Just like the title says. About a month ago, the "next track" button on my steering wheel stopped working. A week later it worked intermittently, and for last three weeks not at all. This is a 2016 MCS with H/K and bluetooth. The dash next track button works fine. Car is still in warranty, but I dread the thought of dealer ripping apart dash and creating a creaky, rattly noise in car that is dead quiet, no wind noise, nothing ... except the streaming music from my iPhone 6 and the exhaust when I double-tap the blue tooth.
