    Not sure if this is a common issue. I have a 2020 AWD-e LE model.
    It now has about 5k miles.
    I've noticed that when I am arriving at my destination and put the car in park and turning the car off, there is more than a little roll that occurs and it seems like a loud noise is coming from the transmission.

    It seems like I have to put the parking brake on every time I park now to keep the roll from being too pronounced.

    Is this a common issue? Is something wrong with my drivetain?

    Not sure if this is a common issue with CVT as opposed to the 1999 Honda Accord I had previously and I should just accept it.

    Thank you for any insight.

    I have a 2018 Prime and rocks a little forward or backwards. Maybe a inch at the most.

    That is the purpose of the parking brake. You should not depend on the park pawl in the transaxle to hold all the weight of the car.

    That's normal. There's quite a bit of space between the slots that the parking pawl drops into. All my Prii have rolled up to 3-4 inches before it engages. For maximum stability, let it engage and then use the parking brake. As for me, I only use the parking brake on steep hills or if I'm going under the car, in which case I also chock the wheels. See the picture in post #2 here. Prime rolls when put in park even in small incline | PriusChat

    Have you tried putting it in "P" before you turn it off ?

    Yes, I do put it in P before turning the car off. In reading the above comments and the other thread referenced above, it appears there is more give with a Prius.

    Is this the correct order?

    Foot on brake
    let car come to stop
    Press P
    Activate Parking Brake
    Foot off brake
    Power off

    what would be the order when starting to drive again?
    turn car on
    foot on brake
    release parking brake
    move to D
    begin driving

    You need to put your foot on the brake before turning on the Prius.

    I usually just turn the car off if I'm on the flat. If I'm on a gentle slope, I stop with my foot on the brake and put it in "P" before turning it off, slowly releasing the footbrake. I can't say I've ever had the car roll, maybe just a little rock, when on a slope, now and again. I only use the foot operated parking brake if I'm on a steep slope or if I haven't used it for a while just to prevent it seizing up.
    My new car, the MG ZS EV actually puts the parking brake on when you press "P" rather than a pawl (no gearbox).

    Except for special situations, my sequence is:
    Stop the car.
    Push the start button to turn it off.
    Exit the car.
    (Edit to add: I guess I drive at least twice a day, 6 days a week. Probably more. So, in 6+ years of Prius ownership, I've had over 3,700 start stop cycles with no issues.)

    Assuming the parking brake isn't set:
    Put my foot on the brake.
    Press the Start button.
    Put it in drive. (or reverse as needed)
    Go.

    You're probably more likely to have a wheel fall off when driving that to have the parking pawl let go. In fact, I personally know someone who had two wheel fall off at the same time, but don't know anyone with a pawl failure.

    I had one fail on an old Dodge Dart. The parking brake was not very good either. For a while I stopped and quickly used a brick to chock a wheel to stop it from rolling.

    Yeah, but that's a Dodge. Does it really count? :ROFLMAO::ROFLMAO::ROFLMAO:

    Those old slant six engines ran forever.

    This is true!!! I gave up my old Dodge Ram 2-door "SUV" when I decided there was too much danger of falling out the bottom of it. But the slant six was ready for lots more service.

    LOL When I married my wife she had a Dodge Ramcharger. Steering linkage kept getting worn on that 4WD Utility Vehicle.

    It should be this: (regardless or grade or incline)
    Complete stop with Brake Pedal
    Hand Brake/e Brake
    Shift to P
    Turn Car Off.
    Foot Off brake
    Exit.

    I do the Hand Brake first because that want hand brake to hold the car. Brakes easier & cheaper to replace than transmission.

    Start a Car,
    Foot on Brake Pedal
    Start Button
    Off Brake pedal
    Adjust Music.Radio, etc
    Check mirrors in case a family member had a joy ride
    Brake Pedal
    release Hand / E Brake
    Shift to R or D
    Off you go.
