Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

As I left work my indicator showed a full battery all bars in blue. As I was driving down the coast I noticed the battery started to quickly deplete, in approx 8.6 miles my indicator showed 1 blue bar. At that time I was making a left onto the canyon road. I thought this was odd. As I turned left noticed a decrease in acceleration power. Didn't think much of it but about until about 2 miles in I noticed the Prius started losing acceleration power the motor was running and the indicator did not show that it was in ev mode even coasting through the canyon and braking. I had to accelerate to come up a slope through a tunnel I had almost no acceleration power. The car felt like it was hesitating I think by the down hill coast and a few spurts of power surges I was able to make it through the tunnel by the 5th mile I had no power to accelerate luckily there was a road where I could make a right. As I coasted to the intersection I turned right then attempted to pull a uturn on a patch of dirt as I was 3/4 of the through the turn there was zero power the vehicle was on but no power engine cut out. No check engine light whatsoever I got suck in the middle of the 2 lane highway blocking both directions! I put on my hazards and attempted to put the car in neutral it indicated it was in neutral, then I shifted to drive but again no power the car was just making a noise and like a very faint grinding noise. At this point cars were on both lanes trying to head each direction I had to get out and push the car backwards to get 1 tire off the side grade then I was still sideways in the middle of the road. I cycle the car 3 times by putting it in park with parking brake with no luck, or power. It wasn't until 4th try it got some power the engine kicked on and I was able to pull back in the right lane and I was stuck at the corner with my hazards on.

The 2016 Prius 4 doesn't come with the ability to change miles to kilometers unless you are aware that it is an option you have to buy which neither salesmen or Toyota technical assistance is aware of. I have not been able to find anyone who can tell me whether this option can be added but so far it appears that it is.
