The breaks on these vehicles are extremely dangerous . Before I leased this vehicle test drove 3 vehicles. The salesman said the breaks will adjust as you drive. They have not. ITS all over the internet that this vehicle has very unresponsive breaks. It takes 75 precent of pressure pushing down on the break pad distance before the car breaks engage. I already almost had an accident as the distance it takes for the car to respond is a significant distance before the car comes to a full stop. I have brought back the car to my dealership three times expressing my displeasure and each time I m told there is nothing they can do unless a fix comes from the manufacture. They said I'm not the first to complain about these dangerous breaks. What will it take for Mercedes to address this issue before someone gets killed. I hope there is someone at the NHTSA that will take the initiative to contact Mercedes and get them to address this very unsafe defect on these model cars. I thank you in advance.
