RENTON, WA — Paccar has initiated a safety recall involving more than 1,000 Kenworth and Peterbilt trucks due to a manufacturing defect in the accelerator pedal assembly that could cause the throttle to stick. The recall, tracked by the National Highway Traffic Safety Administration, impacts specific model year 2023 and 2024 trucks that rely on components supplied by Orscheln.
The root of the problem lies in an oversized magnet carrier located within the throttle pedal assembly. This part acts as a pivot point, and its incorrect dimensions can cause the pedal to bind or fail to return to the idle position when a driver lifts their foot. Paccar engineers traced the defect back to a molding tool issue at the supplier level, which has since triggered a wider equipment recall affecting thousands of units across multiple manufacturing brands, including Oshkosh.
Affected units include the 2024 Kenworth T180, T280, T380, and T480, as well as Peterbilt models 535, 536, 537, and 548. While braking remains effective in overriding the stuck pedal, the inherent risk of unintended acceleration or a failure to reach idle is a serious concern for any CDL-A driver operating these vehicles on public roads. Fluid contamination near the assembly can further degrade the pedal's performance, potentially worsening the binding issue.
What This Means for Drivers
Owner-operators and fleet managers currently running these specific medium-duty models should check their VINs immediately against the official Paccar list. If you notice any hesitation or resistance when releasing the fuel pedal, contact your local dealership to schedule a replacement. Reliable vehicle performance is a non-negotiable standard for those holding CDL-A driver positions, and operating a vehicle with a known throttle defect creates an unnecessary safety liability. Many trucking companies hiring today are prioritizing fleet maintenance audits to ensure these recalled pedals are swapped out before they lead to a roadside breakdown or accident.
Industry Reaction
Equipment failures of this nature highlight the reliance of major OEMs on third-party suppliers like Orscheln. When a single molding tool error ripples through the supply chain, it forces thousands of professional drivers into the shop for unscheduled downtime. Maintaining strict adherence to FMCSA regulations requires that carriers act quickly on these safety bulletins to protect their drivers and the public. As the industry continues to evolve, the pressure remains on manufacturers to tighten quality control protocols to prevent these types of mechanical failures from reaching the highways.
Key Points
- The recall affects over 1,000 Kenworth and Peterbilt trucks from the 2023 and 2024 model years.
- A defective, oversized magnet carrier in the throttle pedal is the primary cause of the binding.
- Orscheln, the equipment supplier, is implicated in a broader recall involving over 4,000 pedal units.
- Drivers are advised that while the brakes will stop the truck, the pedal may fail to return to idle, requiring immediate service intervention.
