Can an automatic car roll forward when the engine isn't running and geared on park? Lexus ls430 20
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.
