Mercedes Benz ML320 owners have reported 2 problems related to brake warning switch (under the service brakes category). The most recently reported issues are listed below.
My 200 Ml320 (with +75000 miles) has an intermittent bas/esp warning light come on for about 6 months now. The mechanic says its some yaw sensor that has failed and that it might pull to one side under braking. I have noticed that sometimes its is hard to brake at speeds above 60 mph, if I need to make a quick stop.
