general problems of the 2015 Mercedes Benz C300 - part 2

I took my car in for service b and was told the low pressure fuel lines were leaking. It is a fire hazard, so it cannot be ignored. The car is 5 years old and has been meticulously maintained. It cost me $750 to repair, and my vehicle was out of manufacturer's warranty.

Intermittent fuel leak. Real bad gas smell in cabin coming through the vents. Driver side, in back, down between the engine and body. The fuel lines are pressurized, so it might only leak when the pressure builds up. I kept getting a strong gas smell the garage after parking for long periods.

When vehicle is cold the whole cabin smells like gas or when put heat on. The smell is very heavy when vehicle is stationary when drive it calls down, but at a light it comes back. Mercedes has many complaints about this problem.

A few days ago, I began smelling a strong smell of gasoline when I drove my car. This went on for several days, so I took my car into the dealership. As soon as I described my problem to the service staff and before they checked me in, they asked me if the model was a mercedes C300. When I replied that it was, they said that they had seen this problem quite often on this model. Given the low mileage of 23,115 miles on my car, a fuel line leak would not normally be expected to occur. Considering that fact along with the reported commonality of this issue, I am concerned that, for other drivers with this potential problem, the symptoms may involve more than just the scent of gasoline and result in car fires or accidents. Neither the dealership nor corporate mercedes have been responsive to my concerns.

Fuel system, gasoline. There is a fuel smell coming inside of the car through the front filters. We have changed fuel injector ring however the smell is still there. Mercedes dealer is not willing to do anything about this. I see there are recalls on the same models produced a year prior. Believe this might be the same issue that was not resolved .

There is a fuel hose (parts number: 274 070 3500) connect to the high pressure pump in front engine area. The fuel hose was fastened by a clamp (not sure the parts number) . Because of the design flaw, this clamp will loose since it's a snap joint assemblies not tighten by screws. Under this situation, the fuel hose will loose and affected by thermal expansion, this problem will cause fuel leak/seeping. We can smell fuel near the pump before we start car in cold in the morning and this smell can be smelled until the engine working into the normal operating temperature or when we turn on the ac or heater . Fuel is a very critical safety problem and usually we cannot take notice of this potential problem. This is been happening since 11/19/2019 the date when I bought the car till now.

Strong fuel smell in the garage and inside the vehicle during cold start after the vehicle is parked for 8-12 hours. The issue is even more noticeable during colder weather (below 40). The dealer acknowledged this is a common issue for C300 and is due to a defective clamp on a fuel line. The vehicle is at 44,000 miles and 6 mounts out of warranty. The fuel leak is a safety issue and should be repaired by the manufacturer especially if is a well known defect.

Heavy fuel/gasoline smell around engine bay began approximately 2 years ago while the car was still under original 5 year warranty. Fuel smell would persist outside of the vehicle despite the vehicle not being driven for multiple days. When driven, fuel smell would permeate into the cabin of the vehicle and cause mild headaches to the occupants. Taken to dealer to find cause of smell and was advised that there was nothing wrong with the vehicle. Fuel smell continues to persist since it was originally noticed without change and vehicle is no longer within warranty period. Recently, this vehicle was taken back to the same dealer for servicing for an unrelated issue. Told the service representative that there was a fuel smell that continues to linger around the vehicle when parked and inside the cabin. This inspection revealed leaks from two fuel lines and technician recommended replacement. Warning lamps, messages, or other indicators from the car never appeared.

I smelled fuel in my garage occasionally for the past 4 months. I assumed in was the gas heater but when I park my car in others garage I smelled fuel. A friend suggested it might be my car. I took my car into service for my 50k service and asked if they could look into. Mercedes benz informed me it is wet around the fuel hose connector. Before I only smelled it twice a month in the garage. After one I got it back from service, I smelled fuel inside the car while I'm driving.

When I got my mercedes 2. 5 years ago I would always notice a very strong gas smell that would come very randomly. I would have to open my windows for the smell of fuel to go away. I presented this to the greenway mercedes dealership 2x verbally and they told me that it is just a "mercedes thing" and everything is ok because it is not "visibilly" leaking fuel. Which it was not. However, the smell of the fuel is extreme, it would happen to me through out the year (in the summer and winter, regardless of temperature) randomlly. I would have to leave the garage ASAP when I turn on my car just in case the smell of fuel was extreme because my parents would tell me that it would even come into the house. I thought I was crazy to think this was normal and just a "mercedes thing". But then I got a letter on August 2021 and did some research and saw I was not the only one and there is a class action lawsuit -mercedes sent a letter on August 21 announcing they will extended the limited warranty of the "fuel hose connected to high pressure fuel pump" from the original warranty of 4 years/50,000 miles to 10 years/120,000 miles. However, this does not help, they are still saying it is a wear and tear and refuse to replace the defected manufactorer part and insist it is not "seeping fuel" from the connection at the fuel pump, so it is not under warranty. I am confused as to why this is not a recall? extending the warranty did nothing to help mercedes owners at all. They continued to claim it is "wear and tear so that is why the fuel is sweeping at a different location" as well, two dealerships told me it would take them 24-48 hours for them to just inspect my car to see if it is covered. This extension did resolve anything, but made sure the dealerships deny even more. Now, I have to continue to leave my garage within 30 sec. So I don't suffocate the cats that sleep in the garage or have my family smell the fuel as I leave. And to open my windows so I can breath fresh air.
