Trucking news and briefs for Tuesday, March 5, 2024:

Paccar has issued a new recall that affects approximately 697 Kenworth trucks of varying models and vintages, according to National Highway Traffic Safety Administration documents.

In the affected trucks, the air tanks have an insufficient volume of air for the brake system, and as such, they fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems." Insufficient air volume can reduce braking performance and increase the risk of a crash, the recall states.

Truck models included in the recall are:

Dealers will install the correct volume air tanks, free of charge. Owner notification letters are expected to be mailed April 23. Owners may contact Paccar customer service at 1-425-828-5888 with recall number 24KWD. NHTSA’s recall number is 24V-145.

The same air tank issue also prompted a recall from Mack Trucks of approximately 10 model year 2022-’24 Mack Granite trucks.

Mack dealers will add additional air tank volume, free of charge. Owner notification letters are expected to be mailed April 15. Owners may contact Mack customer service at 1-800-866-1177 with recall number SC0458. NHTSA’s recall number is 24V-122.
