Recall 21V401 affects 4,511 1999-2001 BMW 3 Series vehicles for a NADI driver air bag inflator defect. Repair is free at any franchised BMW dealer.
BMW is recalling 4,511 1999-2001 3 Series vehicles, including 330CI and 323I models, because Takata NADI driver air bag inflators were inspected but not replaced under earlier recalls. During deployment, the inflator can explode and send metal fragments into occupants, or the air bag can underinflate; BMW dealers will replace the driver air bag module free of charge.

What's wrong?
The driver air bag in the 1999-2001 BMW models listed for this recall uses a Takata Non-Azide Driver inflator. The inflator is the metal canister inside the steering-wheel air bag that fills the air bag cushion when crash sensors command deployment. It has to build pressure quickly, but in a controlled way, so the cushion opens between the driver and the steering wheel.
On affected vehicles, the driver-side inflator was inspected under earlier BMW recalls but was left in place. BMW reports that a manufacturing issue allows the inflator to absorb moisture. Testing found leakage and reduced deployment performance in some returned inflators, and the investigation points to manufacturing variation, climate, vibration, and vehicle-specific factors as contributors. In a crash, the inflator can explode or leave the air bag cushion underinflated.
There is no warning sign before failure. The air bag warning light is not a reliable advance signal for this specific inflator problem, so the VIN decides whether the driver air bag needs replacement.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific car is included.
What's the safety risk?
An inflator explosion during air bag deployment can send metal fragments into the driver or passengers. An underinflated air bag also does not protect the occupant as designed. Both risks increase the chance of serious injury or death. There is no warning sign before the inflator fails. Schedule the inflator replacement soon. Repair is free at any franchised BMW dealer.
What should I do?
- Check your VIN to confirm your 1999-2001 BMW 330CI, 3 Series, 328CI, 330I, 330XI, 328I, 323I, 325CI, or 323CI is included in this recall.
- Contact a franchised BMW dealer to schedule the free driver-side air bag inflator replacement that fixes the Takata NADI inflator issue.
- Bring the owner letter if you have it. If not, reference recall number 21V401 when you call.
- Call BMW customer service at 1-800-525-7417 with questions before your appointment.
- Avoid unnecessary trips until the driver-side air bag inflator is replaced.
What happens at the repair
