2021 RS AWD/3.0 - When I approach my SUV with the key-fob in my pocket I can hear what I can only describe as a servo motor starting. I lasts foe about 10/15 seconds. Anyone else experience this and if so, what do you think it is? Thanks!

Raffy,

Welcome to the forum.
I notice what sounds like some type of motor when I open a door. There are other clicking sounds I notice when shutting the vehicle off and wait a few seconds before exiting. It took a little getting used to. I assume these sounds are normal.

Might be the electronic steering or a fuel pump. I'm going with the fuel pump priming like you would a lawnmower if you've popped the hood and seen our engines you'd laugh a little at that assumption.

Fuel pumps don't prime just from locking & unlocking the doors. It only primes as you start. We also don't have electronic suspension.

It scared me when mine went out 3x before I got it fixed under recall. Imagine someone who doesn't react with calmness or going down a hill....
I've now heard a few stories like yours which is why the electric brakes are questionable to me. They might be efficient, but lack of a failsafe makes me nervous and when you couple that with an electric parking brake well you know where I'm going, lol.

It seems like more and more do these days, but I still like old school emergency/parking brakes since they can actually be used in an emergency.
