Freightliner Cascadia trucks have been recalled by Daimler Trucks North America- DTNA because of inadequately tightened drag link taper joint.
Notably, if the joint becomes loose, it can cause a complete loss of steering control since the drag link will get separated from the steering arm.
This recall will affect 105,183 trucks which include the 2019 Freightliner Classic Cascadia trucks that have been manufactured at the company’s plant in Santiago, Mexico from April 2018 to December 2018 and at Saltillo, Mexico between April 2018 to July 2020.
As per the defection report rolled out by DTNA, around 1% of the potentially involved trucks may have the defect.
It is well to be noted that the drivers may notice wandering noises, vibrations, and loose steering in the affected vehicles.
As per the remedy, DTNA will inspect the taper joint and repair it wherever necessary.
From April to June 2020, one of the fleets reported losing steering control in five trucks, and another fleet reported that the drag link completely got separated from the steering arm in two trucks.
An investigation by DTNA led to the implementation of management of torque and a tool audit in all plants.
Besides, two more customers reported losing the steering due to the taper joint connection in February this year.
After a deeper investigation was launched, the same issue cropped up in seven more instances where complete separation was reported. After two more separations occurred, DTNA decided on a safety recall of all the trucks on August 30.
