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.

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.

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.

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.

Car engine light on. Took to service center. Required software upgrade. Cost $275. Car has 26K miles. This should not be an expense to buyer but should be a warranty issue. Very unhappy with Mercedes-Benz and unlikely to purchase you vehicle in the future. Also, no obvious instruction for checking oil level. Another ruse by Mercedes-Benz to wring additional $$ out if consumers.

April 12th 20018 I got in my Benz and started it and all the lights on the instrument cluster light up and should go of after a few seconds but the lights did not go of so I put the car in drive and the emergency brake will not release so I had to push really hard on the brake to stop the car I turned it of and waited a few seconds and strated it again so thai can reverse it back in the park spot however when I put the sun in reverse it started going forward and all the lights are still on and the emergency brake still will not release so I keep pushing really hard on the brakes and put the sun in park and call Mercedes of sarasota fl for the second time after a scare like this Mercedes said that the sun was fine. Well at this point I was forced to get rid of my 4 year old SUV because I do not trust driving it no more an SUV that I fully paid for and was not expecting to had to get rid of it so soon.
