I purchased a new vehicle from the dealer in 2014 in 2019 the wood grain trim cracked. I had this replaced by the dealer in 2019. Now again, in 2024, the same issue the wood grain has cracked. This should not be happening every few years.

Vehicle failed oil consumption test. Vehicle has been leaking and/or losing oil for months despite the issue being alleged fixed under NHTSA recall 18V272. The issue is ongoing and Mercedes Jacksonville is claiming the oil leak is from another issue not covered under warranty or recall order. I do not believe they are unrelated and they have not been able to identify the exact issue.

The contact owns a 2014 Mercedes-Benz ML350. The contact stated that while at a stop light, the vehicle lost motive and electric power and stalled without warning. The contact restarted the vehicle, but the vehicle failed to remain running. The vehicle was towed to an independent mechanic and the contact was informed that water had intruded into the rear of the vehicle causing electrical failures. The vehicle was not repaired because the Insurance Company deemed the vehicle a total loss. The manufacturer was contacted but offered no assistance. The failure mileage was 60,000. The contact stated that the interior of the vehicle has to be dried out first in order to assess the damage to the electrical system. The contact noted the failure mileage was 60379.

Instrument Cluster malfunction. Battery drained and replaced. 2.5 weeks later, the new battery drained. After the vehicle was jumpstarted, the instrument cluster remained on with SOS inoperable showing on the panel. The instrument cluster will not turn off, even after the vehicle has been turned off. So it continues to drain the battery. Mercedes has diagnosed the vehicle with a bad instrument cluster and says that it needs to be replaced. There were no warning signs before the malfunction. I drove it and parked it. Then two days later the battery was dead. 10.19.21 - took vehicle to Mercedes for a regular schedule B service 10.21.21 - vehicle battery was dead after trying to crank it. 10.22.21 - Mercedes sent tow truck to bring it back to them. The battery was replaced on 10.25.21 and I picked up the vehicle. 11.10.21 - Vehicle NEW battery was dead again. Mercedes sent tow truck. The tow truck driver jumpstarted the vehicle and couldn't get the vehicle into neutral. Then the SOS inoperable message appeared. Vehicle was towed to Mercedes and diagnosed the next day (11.11.21) with a bad instrument cluster. Apparently there are no new instrument clusters available in the world, according to Mercedes, they are on backorder. And I cannot get a loaner vehicle. So they'd like for me to be without a vehicle for the foreseeable future.

Known defect with timing issues that give code P0016. All cars should be part of this recall regardless of mileage on a known defect. This repair is extremely expensive and wouldn’t be needed if built correctly.

As we were driving 50mph, the car stalled and lost all power. The dashboard lights all lit up and the car wouldn't start. I don't get unnerved easily and it was fairly intense not being able to move your car out of traffic. After about 5 mins, the car would start again only to stop a minute or so later. After taking the car to the dealer, the issue stemmed from the fuel pump electronics board getting wet in the spare tire wheel well where water was accumulating. This was part of the recall and the dealer installed a drain and replaced the board. HOWEVER, this issue again happened nearly one year later in our next rainy season. After taking it to the dealer, they said WE would need to replace the electronics board ourselves. We asked about the recall and they said they fixed the issue by installing the drain plug and there was nothing else they could do for us. Even the service adjuster was upset and very sympathetic to our plight as the car was obviously not fixed. Even though the drain plug was installed, the water was still acumulating in the wheel well. It seems apparent to me, and several others who have complained about the same issue, that the recall fix has not addressed the main issue of why the water is coming in and why it's still not draining. Unfortunately we're going to have to fork over 1200 to have it fixed. My ask to the NHTSA is that this issue be readdressed with Mercedes. I would like them to be notified that the recall does not address the underlying issues and the solution they provided does not fix the problem. I appreciate your time in considering this.

DIESEL FUEL LEAKS FROM A TINY CRACK FORMING ON THE OIL FILTER HOUSING. THE FILTER HAS MANUFACTURING OR DESIGN DEFECT THAT CAUSES THE BOTTOM HOUSING OF THE FILTER TO FORM SMALL CRACKS PREMATURELY. THE MERCEDES PART NUMBER OF THIS FILTER IS A 642 090 60 52 MANUFACTURED BY MANN , MADE IN THE CZECH REPUBLIC. I HAVE SEARCHED THE INTERNET AND THIS APPEARS TO BE A SYSTEMIC PROBLEM WHERE THE FILTER FORMS CRACKS AND LEAKS DIESEL FUEL. THERE SHOULD BE A RECALL ISSUED FOR THIS IMMEDIATELY BEFORE THERE ARE ANY VEHICLE FIRES AS A RESULT OF THIS DEFECT. WHEN THE FILTER LEAKS, THE FUEL STREAMS DOWN THE CENTER OF THE ENGINE BLOCK AND THROUGH A WEEP HOLE TO THE BOTTOM OF THE VEHICLE NEAR THE EXHAUST. THIS IS IN VERY CLOSE PROXIMITY TO THE EXTREMELY HOT EXHAUST PIPING THAT COULD IGNITE THE FUEL AND CAUSE A FUEL FIRE RESULTING IN SERIOUS INJURY OR FATALITIES.

Vehicle: 2014 Mercedes-Benz ML350 VIN: [XXX] I have experienced repeated failures of the Blind Spot Assist / driver-assist system since purchasing this vehicle. When I first purchased the ML350 in Texas, the vehicle already showed warning messages (“Blind Spot Assist Inoperative / Pre-Safe Function Limited”). The dealer attempted repairs before delivery, but the defect persisted. After moving to New York, the problem continued. On June 26, 2023, I took the vehicle to The Automaster Mercedes-Benz in Shelburne, VT. Their diagnosis confirmed water intrusion into the blind spot radar sensors, consistent with Mercedes-Benz TSB LI54.71-P-056477. Both left and right sensors and wiring require replacement. This is a safety defect because Blind Spot Assist and Pre-Safe features are disabled without warning, increasing risk of collision when changing lanes. Many other owners have reported the same issue, and Mercedes has issued a TSB acknowledging the defect, but no recall has been provided. I request that NHTSA investigate this recurring safety problem and require Mercedes-Benz to provide coverage or a recall for affected vehicles.

The contact owns a 2014 Mercedes-Benz ML350. The contact had received notification of NHTSA Campaign Number: 22V955000 (Fuel System, Diesel, Fuel System, Gasoline). The vehicle was taken to a dealer and the recall repair was performed. Soon after the recall repair, while the contact's wife was driving 25 MPH, the vehicle stalled. The contact was unaware if any warning lights had illuminated during the failure. The vehicle was towed to an independent mechanic where it was discovered that there was moisture in the spare tire wheel well. The moisture damaged the fuel pump control unit which was linked to the recall. The contact attempted to reach the manufacturer but was unsuccessful. The vehicle was taken back to the dealer but was not repaired and remained in dealer possession. The failure mileage was unknown.

I purchased my car used at the Mercedes dealership in Tyler Texas June 2023. I took all my savings and paid cash and was told that the car was impeccable shape and there were no current issues and all the service records were up to date. November 2023 is when everything started happening and my engine light came on. It was revealed to me by a service tech that I was sold the vehicle with an existing major oil leak /seals broke. Etc. SEE Attached invoices. I have endured driving down the road and my car just giving out and losing power steering. The car has been sputtering and there have been misfires, fauled fuel injectors, coils, s and spark plugs, oil leaks, fuel pump leaking gasoline in the engine and smoke coming from the hood. I thought my car was going to start on fire it smelled like a hot electrical wires and gasoline. My nerves are frayed from this car because of how many times it has broke down. I have missed work because of the car, I'm behind on my home bills, I missed my airline flight to see my sick father, I have had to pay for rental cars, all due to this vehicle. I am very concerned for my safety in this vehicle and I would like the vehicle fixed at the expense of Mercedes or my money back.

May 30, 2020
WHILE ENTERING THE HIGHWAY, THE VEHICLE SHIFTED AT EXTREMELY HIGH REVS, THEN BECAME 'STUCK' IN FOURTH GEAR. THE MANUAL SHIFTING PADDLES WOULD NOT SHIFT THE TRANSMISSION UP OR DOWN. PLACING THE VEHICLE IN NEUTRAL, AND THEN BACK INTO DRIVE HAD NO IMPACT. VEHICLE REMAINED IN FOURTH GEAR. BECAUSE I WAS ON A HIGHWAY, IN HIGH SPEED TRAFFIC, IT WAS A DANGEROUS SITUATION. EVENTUALLY, I WAS ABLE TO PULL OF THE HIGHWAY, TURNED OFF THE CAR AND ONCE IT WAS RESTARTED, THE CAR SHIFTED NORMALLY. THE HIGH-REV SHIFTING EVENT HAD OCCURRED ONE TIME BEFORE (APPROXIMATELY 3 MONTHS AGO), BUT BECAUSE OF THE SHORT NATURE OF THE TRIP, I NEVER REQUIRED SPEEDS ABOVE 35 MPH.

It seems that this vehicle was not included in a brake booster recall which included this model from 2005 through 2015. The brakes are not working properly, and brake fluid has entered the master brake cylinder damaging the seal. It is extremely unsafe to operate this vehicle in this condition. Somehow, this vehicle was not included in the recall, but definitely should have been.

I purchased a used Mercedes-Benz from Freehold Mitsubishi in early 2024. Within hours, serious safety issues appeared, including a check engine light, cylinder misfire, EVAP leak, traction control failure, and blind spot assist malfunction. The vehicle’s ECM and wiring harness were later found damaged due to oil leaks and electrical shorts. Despite multiple repair attempts, the vehicle was returned in worse condition and remains unsafe to drive. I am reporting these issues due to their potential risk to vehicle safety.

TIRES
1 complaint
I purchased four brand new "GoodYear" tires with this location in February 2024. Within two months of this purchase, I experienced two flat tires in which both times I had to pay $87 and some change. Addtionally, within a year, two of the tires became bald, indicating premature wear. Tragically, this month, the bald tires contributed to a car accident, resulting in damages of my vehicle and loss of time from work. This incident has caused significant distress and has raised serious concerns about the quality of the tires and the services provided from this location. I have attempted to resolve this matter directly with the service center and cooperate office. To this day, no adequate response has been addressed to resolve my concerns. I'm glad to live to be able to tell my story and advocate for others!!! Tire Size 255/50R19`

ML350 engine stalled while driving on an expressway and would not turn back on. ML350 needed to be towed where it was determined that water accumulated in the spare tire wheel well, leading to the fuel pump short circuiting. This is directly related to NHTSA campaign 22V955000. That recall repair was completed prior to this incident. Per the technician, the recall repair installed a water drain plug to prevent the water accumulation. This repair effectively failed - the drain plugs malfunctioned and were not allowing water to drain. MBUSA deny’s responsibility for the failing drain plug - stating that the trunk weatherstripping is the root cause, not the failing drain plug. This is an unacceptable response and worth of the recall being expanded. The fuel pump control unit can still short out if MBUSA’s poor excuse of a recall fix fails as it did with mine.

I bought my vehicle into Mercedes Benz for a recall related to water collection in spare tire well which can cause a fuel pump control malfunction, NHTSA recall # 22V955. A few days ago, my vehicle could not start and I found water in my spare tire well. My OBD scanner tells me it is related to the fuel pump. I informed Mercedes Benz and they would not fix it. Obviously the work performed did not correct the recall. I'm writing here hoping I can get connected to the right channel to get this resolved as my vehicle is currently unusable. Thanks.

I thought “what the heck?”as I didn’t have any marks on the seat!! Clearly the temperature spiked and causes the burns!’ I looked it up and see that MB has had a long history of this…and major litigation. But no recall!! I have pictures!! (But for obvious reasons can’t send here) I had a miserable ride home and the pain continues! It is embarrassing but I want to make sure other unsuspecting people don’t have this happen!

I am writing in regards to my 2014 ML 350 Suv. The check engine light came on and upon taking it to the mercedes dealership, I was told the issue is that the camshaft adjusters have failed and need to be replaced. The cost quoted is over $11,000 to repair. Upon further investigation I found reports on multiple lawsuits for the Mercedes C series for the same year (2012-2014) that resulted also in a recall whereby customers were given a recall to replace at no charge the camshaft adjusters up to 120k miles. My car only has 83k and I am told by two independent mechanics that the camshaft adjuster should not be failing like this and that this has been an ongoing issue with Mercedes. The safety issue is that I am told by independent mechanics that what could happen over time is that I could be driving and the entire engine/power just shuts off. This could even happen at high speeds on the highway. The mercedes dealer tells me there is no safety issues that could result from camshaft adjuster problems which doesn't appear to be true as per the other independent mechanics. I request further investigation into this issue because as per the independent mechanics its the "same engine" as the 2012-2014 that are under the recall . I'm requesting a recall on this for my car that Mercedes pays for. This should not be failing especially in a car with only 83k on it . If the C series 2012-2014 received recall on this part then I also think my ML 350 should be covered. Mercedes customer service tells me they cannot pay for the repair, they said I could file complaint for recall through NHTSA Thank you .

Power Sun ROOF is coming off the tracks of the roof which it is attach to. I feel this is an extreme safety hazard because I believe it will eventually come off my vehicle and cause a serious accident flying into another vehicle or even a pedestrian. This was fixed by Mercedes Benz [ BENZE BUSCH of NJ ] back in to 2018 and now it is doing it again.I Contacted the dealer again about this and they refuse to repair saying Vehicle is out of warranty.I also contacted Mercedes Benz corporate Headquarters and they refuse to acknowledge the problem.Obviously this is a defect in the vehicle. I researched that they have had similar problems with other vehicles SUN ROOF problems and they acknowledge those facts and repaired them. I previously filed a complaint with the NHTSA ID #11478665 but it seems that you didn't have all the facts. Please look into this matter again now that you do. Thank YOU

The turn indicators stop working suddenly and randomly giving inaccurate/false indication to the driver of the vehicle that indicators are turned on and no indication of turn signal to the other drivers that can be hazardous especially at the 4 way stop signs where other drivers are assuming that vehicle is going straight where as the vehicle is intending to turn left but it is doing it without the indicator due to sudden failure of turn signal indicators and during lane changing. The hazard warning continues to work just fine and the turn indicator functions return to normal after turning the ignition off and back on. The occurrence of turn indicator failure is quiet often and has no set pattern.

After a weekend of incessant rain, while driving a short distance (10 minutes) , this low-mileage, well-maintained 8 year old SUV suddenly stalled, Engine appeared to have powered down and the yellow Engine light came up and pressing gas pedal didn't do anything. I was fortunately able to press the Power button once frantically and re-start it once more and pull over to the side but the car refused to power on thereafter. After investigations by the shops, it appears there was water leaking "through" the body of the vehicle and into the area below the interior of the car, short circuiting Fuel Driver and stalling the car (which they subsequently repaired after draining the water and replacing/re-programming the fuel pump driver) before handing it off for the leak identification work. The car was subsequently taken to a specialist shop to figure out the leak, and they are unable to identify any reasonable source of the water leak and insurance is so far claiming this is "wear and tear". In the course of the testing, the *same* issue happened again and the car stalled while driven by the shop personnel and they could hear the sound of water inside the cabin all the way up to the front. They are unable to identify the source(s) of the leak and at this point, the car has been unusable for over 4 weeks as Insurance continues to push back and the shop can't do the additional work to identify the source in the body without insurance approval. I made attempts to contact the manufacturer but their only available contact is their Customer Support (no email/chat option) who refused to discuss this as it didn't pertain to them directly and re-directed me to talk to my own insurance company. I even reached out via Twitter but got no response. This expensive luxury SUV is not just unreliable at this point but *dangerous* where there are mysterious water leaks under natural conditions like rain leading to car stalling while in motion.

IN MY NEIGHBORHOOD APPROACHING A STOP SIGN ABOUT 20 YARDS AWAY. THE CAR ALL OF A SUDDEN ACCELERATED AT A HIGH RATE OF SPEED. I WAS GOING TOO FAST TO MAKE THE RIGHT TURN AND THE BRAKES DID NOT STOP THE CAR. I ENDED UP RUNNING THROUGH THE STOP SIGN UP AN INCLINE AND INTO THE WOODS HITTING MULTIPLE TREES BEFORE COMING TO A STOP. THIS CAUSED OVER $18,000 DAMAGE TO THE VEHICLE (NOT INCLUDING DAMAGE TO THE UNDER CARRIAGE). NOT ONLY WAS THIS PRETTY FRIGHTENING BUT WHAT COULD HAVE HAPPENED IF I WASN'T IN MY NEIGHBORHOOD WHEN THIS TOOK PLACE COULD HAVE KILLED SOMEBODY. IT REALLY SHOOK ME UP. THANK GOODNESS THERE WERE NO KIDS AT THE BUS STOP. I WAS ALSO SURPRISED THAT THE AIR BAGS DID NOT DEPLOY. THE INSURANCE COMPANY TOTALED THE CAR SO NO ONE REALLY SEEMS TOO CONCERNED ABOUT THE CAUSE OF THE UNINTENDED ACCELERATION THAT TOTALED MY CAR WHILE DRIVING IN MY OWN NEIGHBORHOOD! THIS SHOULD NOT HAVE HAPPENED. I HOPE SOMEONE WILL CARE ENOUGH TO TRY AND DETERMINE WHAT HAPPENED SO THIS DOESN'T HAPPEN TO SOMEONE ELSE.

I WAS IN A COLLISION IN WHICH I REAR ENDED ANOTHER SUV. THE SPEED CONTROL DID NOT ENABLE AND I HIT THE OTHER VEHICLE HARD ENOUGH TO CAUSE $20,000 WORTH OF DAMAGE TO MY CAR. I BELIEVE THE CAR BRAKING RESPONSE WAS SLOW AND THE AIRBAG SHOULD HAVE DEPLOYED IN A CRASH THAT SIGNIFICANT, BUT IT DID NOT.

THE VEHICLE SENSORS ALL STARTED FLASHING, INCLUDING THE STABILITY CONTROL SYSTEM, PARKING BRAKE, TEMPERATURE GAUGE, ETC. THE SPEEDOMETER FLUCTUATED WILDLY, THE CAR WOULD NOT SHIFT OUT OF DRIVE AND WOULD NOT SHUT OFF. I WAS TRAPPED IN THE VEHICLE, UNABLE TO SHIFT THE CAR OUT OF GEAR INTO PARK OR NEUTRAL AND THE CAR WOULD NOT SHUT OFF. I HAD TO KEEP MY FOOT ON THE BRAKE, BUT I OBVIOUSLY COULD NOT GET OUT OF THE CAR WHILE IT WAS IN GEAR AND RUNNING. AFTER ABOUT 3 MINUTES OF TRYING TO GET THE CAR INTO PARK I WAS ABLE TO TURN OFF THE ENGINE. IT WAS EXTREMELY SCARY. THIS VEHICLE IS UNSAFE. *TR
