Summary of Complaint
Integrated Brake Controller (IBC) not sending sufficient power to electric dual-axle travel trailer brakes producing weak if any braking ability. On the approach to the first red traffic signal, there was zero braking from the trailer requiring full braking from the tow vehicle risking a crash. The IBC is providing no warning or failure indicators to the user. The vehicle and IBC are available for government inspection. The travel trailer in use is a 2022 Jayco Jay Flight SLX8 212QBW. While towing a 5,000 pound dual-axle travel trailer for the first time since I purchased the truck brand new from Toyota in 2017, I attempted to setup the IBC. Instructions say to set Type, which I set to electric brakes matching the trailer, then adjust the gain up while travelling around 25 miles per hours. When lock up of the trailer brakes occur, reduce the gain slightly to prevent full lock up. At a Gain of 10 (10 is the maximum), I could not achieve brake lock up and could only obtain weak trailer braking. The trailer was tested with a different tow vehicle and there were no problems obtaining lock up at mid-range gain. I had Toyota inspect the software updates to the IBC on January 14, 2022 and Toyota advised the IBC is up to date on its software and functioning correctly. The Tundra is out of factory warranty, but since I did not own a travel trailer during the warranty period, there was no way for me to test the IBC before going out of warranty.
