door detent

What is your question?

E300 2017 sedan passenger and driver doors detent too weak, If door pushed open hard it springs back to close. Door detent not strong enough to keep the door in open position or in-between position without "springing" back unless the door is swing out slowly. If the car is parked on an incline, then it is worse. Dealer says that "spring" or detent "resistance" or "strength" is the correct factory design.

How long has your 2017 Mercedes-Benz E300 had this problem?

Since purchased a year ago.
