“General Motors has notified Chevrolet and GMC dealerships to stop the delivery of certain 2021 Chevrolet Silverado HD and GMC Sierra HD pickup trucks,” GM Senior Communications Manager Dan Flores told GM Authority in an emailed statement. “We are investigating a potential quality issue with these vehicles. We have no additional information to share at this time.”
While GM refused to elaborate on the quality issue, a GMC salesperson familiar with the matter told GM Authority the stop-sale order is related to a wire chafing problem that could pose a potential fire hazard.
GM switched to production of the 2022 Chevy Silverado HD and 2022 GMC Sierra HD on July 12th, although a number of 2021 model year trucks remain on dealership lots. So far this stop-sale order applies only to 2021 model year trucks. Production of the Chevy Silverado HD and GMC Sierra HD takes place at the GM Flint Assembly plant in Michigan.
The stop-sale order will be a small setback for GM, as the Silverado HD and Sierra HD are two of its most profitable nameplates. It was already grappling with low inventory levels of its popular pickup models due to the semiconductor chip shortage, which forced it to shut down the Flint Assembly plant for one week in August.
GM has also dealt with staffing shortages at Flint Assembly this year. The automaker held a job fair at the plant in June to help fill 400 vacant positions at the facility, which only resulted in around 200 new hires. A Flint Assembly plant manager later appealed for local job seekers to apply at the Flint plant in an interview with a local news outlet in July.
We’ll provide an update on the stop-sale order as more information becomes available.
