One problem related to wiper has been reported for the 2007 Mercedes Benz ML350. The most recently reported issues are listed below.
While driving my turn signals, brake lights, windshield wipers, seat controls, and I'm not sure what else became inoperable. Also the srs warning displayed meaning the airbags were malfunctioning. Seems that the sam module is the culprit but nothing should be able to stop such vital safety issues from happening all at once. I have seen several articles about this happening and a recall is needed in my opinion.
