How many Paccar trucks are affected by the PDC recall?

Paccar is recalling 5,919 model-year 2027 trucks built this summer for a power distribution center defect that may trigger false ABS warnings or electrical failures. The company estimates fewer than 1 percent of the recalled units actually carry the defect. Dealers will inspect PDC serial numbers and replace contaminated boxes at no cost to owners.

The problem originated at supplier PKC Group North America. A damaged air compressor filter allowed oil to leak into the soldering process for printed circuit boards during manufacture. The contamination affects the PDC, the central electrical hub that routes power to chassis systems.

What symptoms will drivers see?

The only warning most drivers will notice is an ABS malfunction lamp on the dash. The contaminated solder joints may fail intermittently or completely, cutting power to antilock brake controllers or other chassis modules fed by the PDC. No reports of crashes or injuries have surfaced in the recall filing.

The recall covers trucks built during a narrow production window this summer, when the contaminated boards were installed. Paccar has not disclosed which assembly plants or which models (Kenworth, Peterbilt, or DAF) are in scope, but the 5,919 unit count suggests multiple lines were affected.

What dealers will do

Service departments will pull the PDC serial number from each recalled truck and cross-check it against Paccar's defect list. Units with contaminated boards get a new PDC installed under warranty. The swap takes roughly two hours in most shops, including electrical system checkout afterward.

Owners with trucks in the field should watch for the ABS lamp and schedule the inspection as soon as the dealer calls. A failed PDC can disable more than just ABS. Depending on the truck's electrical architecture, lighting circuits, engine sensors, and transmission controllers may also drop offline if solder joints open under vibration.

How this compares to other recent electrical recalls

Paccar's PDC issue joins a string of electrical and fastener recalls this year. Mack and Volvo issued a do-not-drive recall in June for wheel-retention hardware on 446 Granite, Anthem, Pinnacle, and Pioneer units, a mechanical failure with immediate crash risk. The PDC defect is less urgent but still grounds a truck if the board fails completely.

Supplier quality lapses are the common thread. PKC Group's contaminated solder process mirrors the root cause in other component recalls, where a single manufacturing step goes out of spec and contaminates an entire production batch. The low estimated defect rate (under 1 percent) suggests Paccar caught the problem quickly and isolated the affected serial number range.

What this costs fleets

The recall is free to owners. Paccar covers parts and labor under the factory warranty. Downtime is the real cost. A two-hour PDC swap during a scheduled PM is manageable. A roadside failure 800 miles from the home shop means tow fees, hotel costs, and a load that misses its delivery window.

Fleets with multiple 2027 units should pull VINs from the recall notice and batch the inspections during the next service cycle. Waiting for the ABS lamp to light is a gamble. A contaminated PDC may work fine for months, then fail without warning when a solder joint cracks under thermal cycling or road vibration.

When to expect the recall notice

Paccar has not announced a formal recall start date in the source material. Owners should contact their Kenworth or Peterbilt dealer with the truck VIN to confirm whether the unit is in scope. Dealers have access to the PDC serial number database and can schedule the inspection immediately.

The 5,919 unit count is large enough to strain dealer service capacity in some markets. Fleets that run multiple 2027 trucks may face a wait for appointment slots, especially if the recall notice hits during peak service season. Prioritize trucks with the highest annual miles or those running time-sensitive freight.
