Kenworth T680 Recall 15V458: Hazard lights may stop flashing after braking

NHTSA campaign 15V458, reported July 22, 2015, 12,551 vehicles potentially affected.

What this recall means for you

On certain Kenworth T440, T470, T660, T680 and T880 trucks, the daytime running lights do not switch off when the hazard warning lights are on. After the brake pedal has been pushed for more than two seconds, the daytime running lights override the hazard flashing, so the hazard lights may not flash. Normal hazard flashing returns once the brake pedal is released.

If the hazard warning lights are overridden, drivers of oncoming vehicles may not be warned of the stopped or slowed truck, which raises the risk of a crash.

Owners can contact Kenworth customer service at 1-425-828-5000 about this recall. The repair is free: an authorized dealer will update the cab controller software. Check your vehicle's VIN for open recalls to confirm whether your truck is affected.
