2010 BMW 528I Fuel system Problems

“My vehicle suddenly stops. I've already replace the sparkplugs, coils, & fuel filter, but the problem does not go away. The sudden stopping happens when I'm driving or when I'm idle at either a stop sign or a light. The vehicle sputters until it completely turns off from I'm idle and there is no warning for when I'm actually driving, it just stops.”

“I have taken this car in specifically for this complaint twice in the last year. I have a severe gas fume smell in my car, in my trunk and around my car. Happens after I have been driving and park and return to the car typically. Sometimes happens when I have been driving and turn off the car. If I park in my garage the garage smells like gas/gas fumes for a lengthy period of time. I have been told that after testing by the dealer that there is no gas leak. The problem continues. Happens regardless of the amount of gas in the tank. …”

“While having my oil changed, I told the mechanic that I smelled a little bit of gasoline when driving and to check it out. I was shown that under the back seat, behind the driver side there is a sending unit and a fuel line that transfers gas from one tank to another. This plastic component has a tip where the fuel line connects. This tip cracked and broke (no idea why), leaking and pooling gasoline inside the car, directly underneath the passenger seat and filling the car with highly combustible fumes. So much so that the mechanic I took this car to, would not let me drive it out of there. …”

“I noticed a smell of fuel each time my wife parked her car inside our garage. Her car for due a service so I took the vehicle in for a full service. The mechanic called and asked if we had been smelling fuel inside or around the vehicle. He then explained that he suspected it was originating from underneath the rear seat. He later contacted me to explain that the plastic tube located on top of the in-tank electric fuel pump assembly had developed a crack and was allowing fuel to spray out on top of the assembly, which was allowing fuel and fumes to build-up in-and-around the vehicle. …”

“While accelerating the car jumps into neutral randomly. Whether from a slow start or accelerating on a highway. It has happened dozens of times and the dealer says there is no fix.”
