2007 BMW 6 Series

On certain vehicles, the front passenger seat occupant detection mat can fatigue over time.  As a result, the passenger airbag could deactivate, illuminating the airbag warning lamp and the passenger airbag ON/OFF lamp.  Failure of the passenger airbag to deploy during a crash (where deployment is warranted) could increase the risk of personal injury to the seat occupant.  Correction: Vehicles will receive special extended warranty coverage of 10 years from first registration.  Under this special coverage program, vehicles which experience this condition will have the occupant detection mat replaced.

On certain vehicles, the insulated bulkhead connector (used to join the two halves of the positive battery cable) may have been incorrectly installed during vehicle assembly.  Over time, the bolt connection could loosen, which would increase electrical resistance.  In addition, an incorrectly insulated bulkhead connector could allow humidity to accumulate at this location, causing current leakage.  These issues could cause the cable connection to overheat, which could result in a vehicle fire causing property damage and/or personal injury.  Correction: Dealers will inspect and, as necessary, secure the insulated bulkhead connector.  In addition, protective grease will be added to the area and the plastic battery positive terminal cover will be replaced.

On certain vehicles, a check valve in the brake vacuum pump may leak a small amount of lubricating oil.  Over time, this could result in contamination of the brake booster.  Loss of brake power assist could occur which, in conjunction with traffic, road conditions, and driver's reactions, could increase the risk of a crash causing property damage and/or personal injury.  Correction: Dealers will inspect and, if necessary, replace the brake booster and master cylinder.  Additionally, the brake vacuum line (including the check valve) will be replaced to eliminate the possibility of oil reaching the brake booster.

Certain 550I, 650I cabriolet, 650I coupe, and X5 vehicles equipped with a V8 engine, operated in conditions of below-freezing temperatures combined with low humidity, may suffer an electrostatic discharge at the fuel rails.  If this were to occur, the engine's Electronic Control Unit (ECU) could be affected such that engine stalling could result.  If the engine were to stall, this would result in a loss of power steering.  Loss of power steering could lead to a condition in which vehicle handling and control were impaired.  Correction: Dealers will install two additional ground cable between the fuel rails and the ground connection of the ignition coils.

On certain vehicles, the front passenger seat occupant detection system, which is calibrated to detect whether the seat is occupied by a small adult or certain ISOFIX child seats, may misinterpret a properly seated small adult as one of these specific child seats and deactivate the front passenger airbag.  This deactivation would be indicated by the "PASSENGER AIRBAG OFF" lamp being lit.  A deactivated passenger airbag would not deploy during a vehicle crash, leaving the seat occupant susceptible to increased injuries.  Correction: Dealers will replace the front passenger seat occupant detection system.
