I am writing to inform you of a very troubling incident that occurred recently. I own a 2008 Mercedes benz cl550 with 31,000 miles on the odometer. On june 16, 2014, the seatbelt on my vehicle would not release from the seat, leaving me unable to buckle my seat. On top of the obvious safety hazard, illegality of driving without a seat belt, constant dinging from the vehicle to remind me that I was not buckled, which did not allow me to speak with my clients by phone in the vehicle, I had to deal with very poor handling of this matter by mbusa. I immediately brought the car into fletcher jones Mercedes benz in newport beach and had my service advisor take the car in to check out the seat belt malfunction and called me to tell me it needed to be replaced and that Mercedes benz usa (mbu

Ref: complaint 10549686 I am entering a second complaint regarding casting defects in order to simplify it and to present information that proves Mercedes-benz must replace one wheel on my vehicle. According to the usa consumer action handbook contacting NHTSA is suggested. The handbook made on thing clear, ?if a safety-related defect exists, the maker must fix it at no cost to you ? Even if your warranty has expired. P.10? I now know that two of the wheels have the defect, but only one is cracked. The crack runs down the middle of the defect. It initiated at the location of the defect and continues to grow by means of fatigue (repetitive loading and unloading). The are no indications that an impact initiated the crack. To be fair, I am only asking Mercedes-benz replace the uns

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 mi
