PACCAR is recalling approximately 46 Peterbilt 579 (2022-2023) and Kenworth T680 (2023) vehicles with faulty electronic stability control software that may underestimate vehicle mass, reducing crash prevention performance. Dealers will provide a free software update.

What this means for you

Our assessment, not the agency’s: severity 3/5 (High).

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: Electronic Stability Control is a critical vehicle safety system. This defect could increase crash risk and meets the 'risk-of-harm product' criterion. However, no injuries or deaths have been reported, and the hazard is theoretical, so the maximum score is 3 per the rubric.

Plain-English summary

PACCAR Incorporated is recalling certain 2022 and 2023 Peterbilt 579 trucks and 2023 Kenworth T680 trucks due to a software defect in the battery electric electronic stability control (ESC) program.

The software may incorrectly estimate the vehicle's mass, reducing the performance of the stability control system and increasing the risk of a crash. Affected vehicles do not comply with Federal Motor Vehicle Safety Standard 136 for Electronic Stability Control Systems on Heavy Vehicles.

Owners should contact PACCAR customer service at 1-425-828-5888 (Kenworth) or 1-940-591-4220 (Peterbilt) to arrange a free software update. You can also reach the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 or visit www.nhtsa.gov for more information.
