Problem: 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.
Risk: 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.
Fix: 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.

Fuel/propulsion system
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.

Fuel/propulsion system
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…

Fuel/propulsion system
Fuel tank was leaking. I brought it in to BMW of San Antonio who found the left side top area of fuel tank leaking fuel from the sealed portion. Heat caused the top of fuel tank to expand and crack. BMW of SA required me to buy a replacement fuel tank. When I said, if I buy the replacement fuel tank, won't this issue keep reoccurring every time it gets hot. The tech advised that BMW was aware of the problem and designed the replacement fuel tanks differently, so that the fuel tanks won't expand and crack in the same manner. I advised BMW of North America requesting they pay for the replacement, that this should have been a recall issue due to the dangers of this problem (other BMW vehicles…

Fuel/propulsion system
I think the fuel tank has cracked on the upper portion of the tank. I noticed a smell of gas on my way home from filling gas and when I got home I realized there was a puddle of gas sitting underneath my car. I jacked up the car and inspected the underneath and saw nothing, I noticed the gas was leaking from a higher spot, somewhere I couldnt see. Ive read on forums that its happened before to a few other people and someone personal that I know. Yes the car can be inspected upon request. Safety is put at risk because the gar is leaving right next to the exhaust, which can easily catch fire to the car, myself, and other drivers on the road. I was getting a misfire on my car and realized the…
