NHTSA complaint 11390663I WAS DRIVING ON THE FREEWAY AND MY WINDSHIELD EXPLODED.
NHTSA complaint 11322877MERCEDES BENZ HAS GROSSLY MIS-REPRESENTED THE ACTIVE BRAKE SYSTEM FEATURE. THE OWNERS MANUAL LEAVES OUT A KEY ELEMENT, WHICH IS THAT THE DRIVERS FOOT NEEDS TO BE OFF THE PEDAL FOR THE FEATURE TO ACTIVATE. I.E. THE FEATURE WILL ONLY WORK WHEN THE DRIVER IS NOT PRESSING THE ACCELERATOR. THIS IS A CRITICAL FEATURE AND ONE THEY SHOULDN'T OMIT. I EXPECT THE THE AUTO BRAKE TO COME INTO EFFECT WHEN I'M APPROACHING A CAR IN FRONT OF ME AT A A PACE THAT WILL LEAD TO A COLLISION. BUT IT DOESN'T WORK THAT WAY. FOLLOWING IS WHAT THE OWNERS MANUAL SAYS (NOTE THAT IT DOESN'T SAY ANYTHING ABOUT THE FOOT OFF THE ACCELERATION). "ACTIVE BRAKE ASSIST CAN HELP YOU TO MINIMIZE THE RISK OF A COLLISION WITH THE VEHICLE TRAVELING IN FRONT OR REDUCE THE EFFECTS OF SUCH A COLLISION. IF ACTIVE BRAKE ASSIST DETECTS THAT THERE IS A RISK OF COLLISION, YOU WILL BE WARNED VISUALLY AND ACOUSTICALLY. IF YOU DO NOT REACT TO THE VISUAL AND AUDIBLE COLLISION WARNING, AUTONOMOUS BRAKING CAN BE INITIATED IN CRITICAL SITUATIONS. IF YOU APPLY THE BRAKE YOURSELF IN A CRITICAL SITUATION, ADAPTIVE BRAKE ASSIST SUPPORTS YOU WITH SITUATION DEPENDENT BRAKING ASSISTANCE"
