PACCAR Incorporated: Electronic Stability Control (esc)
PACCAR Incorporated reported this defect to federal regulators on Jan 16, 2023 and put the number of vehicles at risk at 46. The repair is free for as long as the recall stands.
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.
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.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 23V007000.
