5,919 Kenworth and Peterbilt Trucks Recalled Over a Silent Power-Loss Defect

NHTSA is reporting a recall affecting 5,919 PACCAR trucks — brand-new 2027 Kenworth and Peterbilt models built over a three-week window this summer. The defect is genuinely serious: it can cause a sudden, unannounced loss of drive power, brakes, lights, or wipers, and in most cases the driver gets no warning at all before it happens.

Which Trucks Are Affected

The recall covers specific 2027 model-year trucks built in a narrow window:

Kenworth T480 and T380 — built between June 22 and July 13, 2026
Peterbilt 537, 536, and 548 — built between June 23 and July 13, 2026

What Actually Went Wrong

The problem traces back to a supplier defect. A damaged air compressor filter at PKC Group North America — the manufacturer of the power distribution center (PDC) box — allowed oil to leak into the soldering process during production of the printed circuit boards. That oil contamination in the PDC box can cause real, unpredictable electrical failures once the truck is on the road.

Why this recall is more serious than most: The contamination can cause loss of drive power, loss of Antilock Brake System functionality, loss of exterior lighting, loss of windshield wipers, or loss of the defogging system. Only the ABS malfunction warning lamp gives any indication before a failure — none of the other failure modes come with a warning. A driver could lose lights or wipers in bad weather, or lose drive power in traffic, with zero notice beforehand.

What to Do If Your Truck Might Be Affected

Don't wait for the mail:

Check your build date and model against the affected range above.
Contact your dealer now rather than waiting for the interim notification letter, which wasn't expected to go out until September 25, 2026.
Peterbilt customer service: 1-940-591-4220. Kenworth customer service: 1-425-828-5888. Reference PACCAR recall number 26PACD.
The fix is free — dealers will inspect the PDC serial number and replace the box as necessary at no cost.

The Insurance Angle

A known, documented safety recall is exactly the kind of issue worth addressing immediately rather than treating as a formality to deal with whenever the letter arrives. If an accident happens involving a truck with an unresolved, publicly documented defect, it can complicate how a claim gets handled and raise real questions about liability — especially with a defect this specific and this well-documented. If your truck is in the affected range, getting it inspected now protects you on two fronts: it fixes a genuine safety risk, and it closes off a complication you don't want hanging over a future claim.

Worth checking regardless: If you bought a new Kenworth or Peterbilt this summer and aren't sure whether it falls in the affected build window, it costs nothing to call and check the PDC serial number. This isn't a "wait and see" recall given the failure modes involved.

Frequently Asked Questions

What trucks are affected by the PACCAR recall?

NHTSA is reporting a recall affecting 5,919 PACCAR trucks — specifically 2027 Kenworth T480 and T380 models built between June 22 and July 13, 2026, and Peterbilt 537, 536, and 548 models built between June 23 and July 13, 2026.

What is the actual defect?

The power distribution center (PDC) box may be contaminated with oil, caused by a damaged air compressor filter that allowed oil to leak into the soldering process of the printed circuit boards during manufacturing at supplier PKC Group North America. Oil contamination can cause failures in the electrical system.

What happens if the defect causes a failure while driving?

The contamination could result in loss of drive power, loss of Antilock Brake System functionality, loss of exterior lighting, loss of windshield wipers, or loss of the defogging system. Critically, only the ABS malfunction warning lamp provides any warning — the other failure modes can occur without any indication beforehand.

How do I get my truck fixed?

Dealers will inspect the PDC serial number and replace the power distribution box as necessary, free of charge. Interim notification letters were expected to be mailed to owners starting September 25, 2026, with a second round of letters once the final remedy is confirmed available. Owners can contact Peterbilt customer service at 1-940-591-4220 or Kenworth customer service at 1-425-828-5888, referencing PACCAR recall number 26PACD.

Does this recall affect my insurance if I have an accident before it's fixed?

A known, documented safety recall is exactly the kind of thing to address immediately rather than wait on. If an accident happens involving a known defect that hasn't been remedied, it can complicate a claim and raise real liability questions. Don't wait for the interim letter if your truck matches the affected VIN range — contact your dealer now to check your PDC serial number.
