In mid-trip as we were going down the highway went to change lanes and the turn signals were no longer functioning. No errors, no alerts, no warnings they just stopped working. After pulling over and turning off the vehicle and turning back on they work for a time then stop working again. After researching with other owners of these and similar model Mercedes Benz vehicles this is a prevalent and highly dangerous safety issue that many many others have experienced.
