Blow-by gases are mixed with oil mist and other contaminants that can harm an engine's internal components and contaminate the environment. How does the crankshaft ventilation work- When the vehicle is moving, airflow across the open end of the tube creates suction (a "draught" or draft) that pulls gases out of the crankcase. To prevent too much vacuum being created, the blow-by gases are replaced by fresh air using a device called a breather. The breather is often located in the oil cap the engine misfires, you may have trouble getting your vehicle up to speed. Misfires often happen when your vehicle is under load while accelerating. This can result in slow or sluggish acceleration or a jerking motion while pressing down on acc

Subject: Urgent Safety Concern Regarding Recall Campaign #2022030003 for 2016 CLA250 VIN# xxx Date: August 16, 2023 To Whom It May Concern, I am writing to express my deep concern and dissatisfaction regarding a recent incident involving my 2016 CLA250, VIN# xxx, which has raised serious safety issues for both myself and my passengers. Between July 15, 2023, and August 14, 2023, I experienced a distressing loss of power while commuting to work. The incident occurred while I was traveling in the high-speed lane on the highway, almost resulting in a major accident that could have led to severe injuries or even loss of life. During this period, the check engine light on my vehicle illuminated and subsequently turned off. Fearing for our safety, I promptly sought a vehicle diagnostic assessment at the Firestone Service center on August 15, 2023. The diagnostic codes returned indicated a "Fuel/Rail Low Power" issue. To my dismay, I learned that a recall (Campaign #2022030003) had been issued by the manufacturer for the exact problem I encountered. With this information in hand, I diligently contacted the local Mercedes dealership to address the recall. However, I was informed that my vehicle's VIN# was not included in the recall list. This contradicts the diagnostic assessment carried out by Firestone, which clearly indicated the need for intervention due to the "Fuel/Rail Low Power" issue. Given the alarming circumstances and the potential risks associated with this safety concern, I implore you to investigate and rectify this situation promptly. It is evident from the diagnostic results obtained from Firestone that my 2016 CLA VIN# xxx should be included in the recall list to ensure the safety of all occupants. I trust that the National Highway Traffic Safety Administration (NHTSA) plays a pivotal role in safeguarding the well-being of motorists and passengers across the nation. I kindly request your urgent attention to this matter to prevent any further incide

Car cannot be driven when gas gage shows a little bit less than tank. The range on the car showed almost 90 miles to empty on highway driving and all of the sudden the engine started to lose power and engine light came on, pulled to the side of road limping along at 20 miles per hour with gas pedal all the way to the floor and then engine shut down by itself after 2 miles. After engine shut down all lights on the dash board lit up and needed to turn off car. Restarted the car and the car would not drive in reverse, manual paddle shifter would not work at all, and driving a few yards was impossible. Car shut down a few times and then low gas light came on (two miles before that the range on the dash board was showing almost 90 miles to drive until empty) after this happened, I got towed and put some premium gas. Started the car (after about one hour of the first incident), the engine light was still on and started driving at slow speed to make it home. After a few hours/overnight started the car normal in the morning (no sign of losing power) and engine light turn off. Need to mention that car had fuel tank and other emission components replaced under warranty three months ago for a similar but not identical issue. Problem appeared to happen when tank is either almost full or almost empty and driving long distance on the highway.

Car cannot be filled with gas more than 7/8 of the tank. When filled full, the engine sputters and car start to stall/shake violently, engine loses power and engine light comes on and then engine shuts down by itself. After engine shuts down all lights on the dash board lit up and need to turn off car. This happens on both city road and highway driving soon after filling the tank. Almost caused an accident on the highway as I could pull fast enough onto the shoulder and get out of the way from other cars behind me on the highway driving at 60 miles/hour. After this happens, I had three options. Get a tow track and pull the car of the streets, drive the car on the highway at speeds no more than 25-35 miles/hour using the manual paddle shifters, or wait at least one hour on the side of the road after this happens and then drive the car with the engine light on. This happened twice and since than I am not putting gas more than 7/8 of the tank.
