General Motors has announced the recall of about 4,000 Chevrolet Malibu vehicles from the 2013 model year. After hard braking, the sensing and diagnostic module (SDM) might reset itself, resulting in unintended roof rail airbag deployment.
The recall affects vehicles made from October 24, 2011 through March 31, 2012. If the reset occurs after hard braking, the system may incorrectly detect that the a vehicle rollover is imminent during an aggressive turn, causing the airbags to deploy. Additionally, the airbags and / or belt pretensioners may not properly deploy during a severe crash.
Dealers will reprogram the SDM at no charge. The recall is expected to begin on June 1, 2012.
