GM has issued a product safety recall, number N232414720, for certain units of the 2024 Chevy Silverado HD that were produced with a steering gear shaft containing a supplier manufacturing defect that could cause the shaft to fracture during use.
The problem: the potentially defective steering gear shaft used in a small number of 2024 Chevy Silverado HD trucks could fracture at the point where it connects to the steering arm (also known as the pitman arm), causing the steering gear shaft and the steering arm to become disconnected from one another.
The hazards: if the steering gear shaft fractures and connection with the steering arm is lost, it will no longer be possible for the driver of the affected 2024 Chevy Silverado HD to steer the vehicle. This could result in a crash or accident, with possible consequences including damage to the Silverado HD and/or other vehicles, and the potential for injuries or fatalities.
The fix: the fix for affected 2024 Chevy Silverado HD trucks is to replace the steering gear shaft and any associated parts that are damaged or defective, such as the steering gear pinion shaft / pitman arm nut. This repair is carried out free of charge to customers.
Before the repair can be applied, GM instructs dealerships to inspect potentially affected Silverado HD trucks, since only a small percentage of units actually require steering gear shaft replacement. Dealers are further instructed to use the GM Global Warranty Management System to check the Investigate Vehicle History screen, verifying the unit’s involvement if it is marked “Incomplete Remedy Not Available” before beginning work.
Note: The General has instructed dealers to inspect all 2024 Silverado HD units in their inventory and apply the repair as needed. It is a violation of federal law to sell, trade to other dealerships, or use for demonstration purposes any potentially affected Silverado HD unit before correct inspection and application of the fix, if required.
If the vehicle passes inspection with no repair required, the dealership must correctly enter it in the system as “Inspect Only – Vehicle Passed Inspection (No Further Action Required),” labor code 9106931, before selling, trading, or demonstrating it.
Affected components: steering gear shaft.
