Is the rear trunk supposed to always make the latching noise?

    Sometimes when the rear lift-gate closes, it just "thumps" and doesn't make the two-part gear latching noise. Is this normal?

    I've never, not noticed mine make the motor whine / latch noise after the thump. That doesn't mean it hasn't at some point; I just don't have any recollection of it not doing it.

    Don't know if it's "normal", but mine does the same thing.

    I'm probably wrong in this assumption but when it "thumps" I presume there is enough force when it closes to not make the latching noise.

    There is a cinch motor on the rear liftgate. When the liftgate closes, this is supposed to activate and pull the liftgate down. Sometimes I think the motors on the liftgate struts run a bit fast, such that the liftgate slams into the sill. The liftgate still seems to be tightly latched, and the car does not alert you for an open liftgate.

    FWIW on my 2013 my liftgate latching system seized with the liftgate barely open. Service had to replace the latch and cinch motor. I am hearing a few more S with this issue as the old builds age.

    Here is a video (turn your audio up). Please ignore my quick attempt at blurring out license plates :)

    It will do this more than half the times it closes. The other half, it will make the proper latching sound.

    It feels secure when it closes with the thump, and no alerts on screen. Just doesn't seem normal.

    The noise is the cinching actuator hooking the tailgate lid to the latch. It's always there. If you don't hear it it could be a problem.

    Any ideas about the video I posted? The trunk stays closed securely and I'm not seeing any alerts on the screen about it not being closed.

    It's very strange to hear it slam down, and then not cinch afterwards.
