1 recall across 1 model year
The GMC TopKick 4500 has 1 recall affecting the 2003 model year, where the rear axle anchor plate on trucks equipped with an 11,000-lb. rear axle can fracture, allowing the axle to shift forward or backward and feed unexpected steering inputs to the driver, raising the risk of a crash.
When the anchor plate breaks, the rear axle is no longer held in place, so hard braking, cornering, or rebound over a bump can cause the axle to move and pull the vehicle in an unintended direction with little warning.
