GM is instructing dealers to ensure that any vehicle subject to this service update that enters vehicles inventory or is dropped off for service, and is still covered under the New Vehicle Limited Warranty, must receive the service update correction before it is sold or released. Any vehicle that is subject to this service update must be inspected and repaired prior to customers taking possession of the vehicle.
