03V421000 · Air Bags:Frontal:Sensor/Control Module-Inactive
Reported: 2003-10-24 (October 24, 2003)
ON CERTAIN PASSENGER VEHICLES, A MICROPROCESSOR IN THE AIR BAG CONTROL MODULE, WHICH ACTIVATES THE FRONT AIR BAGS, THE SIDE AIR BAGS, THE FRONT SEAT SAFETY BELT PRETENSIONERS, AND THE BATTERY SAFETY TERMINAL, MAY HAVE A MALFUNCTION THAT COULD LEAD TO AN UNINTENDED ACTIVATION OF ONE OR MORE OF THESE COMPONENTS.
Consequence: UNEXPECTED DEPLOYMENT OF THE AIR BAG(S) COULD CAUSE SERIOUS INJURY IF AN OCCUPANT IS TOO CLOSE TO THE DEPLOYING AIR BAG(S). IN ADDITION, THE BATTERY SAFETY TERMINAL MAY ALSO BE ACTIVATED. IF THAT HAPPENS, THE STARTER CABLE WOULD BECOME DISCONNECTED FROM THE BATTERY, AND THE ENGINE COULD NOT BE RESTARTED.
Remedy: DEALERS WILL REPLACE THE AIR BAG CONTROL MODULE. OWNER NOTIFICATION BEGAN NOVEMBER10, 2003. OWNERS SHOULD CONTACT BMW AT 1-800-831-1117.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
2000: 0 complaints · 2001: 0 complaints
| Model year | Through age 0 | Through age 1 | Through age 2 |
|---|---|---|---|
| 2000 | 0 | 0 | 0 |
| 2001 | 0 | 0 | 0 |
Date coverage across each selected cohort
| Year | Incident dates used | Filing date fallbacks | Excluded dates |
|---|---|---|---|
| 2000 | 2 | 0 | 0 |
| 2001 | 0 | 0 | 0 |
Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
