Call SOA and make a note of the issue. With Toyota's problem with unintended acceleration, I would think they would follow up on it. If it happens to happen when you're close to a dealership, bring it in right away. The ECU on this car has a data event recording system that can capture certain data points such as speed throttle position and other pieces of data, but only for a short period of time.
At the very least, you need to document it.
