My wife and I were travelling on I-95 (southbound) towards richmond, va. My wife was the driver. We were steadily travelling at a speed... Between 65 and 70 in the left lane (required speed limit). All of a sudden, with no warning, the panel lights started blinking and the power to the car was shut off. My wife was screaming because she was not able to control or effectively apply brakes. She tried and pulled car off the road barely and we pushed it off to a safe side. This could have resulted in a serious accident if we were travelling in the middle lane. The car was left overnight and towed to toyota dealer. The dealer called back and gave a quote of $10000 because the hybrid inverter have to replaced. I mentioned the recall on the inverter. The dealer said the recall does not cover my issue. There is a recall on your website -what action or recourse do I have. The original owner of the car replaced the inverter at 16200 miles. Evidently all the 2006 inverters are defective. My question is this ---why your department is toyota to get away with such a serious defect?

I was driving on a straight highway between 45 -50 MPH. Sudden a bunch of lights and warnings came up in the dashboard. I lost power steering and motor propulsion too. I pressed the accelerator and nothing happened. Although I had the ability to brake, it seemed that the braking was also impaired. However because I was going up an incline I did not need strong braking. I managed to coast over to the breakdown lane. Luckily there were only a couple other cars near me so it wasn't too difficult to maneuver by them and coast to the other side of the road where the breakdown lane was. Once I was completely stopped I shut the car down completely and restarted in the normal hybrid startup manner. The car propulsion and steering came back but now the message was alternating between "maintenance needed" and "check vsc system", and the check engine light and symbol was on. I shut off everything electrical to minimize electrical drain. I was able to drive the car another 8-10 miles to get home but I was constantly looking to see where I could pull over if the car stopped again. I made it home. Tomorrow bring it to the toyota dealer. Significantly, I recently had the brake actuator replaced at a cost of around $2700, specifically because they warned me that I could lose braking and other electronic facilities unpredictably. I thought that expensive repair would avoid this. Unfortunately it appears that what they were predicting could happen did happen, but after the repair! I was on a highway when the car died but with not much traffic and an easy access breakdown lane. Had it been 10 minutes later I might have been on a much busier highway in a place where a breakdown lane is much harder to reach. That would have been a dangerous situation. Had it been daytime and in a safer area I would have stopped and called for a tow truck.

While decelerating to turn into our drive way the vehicle rapidly accelerated. We were able to get it stopped by using the brakes, ending up in the yard/sidewalk. There were approximately 10 feet of skid marks. The engine was racing while the brakes were being applied. The floor mat was not involved. The increased engine RPM was not initiated nor controllable by the operator. This was truly an uncontrolled run away that could have been life threatening.
