What 2,137 owners told NHTSA about the 2011 Ford F-150 Supercab Diesel

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.

EARLY ONE MORNING WHEN IT WAS AROUND 27 DEGREES OUT I STARTED MY 2011 F-150 AND LET IT RUN ABOUT 10 MINUTES TO WARM UP. I USED MY REMOTE START, WHICH TURNS ON THE WINDOW DEFROSTERS. WITHIN 3 MIN OF LEAVING FOR WORK I HEARD A SOUND SIMILAR TO A BREAKING LIGHT BULB. ONCE I GOT TO WORK I HAPPENED TO MOVE MY REAR VIEW MIRROR AND NOTICED MY DRIVER SIDE REAR WINDOW ( 3 PART, DOUBLE PANE MOTORIZED REAR WINDOW WITH DEFROST) WAS SHATTERED ON BOTH SIDES (PANES) I AM 1 OF THOUSANDS OF PEOPLE WHO APPARENTLY HAVE HAD THE SAME ISSUE. FORD DOES NOT COVER THE GLASS ON THERE VEHICLES IN ANY WAY SHAPE OR FORM, EVEN ON THERE NEWEST MODELS, AND APPARENTLY REFUSES TO FIX OR RATHER, REPLACE THESE WINDOWS WHEN DAMAGED BY THERE INAPPROPRIATELY ADJUSTED DEFROSTER. I BELIEVE THIS IS A SERIOUS SAFETY HAZARD. I FREQUENTLY TAKE MY NEPHEWS AND 2 YEAR OLD NIECE PLACES IN THIS VEHICLE. PLACED IN THE BACK SEAT FOR OBVIOUS SAFETY REASON. NOW I DONT EVEN FEEL SAFE PUTTING THEM IN THE TRUCK AT ALL. WHAT DO YOU THINK A 2 YEAR OLD IS GOING TO DO WITH TINY SHARDS OF BROKEN GLASS? ALSO TAKE A GLASS MUG, PUT IT INTO THE FREEZER FOR AN HOUR, TAKE IT OUT AND POUR HOT COFFEE INTO IT. WHAT DOES IT DO? THESE ARE COMMON SENSE THINGS.

AT APPROXIMATELY 8 IN THE MORNING ON 12/2/2018 I WAS AT A STOP GETTING READY TO MAKE A LEFT TURN, I HAD THE WINDOW DEFROSTER/HEAT ON, AS WELL AS THE REAR WINDOW DEFROSTER. OVER THE LAST YEAR THE REAR WINDOW DEFROSTER LIGHT HAS ILLUMINATED INTERMITTENTLY BUT THE DEFROSTER HAS ALWAYS WORKED. AS I STARTED TO MOVE THE VEHICLE, I HEARD A LOUD POP AND THOUGHT SOMEONE HAD THROWN SOMETHING AT MY TRUCK, BUT DIDN'T SEE ANYTHING OUT OF THE ORDINARY. WHEN I GOT TO MY DESTINATION LESS THAN 5 MINUTES AND ABOUT A MILE LATER, I GOT OUT AND LOOKED AT THE ROOF FOR ANY SIGN OF SOMETHING HITTING THE ROOF, WHEN I NOTICED A STEADY TRAIL OF SMOKE COMING FROM THE REAR WINDOW AREA, NOTICED THAT THE RUBBER HAD MELTED AND THE PASSENGER SIDE REAR WINDOW HAD SHATTERED COMPLETELY. I BELIEVE THIS IS DUE TO AN ELECTRICAL SHORT IN THE REAR WINDOW DEFROSTER CIRCUIT, I HAVE SINCE REMOVED THE FUSE FOR THE REAR WINDOW DEFROSTER WHICH DISABLES MY MIRROR HEATERS. I REQUEST THAT NHTSA INVESTIGATES THIS FURTHER AS THERE HAVE BEEN THOUSANDS OF CASES OF THIS ISSUE AND IT IS A KNOWN ISSUE AND FORD IS AWARE OF IT. IT IS A SAFETY CONCERN AS IT COULD HARM A CHILD OR SOMEONE SITTING IN THE BACKSEAT IF THE GLASS SHATTERS AND BLOWS OUT OF THE FRAME AS WELL AS SCARING SOMEONE CAUSING THEM TO REACT BY BRAKING, STEERING, ETC. AND POSSIBLY CAUSING AN ACCIDENT. AS FAR AS I KNOW, FORD HAS NOT ISSUED A RECALL AND HAS DENIED RESPONSIBILITY. THIS SHOULD BE ADDRESSED AND FIXED FREE OF CHARGE ON FORD'S BEHALF BASED ON THE FACT THAT IT IS A KNOWN MANUFACTURER DEFECT.

WHILE DRIVING AT ABOUT 35MPH ON MY ROAD I HEARD WHAT SOUNDED LIKE A GUNSHOT INSIDE THE CAB AND THEN DISCOVERED THAT MY PASSENGER SIDE WINDOW LITERALLY EXPLODED. THIS IS A KNOWN ISSUE AND SEEMS TO BE RELATED TO THE REAR WINDOW DEFROST. I CALLED MY LOCAL FORD DEALER AND THEY SAID THIS IS NOT SOMETHING THEY WILL REPLACE. I'M NOT ALONE WITH THIS ISSUE, THIS IS HAPPENING TO MANY F150 OWNERS AND NO ONE IS DOING ANYTHING ABOUT IT!

ISSUE: REAR POWER SLIDE WINDOW HEATED ON THE WAY TO TAKING MY SON TO SCHOOL THIS MORNING I HAD MY REAR GLASS DEFROST ON TO HELP REDUCE THE FOG ON THE GLASS. ABOUT 5 MINUTES INTO OUR DRIVE THE PANEL OF GLASS RIGHT BEHIND HIS HEAD SHATTERED (REAR WINDOW, PASSENGER PANEL) WITH A VERY LOUD AND SCARY BOOM. UPON PULLING OVER AND INSPECTING THE GLASS BOTH INSIDE AND OUT THERE WAS ZERO SIGNS THAT ANYTHING HAD ACTUALLY HIT HT REAR GLASS. IT IS STILL IN THE WINDOW AND SMOOTH IN APPEARANCE FROM THE OUTSIDE, JUST CRACKED INTO A MILLION SMALL PIECES. THIS IS A MAJOR PROBLEM THAT FORD AND OR THEIR GLASS MFG. NEED TO OWN UP ONE. THIS COSTS US, THE OWNERS $500+ EVERY TIME WE HAVE TO REPAIR THIS ISSUE AND EVENTUALLY A CHILD SITTING IN THE REAR IS GOING TO GET GLASS BLASTED INTO THEIR HEAD. PLEASE HELP US AND KEEP OUT CHILDREN SAFE!! THANK YOU

MY VEHICLE HAS THE SLIDER WINDOW AND UPON REPLACING AT SAFELITE GLASS THEY SAID THEY SEE THIS FREQUENT ON FORD TRUCKS AND THAT TO PREVENT IS TO EITHER NOT HOOKUP DEFROST WHEN WINDOW IS REPLACED OR NOT USE THE REAR DEFROST.

IT WAS A COLD MORNING AND I SWITCHED ON THE REAR WINDOW HEAT TO CLEAR THE WINDOW. ABOUT 15 MINUTES LATER, AS I WAS DRIVING ON THE HIGHWAY, THERE WAS A LOUD BANG. IT SOUNDED LIKE A GUN HAD BEEN DISCHARGED INSIDE THE VEHICLE. ALL DASHBOARD INDICATORS WERE IN THE NORMAL RANGE. AS I LEFT WORK LATER THAT DAY, I NOTICED THAT THE PASSENGER SIDE OF THE REAR WINDOW WAS COMPLETELY SHATTERED. ALL OF THE GLASS FRAGMENTS HAD REMAINED IN THE WINDOW FRAME. I BELIEVE THAT THE WINDOW HEAT MALFUNCTIONED AND CAUSED THE REAR WINDOW TO SHATTER. I RESEARCHED THE PROBLEM ON THE INTERNET AND FOUND THAT THIS IS A COMMON PROBLEM WITH NUMEROUS COMPLAINTS.

TUNED ON MY REAR DEFROSTER AND LIGHT DID NOT COME ON. I PRESSED IT A COUPLE MORE TIMES AND NOTHING. ABOUT 10 MINUTES LATER WHEN I WAS GETTING GAS IN MY LOCAL CITY IN ALABAMA, IT SOUNDED LIKE A GUNSHOT WENT OFF. I LOOK AND THE PASSENGER SIDE REAR WINDOW PANEL HAS SHATTERED. I DID SOME RESEARCH ONLINE AND FILE HUNDREDS OF SIMILAR COMPLAINTS DUE TO A FAULT REAR DEFROSTER. FORD IS WILLING TO DO NOTHING ABOUT IT, LEAVING CUSTOMERS WITH THE EXPENSIVE BILL. THIS SHOULD BE A SAFETY ISSUE.
