Cruise Control problems of the 2008 Toyota 4Runner

Takata recall when cruise control is on and going up a hill, engine jolts and accelerates. Has been doing this since we bought it in 2012.

I was in the smoky mountains in Dec 2009-Jan 2010 where the temperatures were very low and the vehicle was outdoors. Temps were mid 20s in the day time and mid teens at night. No icing was an issue. I was driving my 2008 Toyota 4-runner into a parking space slowly around 2 pm getting ready to apply the brakes. Before I could do so the vehicle took off. I immediately slammed on the brakes and the vehicle did stop, however it had traveled approx 10 ft before I could do so and it slammed into a tree. I owned a new 2003 4-runner and never had this happen. I bought this vehicle in Jan 2008 new. This is the only time this has happened. This crash resulted in $1768. 35 in damage. I took the vehicle to a Toyota dealer and they removed my all weather mats. (I inspected these immediately after the accident and they were in place as they should be locked down) Toyota set up an appointment and looked at the vehicle at the dealership and sent a letter that stated "no system failure was found in either the braking system or the accelerator system" they further stated that "the fact your vehicle is not included in the current safety service campaign involving floor mats/unintended acceleration would indicate that this incident was not the result of this issue. " ??? if not what is the issue. . Cruise control computer ? the dealership stated that the only vehicles affected were made in the USA and my vehicle was made in japan, therefore it was not having a problem. What happens next time and I go off a cliff. We need some answers. I don't know what to do. I spent alot of money on this vehicle and I am not sure it is safe and if I sell it I stand to lose enough money to keep me from buying a vehicle of equal value. We need to put our foot down and make them solve this. Thank you NHTSA.
