The contact owns a 2017 Mercedes-Benz E300. The contact stated that the vehicle was purchased on October 20, 2023. The contact stated that when she entered the vehicle the following day, the exterior of the vehicle smelled of gasoline. The contact stated that the fuel odor had become so abnormally strong inside the vehicle, causing her mother’s asthma to flare up. The vehicle was taken to the dealer. The vehicle was diagnosed with a low-pressure and high-pressure fuel line leak in the engine compartment. The contact was informed that the fuel line and fuel pump needed to be replaced. The vehicle was not repaired. The dealer advised the contact that the parts to complete the repair were ordered. The manufacturer was not made aware of the failure. The failure mileage was approximately 31,806.

While driving the car on the beltway, the car unexpectedly and suddenly lost drive power. I pushed on the gas pedal and the car did move forward in a jerky motion. A minute or two later, the car again suddenly lost drive power. Again, I pushed on the gas pedal and the car jerked forward. After, these two episodes above, the car behaved normally for the rest of my 90 drive.

The contact owns a 2017 Mercedes-Benz E300. The contact stated while coming to a stop, the vehicle shuddered. The check engine warning light was illuminated. The contact stated while accelerating from the complete stop, the vehicle hesitated to respond. The contact was able to continue driving at a slower speed. The contact stated that the failure had been recurring while driving and the vehicle failed to exceed 60 MPH. The vehicle was taken an independent mechanic, where the spark plugs, ignition coils, and the fuel injectors were replaced; however, the failure persisted. The mechanic determined that there was low compression on cylinder #1, and that the engine needed to be replaced. The vehicle was not repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 82,000.

The entire driver instrument panel screen went blank, after going blank and coming back on a few times while driving. This is EXTREMELY dangerous. Now, the driver cannot see the speed, odo, fuel gauge, indicators or anything at all. I hope you please investigate and initiate a campaign and get this resolved from Mercedes.

Engine failure due to piston crack. Seems like it is a common issue for mercedes models with this specific engine. A lot of people have their engine needing to be replaced at very low miles such as 10k miles 15k miles. Vehicle was always been serviced on time. Now I need a new engine. Manufacturer needs to take responsibility of this engine defect

Car will loose power unexpectedly and start shaking badly. Check engine light comes on flashing. Vehicle gets towed to shop to find loss of compresión on cylinder one. Mercedes Benz forums full of this type of issue. Shop says repair is to rebuild or replace engine. Vehicle available for inspection.

The car lurches forward upon accelerating. Other times the car lags when accelerating after slowing for a dip or speed bump. This has caused me to almost be hit from behind on multiple occasions. My car has been in the shop multiple times since I bought it.

Having a Mercedes was my dream since I was a kid and I’m completely heartbroken to have to file this complaint. I’ve been working literally my whole life to finally be able to afford my 2017 E300. I purchased it from Autobahn Motors in Belmont, California in August 2020. My car has ~48,000 miles on it and I still own approximately $14,000 on the car as of today (5/20/2023). When I was driving on the highway my car engine light came on, started to violently shake, and I thought it was going to stall out. I immediately took it in to my mechanic and he told me that piston #1 is broken and the spark plugs are melted! Premature engine failure. I can no longer use my car until I get my engine replace! I’ve gotten one quote and it is approximately $15,000! I don’t even have 50,000 miles on my car. I saw a large volume of complaints online for the M274 engine including a class action lawsuit that have exactly the same issue as what my mechanic diagnostics is showing (broken piston #1 leading to premature engine failure). This is a huge safety concern and needs to be investigated immediately and corrected by Mercedes Benz before someone gets hurt or dies from this failure. For the price I’ve paid, still owe, as well as what the repair would be is completely unacceptable. I need my car for work and I’m also a parent so this is creating a huge inconvenience and financial hardship. Mercedes must be aware of this problem and held accountable for there negligence on correcting this issue.

The contact owns a 2017 Mercedes-Benz E300. The contact stated while driving approximately 35 MPH, there was an abnormal gasoline odor entering the vehicle. The contact stated that he did not notice a warning light being illuminated. The contact had taken the vehicle to a local dealer who was unable to determine the cause of the failure. The contact then drove the vehicle to an independent mechanic who diagnosed the vehicle and determined that the fuel rails and fuel injectors needed to be replaced. The vehicle had not been repaired. The independent mechanic advised the contact that the failure was related to NHTSA Campaign Number: 21V961000 (Fuel System, Gasoline). The manufacturer had been informed of the failure. The failure mileage was approximately 68,000.

There was a smell of gasoline in and outside the car when the car was idling. Also, a smell of gasoline in the garage around the parked car. Also a smell of gasoline after starting the car, that went away after driving. I called the service department. They gave me an appointment one week later. I have no complaints about the service dept. When the car was repaired several hours later, the report stated "found seep at fuel hose to pump", and then, "replaced upper fuel hose to high pressure fuel pump". They told me it was no charge because they knew about this problem happening in their vehicles and had extended the warranty for it. I was/am very concerned because(1.) if I had been in an accident, could have more easily been a fire? (2.) Mercedes knew about this and to my knowledge have not let customers know, (3) I kept up with all maintenance/service visits and I was never told to be aware of this possibility, (4) when reported by me, there was no procedure in place to prioritize scheduling this repair. I may be wrong in my analysis and do not want to cause anyone any trouble. I just think if one car fire can be avoided that is important. If my thinking is incorrect, I apologize sincerely for my reaction to this situation.

2017 Mercedes Benz E300 38k miles Parking brake malfunction. Replaced rear two Electric parking brake module /actuator. Still have the same problem. Mercedes Benz are claiming it to be ABS module.

I've owned this vehicle for a few years and don't use it that often. I purchased it as a certified so I thought everything had been checked out. However, not too long ago i took my wife and my son who was home from college out to dinner. When we left and started back to the car, my son was ahead of us and didn't think when he lifted the door handle. The alarm came on and I was still quite some distance from the car. That didn't seem right so when we got home, I walked quite a distance from the locked car and had him try it again. Again the door came open when he lifted the handle and the alarm came on. After resetting it, I locked it again and this time had him try all handles. They all locked except the rear (passenger) door on the driver's side. That convinced me that something was wrong. I took it to the dealer, the same place I purchased it from three years ago and they said the door lock was bad and it would cost me $800 to fix it. I thought that was a little steep and told them it was probably like that when i got it. That didn't mean anything to them. I am thinking of trading the car so I don't want to spend more money on it so I told them to hold off. I was searching for that problem on the Internet and I ran across a recall notice that identifies that same problem on the same door in a number of other model Mercedes, and I thought, that seems like a coincidence. What are the chances of that? The same manufacturer, the same year, the same problem on the same door. Onl

The sunroof is leaking when it rains on the front upper left side by the driver. My safety is act risk because of the water coming in the car distracting me from driving and not sure if the water is damaging the electrical system in my car.

There are three main issues: As the weather got cold here in NJ, whenever the car is started in the morning, there is a strong fuel smell inside the cabin. Also there is a lot of fumes that smell gasoline. I think it is safety issue. The auto braking does not seem to operate right. I do not see any error message, but it had never tried to avoid a collision when I have tried other cars that would have normally applied the brakes in those situations. The garage door opening function does not work as soon as the ignition is turned off. This is an electrical issue in my view.

There is a smell of gas inside the cabin coming from the vents

Vehicle emits a strong odor of gasoline when cold. It was mainly noticeable on the outside of the car at first, but now when I turn on the air inside the car (not on AC mode), I started smelling the odor of gas in the cabin. I have taken the car for possible repairs, but am told on two separate occasions by an independent service center that the odor can not be duplicated. There are recalls for the same issue on different models, but as of yet, not on this particular year model. I have notice that when the car sit overnight and when I open any door, trunk or push the lock button on the car's remote, a few seconds later, it starts emitting the smell of gasoline. The car is always parked overnight inside my garage, hence the smell is very strong.

STRONG PERSISTENT ODOR OF GASOLINE IN THE CABIN ON COLD START

LOW PRESSURE FUEL LINE NEEDED REPLACING. THIS WAS DUE TO A FUEL SMELL IN THE CABIN WHEN COLD. MERCEDES INDICATED FUEL LINES ARE CONSIDERED WEAR AND TEAR AND EVEN THOUGH IT WAS LEAKING , WAS NOT COVERED UNDER PRE OWNED WARRANTY OR RECALL. THE FUEL LINE APPEARS CRACKED DUE TO MISINSTALLATION VS RUBBER CRACKING DUE TO AGE AS ONE SIDE WAS PRISTINE AND THE OTHER HAD A CRACK IN IT. THIS IS NOTICEABLE AT IDLE , WHEN THE CAR IS COLD AND THE HEAT IS BLOWING.

ADAPTIVE HIGH BEAM WAS NOT WORKING - UPON INITIAL ACTIVATION OF THE HIGH BEAM THE CAR WOULD PROVIDE AN ERROR THAT THE CAMERA WAS BLOCKED AND IT WOULD NOT WORK. THE DEALER INVESTIGATED AND IT APPEARS A PIECE OF TRIM FROM INSTALLATION WHEN NEW WAS LEFT IN THE CAMERA AND IT WAS NOT INSTALLED PROPERLY. THIS IS AN ISSUE IF YOU SUDDENLY NEEDED THE HIGH BEAMS ON AND THE CAR MAKES YOU PROCESS THE ERROR FIRST. THIS COULD IMPACT ANY DRIVER AIDS USING THE MULTIFUNCTION CAMERA.

STRONG SMELL OF PETROL IN THE MORNINGS, SEEMS TO BE UNDER THE HOOD. I INSPECTED THE FUEL LINES FROM THE FUEL TANK TO THE ENGINE UNDERNEATH AND COULD NOT FIND ANY DRIPS OR WETNESS. DID SOME RESEARCH ONLINE. THERE WAS A RECALL ON OTHER MODELS FOR THIS PROBLEM. I CALLED MERCEDES CUSTOMER SERVICE BUT THERE IS NOT A RECALL FOR THIS ON THE 2017 MERCEDES E300

WHILE IN MOTION, ENGINE STARTS VIBRATING AND THE CHECK ENGINE LIGHT COMES UP. TOOK IT TO THE MECHANIC AND ITS A BROKEN PISTON. THIS IS THE THIRD TIME THIS IS HAPPENING ON THE SAME ENGINE

ON SEPT. 10, 2020 WHILE DRIVING ON THE WESTBOUND LONG ISLAND EXPRESSWAY, NEAR EXIT 19,IN AN AFTERNOON RAINSTORM, MY 3 YEAR OLD MB E300 WAS FLOODED THROUGH THE REAR VIEW MIRROR MOUNT AND THE COLUMN ON THE DRIVERS' SIDE, SEPARATING THE WINDSHIELD AND DOOR. WATER CASCADED FROM THESE AREAS AND FLOODED THE FLOOR. ALL ELECTRONIC COMPONENTS ON THE FLOOR, UNDER THE FRONT SEATS, WERE SHORTED OUT. THIS BROUGHT THE CAR TO A COMPLETE AND SUDDEN STANDSTILL IN TRAFFIC ON THE HIGHWAY. THE ENGINE CONTINUED TO RUN BUT THE CAR WOULD NOT DRIVE OR MOVE, POTENTIALLY PUTTING MY LIFE IN JEOPARDY. THE SHIFT LEVER WOULD NOT PUT THE CAR INTO DRIVE, REVERSE OR NEUTRAL. THE CAR NEEDED A TOW ON A DOLLY OFF THE HIGHWAY AND IT CONTINUED TO RUN FOR HOURS. THE WINDSHIELD WIPERS WOULD NOT TURN OFF AND THE WINDOWS COULD NOT BE SHUT. JUST ABOUT EVERY WARNING LIGHT IN EXISTENCE WAS ON IN THE DASHBOARD. THE ENGINE WAS FINALLY SHUT DOWN, AFTER OVER 4 HOURS, WHEN THE CAR ARRIVED AT RALLYE MERCEDES BENZ IN ROSLYN, NY. THIS SUDDEN STOP, IN A RUNNING CAR, ON A LIMITED ACCESS HIGHWAY COULD OF BEEN DEADLY. THE CAR HAD RECENTLY BEEN SERVICED AT RALLYE MOTORS.
