Freightliner Cascadia Recall 18V491: Dash Warning Lights May Not Check Brake Warnings

NHTSA campaign 18V491, reported July 20, 2018, 43,584 vehicles potentially affected.

What this recall means for you

On certain 2017-2019 Freightliner Cascadia trucks, the instrument cluster may skip the startup bulb check for the anti-lock brake (ABS) and electronic stability control (ESC) warning lights if the ignition is switched off and back on too quickly. Without that check, the driver may not know the warning bulbs are burned out or not working.

That matters because if the ABS or ESC system malfunctions, the warning light may not alert the driver, which increases the risk of a crash. The problem also means these trucks do not fully meet federal standards FMVSS 121 (air brake systems) and FMVSS 136 (electronic stability control on heavy vehicles).

The fix is free at an authorized Freightliner dealer, which will reprogram the instrument cluster so a bulb check runs every time the ignition is turned on. Some trucks with tire pressure monitoring systems will also need replacement parts at no cost. Owners can contact Daimler Trucks North America customer service at 1-800-547-0712, referencing recall FL-780, and should check their VIN for open recalls.
