2015 Mercedes-Benz C 300 Electrical Problems

I was driving my car was sputtering or trying to shut off while I press the gas and I let go of the gas and it catches and stayed on. I took it to the dealership and they said they found nothing wrong. May 3rd around 12pm im driving on the freeway and as im getting on the express lane going 60 it dies and I couldn't move the steering wheel and I slammed into a guardrail. After doing research my car (vin [XXX] ) had multiple recals from the fuel pump and steering wheel and the dealership never fixed or checked any recalls before selling it to me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Power steering malfunction Car unable to drive I believe there is supposed to be a recall for this issue but not popping up when I put in VIN number Warning lamps come up. Sometimes every light on dashboard. Took it to Mercedes but it was when code was not popping up and they said I needed a new battery. Did that but still an issue. Has also happened when driving. Sometimes collision assist plus light comes on and power steering acts up. Light I am pointing at in picture is another light that consistently pops up I have been able to intermittently fix problem by resetting computer by unplugging battery for 15min or longer. As well as confirming full service on vehicle. Now it isn’t working though.

Have noticed a lot of air noise coming from the panoramic sunroof of my vehicle when driving, and now have issues of it opening or closing properly. I researched and found a recall regarding the issues my vehicle is having, and brought it into a dealership for diagnosis. Was told my vehicle VIN was not included in the recall. This is a dangerous issue that needs to be remedied. If the sunroof malfunctions I’m afraid it will come loose from the vehicle as it is doing the same things that the recalled VIN vehicles had issue with. Mercedes needs to update and add additional VINs to this recall. I did not repair, as I was told the entire thing will need to be replaced.

The contact owns a 2015 Mercedes-Benz C300. The contact stated that while idling at a stop light, the STOP/START system activated; however, after releasing the brake pedal and attempting to accelerate, the instrument panel illuminated simultaneously with several unknown warning lights. The vehicle then powered off completely. The contact manually restarted the vehicle and the vehicle responded as needed. The contact turned off the Automatic STOP/START system. The failure occurred two additional times. The failure had not recurred with the Automatic STOP/START system deactivated. The vehicle was taken to the dealer but had not been diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 158,000.

When driving I accelerated and then the engine light turned on. after that the car was jolty and turned off completely when stopped. had to force a restart at the light. code that came back was p052E. This is a major and common issue with these cars. part is 400+ dollars. labor is much more since this is a 6 hour job. the work to replace this part is incredibly intensive that makes it impossible for regular car owners to change. Mercedes refuses to recognizes this as a common issue. but the truth is they designed a faulty system that they claim to have updated a handful of times now.

The dealership garage isla verde in carolina, refuse to service my car. They are the only Mercedes-Benz dealer in Puerto Rico and there is no other dealer that can service the recalls of my car. Currently they don’t want to fix the recall NTHSA# #21V197 Bonding of Panoramic Sunroof Panel - Wave 2 MY. Their service is poor and negligent. They make an appoinment to then cancel it and deny receiving me or my car on the only authorized dealer to fix the recall and denying any services to my car. They refuses my entrance.

Car was parked in Garage with garage door open. Wife and I wanted to go biking and the bikes needed air in the tires. Pre-positioned one bike directly behind parked car and one parallel with the pneumatic air pump prepositioned to inflate the tires. Went to driver's side door and started car with foot on the brake and pushed the button. I then plugged in the adapter for the air pump into the cigarette lighter. The whole time the driver's side door was open and the car was not moving. I exited the car and walked backwards and knelt down abeam the left rear automobile tire to inflate the bike tire. I started the pump at the unit and started to connect the hose to the bike tire, I was then hit from behind by the car door which bent backwards as it passed over me in reverse at low speed. The bike may have saved me by creating a wedge to bend the door back and away from me. The car started down my driveway and dragged the bike parked behind it underneath wedged and sparking across the ground. I got some scrapes but jumped after the car and tried to stop it by trying to slow it with my weight and strength and it was not stopping or slowing. I was worried I may get run over a second time and let it continue to roll at low idle speed across the street and into the neighbor's car that was parked. I am positive the car was not moving after I started it and I didn't have my foot on the brake to engage the reverse function one I exited the vehicle. I believe that the car engaged in reverse once I started the air pump. Maybe it was a voltage or electrical spike. I have used this pump setup many times before to inflate the car's tires and my bike tires but never saw it do this before.

WHEN ACCELERATING WITH MY MERCEDES C300, THE CAR IS ACTUALLY LOOSING POWER. THE EFFECT IS REINFORCED AS THE CONTROLLING SYSTEM IS BLOCKING THE ACCELERATION. RESULT IS THAT THE CAR IS BRAKING SUDDENLY INSTEAD OF ACCELERATING. IT IS PARTICULARLY DANGEROUS WHEN TRYING TO PASS ANOTHER CAR ON THE HIGH WAY AS THE CAR WILL BRAKE. I ALMOST EXPERIENCED TWICE AN ACCIDENT ON THE HIGHWAY DUE TO THIS ACCELERATION/BAKE ISSUE. I BROUGHT MY CAR TO AN INDEPENDENT MERCEDES REPAIR CENTER. THEY CONFIRMED TO ME THAT MERCEDES ISSUED A TECHNICAL BULLETIN FOR AN ELECTRICAL CABLE REPLACEMENT DUE TO THAT FAILURE. THE ISSUE DESCRIBED ON THE TB IS IDENTICAL TO THE EXPERIENCE ISSUE. I CONTACTED MY MERCEDES DEALERSHIP SERVICE DEPARTMENT. THEY INFORMED ME THERE IS NO RECALL AND DON'T CONSIDER THIS ISSUE A SAFETY ISSUE. THEY WON'T REPLACE THE ELECTRICAL CABLE UNLESS I PAID FOR THE "SERVICE". THE CABLE HAS NOT BEEN DAMAGED OR DISCONNECTED. IT IS SIMPLY FAULTY AND MERCEDES KNOWS THE ISSUE AS THEY ISSUED A TB FOR THE VEHICLE.

THERE IS A SERIOUS PROBLEM WITH THE VEHICLE MENTIONED ABOVE. THE ENTERTAINMENT SYSTEM AND THE REAR CAMERA DO NOT WORK. THIS IS A SERIOUS SAFETY CONCERN REGARDING THE REAR CAMERA. THE C-CLASS IS DESIGNED IN SUCH WAY THAT YOU DEPEND ON THE CAMERA WHEN REVERSING AND IT IS VERY DIFFICULT TO SEE THE REAR VIEW WHEN BACKING AND LOOKING FROM ALL ANGLES. I CALLED YOUR HQ IN MARYLAND FOR ASSISTANCE, THEY WERE UNAWARE OF POTENTIAL REPORTED PROBLEMS. THEIR BEST ANSWER WAS TO CALL THE DEALERSHIP. THE FOLLOWING DAY, I RECEIVED A PHONE CALL FROM NEW COUNTRY MOTOR CARS MERCEDES BENZ OF HARTFORD, CT STATING THAT THEY HAVE NOT HEARD OF THIS PROBLEM AND ITS VERY UNLIKELY THAT IT WAS ASSOCIATED WITH THE RECENT RECALL REGARDING THIS VEHICLE. UPON ARRIVAL, AND RETELLING MY STORY TO THE SERVICE ADVISOR HELDER CRESPO, HE TOLD ME THAT THEIR RECEIVED NUMEROUS COMPLAINTS ABOUT THIS PARTICULAR VEHICLE MAKE AND THAT OTHER CUSTOMERS ARE AFFECTED BY THIS SIMILAR PROBLEM. IT BEEN THREE WEEKS, I HAVE NOT HEARD ANYTHING FROM MB OR DEALERSHIP. I AM QUIET APPALLED BY THIS MATTER AND SHOCKED BY THE IMPROPER COMMUNICATION FROM MB TO THEIR LOYAL CUSTOMERS. IS THIS 'THE BEST OF NOTHING' CUSTOMER RELATION?! I AM EXTREMELY DISSATISFIED HOW THIS MATTER IS BEING HANDLED AND THAT NOT EVEN ONE SINGLE PERSON WHO KNEW ABOUT THIS ISSUE DID NOT EVEN APOLOGIZE FOR THE INCONVENIENCES THAT THIS HAD CASED ME.
