Prime rolls when put in park even in small incline

I assume you mean that it might roll forward or backward an inch or two until the parking pawl "catches." This is normal behavior for many cars. However the car should not continue to roll past an inch or two. In the photo below, you can see that the car may need to move forward or backward after park is initiated due to the design of the gear that the pawl engages.

I always keep my foot on the brake, push park (which engages the pawl) and then engage the parking brake. That will eliminate the behavior.

 

Have you driven any previous Prius? This is not different than my two (past and present) Gen3s, and I believe earlier generations were similar.

I always use the parking brake on my household's manual transmission cars, and haven't owned a 'normal' automatic in more then thirty years.

 

I've never had a vehicle (of any description) that wouldn't rock back and forth an inch or two, when off, in park, without parking brake on.

 

As one who just had a pLock actuator replaced, my current approach on a slope is to stop the car with the foot brake, apply the foot actuated parking brake, release the foot brake, then hit the P to lock the parking pawl that locks the transaxle and then power off the car. My failure occurred when I first used the pLock to hold the car before putting the foot actuated parking brake on. The entire car's weight was resting on the pawl and then its retraction wasn't effected by the actuator.

Granted this is on a v but isn't the principle the same?

 

I went out for a drive to check my description through the application of muscle memory. I do exactly as you do (not the way I previously described). I ALWAYS use the parking brake, even if I am on the flat.

 

Always use the parking brake, do not rely solely on the parking pawl.

And, I concur, I've never driven an automatic that WOULDN'T rock a couple inches before the parking pawl engaged, if you didn't set the parking brake.

 

I just switch off the car and that puts it into park for me. If on an steep incline I also use the parking brake.


iPhone ?

 

yes, prius can roll more than a few inches after putting in park. i always make sure to take my foot off the brake slowly, until it has come to a stop.

 

This happens on every other automatic I've ever driven from 1972 to 2012 model years. It has to because of the way the parking system works.

 

The Toyota automatics seemed to have more give in park than our GMs and Fords, and the Prius more so. With the Prius, I'm now in the habit of using the parking brake with all my cars.
