2010 F-150 Ford truck suddently brakes to the right or left abruptly slowing the vehicle and causing the vehicle to veer to the right or left. First occurance June 29, 2011. The traction control light comes on on the dash. Following instructions in the owners manual to turn the traction control off does not work. Instance happens most often when turning. Sudden slowing and veering in intersections almost have caused 2 accidents. The vehicle was taken/driven to the dealer on July 1, 2011 and the dealer advised the defect was repaired. Reaccurance on July 6 & 7--- vehicle returned to the dealer and I was advised the vehicle was repaired upon return of the vehicle on July 8. Reaccurance on July 15, today. I will seek repair at another dealer. This is a dangerous defect which I fear may cause an accident.
