This page combines three types of NHTSA data: recall campaigns (official manufacturer or government actions), owner complaints (unverified consumer reports), and crash test ratings (where available). A vehicle with many complaints is not necessarily less reliable — complaint volume correlates with sales volume and vehicle age. Recalls indicate identified defects, not overall quality.

Today at 1/27/25 630 pm my vehicle caught fire.i was told that the vehicle was subject to the Active Curve System (Recall 18V272) and Fuel Pump (Recall 23V010).
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.
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.
Driver side airbag malfunction without notice .serious bodily injury incase of an accident.
The contact owns a 2014 Mercedes-Benz ML350. The contact stated that upon starting the vehicle, the blind spot warning light illuminated. The contact was unable to identify if another vehicle was nearby. The vehicle was taken to an independent mechanic who determined that the blind spot detection system was inoperative. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 170,001.
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.
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`
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.
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.
The contact owns a 2014 Mercedes-Benz ML350. The contact stated while the vehicle was idling in the driveway, the vehicle stalled. The contact stated that AAA added fuel to the vehicle, and the vehicle was able to restart and operated as needed. The contact stated that the vehicle was taken to the dealer for the recall repair of NHTSA Campaign Number: 22V955000 (Fuel System, Diesel, Fuel System, Gasoline), and the dealer installed a water drain plug on the vehicle. The contact stated that the check engine warning light was later intermittently illuminated. The vehicle was taken to Complete Performance, where it was diagnosed with fuel pressure failure. The contact replaced the gas cap; however, the failure persisted. Additionally, the contact stated while driving 45 MPH, the vehicle stalled while there was sufficient fuel in the fuel tank. The contact was able to pull over to the side of the road. The vehicle was able to restart after fuel was added to the vehicle. An unknown dealer was notified of the failure and informed the contact that the fuel pump was not previously replaced during the recall repair of NHTSA Campaign Number: 22V955000( Fuel System, Diesel, Fuel System, Gasoline). The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 60,000.
The contact owns a 2014 Mercedes-Benz ML350. The contact stated that while driving at 35 MPH and accelerating above 40 MPH, the vehicle failed to accelerate above 40 MPH before it lost automotive power. The vehicle was driven back to the residence. The vehicle was diagnosed by the dealer, and the failure was associated with NHTSA Campaign Number: 22V955000 (FUEL SYSTEM, DIESEL, FUEL SYSTEM, GASOLINE); however, the VIN was not associated with the recall repair. The vehicle was repaired out of pocket. The manufacturer was notified of the failure. The failure mileage was 115,000.
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.
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 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. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.
Blind spot assists and turn signals go out without warning. This model should have been included in the previous recall for timing. Having the same issues as other recalled cars.
See attached document for complaint
Traveling on my way home from Arizona and as my back was hurting turned on heated seats…I also had air conditioning running due to dogs in back seat…I started noticing what felt like a pinching sensation where my butt and legs meet…Stopped thr car at next rest area and noticed butt really hurt when I slid out of car…felt back there and area and hurt like heck..got into my Rv that a friend was driving and looked at it!! 2nd degree blisters/burns from heated seats!! 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! Plus, I want it fixed…!
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 .
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.
