Seat belts
General Motors LLC (GM) is recalling certain model year 2011-2013 Chevrolet Caprice vehicles manufactured October 15, 2010, to October 22, 2013, and 2008-2009 Pontiac G8 vehicles manufactured July 25, 2007, to February 18, 2009. In the affected vehicles, the flexible steel cables that connect the seat belts to the vehicle at the outside of the driver seat and the front passenger seat may be bent from being sat on while entering the vehicle. This repeated bending may result in the cable breaking.
Risk: If the cable breaks, the seat occupant may not be properly restrained in the event of a crash, increasing their risk of injury.
Remedy: GM will notify owners, and dealers will replace the seat belt tensioner assembly which includes the steel cable, free of charge. These replacement parts reposition the tensioner cable out of the path of entry into the vehicle and uses a more flexible cable, set at a more upright angle. The recall began on July 5, 2016. Owners may contact Chevrolet customer service at 1-800-222-1020 or Pontiac customer service at 1-800-762-2737. GM's number for this recall is 15206.

General Motors LLC (GM) is recalling certain model year 2011-2013 Chevrolet Caprice vehicles manufactured October 15, 2010, to December 6, 2013, and 2008-2009 Pontiac G8 vehicles manufactured July 25, 2007, to February 18, 2009. In the affected vehicles, the driver may accidentally hit the ignition key with their knee, unintentionally knocking the key out of the run position, turning off the engine.
Risk: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position could cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
Remedy: GM will notify owners, and dealers will remove the key blade from the original flip key/RKE transmitter assemblies, and cut and fit a revised key blade and housing assembly, in which the blade has been indexed by 90 degrees, to the original RKE transmitter assembly. GM issued an interim notification to owners on December 31, 2014. The recall began on February 4, 2015. Owners may contact Chevrolet customer service at 1-800-222-1020 and Pontiac customer service at 1-800-762-2737. GM's number for this recall is 14445. Note: Until the recall has been performed, it is very important that drivers adjust their seat and steering column to allow clearance between their knee and the ignition key.

Air bags:frontal:sensor/control module-inactive
General motors (gm) is recalling certain model year 2008-2009 pontiac g8 vehicles manufactured from november 2, 2007 through january 22, 2009. A 5th percentile female anthropomorphic test device (atd) in a 30 mph frontal barrier test exceeded the head injury criteria (hic) requirements of the standard. With the front passenger seat positioned full forward, the seat position sensor will cause a 30 milliseconds deployment delay between the first and second stages of the dual-stage frontal passenger air bag.
Risk: In the event of a crash, this delay may result in increased head injury to certain front seat occupants.
Remedy: Gm dealers will reprogram the sensing and diagnostic module free of charge. The safety recall began on november 30, 2011. Owners may contact pontiac at 1-800-620-7668.
