Kirkland, Washington — Paccar has formally announced a safety recall impacting nearly 6,000 model year 2025 Kenworth and Peterbilt commercial vehicles equipped with Cummins X15 diesel engines. Federal regulators at the National Highway Traffic Safety Administration logged the action under recall number 24V-789, targeting specific fuel pump barrels manufactured with inadequate fatigue strength that can fracture under operational stress.

The campaign covers a wide range of heavy-duty equipment including Kenworth C500, T680, T800, T880, W900, and W990 models, alongside Peterbilt 567, 579, and 589 units. When a fuel pump barrel cracks, it creates a direct fuel leak that can trigger a sudden engine stall, dramatically increasing the risk of a highway collision. Drivers operating these vehicles may notice diminished performance, a dashboard warning light triggered by low fuel pressure, or the distinct sight and smell of diesel fuel pooling under the hood.

This latest manufacturer action stems from a broader component recall initiated by Cummins in September, which flagged over 9,000 X15 powerplants supplied across the commercial vehicle and fire apparatus sectors. Earlier in October, Daimler Truck North America and Navistar launched similar corrective campaigns covering roughly 1,700 trucks. With Paccar now accounting for the bulk of the remaining engines, the vast majority of the units originally flagged by Cummins are tied to active manufacturer remedies.

What This Means for Drivers

For an OTR truck driver or fleet owner-operator running late-model iron, an unexpected engine stall on a heavily traveled interstate creates an immediate safety hazard. Paccar and Cummins are coordinating repairs to replace the defective fuel pump barrels at zero cost to vehicle owners. Fleet maintenance managers and independent operators should monitor their mailboxes for notification letters slated for delivery by December 22, though checking vehicle identification numbers with local dealers remains the fastest way to verify eligibility. CDL-A drivers should immediately report any unusual fuel odors, power loss, or low-pressure warnings to their dispatchers to keep equipment off the road before a complete failure occurs.

Industry Reaction

Engine component manufacturing defects place an unfair burden on independent owner-operators and small fleets already wrestling with tight margins and rising operating costs. Unplanned shop time pulls revenue-generating trucks off the highway and disrupts tight supply chain schedules. While manufacturers are covering the physical parts and labor for the pump barrel replacements, lost downtime remains a significant operational hurdle for drivers working hard to meet delivery windows across the country.

Key Points

• Nearly 6,000 Kenworth and Peterbilt trucks from model year 2025 are impacted by the Paccar recall.
• Defective fuel pump barrels feature low fatigue strength, creating a fracture risk that leads to fuel leaks and sudden engine stalls.
• Paccar dealerships will replace the faulty fuel pump components free of charge, with owner notification letters scheduled to arrive by December 22.
• Drivers can contact Kenworth at 425-828-5888 (recall 24KWH), Peterbilt at 940-591-4220 (recall 24PBH), or Cummins directly at 812-377-5000.
