Hi,
I have 2015 gla45 and sometimes right after you fully stopped it make low deep sounding knock, and it feels like you got tapped from behind very slightly.
After dropping car of at the dealer 2 times ,dealer said that is normal with sport transmition in 45amg we have.
the dealer communicated with Germany amg engineers about it, i called mb service directly, and they said yes its true, its shows in their date.
i think its total bull ****.
Any ideas?
also, when i put in reverse it make metal to metal shift sound. also they said its normal. wtf.

I just picked up a 2015 gla 45 amg- brand new...and had same experience!! I almost got out of the car and confronted this old guy whom I thought tapped me! It's defInanely more clingy and noisy. But guess its not normal.
