    My Prius 2007 switches to neutral or park while in motion. I have a couple of codes C1241. Sometimes the screen displace 12v battery and check hybrid when it happens. But immediately I turn the car off and back on the screen returns to normal and it drives. Again, I noticed my 12v battery drains doesn't charge when I did the self diagnosis on the monitor. I bought another new battery it's the same issue. What could be the problem. I've also changed the gear sensor.

    You said you have a couple of codes but only listed one? What's the other code?

    As for the photo, that happens when driver's door is open and car is in drive. Not related to your probelm.

    Main concept to understand here is car goes into neutral when it has something seriously wrong with it... I suspect both your 12v and your hybrid battery got problems.

    If the car door is opened when in DRIVE, the CAUTION screen that appears tells you to shift to the P position when parked. Along with a blurb about batteries not charging if the shifter is in Neutral.
