Extremely Urgent Safety Warning! Similar to the the passenger fuel filter extended warranty on the passenger side, the driver's side plastic fuel filter pump is obviously visably defective and forming a large crack, thereby leaking a significant amount gasoline into the back seat, with much also draining out the bottom of the vehicle. Additionally, the metal studs securing the filter are painted, making removal of the filter difficult without breaking the studs. No warning lamps or messages.

Mold in a/c
Due to the same defect Mercedes issued a recall for on the 2011 GLK, the fuel and sender pumps cracked due to a product defect causing gasoline to leak out of the vehicle as well as into the vehicle. The leak is near the exhaust causing a high degree of risk for car fire. Online research reveals numerous 2010 GLK owners with the same issue at various points in the life of the vehicle.
When my child was riding in the same car with me, my car suddenly died due to all fuel leaked out. Our car ran out of gas because all fuel were leaked. We can smell gas inside the cabin. Initially I thought car died because we ran out of the gas. After receiving 2 gallon gasoline from the tow truck, we saw dripping gasoline from the bottom of the car when the car engine is on. I am glad it did not happen to me on the highway or there was no fire sparkles near by. My car is only 110K miles with no accident record. I do not expect a car has a defective hazard like this. People could be killed. We took the car to the dealership. Fuel Pump Assembly 221-470-17-90-28 and Fuel Filter Unit221-470-17-90-28 will be replaced. Benz has recalled 2011 model. I have news below, " The specific models are the 2011-2012 C300, GLK350, E350, S400 Hybrid, S550, S63 AMG, CL550 and CL63 AMG, but only those built from April 18, 2011, through July 12, 2011. Mercedes says there are some 5,800 vehicles affected by the latest recall in the U.S. the unit may crack when operated in high temperatures. This may cause fuel to leak, which could then cause a fire." My question is, why my 2010 model was not recalled? They were using same parts. If my car's parts has the defect, which caused "fuel to leak, which could then cause a fi re." for just under 110K miles, why the federal safety agency does not do anything to prevent this happen? If you search "Fuel leaking benz" , you will see tons of consumer complains. I could have ended up die if I was not lucky. Fuel pump is a critical part, it should not drip gasoline. Can you force Benz to take action before people died?

Two fuel tank leaks that are a fire hazard. First one was around fuel pump, cracks in plastic flange. Had repaired with a sealant. Recently another leak around the filler tube. Leak around passenger side rear wheel when filling tank. Strong smell of gasoline if not completely filled to cause leak. I would think a dangerous fire hazard. I see recalls for other year models, but not 2010, even though basically identical.
String gas smell from under the car, found the fuel pump cover cracked and seal faulty
Lately, everytime I filled up the gas tank, I can smell gas from the rear left area. After some time when the tank is maybe a little over half the smell is gone. I assume there is a leak somewhere from the fill pipe to the tank. Maybe a bad rubber connector, gasket/seal failure? The vehicle has never been involved in any crash. Normal usage. Low mileage. Should this be covered by MB warranty at no cost to the owner? Thank you.
Plastic seal on gaskets for gas tank failed on both sides of car. Causes leaking of fuel and odor into passenger area of vehicle and danger of explosion due to leaking fuel. It occurs when gas tank is more than 3/4 full to full of fuel.
