Kenworth T680 Recall 20V199: ABS warning light may stay off during power loss, raising crash risk

NHTSA campaign 20V199, reported April 6, 2020, 460,515 vehicles potentially affected.

What this recall means for you

The anti-lock brake system (ABS) controller can lose battery or ignition power. When this happens, the dashboard warning light for the ABS may not come on, so the driver may not know the ABS has stopped working. These vehicles also fail to meet federal air brake and electronic stability control requirements.

If you keep driving without knowing the ABS is not functioning, you face a higher risk of a crash, since the anti-lock braking and stability features may not help you stop or stay in control.

The remedy is free. PACCAR will notify owners, and an authorized dealer will update the NAMUX software in the cab control module at no cost. Contact Kenworth customer service at 1-425-828-5888 or Peterbilt customer service at 1-940-591-4220, and check your vehicle's VIN for open recalls.
