2017 MERCEDES-BENZ E300 Complaints

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.

MY check engine light has come on and the code is P052E71 stating Crankcase Ventilation Valve has a malfunction

have engine light on, and error code p052, which is a PVC malfunction. It is a common issue happens to a lot of MB owners. Mercedes Benz refuses to have the replacement covered by extended warranty.

The contact stated that while attempting to park the vehicle, the power steering assist failed with the "Steering Malfunction, Increased Physical Effort" and "Active Brake Assist" warning messages appeared on the instrument panel. Due to the failure, the vehicle was towed to an independent mechanic where an attempt was made to repair the power steering failure; however, the repair was unsuccessful.

The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 59,000.
