Western Star 47X Recall 24V668: Brake lights may not light during automatic braking

NHTSA campaign 24V668, reported September 10, 2024, 16,890 vehicles potentially affected.

What this recall means for you

Certain heavy trucks may have a software problem in which the brake lights do not illuminate when the automatic emergency braking system applies the brakes on its own. This can happen on vehicles that have an upfitted body lighting interface controller and replacement brake lights.

If the brake lights stay dark during an automatic braking event, drivers behind you may not realize you are slowing down, which increases the risk of a rear-end crash.

The repair is free. Authorized dealers will update the automatic brake assist software at no cost to you. Owner notification letters were mailed October 24, 2024. You can contact Daimler Trucks North America customer service at 800-745-8000 and reference recall F1009, and you should check your vehicle's VIN for any open recalls.
