At 55 mph the front left brake engages without applying the brake pedal and after a few seconds releases, the bas and ESC faults are then visible on the dash. The brake light switch was replaced by Mercedes two times, but this condition shows up after a few days of driving, codes show that the yaw rate sensor or connection is at fault. Even when the car is in park with the engine running on a flat level surface the fault warning dash lights ESC and bas will come on with no movement in the car. This is a very dangerous situation for a collision from a vehicle following me and running into me. Many others posted the same problem. Why is there no recall ? I have 8 grandchildren that you should care about.

While driving on a level and straight road the car automatically applied brakes and came to a complete halt. Weather conditions where; clear visibility, about 85 deg F, dry asphalt surface. Error codes resulting from this fault indicates a faulty esp yaw rate sensor. The independent mechanic code reader showed that the yaw rate sensor output was reading angle rates from as low as 34 to as high as 300+ gradients/sec, while the car was not moving and parked at the shop. As the person responsible for any actions while driving this car, I that the car should not overrule the driver's inputs and create an unsafe condition. The vehicle should just indicate to the driver the existence of an unsafe condition and do not take any action until the driver acknowledges this warning/caution.
