What this means for you
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.
