## What is wrong

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."


## What can happen

An incorrect estimate of the vehicle mass can reduce the performance of the stability control system and increase the risk of a crash.


## The remedy

Dealers will update the software, free of charge.  Owner notification letters are expected to be mailed March 17, 2023.  Owners may contact PACCAR's customer service at 1\-425\-828\-5888 \(Kenworth\) and 1\-940\-591\-4220 \(Peterbilt\).  PACCAR's numbers for this recall are 23PBA and 23KWA.


## Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1\-888\-327\-4236 \(TTY 1\-800\-424\-9153\), or go to www.nhtsa.gov.
