I took my car in for a different repair and they found this issue as well. "Diagnostic - Oil leak (Visual): front covers leaking oil down front of engine." The leak was due to a crack in the sealing cap. My car 2015 Mercedes ML350 4Matic is in the recall for 2018070015 but my VIN number was not included in the recall although I am having the exact issues the recall covers. Recall 2018070015 "correct oil level as necessary and replace the reservoir sealing cap to prevent oil foam from leaking out."

The center console box will jot close. I have researched and this is a common problem with this car. You can not just replace the closure part it requires a whole new box. This is at a cost of 400.00plus dollars. This is obviously a defect.

SUSPENSION
3 complaints
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. Suspension spring failure poses a safety hazard and risk of damage to other suspension components. It is unclear when exactly the springs broke but when the vehicle was inspected in Feb of 2022 there was no mention of spring breakage. 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. Communication with Mercedes Benz was not successful.

Steering wheel tilt adjustment failed. Without adjustment it is impossible to steer the automobile safely due to hand placement for control. This is apparent especially when there are multiple drivers. There is not a manual over ride since the system is controled electrically

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ ML250. THE CONTACT WAS TOWING AN UNKNOWN TRAVEL TRAILER WHEN THE VEHICLE BEGAN TO DRIFT TO THE RIGHT AND THE STEERING WHEEL BECAME DIFFICULT TO TURN. THE CONTACT STATED NO WARNING LIGHT WAS ILLUMINATED. THE CONTACT STATED HE WAS UNABLE TO CONTROL THE VEHICLE AND DROVE INTO A DITCH. THE CONTACT STATED ALL 4 AIR BAGS DEPLOYED.

Jul 20, 2020
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

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.

REAR TAILGATE WAS LEFT OPEN. STARTED CAR AND NO WARNING THAT TAILGATE WAS OPEN WAS GIVEN. STARTED TO MOVE CAR INTO GARAGE AND OPEN TAILGATE STRUCK GARAGE OPENING. DAMAGE IN EXCESS OF $1000. NO WARNING IS GIVEN UNTIL CAR EXCEEDS 6-7MPH!!! THIS IS A SAFETY ISSUE, AS SOMETHING IN THE BACK WOULD ALREADY HAVE FALLEN OUT BEFORE ANY WARNING.
Jan 03, 2016
I RECENTLY PURCHASED A NEW ML350 FROM MERCEDES BENZ OF BURLINGTON, MA AND I HAVE A 'SAFETY' RELATED ISSUE WITH THE LIFT GATE. I WENT TO MOVE THE VEHICLE, NOT KNOWING THAT THE LIFT GATE WAS OPEN.THERE WAS NO WARNING OR ANY INDICATION THAT THE LIFT GATE WAS OPEN!! I HAVE OWNED 2 ACURA MDX'S AND BOTH GAVE LOUD WARNINGS WHEN THE CAR IS PUT INTO DRIVE AND THE LIFT GATE IS OPEN. I BELIEVE THIS IS AN OBVIOUS SAFETY OVERSIGHT BY MERCEDES IN THEIR DESIGN AS THE TAILGATE WARNING DOES NOT COME ON UNTIL A CERTAIN SPEED IS REACHED. THE WARNING SHOULD BE EVIDENT THE MOMENT THE CAR IS PUT INTO DRIVE. I BELIEVE THIS IS A SERIOUS SAFETY DESIGN FLAW THAT COULD LEAD TO INJURIES IF SOMEONE, OR EVEN A DOG, WAS IN THE BACK AND THE CAR DROVE FORWARD WITH THE LIFT GATE OPEN. I JUST SPOKE WITH A MERCEDES CUSTOMER SERVICE REPRESENTATIVE, AND SHE INDICATED THAT THIS IS A 'SPEED SENSITIVE' FUNCTION AND 'YES' YOU COULD BE DRIVING WITH THE LIFT GATE OPEN UP TILL THAT SPEED IS REACHED AND YOU WOULD NOT RECEIVE ANY WARNING AT ALL. IF I HAD PUT MY DOG OR ANYTHING IN THAT CARGO AREA AND STARTED TO DRIVE AWAY, THE WARNING WOULD COME ON TOO LATE TO PREVENT WHATEVER WAS BACK THERE FROM 'FALLING OUT'. THAT'S A SAFETY FLAW WITH A POTENTIAL OF INJURIES. MY OTHER CARS, INFINITI AND ACURA BOTH GIVE WARNINGS WHEN ANY DOOR OR LIFT GATE IS OPEN. PLEASE NOTIFY MERCEDES TO FIX THIS OBVIOUS SAFETY FLAW THAT ALL OTHER MANUFACTURERS HAVE SEEM TO HAVE FIXED. THANK YOU *TR

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

WHEN AT A SLIGHT INCLINE OR DECLINE, THE VEHICLE WILL GO FROM THE "DRIVE" GEAR AUTOMATICALLY INTO "PARK." WHEN THE "DRIVE" GEAR IS RE-ENGAGED, THERE IS A SIGNIFICANT CRUNCHING OF THE GEARS AS IT GOES FROM "PARK" BACK INTO "DRIVE" MODE, CAUSING UNDUE STRESS AND FATIGUE ON THE BRAKING MECHANISM, INCREASING THE LIKELIHOOD OF BRAKE MALFUNCTION AND/OR FAILURE.

There is a recall for this significant safety risk. I contacted my local Mercedes Benz about recall remedy on 6 January 2023 and they confirmed the recall and said MB would issue steps to get this taken care of in the beginning of February. It is now 18 February 2023 and this has not happened and I have received no communication from MB and yet the safety risk still exists and could be life threatening.

IT HAPPENED SO FAST THAT I LOST CONTROL OF THE VEHICLE I COULD NOT STOP THE CAR THE BRAKES DID NOT WORK. AFTER I HIT THE WALL I WAS JOLTED FORWARD AND I SMASHED THE FRONT END OF THE CAR WITH THE GARAGE. THE CAR FINALLY STOPPED IN THE MIDDLE OF THE DRIVEWAY. AGAIN, I DID NOT PUT THE CAR IN DRIVE WHEN I WAS JOLTED FORWARD THE CAR WENT FORWARD FROM THE IMPACT OF THE HIT FROM THE WALL AND I DID NOT PUT MY FOOT ON THE ACCELERATOR.

THIS NEW MERCEDES-BENZ ML400 HAS A MANUAL TRANSMISSION FEATURE THAT WITHOUT REASON REVERTS BACK TO AUTOMATIC WITHIN ABOUT 10 SECONDS WITHOUT ANY REASON. THIS PREVENTS THE DRIVER FROM BEING ABLE TO CONTROL TRACTION IN SLIPPERY OR OTHER DIFFICULT CONDITIONS, WHICH CLEARLY WAS OUR EXPERIENCE. THIS FEATURE IS MISREPRESENTED IN THE OWNERS MANUAL WHICH STATES AS HAVING A MANUAL TRANSMISSON CONTROL CAPABILITY AND WAS ALSO SOLD AS SUCH BY THE DEALERSHIP.
