On our 2016 Superb it's being replaced for the 2nd time.
This is an installation problem as the driver side was done for the 2nd time by a high quality panel beater repair shop and has never moved again. While the 1st time was done by the dealer ship. Unfortunate for warranty reasons, the dealer ship has to do the work on the passenger side (both front and back). They just ordered the chrome strips and we had to point out that the rubbers need replacing as well, due to them being the real problem. It's the rubbers that creep past the vertical door edge if not installed properly.
I put my money on it that I will have to replace them again in a year or so as the dealers aren't experts in chassis/trim work.
So far the car has been brilliant and a 100% reliable mechanical wise with very few little niggle problems Skoda's support of their product has been outstanding so far.
More then good enough for me to consider a Kodiaq RS as a 2nd car in a couple of years.
