBABLY 5 INCHES TO EACH SIDE. IT FELT AS IF THE CAR WAS SENDING POWER TO EACH WHEEL INDEPENDENTLY. THE FASTER I WOULD GO, THE MORE VIOLENTLY IT WOULD WOBBLE SIDE TO SIDE. I WAS SUDDENLY HAVING TO DRIVE 20MPH ON INTERSTATE 70, I WAS BEING PASSED BY LARGE SEMI- TRUCKS AND LITTLE MIATAS. SINCE THEN, I HAVE FELT THE WOBBLE ON GROOVED CONCRETE SURFACES, BUT MOSTLY ROADS THAT HAVE A LITTLE SNOW ON THEM, BUT I CAN STILL SEE THE ROAD SURFACE. ONE TIME, THE CAR WOBBLED SO VIOLENTLY THAT IT SWUNG INTO ANOTHER LANE. I'VE CONTACTED SUBARU AMERICA, BUT THEY HAVE BEEN VERY LITTLE HELP AND DO NOT SEEM TO TAKE IT SERIOUSLY. I KNOW SEVERAL OTHER 2005-08 SUBARU OUTBACK DRIVERS THAT THIS HAS HAPPENED TO. OUR BEST THEORY IS THAT THE SUSPENSION IS TOO SOFT AND WHEN IT GETS WEIGHTED DOWN (WITH TWO OR MORE PEOPLE IN THE CAR) IT CHANGES THE GEOMETRY OF THE SUSPENSION AND THE ALIGNMENT WITH SOME HOW PLAYS WITH THE REAR DIFFERENTIAL. *TR
