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?

Owner report 11611640 · 2024-08-29 (August 29, 2024)
The fuel tank was leaking a substantial amount of fuel. Yes it is. Our safety was put at risk due to the fuel leak. Any small spark, overheating or if somebody threw a cigarette butt out of their window could have ignited our car. BMW informed me to immediately cease driving the car and bring to the dealership right away. Problem was confirmed by dealership as stated on the attached invoice. No, no warning or indicator lights were present.

17V507000 · Seat Belts:Front
Reported: 2017-08-16 (August 16, 2017)
BMW of North America, LLC (BMW) is recalling certain 2018 430i, 430i xDrive, 440i, 440i xDrive, and M4 convertible vehicles. The Emergency Locking Retractors (ELR) within the front seat belt assemblies may have been produced with incompatible vehicle-sensitive locking mechanism housings.
Consequence: If the vehicle has an incompatible vehicle-sensitive locking mechanism, the seat belt may not restrain the seat occupant in the event of a crash, increasing the risk of injury.
Remedy: BMW will notify owners, and dealers will inspect and, if necessary replace, the front seat belt assemblies, free of charge. The recall began October 13, 2017. Owners may contact BMW customer service at 1-800-525-7417.
