Kenworth bulletin 24KWE / 24PBE
What it saysThe parts section has been updated for clarity. NHTSA’s full summary ↓
Kenworth filed this with NHTSA as an emissions communication dated Jan 31, 2026, received Jan 6, 2026, about the electrical system — 2 documents under this number: 24KWE/24PBE and 1 more. It names 37 model years (2021–2026). An emissions communication is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
The parts section has been updated for clarity. The right-hand shift stalk may have an improper wire harness terminal crimp within the wire harness connector. Loss of communication between the right-hand shift stalk and the vehicle may result in the vehicle being disabled after it comes to a stop, thereby increasing the risk of crash or injury. A warning will appear on the dash display when communication is lost, including transmission or engine warnings, “!” next to DNR/DNRP indicator, “-“ in the DNR/DNRP indicator, and/or chimes, depending upon whether you are operating a diesel/gas or battery electric vehicle.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

None of these model years has a page on this site (it covers EPA-certified cars, trucks and SUVs from 2016), so the bulletin is listed here on its own.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kenworth 24KWE / 24PBE a recall?
No. A emissions communication is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls.
Is the 24KWE / 24PBE repair free?
A emissions communication is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 24KWE / 24PBE cover?
The manufacturer filed it against 37 model years: 2021 Kenworth T180, 2022 Kenworth T180, 2023 Kenworth T180, 2024 Kenworth T180, 2025 Kenworth T180, 2021 Kenworth T280 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built 7 Dec 2020 – 23 Dec 2022; built 9 Nov 2020 – 23 Dec 2022 — the build date is on the certification label in the driver’s door jamb.
