THE MANUFACTURER SUSPECTS THAT THE HARDWARE THAT ATTACHES THE SEAT TRACKS (THE STRIPS THAT THE SEAT SLIDES ON) TO THE FLOOR MAY BECOME LOOSE OR MAY FAIL TO HOLD THE SEAT IN PLACE DURING A COLLISION. THIS CONDITION IS DUE TO THE SUBSTITUTION OF AN INCORRECT WASHER DURING MANUFACTURE. THE VEHICLES MAY NOT COMPLY WITH THE STRENGTH REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD 207, "SEATING SYSTEMS".
Consequence & remedy
Consequence: Not supplied
Remedy: THE DEALER WILL INSPECT AND INSTALL ADDITIONAL LARGER DIAMETER WASHERS ON THE BOLT ASSEMBLY.
