Air bags: side/window
- What is wrong
- BMW of North America, LLC (BMW) is recalling certain 2014-2015 2 Series Coupe (228i, 228i xDrive, M235i), 3 Series Sedan (320i, 320i xDrive, 328i, 328i xDrive, 335i, 335i xDrive, M3, 328d, 328d xDrive), 4 Series Coupe (428i, 428i xDrive, 435i, 435i xDrive, M4), and 2015 4 Series Gran Coupe (428i, 428i xDrive, 435i, 435i xDrive) vehicles. The head air bag inflator may fail at the weld joint, which can cause gas to leak from the inflator or result in an inflator rupture.
- Risk
- An inflator that ruptures may cause sharp metal fragments to enter or exit the vehicle, increasing the risk of injury. Additionally, an inflator that leaks gas may only partially inflate during a crash, increasing the risk of injury.
- Remedy
- Dealers will replace the head air bags, free of charge. Owner notification letters were mailed November 4, 2024. Owners may contact BMW customer service at 1‑800‑525‑7417.

What 2015 BMW M3 owners say
Most recent owner complaints, unedited.
Gas tank has a significant leak. This allows for the opportunity to ignite the car putting all persons lives in danger, and effects emissions. Problem has been confirmed by independent Indy shop technician
Rear view camera stopped working, screen displays "no signal". Fuse did not blow.
Crank hub spun timing sprocket causing valves to impact piston and catastrophic engine failure. Quoted more than $10k out of pocket to repair. This is caused due to poor crank hub design. Car companies have been using keyed crankhubs for generations but bmw decided to not used a keyed hub.. This is very negligent considering how many of these vehicles have engine failure due to this.
