Brake Sensor problems of the 2013 Toyota Tacoma

I have been running the same wheels and tires on the vehicle since it was brand new, running 17" aluminum wheels with a 10- ply rated 265/70/17 michelin lt which is a standard size for this vehicle. At about 47,000 miles the traction control on my Tacoma started acting up badly making it very dangerous to drive on mountain roads with super-elevated turns. Basically the truck thinks it is sliding when it's not even close to breaking loose at 35 mph. The sensors or computer is failing causing the right front or left front wheel to pulse (apply brake pressure) which results in the vehicle pulling in the opposite direction I am steering. This is at low speed 35 to 40 mph. This is a very dangerous situation and I explained that the vehicle is 'pulling me across the center line into on coming traffic which could cause a head on collision and I got no response other than " if my shop foreman tells me the truck is operating as designed there is nothing more we can do or you. When I called it to the attention of the service manager and shop foreman at northridge Toyota, I was told the vehicle shows no errors so the truck is "operating as designed' and their suggestion was to deactivate the traction control from now on, each time I drive a mountain road. I explained that they were asking me to deactivate the on board safety measures on the vehicle in order to drive the truck in the highest risk driving conditions, they again said the truck was operating as designed and that I should not expect their to be any repairs made. This is absolutely inexcusable. They went on to suggest I seek a second opinion at another dealer and they sent me down the road in my truck even though I told them the symptoms, duplicated the problem with shop foreman in the truck and most importantly that the truck was unsafe to drive. Fascinating!!!.
