Other Fuel System Tank Assembly problems of the 2014 BMW 328

Fuel tank leaks gasoline. An alarming amount of fuel leaks and this is an issue that seams common among BMW f30 chasis. In my case when my car is ful tank it starts dripping fuel, visible. The problem seems to be a seal that is made to flex but with time that seal fails and creates a fire hazard due to high volatile fumes and liquid gas leakage. I was able to notice as I parked my car when arriving home due to the strong smell of fuel. -the issue is reproducible. -on the safety side, it puts a risk of fire. -the vehicle unfortunately has not been inspected by police or insurance -there is an error code un the computer of the vehicle that has to do with detection of fuel leakage.

I got a cel and dropped it off at the dealer. They said it was to the active scr tank. After research I found out a lot of BMW vehicles have the item fail. The 328d is not on the list of extended warranties. Are there many 328d's that fail?.

Def tanks froze in cold weather causing multiple parts to fail in the engine. Def system I believe is now compromised as a result of poor engineering for the overall system. Vehicle is parked outside and there were temperatures well below zero.

My BMW 328i x-drive giving "drivetrain malfunction" message when the car was running on sport mode or eco mode. After few minutes of driving the cars shuts down. This had happened 3 times before in same month and every time the dealership looked at it the replaced a part(fuel injector and module in fuel tank) no help and happened again next day they did it. After I topped up the fuel with 2 gallons when this happen this time the message is not should no more and the car started running normal gain. BMW is not able to figure out the issue and I will be turning it in tomorrow again for diagnosis. The issue is still un-know.

On interstate 10, during the accelaration, the engine completely lost its power. I had to immediately pull over before I lost the momentum. The CA highway patrol pushed me to a safe place. The vehicle was towed to the dealer and the dealer replaced the entire fuel tank. The second incident was almost 20 days after again during the acceleration on freeway at the speed of 70, the engine lost its power in a way that the car did not proceed for a while. The dealer advised that it was nothing wrong with engine because they could not read any error in the system and ii had to wait till I recive an aerror on the lcd. I notified them that it is a serious problem specifically on the freeway becasue losss of power can cause an accident, but to no avail.
