Hi I believe that the rav4 have an electric power steering. I have experienced it twice where the power steering did not operate when I started the car. This was definitely not the steering lock as the steering wheel turned as I drove forward but I had to hang on the steering wheel to turn. The only way to engage the electric power steering was to turn the ignition off and start the car again. I asked my Toyota service centre to check it out and was told that they saw some errors logged by the computer but they were not concerned as it must just be a " small computer error". I am however concerned that this may happen at speed. Have anyone perhaps experienced this before. Regards
