NHTSA Complaint #10872503 — 2015 TOYOTA TUNDRA

I OWN A 2015 TUNDRA CREW CAB. THE FAMILY AND I LOVE TO CAMP, SO WE PURCHASED A BRAND NEW CAMPER. I HOOKED UP THE CAMPER TO THE TUNDRA UTILIZING THE 7 PIN CONNECTOR. THE DASH DISPLAY INDICATED THE INTEGRATED BRAKE CONTROL WAS WORKING AND FULLY FUNCTIONAL. TO MY DISMAY, THE BRAKE CONTROL DID NOT WORK TO SATISFACTION AND BORDER LINED A SAFETY ISSUE. WITH THE GAIN TURNED UP TO 10 ON ELECTRIC MODE, THE CAMPER'S BRAKES BARELY ENGAGED AND RARELY SLOWED DOWN MY TRUCK. THE CAMPER IS 7800 POUNDS. I HAVE BEEN READING FORUMS AND OTHER TUNDRA OWNERS ARE HAVING THE SAME ISSUES WITH THEIR IBC....THERE IS NOT ENOUGH BRAKING POWER WITH TOYOTA'S FACTORY IBC. SEVERAL TIMES GOING DOWN HILL I DID NOT THINK THE ELECTRIC BRAKES WERE GOING TO SLOW TO STOP MY TRUCK! MY TUNDRA DID ALL THE BRAKING. I ALWAYS HAD MY FAMILY IN THE TRUCK WITH ME. IS THERE A RECENT SERVICE BULLETIN OR UPDATE TO THIS CONTROLLER???? AFTERMARKET CONTROLLERS WORK MUCH BETTER, BUT I WANT A CLEAN LOOK TO MY CAB. THANK YOU
