The recall includes a stop-sale of about 3,000 new 2014-'15 trucks still on dealer lots until the repair is made.
This is part of a global recall of 1,037,982 GM trucks in Canada, Mexico, Latin America and the Middle East.
"The flexible steel cable that connects the seatbelt to the vehicle can fatigue and separate over time as a result of the driver repeatedly bending the cable when entering the seat," GM said in a statement provided to Edmunds.
No crashes, injuries or fatalities have been linked to the recall. The problem was discovered through warranty data.
Chevrolet dealers and GMC dealers will enlarge the side shield opening, install a pusher bracket on the tensioner, and if necessary, replace the tensioner assembly. A date has not been specified for the recall.
No information about the recall has been posted on the website of the National Highway Traffic Safety Administration, which oversees vehicle safety in the U.S.
Edmunds says: If you own one of the affected trucks, you should expect to receive an official recall notice within 60 days, according to federal regulations. If you have an immediate concern, contact your dealer now.
