Car Moving With Park Brake Set

[upsidedown]

Just wondering if anyone elses car does this:

1. Come to a stop with foot on brake pedal, car still in gear and then set the park brake
2. With the car still in gear take foot off the brake pedal
3. My car moves slightly forward until the park brake takes up even though the brakes were applied prior and the
car was stationary

On all my other cars with non electric activation when the park brake was set it didn't move one bit

I'll get the service guys to check it but just wondering whether this is common

Same happens to me. Foot on brake, set EPB, put car into Park, ignition off, foot off brake. Car still moves slightly. I think it’s normal.

 

[AV8R]

It’s normal

 

[Ozstung]

Normal, been mentioned around these traps before.

Why are you setting the parking brake before putting it in park?

It could be because you’re still in gear. Once you let your foot off the brake for a split second drive will try to move the car until it realises the park brake is set, you’ve got two systems competing against each other hence the slight movement until the computer figures it out.

Put it in park first, then set the park brake, then let your foot off the brake pedal. I do it in that order and my car has never moved.

You have to set lever in neutral then hit brake button.

It is a bit different on the Stinger I noticed. I'll have to test to see if it does the same on my Optima but I typically go the park, then apply the brakes.

"Moved" is relative or even subjective. I feel a very slight settling in, rather than anything I would call a "movement". Put the car in "P", engage the electronic parking braking. Take my foot off the brake. It settles in, which is an ever so slight sensation of movement about as noticeable as if someone nudged the car from behind with their knees.

Thanks so it sounds normal at least for this car

Just to respond to some other replies:

I normally set to park first and then park brake but the car moves whichever way I do it

As above this is how I normally do it and mine moves. I'm not quite sure why it has to "realise" the park brake is set when the normal brakes should already be applied and stopping the car from moving. I mean the car is already stopped with the normal brakes applied so when the park brake comes on it should just lock them on hence no more movement

You have to set lever in neutral then hit brake button.

I suppose I could do this and I'm sure it would work (will try tomorrow) but it seems a bit unnecessary

With the fly by wire gear selection there is no park to move to, you only have D,N,R

Um isn't the big button with a "P" on it for park?

Yes that’s what I meant but everyone is saying you move the lever to park.

Hehe.. actually, you're the *only* one to refer to a lever in this thread until now.

In any vehicle, when coming to "full stop" (parking for non-aviator types ), you should be leaving one foot on the brake pedal while "securing" the vehicle from movement. For a manual, that's shifting into 1st or reverse with the clutch down and applying the parking brake, in no particular order, but typically you shift first. With an automatic, you should always put the transmission into park (whether that's a button or a mechanical lever) THEN apply the parking brake.

Only after completing these steps should you release the brake pedal.

This is covered in the manual.

Yep that's how I've been doing it for 40 years but whatever the reason this is the only car I've ever owned that moves after the park brake is applied
