2016 Toyota Tundra service brakes problems

“The trailer brake controller went out. It does not supply electronic braking and the truck no longer recognizes the controller on the dashboard. Multiple on line chats and forums, along with my trailer provider, show awareness of this defect. Online individuals learned of the issue during emergency stopping. This appears to be known and wide spread.”

“1)Over 60 MPH with new tires the vehicle pulses & shakes on front end, checked alignment everything OK per Mechanic. Just started to occur 2)Bluetooth when on iPhone will at any time cut out guaranteed to occur when using at any time been occurring for 2 + years. 3)Trailer brake warning light (Idiot light) comes on dashboard does not recommend trailering due to electrical issue. occurring for 2+ years Bought vehicle used in 2017 with 13k on Truck now 2024 has 91K on truck love the truck but zero recalls for any of the above?”

“Bought a used 2016 Tundra, unaware of the massive problem they have with their intergrated brake controller, i feel they need to do something about this or reimburse the buyer for buying a aftermarket one to replace the factory unit. Its a very unsafe problem when pulling a trailer, I love the truck otherwise but this issue needs fixed.”

“INTEGRATED TRAILER BRAKE CONTROLLER INTERMITENT FAILURE. TRAILER BRAKES WORK FOR A FEW BRAKING CYCLES THEN FAIL COMPLETELY WITH AN ERROR MESSAGE ON THE TRUCK OF "TRAILER WIRING TYPE, OR CONNECTION FAULT". TURNING THE VEHICLE OFF AND ON RESETS THE CONTROLLER AND "FIXES" THE PROBLEM UNTIL ANOTHER FEW BRAKING CYCLES, THEN REPEATS.”

“THE FACTORY SUPPLIED OEM BRAKE CONTROLLER DOES NOT FUNCTION PROPERLY, AND IS A SIGNIFICANT SAFETY ISSUE. THE CURRENT DESIGN OR SOFTWARE IS TOO CONSERVATIVE, AND DOES NOT PROVIDE SUFFICIENT POWER TO TRAILERS WITH ELECTRIC BRAKES. I HAVE TOWED MY NEW TRAILER WITH NEW BRAKES SEVERAL TIMES, AND THE RESULT IS CONSISTENT. WITH THE BRAKE CONTROLLER SET AT FULL POWER, THE ACTUAL TRAILER BRAKING IS MINIMAL, THEREFORE FORCING THE VEHICLE TO PROVIDE SOME OF THE BRAKING FORCE. THIS WORKS IN CONTROLLED SITUATIONS ON LEVEL GROUND. BUT, IN THE MOUNTAINS OR EMERGENCY STOPPING, THIS REPRESENTS A SAFETY ISSUE WHERE I DO NOT FEEL THAT THE VEHICLE AND TRAILER WILL BE SAFELY STOPPED WITHOUT INCIDENT. A FRIEND OF MINE HAS THE EXACT SAME VEHICLE WITH THE EXACT SAME ISSUE. A SIMPLE INTERNET SEARCH WILL REVEAL HUNDREDS OF SIMILAR COMPLAINTS. THIS ISSUE STARTED WITH THE 2015 MODEL YEAR. I'M CONCERNED THAT TOYOTA IS CONTINUING TO IGNORE THIS ISSUE DUE TO LEGAL LIABILITY REGARDING ACCIDENTS THAT ALREADY OCCURRED DUE TO THIS ENGINEERING FLAW. IT IS GOING ON 3 YEARS NOW WITHOUT A FIX. TOYOTA DID ISSUE A SOFTWARE UPGRADE LAST YEAR WHICH SHOULD HAVE FIXED THIS ISSUE. I HAD THE UPGRADE DONE,…”

“I PURCHASED A NEW TRAILER TO PICK UP MY NEW TRACTOR. I TESTED THE TRAILER BRAKES KNOWING I WAS PULLING A LARGE LOAD AND DIDN'T WANT AN ACCIDENT. THE BRAKES APPEARED TO APPLY BUT DUE TO IT NOT BEING LOADED WHEN TESTING I HAD IT SET TO 5(OUT OF 10). WHILE PULLING IT BACK HOME ON THE INTERSTATE TOWING MY TRACTOR BEHIND ME THERE WAS TRAFFIC STOPPING AHEAD. I ALWAYS DRIVE IN THE RIGHT LANE TO NOT SLOW OTHERS...THANK GOD I DID. I HAD TO DRIVE OFF THE ROAD ONTO THE SHOULDER TO MISS HITTING OR DRIVING OVER CARS AHEAD OF ME! THE BRAKES TURNED UP TO 10 DID NOTHING TO EVEN SLOW ME DOWN. I WAS TOWING 4 TONS AND 3 TONS FOR THE TRUCK TOTALING 7 TONS, SOMEONE WOULD'VE BEEN KILLED! TOYOTA NEEDS TO FIX THESE TRAILER BRAKES! I CAN'T TOW MY TRACTOR ANYWHERE FOR WORK DUE TO THE BRAKES BEING UNSAFE!”
