NHTSA campaign 17V840, reported December 22, 2017, 1,222 vehicles potentially affected.

What this recall means for you

Certain transmission control software in these heavy trucks may let the engine crank briefly even when the shifter is not in neutral, which does not meet federal starter interlock requirements.

If the transmission is not in neutral when the engine starts running, the truck may move unintentionally, increasing the risk of a crash.

PACCAR will notify owners, and authorized dealers will update the transmission control module software free of charge. Owners can contact Peterbilt customer service at 1-940-591-4000 or Kenworth customer service at 1-425-828-5000. Check your VIN for open recalls to confirm whether your truck is affected.
