I was driving my Toyota Sienna on a busy 6 lane highway in the second to the left lane, on a bridge. Suddenly without any warning at all, my vehicle lost all power and came to an abrupt halt in the middle of high speed traffic. My wife and children were all in the car and we were in imminent danger of getting hit by another vehicle. It took the police approximately 10 minutes to arrive during which we were in life threatening danger. After the vehicle stopped a message on the dashboard read hybrid system failure. The police tried to push our vehicle to a safe spot but the wheels wouldn't turn and the car had to be towed. Upon inspection by the mechanic it appears that there is a broken shaft in the transmission that may have caused this problem. I want to emphasize that there was no warning at all and we did not have a chance to move to safety.
Sound coming from engine / transmission other issues with the 2 ruber seals on the minivan keep worping out I looked on all the forms everyone is making the same complaint I toook it to Toyota they just put tape and its off again they didnt help for a perminent fix back door is miss alined pasanger side sliding door sometimes does not close takes 3-4 atempts pressing the button.
Check engine light came on - taken to dealer, diagnosed following 2 codes : p24517f and p14502a both of these codes are known problems to Toyota, and as such a service buliten for the evap emission system switch valve has been issued per NHTSA. This problem should be a recall, not a known service issue - it is obviously a common problem with Toyota in the hybrid engines.
There has been several incidents when I step on the brakes and the vehicle seems to accelerate forward after what feels like an attempt to find the right gear when decelerating. This occurs infrequently but usually when decelerating along with an external factor. I was able to consistently replicate when I’m coming off the highway onto a service road then have to make quick turn at a corner. It feels as if the vehicle is trying to search for a gear and once it finds it there’s a momentarily acceleration forward.
About 25% of the time when I come to a stop and I am breaking, the car surges forward slightly. At first, I thought it was the way I was driving or the fact that it is an ev vehicle, which I had not driven before, but overtime it seems it is just the way the car operates. Others in the car have felt it happen as well as I have come to a stop sign or stoplight. I have not bumped into another car or anything but feel that that could happen if this is not corrected.
