Trucking news and briefs for Monday, Dec. 13, 2021:
Just more than 900 model year 2019-2022 Kenworth T880 and W990; Peterbilt 567, 579 and 389; and 2022 Peterbilt 536 and 537 wrecker and auto hauler trucks are being recalled by Paccar for an issue affecting the work/winch brake, according to National Highway Traffic Safety Administration documents.
The winch brake in the affected trucks may unintentionally disengage the service brakes during winching operations, causing the trucks to roll.
The cause of the problem is described as: “Slight vehicle movement during winching causes the wheel speed sensor to detect vehicle movement. There is ‘noise’ in the wheel speed sensor at lower vehicle speeds, and erroneous values are communicated. These erroneous values exceed the speed interlock, causing the work brake to disengage.”
Dealers will update the vehicle software for free as a remedy to the issue. Owners may contact Paccar customer service at 425-828-5888 (Kenworth) with recall number 12KWG or 940-591-4220 (Peterbilt) with recall number 21PBM. NHTSA’s recall number is 21V-906.
The U.S. Senate unanimously passed a resolution introduced by Sens. Susan Collins (R-Maine) and Angus King (I-Maine) designating Saturday, December 18th, 2021, as “Wreaths Across America Day.”
