BMW of North America has issued a recall for 91 model year 2011 BMW 528i, 528xi, 535i, 535xi, 550i and 550xi vehicles manufactured March 1, 2010, through August 31, 2011.
The vehicles may have received a replacement Sensor Cluster Unit (SCU) during a service visit with an acceleration sensor that may have been incorrectly programmed. As a result, the SCU may not accurately determine if activation and deployment of the airbags, safety belt pre-tensioners and head restraints is necessary in the event of a crash.
Depending on the severity of the crash, inadequate activation of the driver and/or passenger airbags, safety belt pre-tensioners and active head restraints may increase the risk of injury.
BMW will notify owners, and dealers will replace the SCU, free of charge. The recall is expected to begin in December 2016.
Owners may contact BMW customer service at 1-800-525-7417.
