DRIVERS SEAT FAILED TO LOCK INTO POSITION, THIS WAS SECOND OCCURRENCE. WHEN BRAKES WERE APPLIED, DRIVER WAS THRUST AGAINST STEERING WHEEL HITTING CHEST AND FACE AND INJURING WRIST, KNEES HIT THE DASH, SEAT RAN ONTO LEFT FOOT. SEATBELTS DO NOT HELP AS THEY ARE ATTACHED TO THE SEAT. WHEN DRIVING, SEAT SLIDES FORWARD AND BACKWARD FREELY. WHEN THE BRAKES ARE APPLIED THE SEAT SLIDES FORWARD, CAUSING THE FOOT TO HIT THE BRAKES HARDER, THEREBY CAUSING AN ABRUPT STOP. LUCKILY MY CHILDREN WHO WERE PASSENGERS AT THE TIME HAD THEIR SEATBELTS ON OR THEY WOULD HAVE HIT THE DASH. MOST VEHICLES NEVER HAVE THIS OCCUR IN THEIR LIFETIME, BUT THIS HAS HAPPENED TWICE WITHIN A YEAR AND A HALF. FIRST TIME WAS AUGUST OF 2000. COST TO REPLACE IS OVER $500. I FEEL THIS IS A SEVERE SAFETY CONCERN DUE TO THE FACT THAT YOU CANNOT CONTROL THE VEHICLE WHEN OPERATING, ESPECIALLY WHEN STOPPING. THE SEATBELTS DON'T HELP AS THEY ARE ATTACHED TO THE SEAT. MAJOR CONCERN FOR ME IS IF I AM IN AN ACCIDENT THESE BRACKETS WILL NOT HOLD!!! I AM A 120 POUND WOMAN, I DO NOT ADJUST THE SEAT OFTEN, I KEEP IT POSITIONED ALL THE WAY TO THE BACK. MY NORMAL WEAR AND TEAR COULD NOT HAVE CAUSED THESE RAILINGS TO BREAK. I HAVE CHILDREN WHO WILL BE COMING OF AGE TO DRIVE. WHAT WOULD HAPPEN TO A LESS EXPERIENCE DRIVER? WHAT IF PASSENGERS DIDN'T HAVE SEATBELTS ON? WHAT IF I WAS HAULING A TRAILER? WHAT OF THE FORCE OF THE ADDED WEIGHT OF THE TRAILER WHEN STOPPING? WHAT OF THE CONTENTS ON THAT TRAILER? WHAT IF
