Brake Application and Release Timing/FMVSS 121

NHTSA #13V573000 · Service Brakes · NHTSA notice

Reported November 18, 2013 · PACCAR Incorporated

Potentially affected: 18 vehicles

Repair completion: 5.56% (latest rate the manufacturer reported to NHTSA; dataset updated November 3, 2026)

Manufacturer campaign 13KWL · Owners notified January 15, 2014 · Vehicles built March 22, 2006 – July 15, 2013 (per NHTSA)

Defect description

PACCAR is recalling certain model year 2007-2014 Kenworth T800 and W900 trucks manufactured March 22, 2006, through July 15, 2013 and equipped with Primaax tridem rear suspensions and a pusher and/or tag axle. The affected trucks have brake chambers that take longer to apply or release the brakes than the required time limit. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."

Safety consequence

Brakes that take longer to apply may lengthen the distance needed to stop the truck, increasing the risk of a crash.

Manufacturer remedy

Potentially affected: 65 vehicles

Manufacturer campaign 07KW2 · Owners notified May 21, 2007 · Vehicles built May 23, 2005 – January 14, 2007 (per NHTSA)

Defect description

TILT/TELESCOPING STEERING COLUMN/TRW

NHTSA #06V447000 · Steering — Column · NHTSA notice

Reported November 24, 2006 · PACCAR INCORPORATED

Potentially affected: 443 vehicles

Manufacturer campaign 06KW2 · Owners notified December 22, 2006 · Vehicles built June 6, 2006 – November 9, 2006 (per NHTSA)

Defect description

ON CERTAIN TRUCKS EQUIPPED WITH A TRW TILT/TELESCOPING STEERING COLUMN, THE TILT LOCKING MECHANISM ON THE STEERING COLUMN MAY DISENGAGE. THIS COULD PREVENT THE STEERING COLUMN FROM LOCKING IN TO PREDETERMINED POSITIONS.

Safety consequence

SHOULD THE LOCKING MECHANISM DISENGAGE, THE TILTING TRAVEL OF THE COLUMN WOULD BE UNRESTRICTED.
