EXTERIOR LIGHTING 19V452000 2019-06-14 343 affected
Defect

PACCAR Incorporated (PACCAR) is recalling certain 1990-2020 Peterbilt 320 and 520 vehicles built with specific amber rear turn signals. The turn signals may also light up with the stop/tail lights when the brakes are applied. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle…

Consequence

Rear Turn signals that illuminate at the same time as the brake lights may create confusion and impair the effectiveness of the brake lights, increasing the risk of a crash.

Remedy

PACCAR will notify owners, and for trucks with rear amber lights, dealers will add a jumper harness between the chassis electrical harness and amber tail lights, free of charge. The recall began August 1, 2019. Owners may contact PACCAR customer service at 1-940-591-4220. PACCAR's number for this recall is 19PBC.
