My wife and I purchased this vehicle at a certified used dealership. We fueled it up and drove it around that night and parked it at our home. The next morning it smelled terribly of gasoline so I looked under the car. The driver's side of the fuel tank was crushed in and it was pouring gasoline all over the driveway. Their was a puddle approximately 3 feet wide under the car. I had it towed to the dealer and they were shocked. We both assumed that they never filled the talk so the problem wasn't known. They replaced the tank free of charge and once again I filled the tank and drove it around for the weekend. I noticed the gasoline smell again and looked under the car and was shocked to see the tank crushed in again and the fuel leaking out. I ran a google search on this and found out that I was not alone. There is a known problem with a purge line that causes the talk to implode on itself. I am very surprised to not find a recall on this. I would think that avoiding a car fire would be a concern for the NHTSA. I hope with enough complaints they force a recall.

Hi, I am not sure if this is a safety defect or not. I had a sound like an expanding and contracting of metal in the back underneath of car. It sounded like a cookie sheet when it is first heating up in the oven and it expands and contracts. The dealer couldn't find anything when I brought it in but said that they were going to call BMW technical support because they had a theory that a spider was clogging up the fuel line and that this had happened once before to their knowledge and resulted in the gas tank collapsing. I brought car in again and they said they removed a spider and put in a new pipe/line. The sound I had heard before was gone. Some people have told me, however, that the whole system is a closed system and that this couldn't have happened. Is it possible" is problem fixed"
