This happened as a new car, only now, after it happened about 5 or 6 times, we came to know this weired and dangerous problem-it loses the power at a stop; at red light, and even when we tried to start to move. When it happened, at first several times, we were thinking maybe I did something, after 5 to 6 times happened to me and to my wife, we just came to understand it is such dangerous problem. Now, it happened again on friday and we went to the Mercedes dealer, we came to know more, many happen like this, we are not the first; Mercedes no solution, even they tried to find. So far, still no solution at all. The service guy declared that it only stopes at a stop!! They cannot do anything as Mercedes still no solution!! Will anyone drive such a weird car it stopes you at stop?? What happen

Vehicle loses power after a few hours of driving. This problem does not show any error message on the dashboard, and the dealer cannot fix this problem after multiple attempts. Last trip to the dealer which was 2 weeks ago, they insisted that nothing was wrong. Here are examples of how serious the problem is, I was stranded and had to shut the car down for 30 - 45 minutes to let the car reset before continue driving. I was stranded on grapevine while driving back from san francisco to los angeles. The car could barely pull itself up the hill, and freeway 5 was under construction without much service lane that I can pull out. I got lucky and got to pull out before big rig slam into my back. This car will sporadically loses power on surface street which almost landed me into a head on coll

Cuando enciendo mi guagua hace un ruido muy fuerte y se siente como si se va a apagar. El motor se puede romper en cualquier momento. Si se ha llevado a diferentes talleres para confirmar el ruido y me refieren que son mas de 80 guaguas que han visitado su taller con el mismo problema. No presenta ninguna advertencia cuando aparecio por primera vez. En el taller me dicen que se debe cambiar el motor por que son los motor stroker y eso puede causar un feo accidente. When I turn on my bus it makes a very loud noise and it feels like it's going to turn off. The engine can break at any time. If it has been taken to different workshops to confirm the noise and they tell me that there are more than 80 buses that have visited their workshop with the same problem. It does not present any warning

The driver's seat belt is locked and the retractor is not working without any reason. The front adaptive cruise control radar is also not working, along with the crucial blind spot sensor. Because of this, the vehicle cruise control (even without adaptive mode) is not working at all. This is a big safety issue and it is illegal to even drive this car without the seat belt working.

Seat belts will not extend. When trying to buckle seat belt, the belt retractor locks as you try to extend, preventing you from buckling your seat-belt. Affects both driver and passenger seat-belts. Intermittently happens and seems to be temperature related. More likely to happen when it is warm.

Tl* the contact owns a 2012 Mercedes-benz ml350. While at a stop light, the vehicle stalled without warning. In addition, the radio and air conditioner failed to function. The failure recurred numerous times. The vehicle was taken to Mercedes-benz of coconut creek (4250 sr 7, coconut creek, fl 33073, phone: (954) 406-1167) where it was diagnosed that the fuel pump failed, there was a leak in the air conditioning system, and the radiator failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The approximate failure mileage was 48,000.

The conrol to activate the windshield washer is a stalk mounted button on the left side of the steering wheel. Pressing this button will correctly cause the windshield washer to come on briefly, spray the windshield with water and follow up with a few strokes of the wiper to clear the windshield. The problem with this arrangement is that the similarity of the button on the end of the stalk on the right side, which places the transmission in park. Thus if you are traveling on the interstate, for example, you could easily confuse going into park with washing the windshield. My experience if you make this mistake is that the car will not go into park while the car is in motion, but will go into into neutral until the car fully stops. This could be a dangerous maneuver, especially in the r

The turn signals randomly stop working. Vehicle must be turned off and restarted to get signals to work again which only lasts for an unknown number of times. Major safety issue. Was almost rear ended with grandchild in car when turn signal that worked moments earlier failed and car behind me consequently almost hit me. Mercedes usa was contacted and was unwilling to remedy the problem. They diagnosed the issue as a defective steering column module that neede to be replaced. The estimate was almost $1300. The car has only 39,000 miles on it and based on research others have had this issue. Mercedes basically indicated that I was not a loyal enough customer to warrant compensation. I am forced to violate traffic laws at times because I try to not use signals when absolutely needed as I don'

When the car has been running for a while the directional signals stop working

The headlights are really dim. It's hard to see the curb in the night when driving from a road with no curb and entering a road with curb. *js

Mechanic found water in spare wheel well. Had to replace fuel pump. In February,2023, Mercedes Benz notified me of a recall, NHTSA Recall I D: 22V955 ; water intrusion in the spare wheel well. And, stated their local dealer would repair vehicle or reimburse me for the cost of repair, if I had the repair done already. I submitted receipts and documents pertaining to the repair. The Mercedes Benz Dealership refused to acknowledge the causal relationship between the repairs and the recall issue. And, refused me reimbursement.

My wife was driving home from shopping and noticed an accumulation of dust on the rear window. She used the rear wiper to clean it but it came right back, she repeated twice and gave up. Approx 3-4 miles later she heard a POP and red lights came on the dash, when she pulled over ASAP in a safe spot smoke started coming from under the hood. She shut the engine off and tried to exit the car to find the hood release under the dash but there was fire coming out from under the car. She closed the door, grabbed her purse and cell phone and got out quickly as possible, burning her ankle and singing her long skirt. She got approx 50 feet away, looked back and the entire car was ablaze, centered mid vehicle, as well as 4-5 spot fires along the road she had just traveled. Previous to the POP the car

I have own this vehicle on July 2023. I have recently noticed the exterior paint is peeling off quickly all over the body.

Oil was leaking from the engine which was the result of a faulty part that Mercedes has subsequently replaced with a new re-engineered part. The dealer indicated that the issue is systemic with all blue-tec m and g class vehicles which Mercedes will not cover the charge for. The repair requires that the engine be removed from the car because that it is the only way the part ($30) can be replaced. The resulting repair cost over $1900 in labor. We noticed the leak because there was oil drips in our garage. The service technician at the dealership noted that we had lost about a third of our oil and that the oil was covering the engine and it was also noted that the oil could have caused a fire if the part was not immediately replaced.

My VIN is not part of the takata recall, although similar models I.e ml350 4matic 2012 is. My car was involved in a high impact crash in which it was totaled. The airbags failed to deploy and resulted in serious neck and back injuries. The car was stationary on the highway as traffic slowed. A fast oncoming vehicle (70-80 MPH) failed to see my stationary vehicle and rear ended my vehicle without breaking causing it to crash in the car in front. The incident was sufficient enough to cause my engine to drop and the front crumble zone was fully utilized. A warning message appeared on the dashboard "left SRS airbag malfunction" see the picture attached. This is possibly a widespread issue affecting multiple classes of Mercedes benz cars.

I stopped at a red light. The 2012 ml350 engine stalled. I could have been in a accident. Luckily, the car behind me did not hit me. I had to start the engine again. *tr

While traveling at 55mph the steering suddenly felt very stiff and hard to move. Had to apply brakes when it seemed I couldn't negotiate a curve in the road. The steering returned to normal shortly after applying the brakes. The steering problem occurred again in a local shopping center parking lot at slow speed. Returned the car to the dealer service center. They performed a software update and stated they couldn't find any problems with the steering. Within 3 days the problem reappeared at slow speed while steering through barriers entering a local air force base. The next day (4 days after dealer service) the wife had the steering lock up at slow speed in a local grocery store parking lot. She could not move the steering wheel at all. She shut off the engine, restarted the engi
