Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

TAKATA RECALL I BOUGHT MY VEHICLE FROM MERCEDES BENZ OF LONG BEACH ON JULY 10, 2017. WHEN I PURCHASED THE VEHICLE THEY DID NOT INFORM ME OF ANY RECALLS! I SEARCH MY VIN TODAY 1/05/2019 THRU THE WEBSITE AND I FIND OUT THERE IS 2 RECALLS FROM 2016 AND IT SAYS THERE ARE NO REMEDIES YET AVAILABLE AND THE PROBLEM WAS ESTABLISHED SINCE 2016! I TAKE THIS RECALL SERIOUSLY AS IT SAYS THE AIRBAG MAY EXPLODE AND SHARP PIECES OR SHRAPNEL MAY HIT THE DRIVER CAUSING SERIOUS INJURY OR DEATH. I WAS DRIVING THE VEHICLE EVERYDAY TO WORK,TO DO ERRANDS, AND TO SCHOOL BUT NOW SINCE FINDING OUT THAT THE AIRBAG CAN KILL YOU INSTEAD OF SAVING YOU I WILL STOP DRIVING THE CAR UNTIL THERE IS A SOLUTION. I REALLY FEEL DECEIVED FROM MERCEDES BENZ OF LONG BEACH FOR NOT TELLING ME THAT THERE IS A VERY SERIOUS RECALL REGARDING THE AIRBAGS EQUIPPED ON THE VEHICLE I PURCHASED FROM THEM. IF THERE IS YET TO BE A REMEDY FOR THIS PROBLEM I FEEL AS IF MERCEDES BENZ OF LONG BEACH SHOULD PROVIDE A LOANER VEHICLE UNTIL THERE IS A SOLUTION TO THIS PROBLEM. I KNOW THAT IF I CONTINUE TO DRIVE THE VEHICLE AS IS AND I HAPPEN TO GET INTO AN ACCIDENT IT WILL NOT BE A GOOD SITUATION ON BOTH ENDS.

The tail lamps of my car do not function appropriately - the right tail lamp is completely dead most of the time and the left tail lamp constantly dims and flickers. Mercedes previously issued a recall campaign (no. 2014050001) because "DAG determined that oxidation on the ground pin connector for the rear tail lamps of subject vehicles can result in a dimming of the tail lights or loss of tail lamp functions. . . . [t]he loss of a rear tail lamp reduces the rearward visibility of subject vehicles . . . and may increase the likelihood of a rear end crash." The recall has been performed on my car, but the issues and danger continue to persist. I visually inspected the pin connectors of the tail lamps, confirmed that they still suffer from oxidization (and that they may have slightly burned due to the oxidization), causing the same continuing issues that were at the heart of the prior recall campaign. I reached out to Mercedes' corporate customer service, explained to them in writing that the same issues continue to exist (oxidization of the pin connectors which continue to cause tail lamp malfunction), showed them photos of clear oxidization of the pin connectors, and pleaded with them regarding the continued danger that is caused by the malfunctioning tail lamps. Despite the continuing clear defects and obvious dangerous conditions, Mercedes has refused to provide any assistance to repair the tail lamps. This is a serious design defect, and a quick google search confirms that it continues to be a widespread problem. At minimum, Mercedes should be pressed by the NHTSA to repair my tail lamps, free of cost. However, given that it appears that it continues to be a widespread problem that could potentially affect thousands of cars that continue to be road worthy, the NHTSA should investigate the extent to which Mercedes should be pressed to issue a second wider recall, because the first recall has not resolved the defects and dangerous conditions.

FUEL PUMP HOUSING CRACKED AND WAS LEAKING FUEL. THIS IS A PLASTIC PART. THE FUEL PUMP IS LOCATED UNDER THE REAR SEAT, SO THERE WAS FUEL INSIDE THE CAR. I NOTICED A STRONG GAS ODOR AND UPON INSPECTION, FOUND THE FAILED PUMP WITH GAS LEAKING FROM IT.
