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 Ben

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.

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

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.

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.

Power Steering Motor snapped from the casing while driving. Seems like a defective casting.
