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.

My name is [xxx] my vehicle cut off on me 3 times twice while stationary and once at an intersection. Found oil in engine control module due to failed cam position sensors. Oil has traveled through the engine harness to ecm causing oil to get into module and cause it to shut down but it did start back up. This is very dangerous and could cause serious injury to someone.

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, debra nolting.

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.

Engine stalled multiple times even though it has been serviced multiple times at multiple dealers.

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.

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. ".

When I start the engine, it makes a sound loud and strange.

My viechle is loss of propulsion without warning on the freeway last week on a raining day. After brought the car to west covina dealer inspected the car is leaking water that has entered the spare wheel well, the accumulated water could intermittently contact the fuel pump control unit caused loss propulsion. And there are some circuit boards and wires damaged due to a water leak and not drive able. The west covina mb dealer is refuse to fix until mbusa responsible for the cost. Please help what other option we have about this issue?.

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.

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.

The seals on oil cooler fail which causes leaks oil dropping on roadway or oil leaking in engine compartment can cause a fire.

2007 mercedes-benz Ml350 defective balance shaft causing pause & stop in traffic this is a known defect and has been resolved previously in customers favor in class action and private lawsuits against Mercedes Benz USA. Mercedes refuses to take responsibility for a defective and unsafe build that puts everyone in the path of this cars life in jeopardy. Please for the safety of the public will you force them to issue a recall on the balance shaft before I have to get an attorney! balance shaft - unsafe!! balance shaft has made this a suicide/weapon on wheels. When driving the car will suddenly and with no notice lose power, slow down substantially or stop on its own and sometimes will not moved forward at all. This has happened in traffic and I was almost hit. This is very unsafe could kill me or anyone around me. Each time I have had to turn on emergency flashers, turn off the car and restart. I drove home with emergency flashers on all the way. 2 mechanics, including dealer advise this is a known problem for my year and model. Mercedes knows this is defective workmanship & they putting lives at risk. Now I have no transportation as this car is unsafe. I have been advised not to drive the car.
