NHTSA Defect Investigations for the 2006 BMW 550

The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 2006 BMW 550, both ongoing and closed, are listed below:

  1. INVESTIGATION: BMW AIRBAG LIGHT ILLUMINATION

    NHTSA Engineering Analysis #EA08001

    Component(s): Air Bags
    Air Bags:Frontal
    Air Bags:Frontal:Sensor/Control Module

    Summary: BMW is conducting a safety recall campaign on approximately 200,000 MY04 through MY06 subject vehicles built through 11/30/05 to correct the front passenger seat air bag occupant detection mat. The specific vehicles included in the recall aremy04- 06/ 5-series with standard and sport seats, MY04-06/ X3-series and MY06/ 3-series with sport seats. In addition, BMW will extend the warranty coverage of the passenger seat air bag occupant detection mat to 10-year/unlimited mileage on approximately 120,000 remaining MY04-06 subject vehicles built through 11/30/05. The specific vehicles included in the extended warranty are my 06/ 6 series, my 06/ 3-series with standard seats, MY04-05/ Z4, MY04-06/ 7 series, my 06/ X5, and MY04-06/ 5-series with comfort seats.the average frequency of failures among the extended warranty groups was less than 1/7th of the recall vehicle groups.please see BMW's 08V-384 recall notification for further detailsdepending on seat configuration and vehicle geometry, the occupant detection mat can fatigue during use depending on the manner and frequency of the front passenger's entry and exit.specifically, over time, micro-cracks could develop in the side flanks of the mat causing a broken circuit.a brokencircuit can lead to the deactivation of the passenger air bag and the illumination of both the air bag warning light and the passenger air bag light.

    Summary: In certain MY 2005 through MY 2006 BMW vehicles, the occupant classification system (OCS) for the passenger frontal airbag may malfunction and render the passenger airbag inoperative.in June 2006, BMW issued a technical service bulletin (si B 72 02 06) regarding the illumination of the airbag warning light and the passenger airbag status lamp.illumination of these lights warn that an open electrical circuit may be present within the passenger seat mat sensor.when both of the lights are illuminated, the passenger frontal air bag will not deploy in a frontal crash.certain BMW vehicles in addition to the subject vehicles contain the same seat mat sensor.these are the MY 2004 5-series, 7-series and X3, the MY 2004 through 2006Z-4 series and MY 2006 3-series, 6-series and X5 vehicles.an improved seat mat sensor was introduced in December 2005 for the mid-MY 2006 production.in response to ODI's information request letter, BMW provided 1,172 owner reports and 28,238 warranty claims.initial review of the data indicate that 280 non-duplicating owner reports and 13,051 non-duplicating warranty claims may be related the subject defect issue on the subject vehiclesthis preliminary evaluation is being upgraded to an engineering analysis (EA08-001).
