Steering Wheel Vibrate problems of the 2001 Toyota Sequoia

My 2001 Toyota Sequoia violently experienced a vsc trac error when driving next to a semi on the freeway. It almost pulled my car into the semi, and then off the road as the wheel jerked, brakes and engine response cut significantly. This highway issue happened last month, and just this week, the problem has become more frequent, occurring on neighborhood streets with absolutely no triggers. The steering wheel sometime shakes, and sometime pulls suddenly. It occurs sometimes during a slow turn, but is also happening just driving at 25 miles an hour down a straight road.

Having issues with stopping a 2001 Sequoia due to undersized braking equipment. The issue is when the brake is depressed the Sequoias tires and steering wheel shake excessively. I have replaced the pads and had the rotors turned. This is know issue with the Sequoia for Toyota. TSB issue and braking system fixed as long as the car is under 36000 miles this is a safety issue to all drivers on the road. I have had a couple near misses due to the inconsistent breaking. While at dealership (Toyota of concorde in nc they will not even acknowledge the ts"s are out there. It is an ongoing safety issue that when coupled with issues with the traction control that is going to seriously injure or kill people. As stated the brake issue has cause near misses in our SUV and other.
