NHTSA Complaint #11610911 — 2018 BMW M4

What component or system failed or malfunctioned, and is it available for inspection upon request? Fuel Tank on my BMW under 50k miles started leaking after a fill up. How was your safety or the safety of others put at risk? I didn't notice any leaks at the gas station but once I got home, pulled in my garage I noticed the smell of fuel, figured I just spilled a bit. I left my car to go get ready, once I came back the garage was filled with gas fumes. I looked under the car and saw a decently large puddle under the driver side. I live in Texas where it was quite warm that day. I could've easily caught fire and cause harm to myself and so many others. Has the problem been reproduced or confirmed by a dealer or independent service center? I had it towed immediately the next day to a BMW dealership, and they stated the seams of the fuel tank are leaking. How is that possible, that's a manufacturing issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Only the BMW dealership, they won't have anyone else look at it. Slapped me with a $3,489 repair estimate, and that's it. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were literally no lamps, alerts, lights or indicator to tell me something was wrong. The car could've exploded on me. I still have the federal emissions warranty active and they are saying it doesn't cover a fuel tank.
