NHTSA Complaint #10876453 — 2012 MAZDA MAZDA3

THERE IS A PROBLEM WITH THE DOOR SENSOR ON THE REAR PASSENGER DOOR. AT RANDOM INTERVALS THE INTERIOR LIGHTS WILL TURN ON AND THE DASH INDICATES THAT THE REAR PASSENGER DOOR IS OPEN AFTER THE DOORS AUTOMATICALLY LOCK DUE TO SPEED. THIS WILL CONTINUE UNTIL I UNLOCK THE DOORS. UNFORTUNATELY THEY RELOCK AUTOMATICALLY IF I STOP FOR A TRAFFIC LIGHT AND THEN ACCELERATE. THE INTERIOR LIGHTS COME BACK ON AND THE DASH INDICATES THE DOOR IS OPEN AGAIN AS SOON AS MY SPEED IS SUFFICIENT TO MAKE THE DOORS AUTOMATICALLY LOCK AGAIN. THIS IS A NUISANCE DURING THE DAY BUT A MAJOR DISTRACTION AT NIGHT. HAVING THE INTERIOR LIGHTS SUDDENLY TURN ON WHILE DRIVING AT 10 PM IN THE RAIN IS HORRIBLY DISTRACTING AND A LITTLE SCARY. THIS WILL SOMETIMES OCCUR FOR 2-3 DAYS IN A ROW AND THEN NOT HAPPEN AGAIN FOR 2-3 WEEKS. MY CAR HAS ONLY 38000 MILES ON IT BUT THE DEALER SAYS THIS ISN'T COVERED UNDER ANY WARRANTY.
