Kenworth incorrect software in the battery electric heavy duty electronic stability control program may underestimate the mass of the vehicle.
The short version
PACCAR Incorporated reported a problem with the electronic stability control (esc). Here is what owners need to know.
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."
An incorrect estimate of the vehicle mass can reduce the performance of the stability control system and increase the risk of a crash.
Take it to a dealer — they will update the software, free of charge.
