I was moving my car from one parking space to another space in front of my house. As I was pulling into the new space, I stopped to check the position of my car. As I lifted my foot off the brake, the car unexpectedly started to lurch forward. When I released the brake pedal, the car suddenly accelerated and proceeded to jump the curb and run into the front of my house. Luckily, no one was injured. There was some damage to the exterior of my house. I have reported this issue to the car manufacturer, Mercedes Benz. In response, they have opened a case to research it further.

My vehicle: (1) smells of gasoline through the vents. The smell of gasoline is SO STRONG that I have had to pull over and get out of the vehicle. My car has 104,000 miles on it. Not a lot of miles for a 2016. There are NO warning lights on indicating a problem with the vehicle. (2) The silver trim/coating that covers the window buttons and around the entire dashboard has bubbled overnight and is flaking off. It constantly cuts fingers and arms. (3) Approximately 5 months ago the headliner in the car started buckling.

With cold weather most w205 Mercedes, and specifically the one I have which is a C300 2016 starts having a strong Gas smell when I start the car at cold, and with the cold weather, the smell is getting stronger. There is already a class action going on in a different state concerning that issue, and it is probably a major and safety concern issue in those cars as a hose is a leaking fuel whenever the weather is cold. I ried with the dealership and they said no recall or anything for that issue yet.

2016 MB 300 C, AWD at 87000 miles started giving gas fuel smell when parked in our garage after driving. I took to a local Foreign Car Repair facility and they found a fuel leak at the fuel injector pump. The mechanic changed the Fuel Injector Pump (Bosch) at a total cost of $745.31. Since the change in the pump, the smell has stopped and I feel safe. Who is responsible to reimburse this cost to me?

A strong fuel odor coming from the car, we tried to get the dealer to repair it under warranty and they said, over fueling was causing it, however with the tank half full it does still smell a lot like gas, a strong odor you can smell it outside, they don't want to take responsibility on it, after warranty expired they came up saying something is wrong with my fuel system that needs to be repaired but its not covered by warranty, there are a lot of complaints but they want people to pay for this, we are afraid this could start a fire while driving, or even worse burn my house down

There is a raw fuel smell inside the cabin of the car when driving. I looked online and found that there is a lawsuit against mercedes-benz for faulty fuel lines that they are refusing to repair. I am having the same issues with the fuel lines as countless other people have where the rubber hoses are failing prematurely. I have a 2016 c300 with only 37,100 miles on it that is kept up on and the dealership is saying that the fuel lines are typical wear items and that the cpo warranty does not cover the repair. This is a safety issue as it could cause a fire and leaking fuel into the environment and fuel lines should not need to be replaced already.

The vehicle has a strong gas smell when the vehicle is idling. Dealer changed the 2 fuel lines and clamps. It's common problem in w205 c300 cars. The car was under extended warranty and the dealer refused to cover it under warranty even though the car has 29k miles. There should be a recall for these fuel hoses.

Gas smell coming through the vents started off every now and then and became more frequent. Pulled it in the garage and the gas fumes made the total garage smell. Took it to the dealer and they said it is fuel line, that sits near the engine. It is in the shop now. After googling I see several other people have had this issue with this car. They cannot tell me yet what caused the problem, I am waiting to hear that

I purchased my mb c300 used certified and had noticed a fuel smell. I spoke to the dealership and they said it was normal with mb and nothing to be concerned with. I have now had the car for about 5 months and took it to my local mb dealership to find out what is going on with the smell and they said it was a known issue with this make model and year and it is nothing that will cause harm.well it is now cold outside and the more I use my heat the more the smell comes.I can literally smell gas in my house from the car just being (not on or running) in my attached garage. This is definitely a health issue because I feel like I may pass out if I stay too long in the car with the heat on. Something needs to be done about this besides being told it's a known issue. If its widely known why has there not been a recall on it yet. I also do not understand why my warranty /extended warranty does not apply to this

There is a very strong gas smell when the heat and/or defroster is turned on. The higher the heat is turned up'the higher the gas smells. The smell lingers when the car is not running/cut-off. I have noticed that the strong smell of gas does not occur when the air is turned on'it only smells when the heat is turned on. It is so strong'it would literally knock you out.

Fuel line leak, smells like gasoline when heater is turned on.

Filed Dec 18, 2019 · Fuel system · 33,100 miles · CA

Hose clamps attaching the high pressure fuel line leading from the firewall-mounted fuel pump to the central fuel rail failed to maintain a tight connection. This leads to fuel leaking past the hose clamp connection into the open engine compartment during cold weather (sub-40 degrees fahrenheit) while the engine is running. When the ambient temperature in the engine compartment rises, either by environment or by heat generated from the engine, the fuel leak subsides. Symptoms when this occurs are a very strong fuel smell in the passenger compartment and also, upon further inspection, observation of liquid fuel pooling on the top side of the engine compartment under tray. Internet research also indicate that this is a fairly widespread problem affecting at least 2015-16 w205 model vehicles, and that multiple mercedes-benz dealerships in the united states have communicated verbally to other customers that this is a "known issue".

In february 2019 the c300 engine light came on, took the vehicle to the dealer and they said it was a bad catalytic convertor, and the dealer took three days to repair it. Three weeks later in march 2019, while driving 25 miles per hour straight on a residential street the car shut off without a sound, all the lights on the instrument cluster lit up, and the car coasted to a stop on the side of the road. I trie to restart the car, the starter made noise but the engine would not turn over. I called roadside assistance and did the three time lock and unlock routine, and the car would not start. After towing the car back to the same dealer, they told me the car was showing no codes, the issue could not be replicated and the car should be fine to drive again! I'm now afraid to drive the vehicle, and the dealer is refusing to fix it.
