Kenworth T440 Tractors Recalled for Missing Air Brake Valve

PACCAR is recalling 2011-2012 Kenworth T440 tractors because a required quick release air valve may be missing, potentially delaying brake release and increasing crash risk.

What this means for you

Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The recall involves a structural vehicle defect in the air brake system that increases the risk of a crash, which aligns with the rubric criteria for a Severe (4) rating.

Plain-English summary

PACCAR Incorporated is recalling certain model year 2011-2012 Kenworth T440 tractors manufactured between October 18, 2010, and February 9, 2011. The recall addresses a failure to comply with Federal Motor Vehicle Safety Standard No. 121, "Air Brake Systems." Specifically, the quick release air valve required in the full truck service brake air line gladhand connection may not have been installed.

The omission of this valve may allow the full truck service brake air line gladhand release timing to exceed the threshold of 0.75 seconds by 1/10th of a second. This delay in the service brake of a towed vehicle or trailer increases the risk of a crash.

Kenworth dealers will install the quick release air valve in the full truck service brake air line with the gladhand connection. The source states that all of the vehicles have been repaired, and therefore, an owner notification letter will not be issued for this campaign. The recall began on June 23, 2011. Owners may contact PACCAR at 1-425-468-7400 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
