“I was driving on a freeway off ramp when the power just stopped. It did not slow but stopped and I managed to pull over. The warning signals all came on and so I could not look up the problem. Since then they say there is a problem with the inverter but the dealer will not fix it even though we are under the original warranty as well as buying an extra certified platinum warranty for $2000!”

“I was traveling on an interstate highway using cruise control and going about 72mph. The Prius suddenly shut down. At first I thought I had bumped the cruise control so I tried resetting it but nothing happened. I stepped on the gas and nothing happened I continued to slow down. Made it to the side of the highway where I sat wondering what had happened. After shutting the car down I restarted it and it seemed to be ok so I continued my trip. Never forgot the episode.”

When the car ahead started moving, I put my foot onto the gas pedal but the car would not move. All that I saw on the dashboard was a light green long arrow pointing left (not the turn signal higher on the dash). I managed to roll into the left shoulder. I never turned off the car but at that point put it into park. (before that I had not touched the gear shift.)called 911. …”

“I frequently get a musty smell out of my vents that I have noticed from time of taking ownership. I was told at that time Toyota was aware of it and the solution was to take the system out of recirculate a few miles from home allowing outside fresher air in to remove the apparent moisture buildup. I tried to leave the system in the fresh air mode most of the time, but still experience this smell/odor. At my 10k service I brought this up again and was offered a 'goodwill' system cleaning and a charcoal filter. …”
