Paccar is recalling close to 6,000 Kenworth and Peterbilt trucks for a potential problem that could cause a loss of engine power, ABS (antilock brake) functions, exterior lighting, windshield wipers and defogging.

The power distribution center (PDC) box may be contaminated with oil in these vehicles.

The problem happened when a damaged air compressor filter caused an oil leak into the soldering process of the printed circuit boards during manufacture by the supplier, PKC Group North America.

The only indication drivers may get is an ABS malfunction warning lamp.

The recall affects 5,919 2027 trucks, although less than 1% are estimated to have the defect. Dealers will inspect the PDC serial numbers and replace the PDC boxes as necessary, free of charge.
