“The vehicle suddenly lost transmission on the road and was rolling freely. The gears does not work anymore and the vehicle rolls as if its in neutral. When search the internet I looked at lot of the customers complaining about exact same thing, about this vehicle having transmission issues especially for RX300. No wonder toyota has this many recalls and surprised that their premium brand has the same issues with safety. I am glad that this did not happen on a highway”
