NHTSA Complaint #11171104 — 2011 FORD F-150

I STARTED MY TRUCK AND TURNED IN THE REAR DEFROST. APPROXIMATELY 2-3 MINUTES AFTER STARTING THE VEHICLE AND ACTIVATING THE REAR DEFROST I WAS ON THE ROADWAY WHEN I HEARD A LOUD SOUND AND NOTICED MY REAR PASSENGER SIDE WINDOW WAS SHATTERED BUT OTHERWISE IN TACT. THE WINDOW FRACTURES COVERED THE ENTIRE WINDOW. I INSPECTED THE DAMAGE AND SMELLED WHAT I BELIEVE WAS WIRES OVERHEATED/BURNING. THE TEMPERATURE OUTSIDE WAS 9 DEGREES AT THE TIME. I BELIEVE THE REAR DEFROST LIKELY MALFUNCTIONED AND OVERHEATED THE WINDOW TOO QUICKLY CAUSING IT TO SHATTER. AT THE TIME THE DAMAGE OCCURRED I WAS STOPPED AT A RED LIGHT.
