The defect
PACCAR Incorporated (PACCAR) is recalling certain 2022-2023 Peterbilt 579 and 2023 Kenworth T680 vehicles. Incorrect software in the battery electric heavy duty electronic stability control program may underestimate the mass of the vehicle. As such, these vehicles may fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 136, "Electronic Stability Control Systems on Heavy Vehicles."
The risk
An incorrect estimate of the vehicle mass can reduce the performance of the stability control system and increase the risk of a crash.
