The 1st time this occurred I had a trailer in drive and it rolled backwards breaking a taillight in a jack-knife situation.  I took the vehicle to my dealership were the vehicle was checked and no problem was found.  They refused to replaced the tail light as no problem was found.  The 2nd time was in congested traffic moving at a snails pace.  On a steep hill stop and start traffic.  When I slowly applied throttle the vehicle \"Hill Assist\" disengaged and the vehicle rolled backwards.  Appling more throttle finally caused the transmission to engage.  Now knowing how this occurred I was able to recreate again and again.  I again took the vehicle to my dealership even taking my salesman and the service technician on test drives showing them the safety concern.  I was again told that no problems were found.  I then took my wife on a test ride to show her how the vehicle could roll backwards on a hill in stop and go traffic.  During this drive once the vehicle not only started to roll backwards but when the throttle was depressed more the vehicle stalled and continued to roll backwards until i moved my foot from the throttle to the brake.  As the engine was off additional effort was required in depressing the brake.  The steering was also harder to turn.  Had I rolled an additional 12 feet I would have backed into a retaining wall on the passenger side.  My wife has decided to take a different routes to avoid hills that have stop and go traffic.  I called Toyota filed case # 220407001182 which they declined to repair the taillight and told me that the vehicle operated as designed and no problems were found.  They did tell me if I felt the vehicle was unsafe not to drive it.  They indicated they would not provide documentation on the decision. Owners manual doesn't indicate vehicle can roll backwards as \"Hill Assist\" disengages.
