Unexplained acceleration caused vehicle to exceed posted speed limit and driver's desired speed. On a city street at approx 7pm I was increasing speed after sitting at a stop light, I slowly started to accelerate, I felt a jolt & vehicle suddenly picked up speed. Not knowing why this was happening I repeatedly pushed the cancel button on the steering wheel & pushed the brake pedal. Vehicle continued to pick-up speed when I stopped pushing brake pedal. I came to a complete stop & vehicle went to picking up quick speed without me pushing accelerator pedal. I pulled into vacant parking lot, put vehicle in park, removed my foot from brake pedal & vehicle accelerated high (rpms) by itself for a few seconds & stopped (went to normal idling). I turned vehicle off, restarted & the vehicle drove normally afterwards. I have reviewed owners manual & can't figure out what I may have done to cause the unexpected vehicle acceleration that pushing the cancel button on the steering wheel and/or pushing the brake pedal wouldn't turn off. I was not attempting to use speed control functions of the vehicle. Standard driving. I believe it was a vehicle malfunction and not driver action that created this unsafe situation. Thankfully surrounding traffic was light on what is typically a busy street.
