Check engine lite with code P052E that is "Positive Crank Case Ventilation Regulation Valve Performance" at around 65K miles. This might pose danger with engine failure. the problem has been confirmed by an independent service center. Dealer said that this problem is common to the year and model of my car and that the manufacturer has replaced this piece in newer models. Since the manufacturer already know this issue and replaced the piece with a better one for newer model. I believe this part should be recalled and replaced by the manufacturer. it is crazy amount of money for the consumer to fix this.
2015 C 300 Mercedes Benz Crankcase ventilation/ oil separator is bad. Vehicle has only 50,000 miles. Please help, Mercedes should have this on recall, a lot of people has this same issue. Thanks
Got error code P052E when performing state inspection for my car. This looks like "Positive Crankcase Ventilation Regulator Valve" issue and have seen lot of people who owns Mercedes Benz reported this issue.
Looks like I am not the first one to complain about the strong smell of fuel on the driver side under the hood as well as inside of the vehicle. Upon further inspection it was determined that the fuel line at the pump is leaking fuel. My car has only 48k miles on it...How can such dangerous failure be ignored by MB for more than three-four years or longer?? Please note that this particular issie is leading the complaints chart. Based on the amount of identical complaints, it appears that this "manufacturer" is waiting for an injury or fatality before they do something about it. This fuel hose situation MUST be addressed IMIDIATELY. Please start the recall before it is too late!!!
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.
Car has 51,000 miles, no check engine light or any other warning light.driving in on the freeway at 70 mph when I hear a pop sound and my car loses power, I pushed on the gas and it started to shake violently and I panicked as the construction on the freeway was not allowing drivers a shoulder to pull over on. I was lucky enough to be driving at 2am and with the construction going on, drivers were already slowing down. My car also started blowing a thick white smoke through the back exhaust that could have made it harder to see that late night as it was already foggy here in California. At first I didn-??t realize I was smoking through the back until my car began smelling like burnt oil. I wasn-??t able to get off the freeway until the next exit all while thinking that my car was going to explode from the smell of the burning oil. When I pulled over and got out of the car I made sure I didn-??t see any fire and then I waited to let it cool down, opened the hood and saw oil everywhere. I had it towed to Mercedes and I got the problem and the estimated cost to repair it. The problem turned out being a cracked piston in cylinder one, when it cracked it allowed oil to mix with the gasoline and that-??s what was causing all the white smoke out the rear, the burnt smell was from the oil that was leaked all over my engine getting too hot from the engine. I found out a few days ago that Mercedes-?? has a technical billeting regarding a faulty wrist pin that was causing the pistons to eventually crack. In the bulletin the faulty pin problem is fixed by replacing all the pistons and adding a upgraded pin and many other parts. So there are many other drivers that are experiencing this and driving with faulty wrist pins. Prior to all this happening the car always made a tap tap tap sound from engine and Mercedes-?? said it was normal for 4cylinder turbos to make this sound, sounded like a diesel. But it turned out being from the loose wrist pin. Mercedes lied to us. THE CONSUMER REQUESTED THAT MERCEDES BENZ VEHICLE
Constant fuel smell coming from the engine, you can see gas coming out of the high pressure line. When I park in the garage the whole house smells like gas. Even while driving gas smell coming through the vents constantly
Hi so i woke up this morning and my started my car as usual then noticed the smell of gas all around the car Inside and out. I got worried turned off the car and started sniffing around to see if i can find where the leak was and found out the high pressure fuel pump was leaking i looked up info on this part and it is very common on these car for that part to fail. Im very upset that there is no recall yet when the dealership told me that they do 2-3 of those jobs a week (HIGH PRESSURE FUEL PUMP REPAIRS) and still no recalls on this, what is it going to take to get one", my car has to blow up to get your guys attention?? Oh wait other Mercedes c300 cars in the united states already caught on fire please fix this saftey hazard i want to feel safe and not worry about catching on fire. ITS BEEN 6 years AND STILL HAVE NO RECALLS FOR THIS CAR ??"
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.
Suspension parts are rusting out fast I don't live in a salted road for black ice type of environment car only has 66K miles and ac pours fuel odors in the cabin interior materials are bubbling up fast even after uv treatments.
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
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.
Gas leak in fuel line, while receiving an oil change from a licensed mechanic, he brought to my attention that, there was fuel leaking from the fuel line and showed (fuel line soaked with gasoline directly under the engine), I also noticed that when using the ac the strong smell of gasoline comes through the vents.
This car left me stranded on the side of the road. The car was on working fine driving along then all of a sudden pushing the gas pedal did nothing and the car would not move. The engine shut off completely. The engine was not getting gas. The electrical and everything else was on in the car except the engine. The system in this car has a double fuel tank that only works on one side. The entire fuel system is faulty. The manager at Mercedes told me himself that this is a design flaw in this car. There is no reason why a car with 24,000 miles should have broken down on the side of the road because the entire fuel system does not work. Faulty and horrible workmanship on a supposed luxury vehicle.
