2017 Mercedes-Benz E-Class Complaint Log

My car is not accelerating when I shift into drive or reverse. It says “reversing not possile-service required” error. Out the blue. There is a known recall on these model cars but Mercedes benz is saying its vin specific and mine is not covered even though I am experiencing the exact same issue. Recall date- 2017-02-07 Recall no. 17V078000

The contact owns a 2017 Mercedes-Benz E400 Coupe. The contact stated that the silver metal coating on the seat release lever was rough and jagged on both driver and passenger sides of the two door vehicle. The contact's son had grabbed the front seat release lever to access the rear passenger’s side seat and cut his hand. The cut was approximately 2-3 inches long. No medical attention was needed. The vehicle was taken to the dealer, and the contact was informed that the failure was common with the vehicle and that the coating was known to peel due to heat. The contact was concerned that the failure occurred as his vehicle was stored in the garage and sustained less heat exposure due to its maintenance/care. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 42,000.

The contact owns a 2017 Mercedes-Benz E300. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The message "Reverse not Possible - Service Required" was displayed. The contact pulled over to the side of the road and turned off the vehicle. The contact waited for approximately five to ten minutes, and the vehicle restarted. The vehicle was taken to the dealer, where it was diagnosed that the electronic shift lever had failed. The vehicle was repaired. The contact picked up the vehicle from the dealer, and two days later, the same message was displayed. The contact stated that on a separate occasion, while driving at an undisclosed speed, the vehicle failed to accelerate as intended while depressing the accelerator pedal, and the vehicle stalled. The message "Reverse not Possible - Service Required” was displayed. The vehicle was coasted to the side of the road, and the contact waited before restarting the vehicle. The vehicle was taken back to the dealer, where it was diagnosed that the Transmission Control Module (TCM) had failed and needed to be replaced. The vehicle remained at the dealer unrepaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 144,000.

Strong smell of Fuel or exhaust fumes in the cabin, while vehicle is idling, parked or stoped at the light.

The Air bag light just came on when I turned the car on I had it checked by a mechanic and by an electrician. The code is B000113 The Squib For The Driver Airbag (Stage 1) Has A Malfunction. There Is An Open Circuit. They checked the clock spring it’s plugged in and even tried using a new air bag but they believe the clock spring is broken.

The contact owns a 2017 Mercedes-Benz E300. The contact stated that while driving at an undisclosed speed, there was a strong gasoline odor entering the vehicle through the vents, and the odor was on the interior and exterior of the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer for an oil change; however, the vehicle was not inspected or repaired. The contact stated that the failure persisted. The contact related the failure to NHTSA Campaign Number: 21V961000 (FUEL SYSTEM, GASOLINE); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was approximately 59,000.

I am writing to formally lodge a complaint regarding serious and repeated issues with my 2017 Mercedes-Benz E300, purchased and serviced exclusively by authorized Mercedes-Benz dealerships. 1. Repeated OEM Run-Flat Tire Failures Within the past two years, I have been forced to replace nine OEM run-flat tires, including:    •   3 replacements at Mercedes-Benz of Tysons Corner, VA    •   2 replacements at Goodyear Tires, Cattlemen Rd., Sarasota, FL    •   4 additional replacements at certified service centers These failures occur under normal driving conditions, often without visible punctures or road hazards, and at safe speeds. Each tire replacement costs approximately $550, plus towing, diagnostic fees, and rental car costs. The financial and safety burdens are substantial, and this level of tire failure is not normal for any vehicle—particularly a low-mileage, luxury sedan. 2. Electrical/Dashboard Recording Malfunction My dashboard service history fails to record service visits, even when performed at Mercedes-Benz dealerships. This is deeply concerning as it compromises vehicle resale value, warranty tracking, and transparency of maintenance records. Despite multiple visits and attempts by service centers, the issue persists without resolution. 3. Financial Impact and Brand Reputation The total cost of repeated tire replacements and unresolved electrical issues has reached several thousand dollars, despite my vehicle having relatively low mileage and receiving all recommended service at authorized dealers. This experience is completely inconsistent with the quality and reliability promised by the Mercedes-Benz brand. I am requesting the following:    •   Full investigation into the defect rate of OEM run-flat tires on the 2017 E-Class models    •   Immediate inspection and repair of the dashboard/electrical recording issue at no cost to me    •   Reimbursement for tire-related costs and associated expenses incurred due to repeated failures.

See attached document for complaint.

When using Map apps through CarPlay, I’ve noticed two consistent problems: Inaccurate Vehicle Speed: The carplay speedometor does not match the the actual speedometer of the vehicle, which seems always 1.6 times higher than the actual(seems to be the metric confusion from mph to kmh). GPS Drift: The location shown on the map is frequently ahead of my actual position, which causes navigation directions (especially turns and exits) to be slightly mistimed. However, when the speedometer is correct, the GPS drift issue would disappear automatically. So I assume that these two issues are correlated. These issues can be confusing and potentially unsafe while driving. I’ve tested other navigation apps on CarPlay and found they do exhibit the same behavior, so I suspect the issue may be general to Mercedes E300 and probably other vehicles. I did a bit of research and found it to be a common issue of Mercedes E300 2017. Please see attached link for the threads from MB forum. https://mbworld.org/forums/gls-class-x167/843643-wrong-speed-limit-detected.html Thank you for your assistance, and I look forward to your reply.

Mercedes-Benz E300 is affected by a Transmission Control Module (TCM) recall, you might notice these symptoms: - Delayed or rough shifting: The transmission may hesitate or struggle to change gears. - Slipping gears: The car might unexpectedly shift out of gear or fail to stay in the correct gear. - Unresponsive transmission: You may experience difficulty accelerating or feel like the car is stuck in a lower gear. - Warning lights: The check engine or transmission warning light may illuminate on the dashboard. - Limp mode activation: The vehicle may enter a fail-safe mode, restricting speed and performance to prevent further damage.

The instrument panel that displays the digital speed, warning lights, etc. went black suddenly when turning on the car. It came back on suddenly while driving on the highway but after the car was turned off and restarted, the instrument panel has remained black. This is a huge safety issue as there is no warning light indicators, merging lanes does not signal if another car is present, among many other concerns. The vehicle has been inspected by mechanic. There was no warning indicators that instrument panel would go black suddenly. It happened in February 2025.

Crankcase ventilation system has failed. Spending $1700 because Mercedes won’t fix it because it’s a known issue and requires a lot of work. They left my car sitting in their parking lot for a week. I have the screen shots to prove it.

The automatic breaking assist is malfunctioning most of the time it just gives me a warning on the dash that it is limited a few times it has bumped the brakes briefly like it was sensing something in front of the car the perimeter sensors are malfunctioning as well like it’s sensing something all around the car very close then those sensors completely shut off and don’t work again until the car is shut off and started again

A warning saying Front Right Malfunction Service Required. I took my vehicle to a mercedes dealership to have my vehicle inspected. I was told that the Airbag seat cushion/weight sensing control unit all needed to be repaired/fixed. I have an extended warranty but this was not covered. I was told my Airbag might not be deployed if I was involved in an accident and someone was in my front passenger seat. "No one should ride in the front passenger seat until this situation is taken care of." I feel strongly that this should have been covered, plus it should've been a recall on this. It's a real safety issue!!! This need to be on the recall list for all mercedes or other vehicles with this particular issue.

While getting in to start my vehicle I got a message code on my screen saying Steering Malfunction, Increased Physical Effort. I contacted Mercedes USA and was told they had a recall on my vehicle which is a 2017 E300 Mercedes Benz. The recall effected vehicles made from July 29,2016 - February 14-2017. My vehicle was within this range being as though it was produced in 08/16. My car only has around 20k miles, basically a new vehicle inside and out. Even though my vin # is not showing as being part of this recall, I'm having the exact same issue and would like my vin# to be included. Thanks kindly.

P052E code. my car is only have 18455 mileage.

Smell of Gas coming from the the fuel line, and the radio changes stations on its own

The vehicle is getting stuck in parking and can not shift out of park. The issue first happened at the dealership when looking into an auxillary battery issue which has since been resolved. After over 30 minutes of trying to resolved the dealer was able to get the vehicle off the lift and switch the gear back into drive. Since then two days later the batteries were replaced and the same issue happen again (stuck in park) and now I see a transmission light on as well. I am not sure if the dealership noticed this when they had the issue in the shop. There was a previous transmission recall on the vehicle, which Mercedes said was previously addressed. My concern is that this can happen while driving which would be an extreme safety risks to myself and others. I don't believe I had any gear shift repairs since I owned the vehicle and the recall for my specific VIN may have been missed or not fully addressed. As of now I am unable to operate the vehicle and would like a recall reissued to resolve the problem. Thank you in advance for your assistance.

I am writing in regards to a constant issue that a great percentage of people including myself, are experiencing with the engine within the 2017 Mercedes E300. The cam adjusters are easily going bad or are malfunctioning causing the timing in the motor to be defected which makes the car stall and shut off even while driving. Giving that this is happening to a great amount of people with this particular vehicle across the US, we feel that mercedes benz should take some responsibility in fixing this issue and not just post bulletins on the problem, cause its a safety issue and it costs people alot of money for a defect of this sort.

The car is running poorly. Smell of fumes inside the car. Not drive able due to risk of engine damage including fires and exposure to dangerous fumes. Part is on back order and that is not a guarantee that the part will not fail again after fixed. Many people report continual replacement of the part. Positive Crankcase Ventilation Regulator Valve Performance: The valve for crankcase ventilation has a malfunction. Crankcase ventilation actuator is blocked .

Fault code p052E71, the crankcase ventilation valve is faulty. The actuator is blocked. Second time having this issue.

Strong gas fumes smell from vehicle when parked. Issue starts around 50k miles. No lights on dash or anything. Multiple people in forums online experience the same issue around the same mileage. Some say it's a leak from fuel lines to the fuel pump.

PCV FAILURE causes engine light code and emission problem

Check engine light came on and then complete engine failure. Cracked #1 piston, and engine destroyed.

failed or malfunction in PCV valve. Common issue in all 2016-2018 C300, E300, and GLE300. Multiple failed complaints on the part. Nationwide backorder on the part. No recall issued for this common problem. No help from dealerships, will just put you on a waitlist for a nationwide back order.

PCV regulator valve failure at69,000 miles on my 2017 Mercedes E300.. I understand this is common before 100,000 miles with the four cylinder turbo, I feel there should be a recall and be replace at Mercedes dealers cost. (to replace cost is around $2,000 about 7 hours labor I was told)
