GM halts shipments of new mid-sized pickup trucks

General Motors (GM) told dealers Friday to halt shipments of new mid-sized pickup trucks over air bag issues.

The Detroit-based automaker has notified dealers to stop deliveries of the 2015 Chevrolet Colorado and GMC Canyon until the problem is fixed.

Some of the airbag connections were wired incorrectly during the manufacturing, causing the vehicles' two-stage airbag system to reverse the deployment sequence and disrupt deployment timing, GM said in a statement.

Only a small number of the trucks have been sold, GM said, and the majority are being held. Dow Jones reported that the recall covers almost 524,000 cars in North America, adding to Thursday's separate recall of roughly 118,000 vehicles.

Customers will receive a FedEx letter and a phone call instructing them to bring their vehicles to dealers as soon as possible to obtain free repairs and loaner vehicles, the statement said.

GM said it is not aware of any crashes, injuries or fatalities related to the air bag issue.
