2015 Mercedes-Benz ML-Class Complaint Log

The failed/malfunctioning component appears to be the fuel pump controller / fuel pump control unit, and possibly the fuel pump system. The Mercedes-Benz dealer identified water/moisture-related damage and corrosion at the fuel pump controller area. The failed component should be available for inspection if the dealer preserves the part during repair. I have requested that the dealer not discard the damaged component. My safety and the safety of others were put at risk because the fuel pump controller is related to fuel delivery. If it fails, the vehicle may not start, may lose fuel supply, or may stall while driving. This creates a safety risk, especially if the vehicle stalls in traffic, at an intersection, on a highway, or during normal driving. The problem has been confirmed by a Mercedes-Benz dealership. The dealership diagnosed water/moisture damage to the fuel pump controller area and provided an estimate of $768.22 for fuel pump controller replacement, plus $244.88 for the inspection fee. The dealer also indicated that this was the first inspection and that the fuel pump itself may also need further inspection or may have related damage. The vehicle/component has been inspected by a Mercedes-Benz dealership. Mercedes-Benz USA / the manufacturer’s representative has also reviewed the case through its goodwill process, but they refused to treat it as recall-related coverage. To my knowledge, the vehicle has not been inspected by police or insurance representatives. Prior to the current failure, the vehicle had starting/no-start related symptoms beginning around the middle of 2023. The engine could not start successfully at times. I do not recall receiving a clear warning lamp or message specifically identifying the fuel pump controller before the failure. However, the symptoms were consistent with a fuel delivery problem, and the dealer later confirmed water/moisture corrosion damage in the fuel pump controller area.

In July 2025, the sunroof panel had lifes and was flapping at highway speeds. I immediately contacted a Mercedes-Benz dealer to report the hazard. I was told they were unaware of such an issue and that I would have to pay for the repair out-of-pocket. Due to financial hardship, I could not afford the repair at that time. in. In early February, while driving on the highway, the entire sunroof panel catastrophically detached and flew off the vehicle. This created an immediate and severe road hazard for other drivers. This incident matches the 'adhesive bonding failure' described in other Mercedes-Benz sunroof recalls (e.g., Recall 21V-197), but my specific VIN was not included in that list.

In mid-trip as we were going down the highway went to change lanes and the turn signals were no longer functioning. No errors, no alerts, no warnings they just stopped working. After pulling over and turning off the vehicle and turning back on they work for a time then stop working again. After researching with other owners of these and similar model Mercedes Benz vehicles this is a prevalent and highly dangerous safety issue that many many others have experienced.

Rear subframe rusted from the inside out causing structural failure. This matches the defect in Campaign #2023020002 for other Mercedes models."

Cam Shaft replacement diagnosed after week and half visit to Mercedes Benz dealership for engine rattling at cold start up. We are left with a $10,000 repair after performing all scheduled maintenance at the Mercedes Benz dealership since owning in 2015.

The contact owns a 2015 Mercedes-Benz ML350. The contact stated that while driving at various speeds, the vehicle shook abnormally before the vehicle lost automotive power. The contact was able to restart the vehicle and take the vehicle to a local dealer. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 22V955000 (Fuel System, Diesel, Fuel System, Gasoline); however, the repair failed to prevent the failure. The contact stated that two weeks after the recall repair, the failure reoccurred. The check engine warning light was illuminated. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The vehicle was scanned by a local independent mechanic who retrieved DTC: P035413, A10D, P072102, U016886, V1FBD04, 94C3, V1DAV54, V1DBD31, P030085, and V142E31. The manufacturer was made aware of the failure. The failure mileage was approximately 88,000.

I was in drive mode and was looking to park the car on the open spot on the street. Had engaged the reverse gear and was attempting to get in the parallel parking spot. While i was doing that, suddenly the wheel locked up and car stopped with a jerk/jolt. Then came warning that the parking brake was not working (Remember I had not engaged the parking brake as I was in drive mode). The locked up wheel would not move and I had great difficulty in making the car safe in the cross traffic. The issue here is parking brake cannot engage by itself. That has nothing to do with the age of the car, it is like the wheel cannot come off just because the car is old. This could have easily happened while the car was in motion at a higher speed, in that case with 1 wheel locked, a car would spin out of control in a moving traffic causing major damage to other vehicles and myself. Mercedes's rep claimed it was a maintenance item. Parking brake engaging by itself is a maintenance item?? We should put a notice to all customers and your life is in danger because the parking brake can engage by itself locking the wheel anywhere anytime. I am very apprehensive of this design which allows for auto lock of a wheel. It must be investigated and all the parking brake systems should be replaced as it can happen to anyone. Thank you

In April 2023, while performing a rear brake service both right and left suspension springs were found with deteriorated suspension spring coating, corrosion and breakage of the coil springs.

The date of incident is the date I discovered the spring breaks. I only took a pic of the one spring but both were confirmed broken. MB dealership confirmed breakage.

Neither back doors on my 2015 ML350 lock. Even after you try to lock them from the inside anyone can open the doors from the outside. This is a huge safety hazard because someone could easily car jack the car while you are in it. I bought the car new from the local dealer and i have reported this to the dealership and they said it was a known problem and that acutuators on both doors needed to be replaced at a large cost to me. I wrote to Mercedes Corporate to report this and to ask for financial assistance in trying to get it corrected and was told to just report it to you. Thank you for any assistance that you can provide.

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ ML250. THE CONTACT STATED THAT THE COLLISION PREVENTION ASSISTANCE FEATURE FAILED TO FUNCTION PROPERLY AND THE VEHICLE FAILED TO STOP SEVERAL TIMES. THE CONTACT APPLIED EXTREME FORCE TO THE BRAKE PEDAL AND ALMOST EXPERIENCED A CRASH DUE TO AN INTERNAL OR ELECTRICAL FAILURE. THE DEALER (MERCEDES-BENZ OF ANAHEIM, 5395 E LA PALMA AVE, ANAHEIM HILLS, CA 92807, (714) 777-1900), WHO SOLD THE CONTACT THE VEHICLE, WAS UNABLE TO REPLICATE AND DIAGNOSE THE FAILURE. THE DEALER DID NOT PERFORM A TEST DRIVE AND INDICATED THAT THE FEATURE COULD NOT BE REPLICATED. THE MANUFACTURER WAS NOTIFIED OF THE SAFETY CONCERN AND THE CONTACT WAS WAITING TO DETERMINE IF THEY COULD PROVIDE FURTHER TESTING TO DETERMINE IF THE COLLISION PREVENTION ASSISTANCE FEATURE WAS FUNCTIONING. THE CONTACT WAS UNCERTAIN IF THE MANUFACTURER COULD PREVENT THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 20,000.

THE VEHICLE WAS IN REVERSE WHEN A STRONG SOUND WAS HEARD COMING FROM THE BACK, AFTER STARTING THE CAR, IT DISPLAYS A WARNING MESSAGE LIGHT ON THE DASH; IT BECAME DIFFICULT TO MANEUVER AND A SQUEALING SOUND WAS HEARD COMING FROM THE ENGINE, THIS COULD EASILY HAVE RESULTED IN A LOSS OF CONTROL AND A CRASH WITHOUT ANY WARNING. IMMEDIATELY MBRACE WAS CONTACTED AND THE VEHICLE WAS TOWED AND TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE POWER STEERING CONTROL FAILED AND NEEDED TO BE REPLACED WITHOUT WARRANTY AND AT MY OWN COST. THEY ACCUSED ME THAT THE CAR MUST BE INVOLVED IN AN INCIDENT/ACCIDENT, BUT IT IS TOTALLY IMPOSSIBLE FOR THE CAR TO HAVE SUFFERED A HEAVY BLOW, OR TO HAVE GONE INTO A HOLE, OR TO CLIMB A HIGH SIDEWALK, ETC. WITHOUT A SIGN OF DAMAGE; THE DAMAGE PIECE (STEERING GEAR) IS LOCATED IN A PLACE THAT WOULD BE TOTALLY IMPOSSIBLE TO REACH WITHOUT THE CAR SUFFERING A HEAVY IMPACT, WHICH WOULD HAVE CAUSED AN ADDITIONAL EXTERNAL DAMAGE BELOW, OR IN THE TIRE, BUMPER, RIM, OR ANY OTHER PART, EVEN THE AIR BAGS. THE CAR EXTERNALLY INCLUDING EACH SINGLE PART, IS IN PERFECT CONDITION. THIS DAMAGE WAS NOT CAUSED BY ANYTHING THAT I DID WRONG; MUST BE A DEFECTIVE PART FROM THE MANUFACTURE, AND I CAN'T NOT ASSUME RESPONSIBILITY OF THIS. THE MB USA WAS MADE AWARE OF THE FAILURE, AND THEY INSIST THAT I HAVE TO PAY FOR IT OR MY CAR INSURANCE NEEDS TO BE RESPONSIBLE MONETARILY OF THIS SITUATION, WHICH IS COMPLETELY UNFAIR TO ME AND SHOULD BE COVERED BY THE WARRANTY. IT HAS ONLY 18,000 MILES APPROX. AND I SHOULDN'T HAVE SUCH A SERIOUS PROBLEM WITH THIS BRAND AT SUCH LOW MILEAGE. IF A DEFECTIVE DRIVING PART IN THE STEERING GEAR EXISTS IN THE VEHICLE, THAT CAUSES IT TO BREAK DURING NORMAL VEHICLE TURNING, THE NORMALLY AVAILABLE HYDRAULIC SUPPORT FUNCTION WILL NO LONGER FUNCTION AND STEERING WHEEL OPERATION WILL BE LIMITED. *TR
