Lisle, IL – December 11, 2022 – Navistar, which owns the International brand, and General Motors, the owner of the Chevrolet brand, are recalling thousands of vehicles because parts of their suspension and steering mechanisms may break apart. This would lead to a loss of vehicle stability, increasing the risk of a crash and injury. The Chevrolet vehicles in question were manufactured by Navistar.

In total, Navistar is recalling 31,467 buses and trucks, including the following models:

Recall summary  

Parts of suspension and steering of the recalled vehicles were made with nuts that were not properly heat-treated when made due to a supplier error. Heat-treating these components is an essential part of the manufacturing process to ensure they can withstand the test of time and hold the vehicles’ joints together.

Because of the error, these nuts – called Navistar hex flange lock nuts – may break. This can lead to the “loss of tension” in both steering and suspension and make the vehicle unstable, difficult to control and hard or impossible to steer.

Recall risks

The defect significantly ups the risk of a crash and injury. No injuries or warranty claims have been reported by either manufacturer.

Warning signs 

Should one or more affected nuts fall apart, the driver could notice the steering and overall vehicle handling become less sharp and responsive. 

Safety tips 

If you notice a “loose feeling” when driving, pull off the road to the nearest safe location. If you cannot identify any obvious causes, such as, for instance, a flat tire, get the vehicle towed.
