The chrome plating has started to peel on the seat release handle of my C207 E class 250 coupe 2015. Is this a known or common problem covered by warranty? The reason I ask is that I previously had a C207 2010 that had the same problem and MB replaced it without charge. Love the car for comfort, performance, economy, pano roof, etc., as can be seen in the fact I bought a second but surprised at MB quality control even after 5 years
