According to the statement from GM, the problem, "affects the vehicles' two-stage airbag system by reversing the deployment sequence and disrupting the deployment timing of the driver airbag stages." That means in an accident the bag may not work correctly.
Most of the affected trucks are still on the assembly line, in transit or unsold at dealers, says GM. Until a way to repair the problem is found, customer deliveries are stopped. However, "a small number" of them are in the possession of buyers. GM is contacting these people by phone and by FedEx letter to have the vehicles returned to dealers. In the meantime, they'll be given a loaner to drive.
There are no known crashes, injuries or fatalities caused by this airbag problem. Scroll down to read GM's statement on the stop-delivery, which spokesperson Alan Adler said, "reflects what is known at this time."
General Motors has told dealers to halt deliveries of 2015 Chevrolet Colorado and GMC Canyon midsize pickup trucks. These vehicles contain driver airbag connections that were wired incorrectly during the manufacturing process. This condition affects the vehicles' two-stage airbag system by reversing the deployment sequence and disrupting the deployment timing of the driver airbag stages. This condition will cause the driver airbags to not function as designed.
The majority of affected vehicles are being held at the assembly plant or are in transit or unsold at dealerships. GM is working to validate the correction for the condition. Once that service procedure is released to dealers, customer deliveries can resume. A small number of vehicles have been sold.
Customers are being sent a FedEx letter and being contacted by phone to bring their vehicles to dealers as soon as possible. The repair will be done at no change and free loaner vehicles will be available. A safety recall will be conducted but population and other details are not known at this time. GM is aware of no crashes, injuries or fatalities related to this condition.
