NHTSA Complaint #11431034 — 2021 FORD F-150 HYBRID

THE TRAILER BRAKING SYSTEM ON MY NEW 2021 F150 POWERBOOST MALFUNCTIONS EVERY ONCE IN A WHILE. WHILE TOWING MY 27 FT AIRSTREAM TRAILER THE BRAKES WILL OFTEN STOP WORKING. THEY ALWAYS WORK WHEN I BEGIN A TRIP, BUT THEN THE BRAKES FAIL DURING THE TRIP. I RECEIVE A NOTICE WHEN ATTEMPTING TO MANUALLY APPLY TRAILER BRAKES FROM INSIDE THE CAB THAT THE TRAILER IS NOT RECOGNIZED. SEVERAL OTHER NEW F150 POWERBOOST OWNERS ARE EXPERIENCING THE SAME ISSUE AND THEIR EXPERIENCES CAN BE FOUND ON THE F150GEN14.COM USER FORUM. I HAVE INCLUDED A LINK TO THE FORUM THREAD. https://www.f150gen14.com/forum/threads/trailer-brake-not-working.3039/ SO FAR NONE OF US HAVE ANY SUCCESS WORKING WITH FORD DEALERS. I HAVE TRIED SEVERAL AND THEY ARE NOT HELPFUL. I ALSO CALLED FORD CUSTOMER SERVICE BUT THEY COULD NOT FIND ANYTHING IN THEIR DATABASE INDICATING THERE IS A PROBLEM. THE ONLY CLUE I'VE FOUND SO FAR, FOR MY TRUCK, HAS TO DO WITH THE SEVEN PIN PLUG. WE HAVE TRIED TWO DIFFERENT TESTING DEVICES AND BOTH SHOW THERE IS ABOUT A 6 SECOND DELAY SENDING A SIGNAL TO THE EBRAKE PIN. THE OTHER PINS FOR LIGHTS FIRE IMMEDIATELY, BUT THE EBRAKE PIN HAS A DELAY. OTHERS ARE LOOKING AT THE BRAKE MODULE IN THE TRUCK AND OTHER PROGRAMMING ISSUES. AS YOU CAN SEE FROM THE USER FORUM THERE ARE MANY THEORIES AND NO SOLID SOLUTIONS YET. I HAVE HAD MY AIRSTREAM BRAKES INSPECTED TWICE AND THEY HAVE NOT FOUND ANYTHING OUT OF THE ORDINARY. THIS IS A SERIOUS SAFETY ISSUE BECAUSE A 7K LB TRAILER PUSHING YOU DOWN A STEEP MOUNTAIN WITH NO BRAKES IS TERRIFYING. SOMEONE IS GOING TO HAVE A SERIOUS ACCIDENT IF FORD DOES NOT TAKE THE ISSUE SERIOUSLY AND FIND THE CAUSE.
