| Description of the problem | My 2008 mercedes benz cl550 is having a problem with brake. There is a thug-thug sound when i press down on the brake pedal. It goes away ~2 seconds after the gear is put into parking or neutral position. Mercedes benz knows about the problem and they told me that there is another car, a s class, that is having a same problem. S class is 4 door version of cl class. Mb told me that they are working on a new part over 3 months ago and now they are telling me that they are working on a software to fix a pressure problem in a valve. I don't understand the details but it sure sounds like an engineering issue meaning a defect. Mb said the issue is limited to a very small number of vehicles but i am not sure if that is the case. Noise was not readily noticeable but got louder so people might not notice it until later. I am very concerned because my brake pedal also feels much softer and weaker (need to press down further). I had this problem for ~4 months. |
