One problem related to warnings has been reported for the 2016 BMW 535. The most recently reported issues are listed below.
The head unit or the car stopped working. As a result, rear view camera, all warning systems or the car including warnings for low tire pressure, warnings for distance from objects in front, side and rear all stopped working. This is a safety issue with all safety features of the car were disabled. This is the second time head unit has stopped working on the same car and the second time when the head unit needed a replacement. Seems like a systemic issue and should be investigated with Bmws.
