I HAVE PURCHASED A NEW 2007 NISSAN XTERRA S 4X4 SUV SO THAT I CAN GO OFF-ROADING FOR SPORTS ACTIVITIES SUCH AS SKIING (SNOW), HUNTING (MOUNTAINS, DIRT ROADS). HOWEVER, I HAVE WENT TO TEST THE 4 WHEEL DRIVE SYSTEM OF MY VEHICLE SEVERAL TIMES TO OHV PARKS, AND THE LAST TIME I VISITED A PARK, I WAS DRIVING THROUGH PLAIN MUD ON A PLAIN DIRT GROUND AND WITHOUT ANY IMPACT NOR ANY BAD DRIVING THE CURTAIN AIRBAGS FROM BOTH SIDES HAVE DEPLOYED GIVING ME A TRAUMA FOR AIRBAGS. I HAVE TAKEN THE CAR FOR REPAIR TO CERRITOS NISSAN DEALER, BUT THEY TOLD ME THAT IT WILL NOT BE COVERED UNDER WARRANTY BECAUSE THE CAR HAD A ROCK DENT FROM PREVIOUS OFF-ROADING WHICH HAD NOTHING TO DO WITH THE DAY OF THE AIRBAG DEPLOYMENT. AS FOR EVIDENCE, I HAVE UPLOADED ON YOUTUBE THE VIDEO OF MY AIRBAGS DEPLOYING SO THAT PEOPLE CAN SEE THAT IT DEPLOYED FOR NO REASON. IT IS BRAND NEW VEHICLE, WITH LESS THAN 7500 MILES ON IT, THE DEALER WILL NOT RESPOND, AND SO I HAD TO TALK WITH NISSAN AMERICA CORPORATE OFFICE IN WHICH THEY WILL MAKE ANOTHER ANALYSIS OF THIS VEHICLE IN WHICH I DO BELIEVE THAT IT IS A DEFECT. FOR THIS REPAIR, THEY WILL HAVE TO REPLACE THE ENTIRE ROOF CEILING IN WHICH I DO NOT BELIEVE THAT IT WILL BE THE SAME AS BEFORE, AND SO I HAVE REQUESTED THEM TO GET ME A NEW VEHICLE BECAUSE I LOST CONFIDENCE OF MY DEFECTIVE ONE. FROM NOW ON, I WILL HAVE THE TRAUMA OF AIRBAGS DEPLOYING AT ANY TIME, AND I AM DOING THIS COMPLAINT BECAUSE I DO THINK THAT IT IS DANGEROUS TO LET THEM HAVE SUCH SYSTEM B
