Paccar has recalled nearly 3,900 medium- and heavy-duty trucks with diesel powertrains for a steering issue that could cause a loss of control.

The tie rod or drag link assembly may contain a tie rod or drag link with a ball stud out of hardness specification. An out of hardness specification ball stud may fracture. If this happens, the driver may experience a loss of steering and reduced vehicle control, which may increase the risk of a crash.

About 18% of the recalled trucks are estimated to have the defect. Owners are advised not to drive recalled vehicles until the remedy has been completed. No warning signs have been identified prior to failure.

As of June 6, 2024, Paccar had received no warranty claims or reports about trucks in the field that may be related. Zero reports of deaths or injuries have been received.
