THE YAW RATE SENSOR IS CAUSING THE CAR TO UNINTENDED BREAKING.

I AND MY 7 YEAR OLD DAUGHTER AND HER FRIEND WERE ENTERING MY DRIVEWAY ON AUG 14,2006, PAUSED TO OPEN MY GARAGE DOOR FROM THE CAR AND I WAS SLOWLY MOVING IN. ALL OF A SUDDEN CAR WENT OUT OF MY CONTROL IN A FLASH THAT I DID NOT EVEN HAVE TIME TO REACT. IT WENT AND HIT OUR OTHER PARKED CAR IN THE GARAGE WITH SUCH A HUGE FORCE THAT THE SECOND CAR LITERALLY WENT AND TORE THE BEDROOM WALL. OUR SECOND CAR IS BADLY DAMAGED ON THE FRONT, BACK AND ONE SIDE (SCRAPING A POLE IN GARAGE) AND WALL NEEDS FIXING TOO. I TRULY SUSPECT THERE IS SOME MECHANICAL PROBLEM FOR THE SUDDEN/UNINTENDED ACCELERATION THAT LED TO THIS UNEXPECTED BEHAVIOR. SO FAR WE FOUND THE IGNITION GOT JAMMED (COULD NOT START AND HAD TO BE TOWED IN), OTHER THAN THE BUMPER/FRONT DAMAGES. CAR IS STILL IN THE BODY SHOP FOR REPAIRS, ONCE FINISHED IT WILL BE TAKEN TO THE DEALER FOR FURTHER ANALYSIS AND CHECK UP. *NM

CRUISE CONTROL STALK IS TOO LONG, MAKING ACCIDENTAL ACTIVATION OF CRUISE CONTROL LIKELY WHEN ACTIVATING THE RIGHT TURN SIGNAL. HITTING THE CC STALK WHEN MAKING A RIGHR TURN ACTIVATES THE "ACCEL" PORTION OF THE CRUISE CONTROL. THERE IS NO VISUAL INDICATION (DASH LAMP, ETC.) THAT THE CRUISE CONTROL HAS BEEN ACTIVATED.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
