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 ???.
I took my car in for a multi point inspection at the end of November 2019 to mercedes of bellevue. I begun smelling gasoline from the inside cabin of my car a few days after the service and had to take the car back to the dealership. They found that fuel hoses going to the high pressure fuel pump to be leaking fuel. With this being a potential fire hazard and a safety issue, I argued with the dealer that it should be covered under warranty, which I still had a cpo warranty from purchasing the vehicle from this specific dealership. I did some research online and found that, this is a very common issue with my vehicle model, 2015 Mercedes Benz C300. I am unsure why this issue is not yet recalled by the manufacturer or why the dealership did not honor this issue tto be covered under warranty. . As a concerned customer of the hazardous possibilities a fuel leak could cause, I still moved forward with paying for the repair out of pocket versus continuing to debate with the finance and service personnel that it should be covered under warranty that I still had at the time.
