    Toyota had a recall on the Gen 4 cars because they under some circumstances the car would move - drive itself forward without a driver in the car.

    It is darn easy to do with cars using the Start/Stop buttons instead of keys. Here is an example: you are driving to your mailbox, your car keys are in your packet sharing the key ring with the key to the mailbox. You stop the car, press the (darn) foot break and leave the car, door open etc. to make the two steps to the mailbox while fishing out your key ring from your packet to open the mail box. Now the car is in "D". If that (darn) foot break is not properly pressed down the car can "creep".

    I just read GM fixed this problem in the Bolt. The system software senses if there is no one in the driver seat or the seat belt is not fastened. If so the software will put the car into Park. What a brilliant fix and cheap!

    I have no idea how Toyota fixed my car. But a few lines of code seems an easy answer.

    what recall? why wouldn't you put it in park? would you leave a gasser in drive and get out with the footbrake on?

    Agreed. WOW. I have never heard of anyone deliberately getting out of a car that was not in park unless they wanted it to move while they weren't in it.

    The bolt has a confusing shifter. The Prius has a button. A button. It can't get much simpler than that! On my car they added a notch to the parking brake line to make the brake stay in place.

    If you are talking about a computer code, no.

    You'd have to really try HARD for this scenario to happen. If you open the door - it beeps, and shows a big red door on the display. If you did get out and walk away from the car, it starts moving immediately and would likely run you over before you got to the letter box.

    There was a recall on the handbrake (foot-hand-brake thingy - the logic of it escapes me) to install an extra clip - I had mine installed this week.

    FWIW, I thought plugitin missed a gear between brain and mouth and thus, got his foot brake and parking brake confused. It certainly made a bit more sense then.

    Yes the parking brake recall fix did help. I noticed before the fix, in cold temp you start the Prius and the petrol engine kicks on. And if you did NOT have the parking brake on it would move forward. Now it's ok. But the passenger airbag recall is upsetting. Toyota should have addressed this issue before letting the 2016 Prius off the assembly line. Anyone get the fix yet.? If so did your dealer put the dash back ok?

    I also had the airbag done and they put everything together well.

    there is at least one thread here on people that have had the airbag recall done.

    i rarely use the parking brake, but i have my foot on the brake when the engine starts.

    No it wouldn't move, because you'd have your foot on the footbrake when starting. Starting the Petrol Engine has nothing to do with it, as, if you took your foot off the footbrake, it would creep forward whether the Petrol Engine is running or not.

    That's ODDDDD!! It came up as a new response on my list of Alerts this morning - so I responded - didn't check the date.

    Now that I checked - it wasn't a response at all - just someone, 6 months later, responded with a upload_2017-9-14_11-18-18.png .

    Possibly - I couldn't get into PRIUSCHAT most of yesterday - kept getting errors. Working fine today.
