14520a - special coverage (revised to include 2007, and 2010-2013 model year chevrolet silverado and gmc sierra light duty trucks, along with expanding coverage to certain u.s. States). Some 2008-2009 model year chevrolet silverado and gmc sierra light-duty vehicles registered in canada or 2007, and 2010-2013 model year chevrolet silverado and gmc sierra light duty vehicles registered in or previously registered in maine, new hampshire, new york, and vermont or in the canadian provinces new brunswick, newfoundland, nova scotia, prince edward island, ontario, and quebec may develop a fractured middle-leaf spring in the three-leaf rear-suspension spring assembly, forward or rearward of the joint to the rear axle. This condition may result in noise, ride-height difference, contact with a rear tire, and/or damage to other components under the vehicle. Vehicles with this condition will have reduced load-carrying capacity. If the condition occurs within the term limits, dealers will replace the rear springs.

Owners of these vehicles have filed 141 complaints in the suspension category.
