Certain 2017-2018 GMC Sierra HD vehicles may have a condition in which the rear wheel hub nut could become loose due to the rear wheel hub nut retainer not being formed properly.

If the hub nut loosens, the Stabilitrak message may be displayed in the driver information center and the traction control indicator may illuminate. Axle fluid may leak from the axle seal area and rear axle housing damage could occur.

Replace the hub nut retainer. Inspect the axle tube threads for damage and repair as necessary.
