EXITED INTERSTATE HIGHWAY, TRAVELED UP RAMP, WAS UNABLE TO LIFT LEFT FOOT TO BRAKE (POSSIBLY CAUGHT UNDER PARKING BRAKE PEDAL, WHICH IS CLOSE TO THE BRAKE), TRAVELED THROUGH INTERSECTION AND HIT GUARD RAIL, CAUSING $8,800 DAMAGE TO MY 7-MO.-OLD LEASED 2007 NISSAN ALTIMA. THE WHOLE FRONT END CRUMBLED. BECAUSE I WAS NOT WEARING A SEAT BELT, I WAS THROWN INTO THE WINDSHIELD, HITTING AND SMASHING THE REAR VIEW MIRROR AND CRACKING THE WINDSHIELD. INJURIES SUSTAINED WERE NOT SERIOUS, BUT THERE WOULD HAVE BEEN NO INJURIES AT ALL IF THE AIR BAGS HAD DEPLOYED. NONE OF THEM DID. I AM NOW VERY CONCERNED ABOUT THE SAFETY OF MYSELF AND ANY PASSENGERS I MIGHT HAVE IN MY CAR. THE DEALERS SERVICE CENTER SAID THAT THE IMPACT WAS TOO HIGH UP ON THE FRONT END TO TRIGGER THE SENSORS. IF MY VEHICLE HAD SLID UNDER THE REAR OF A TRUCK, I WOULD HAVE BEEN KILLED IN SPITE OF BEING SURROUNDED WITH AIR BAGS. *TR
