2014 Mercedes-Benz ML350 Problems

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.

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 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.

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.

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.

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

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.

After driving the car, the right/left turn signal switch fails to work (no signal is given both in the panel of the car and the external turn signal lights do not flash). However, the emergency flashers still work. I have searched the issue and found many occurrences on the Internet. Such a common issue should be a manufacturing quality issue and deserves a recall.

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 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`

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.
