I have Distronic Plus and all the driver assistance features. Per the subject, my 2017 GLS 450 abruptly swerves out of its lane for no apparent reason and under different conditions. It happens infrequently but could conceivably cause an accident if I didn't catch it quickly enough. I always keep my hands on the wheel. No warning is displayed when this happens I was wondering if anyone else is experiencing a similar problem. Thanks
