My Prius is staying in battery drive when fully stop, it started about 2 wks ago. I will be stop for 3-5 even 10 min and the battery mode will keep feeding power to the wheels when not even moving & brake pedal press fully down & engine is off & battery starts to drain. In order for it to stop I have to take it out of drive & put it on neutral. When you come to a complete stop, you usually won't see any energy flow unless the battery gets low & engine comes on to charge it but my battery is full when this happens. Any info what can be causing this? Also my front left tire locks when I press on the brakes & takes longer to stop & this started at the same time as the one mention above. *Im not sure if this could be a cause to the problem but about 3 wks ago we had Hurrican Irene & since my house is next to the river it started to flood. I moved the car the night before it hit about 2 blocks away but in the morning when I woke up there was water all over. I rushed to my car and the water was below the door sill & just a little bit of water got on the bottom of carpet (you couldn't see it but if you touch the carpet it was wet in some parts) so I move the car to higher ground, no problem when I started the car or any lights on dash. I drove the car for about a week with no problem & the following wk is when the problem started, so Im not sure if this could've cause the problems Im having now.
