Cruise Control problems of the 2010 Toyota Tacoma

While driving in northern kentucky on a slight incline in hilly country southbound on I-75, I disengaged cruise control when a vehicle pulled in front of me. When vehicle moved off the highway about 15 seconds later, I re-engaged cruise control (at approx 65 mph) at which point the vehicle accelerated on its own to over 85 mph. I then disengaged cruise control and the vehicle normally decelerated. The exact same thing happened two (2) months earlier while traveling on an interstate in north carolina under the same circumstances (elevation around 2500-3000 ft on an incline). I reported this to the Toyota dealer last week and they said there is a recall to "reflash the computer" on my 2010 Tacoma v6. I have seen no reference to such a recall on Toyotas website for my VIN.
