 Drove 850 miles to P/U a TT. Within a mile I found out the integrated brake controller didn't work at all no matter what setting it was set at. The manual slide does work. Drove all the way home without the IBC. Thanks Toyota! What a let down. Did some research when I got home and found out none of the IBCs work on the 2016 Tundras. Do an online search and you can read all kinds of complaints but Toyota has not even acknowledged it yet. With all the documented problems, what's going to happen when someone unknowingly starts down the Hwy thinking he has trailer brakes and ends up with someone being killed. Who's gonna be at fault? Toyota, you better get this fixed and fast!
