NHTSA Complaint #11184319 — 2018 FORD F-150

FORD 2018 F150 REAR WINDOW / DEFROSTER ISSUES - LUCKILY, MY REAR WINDOW DID NOT SHATTER AS OTHERS HAVE EXPERIENCED, BUT I HAVE EXPERIENCED DEFROSTER OVERHEATING TO THE POINT WHERE 2 OUT OF 3 SECTIONS OF THE WINDOW NO LONGER WORK. UPON INSPECTION, IT APPEARS THE RESISTIVE ELEMENTS ARE BURNT AND BECOMING DELAMINATED FROM THE WINDOW IN MULTIPLE PLACES. I DID ALSO SMELL WARM/BURNING ELECTRONICS AT THE TIME IT HAPPENED. I TOOK THE TRUCK TO THE DEALERSHIP - AS THIS SHOULD STILL BE UNDER WARRANTY, BUT WAS TOLD THE CLAIM WAS DENIED, EVEN THOUGH I DID NOTHING TO CAUSE THIS AND THEY COULD NOT TELL ME WHAT HAPPENED. I CAN SEE HOW A SUDDEN OVER-CURRENT / OVERHEATING LIKE THIS COULD LEAD TO GLASS SHATTERING AND FORD SHOULD BE HELD LIABLE IF THEIR CONTROLS AND/OR DEFROSTER ARE NOT WORKING PROPERLY. IT IS ALSO DANGEROUS, AS MY VISION IS OBSTRUCTED AS A RESULT OF THIS ISSUE. THIS MOST LIKELY HAPPENED WHEN THE VEHICLE WAS STATIONARY, DURING WARM-UP, USING AUTO-START.
