The parking pawl should prevent the car from rolling any significant distance, but if the parking gear is worn/missing teeth the pawl won't have anything to grab. You don't say how far forward it's rolling - a lot or a little? The correct way to put a car in park is shift into neutral, set parking brake, then shift into park. Most people never do that, and parking brakes love to hang up. Have a mechanic look at the pawl/parking brake if it's a problem.

Thanks for your response KenF. The car rolled several yards down a slight hill and ran into a garage. I'm just trying to figure out how this could have happened with the engine off.


We have a Toyota Sieana 2011. When I shut off the car in gear (forgot to put in Park) the car rolls forward or backward depending on hill slope. I expect that when left in gear and engine off, it should not move.
