Seat Belts · Jun 23, 2015

NHTSA campaign 15V399000 · 47,042 vehicles

Problem
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.
Fix
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.
Electrical System › Ignition · Sep 9, 2014

NHTSA campaign 14V540000 · 47,043 vehicles

Problem
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.
Fix
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.
