When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2013 Mercedes Benz ML350
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2012-2014 ML550, 2012-2015 ML350, AMG ML63, 2015 ML250, ML400, 2016 GLE450, GLE300, 2016-2018 GLE350, GLE550, 2016-2019 GLE400, 2017-2019 AMG GLE43, and 2016-2020 AMG GLE63 vehicles. Water might accumulate in the spare tire wheel well and damage the fuel pump control unit, which could cause an engine stall while driving.
Risk: An engine stall while driving increases the risk of a crash.

COMMUNICATION
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2013-2017 vehicles due to a software fault that may cause the date and time for the emergency call system (eCall) to differ from the actual date and time, potentially relaying an inaccurate vehicle location. For a full list of the affected models visit: https://static.nhtsa.gov/odi/rcl/2019/RMISC-19V787-4620.pdf

EQUIPMENT
Mercedes-Benz is recalling certain accessory all-season floor mats sold for use in model year 2012 and 2013 Mercedes-Benz ML-Class vehicles. This all-season floor mat may not fully conform to the contour of the vehicle's floor plan as intended. Clearance between the mat and the gas pedal may be reduced, possibly allowing the pedal to become trapped.
Risk: This interference could prevent the gas pedal from retracting and the vehicle may not decelerate as expected when the driver lifts their foot from the gas pedal, which could increase the risk of a crash. Should the pedal become trapped, steady application of the brakes will allow the vehicle to be brought to a stop.
Reports where the owner recorded a crash, a fire, an injury or a death.

ENGINE
The engine locked up after blowing the top part of the engine off, fire shot out of the engine and quickly went out like a flam thrower. I was driving on the expressway when the accelerator would not work without any warning I didn’t have any issues with this truck. The car cut off immediately thank God I was able to coast to the side of the expressway because it stopped in the left lane on the expressway I was scared for our lives. The dealership has the truck and they said the engine is locked up. This morning s unacceptable for a car I’ve had for a year.

THE CAR THEN STARTED JOLTING BACK AND FORTH; I HIT MY HEAD ON THE STEERING WHEEL TWICE AND GOT ALMOST KNOCKED OUT. THE ENGINE STOPPED WHILE I WAS STILL RUNNING AT 70 MPH. MOST IF NOT ALL THE LIGHTS IN MY DASHBOARD CAME ON THEN I STARTED SLOWING DOWN. THE SEAT BELT NEVER TIGHTENED ON ME AS THE CAR WAS JOLTING. I KEPT THE CAR ROLLING AND GOT OUT OF A VERY DANGEROUS SITUATION. AS THE CAR CAME TO A HALT, A LOT OF ENGINE OIL LEAKED ON THE STREET, MAYBE ABOUT AQUART. I TOOK A PICTURE AS I JUST GOT OUT OF THE CAR. ALSO, AS THE TOWING TOOK THE CAR, THE TOWING BED GOT OVER A QUART OF ENGINE OIL THAT LEAKED FROM MY CAR. I TOWED THE CAR TO MERCEDEZ BENZ OF NOVI BUT THEY REFUSED TO TAKE IT. THEY ORDERED ME TO TOWED IT OUT AND TOW IT BACK TO THEM TWO WEEKS LATER. I TOWED IT TO MERCEDES BENZ OF BLOOMFIELD ON SEPTEMBER 6. I NOTIFIED MBUSA OF THIS INCIDENT ON SEPTEMBER 7 AND PROVIDED THEM ACCESS TO CHECK THE CAR BUT THEY SHOWED NO INTEREST WHATSOEVER IN LOOKING AT THE COMPLAINT AS THE VEHICLE HAS 92,273 MILES AND IS OUT OF WARRANTY. THEY INSTEAD OFFERED ME A $2,000 DISCOUNT ON A PURCHASE OF ANOTHER VEHICLE.

I COULD HAVE EASILY WENT UNCONSCIOUS FROM THE JOLTING AND HITTING MY HEAD ON THE STEERING WHEEL. I THINK THERE IS A MAJOR SAFETY ISSUE THAT REQUIRES AT A MINIMUM FOR THE MANUFACTURER TO LOOK AT LET ALONE ISSUE A RECALL FOR SAFETY REASONS ON THE ENGINE AND THE SEAT BELT.

NHTSA VEHICLE SAFETY COMPLAINT SUPPORTING STATEMENT Vehicle: 2013 Mercedes-Benz ML350 I am submitting this complaint regarding a continuing safety concern involving water intrusion and electronic system damage in my 2013 Mercedes-Benz ML350. My vehicle was subject to a Mercedes-Benz recall involving water intrusion and related components. Despite recall-related repairs being performed, moisture and water intrusion concerns remain unresolved. During the diagnostic process, Mercedes-Benz personnel identified evidence of water and humidity in areas associated with vehicle electronics and control modules. The vehicle has experienced repeated mechanical and electronic issues following discovery of the water intrusion condition. Multiple repair facilities have been involved, and I have incurred significant diagnostic and repair expenses while attempting to determine the full extent of the damage. The primary concern is not ordinary wear and tear. The concern is that water intrusion has affected vehicle systems and that the recall remedy has not resulted in a complete resolution of the condition. I am concerned that moisture exposure may continue to impact vehicle electronics, control modules, sensors, and other safety-related systems. Mercedes-Benz USA has been notified and a case has been opened. The dealership has also been involved. However, despite escalation requests and requests for management review, I have not received a meaningful resolution. The dealership continues directing me back to Mercedes-Benz USA while Mercedes-Benz USA has not provided a final management response. I respectfully request that NHTSA review whether the recall remedy adequately addressed the water intrusion condition and whether additional investigation is warranted regarding continuing moisture intrusion, electronic system exposure, and potential safety risks associated with this condition. I am prepared to provide repair orders, recall documentation, photographs, diagnostic findin

FUEL/PROPULSION SYSTEM
Re: My 2013 ML350- Intermittent Start/ Vehicle cutting off while in heavy traffic. Fuel Pump and Fuel modulator failed due to water collecting in the spare tire wheel-weld causing water intrusion into the fuel system. I paid out of pocket for this service twice, AND then found out from MB Tacoma there was a RECALL with the exact same issue. I took the vehicle in to the closest dealer- Seattle Mercedes to handle the outstanding recall issues. I was advised to contact MERCEDES BENZ USA GOODWILL DEPARTMENT. My initial claim was approved, as I submitted ALL DOCUMENTATION of the repairs related to this issue. NOW, after 5 months of my RECALL REIMBURSEMENT CLAIM BEING BOUNCED AROUND by customer service agents that were not trained to handle recall issues- my dealership needed approval to process it. I even provided MB-USA w/a Bulletin # (FROM MB-USA) that clearly states to claim reimbursement IF THESE PARTS FAILED AND THE CUSTOMER PAID OUT OF POCKET.

Good morning ! I am an owner of a 2013 ML 350 . I live in San Diego ,CA ,92103 . I was driving my car on [XXX] and it was raining a lot . After around 30 miles I got to my destination parking area and my car died 20 feet away from the parking zone .I tried to reignite it but it wouldn’t start . I checked it with a OBD2 scanner and it was indicating a code U0109 - Lost communication with fuel pump control module . After looking into solutions and reasons for the issue online I came across a post regarding an existing recall with NHTSA with ID 22v955 regarding water intrusion in the spare wheel well portion of the trunk( The Wheel well is not water proofed and doesn’t have a drain port for water to escape ) . I proceeded with inspecting the area and of course it was full of water . The fuel pump control module is located in that area and it was damaged which shorted it and cause the malfunction of the vechile and the error code U0109 stated above . Tried calling Mercedes Benz but they confirmed about that specific recall but said my VIN is not part of it and I should file a claim or complain with you . I will attach proof and pictures of the water and the damaged component. My car now need to be towed and fixed on my expense because of Mercedes Benz negligence… Hopefully you can add my car to this recall and when this happens I would get some kind of reimbursement… Thank you for your time and understanding.

Brake Booster failure, this vehicle is exhibiting the EXACT same symptoms as described in Recall Campaign: Campaign No. 2024050001, May 2024 TO: ALL MERCEDES-BENZ CENTERS SUBJECT: Model GL-Class, ML-Class, and R-Class (X164, W164 and 251 platform) Model Year 2006 – 2012 Inspect Brake Booster – without Pedal Rework Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2006-2012 ML-Class, GL-Class, and R-Class (164 and 251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. Loss of braking power puts me and everyone I am near while operating this vehicle in eminent danger!! This problem has been inspected and documented by Mercedes Benz of Macon Ga. 9-3-25 There were no warning lamps or messages present.

Fuel system failed carbon and shut off without any notification while driving two times put me at risk of getting hit both times as the vehicle was not in a safe spot. This has been confirmed at the dealership where my vehicle is at this point. It has been inspected by the dealership in Georgetown, Texas. Again, no warning lights just cut off two times while driving. I already had one recall fixed two times dealing with the fuel system and now it’s shutting off with no notice while I’m driving 60 70 mph and causing a dangerous safety hazard. Dealer stated… pressure regulator and control valve field as it is designed to maintain and regulate the amount fuel flowing into the engine.

On [XXX], while driving on the highway about 30 miles from Columbus, Ohio my 2013 Mercedez Benz ML350 suddenly stalled and lost power. There was no prior warning. Luckily, we were in the outer lane with no car close behind us so my husband slowly guided the car to the side road. The car has since been towed and is currently at the Service Department at Mercedez Benz of North Olmsted, Ohio, 44070, for repairs. I have been informed by the Service Manager that they have identified the fuel pump to the problem and that it needs to be replaced. Coincidentally, this vehicle went for Maintenance Servicing at the same dealership and was returned to me on Monday December 16th. No problem with the fuel pump was identified or reported to me. This vehicle is available for inspection About 4 years ago, the exact same incident happened with this same vehicle where it suddenly stalled and completely lost power on the highway in the middle of nowhere on our way from Ohio to Iowa. There was no prior warning. Similarly, the car was towed to Mercedez Benz North Olmsted but per the same service manager their inspection revealed no problem and the car restarted on its own so nothing needed to be fixed. I am reporting this recurring problem with my vehicle because of the obvious safety risk of sudden stalling and power loss on the highway, the fact that 4 years ago when this happened Mercedez Benz should have recognized what the issue was and replaced the fuel pump but did nothing about it, and also due to the fact that many Mercedez Benz vehicles have experienced this same problem leading to multiple recalls including many 2013 ML 350s. I believe my vehicle has a defective fuel pump from the manufacturer just like the recalled vehicles and that my vehicle and many more need to be recalled INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM
Started to have an issue with the blind spot assist showing inoperable. Shortly after depending on the outside temperature the AC would start shutting off and on. The days the temperature was above 95 degrees the AC would suddenly stop working. Took the vehicle to the dealer for AC service. Dealer reports the engine "back" wiring harness had been rubbing, exposing and chaffing the harness wires, and for safety concerns a complete harness replacement is necessary. When asked how was this possible since the harness clearance is a manufacture design. Was told it happens on these vehicles and currently there is no recall.

LANE DEPARTURE: BLIND SPOT DETECTION
Both the front distronic system,which controls adaptive cruise control and emergency braking, and the blind spot warning have failed. Failure of both systems is usually caused by water getting into the respective control units related to poor sealing allowing water to enter and causing the systems to fail. I believe that these systems are critical to vehicle safety. The pre safe braking is essential to the safe operation of the vehicle. Blind spot warning failure is also a safety item on vehicles like these with large blind spot areas. Dealer has been no help other than repairs costing almost as much as the vehicle is worth. Very poor design and unsafe when these critical systems fail.
