I currently have a 2025 GLA 250 loaner for a few days. While driving it sounds like the back hatch/window is locking/unlocking all the time. It doesnt just happen once, its a few times as im driving. I'm used to auto locks, the doors lock when starting to drive, but like I said it keeps making the sound. What is it?

Also is there a way to turn off the feature where the engine keeps shutting off when stopped? I dont like it, the engine shuts off while im still coming to a stop and its just weird. I think it makes the brakes feel, dangerous.

I looked and the operators manual is not in the glove box to check. I tried navigating thru the screens on the dash and the screen in the middle and cant seem to find any settings.

 

I paid attention this time and the locking sound seems to occur when i'm going around 20mph. I hear it when im coming to a stop, and then when im taking off.
