My W205 Jerk after 15secs in N gear

[KrissLeeVector]

I just got a W205 2016 and I have noticed that most of the time when I stop the car at traffic light... i go from D to Neutral (my foot is on the brake) but after like 10-15secs the car jerk a little (like got car "kiss" from back)

These days it’s not correct proceedure to put the car in neutral whilst waiting at lights or similar. Your car even has a “hold” function so you can remove your foot from the brake if you want to. A little extra dab of the brake pedal while stopped will bring a “hold” icon on your instrument cluster. I suspect there is nothing wrong with your car.
