BMW issued a recall on the 7 SERIES, and 5 SERIES models

On certain vehicles, a Sensor Cluster Unit (SCU) having incorrect programming may have been installed in error by dealers during servicing. As the SCU helps determine if the driver and/or passenger airbags, seat belt pretensioners and active head restraints should be deployed during a crash, incorrect programming could result in an inadequate activation of one or more of these restraint systems in a crash. This could increase the risk of injury to occupants. Correction: Dealers will replace the SCU. Note: In the interim, owners are advised to stop operating their vehicle until the defect has been repaired.
