Kenworth service campaign 26PACB
Kenworth filed this with NHTSA as a service campaign dated Jul 2, 2026, received Jul 20, 2026, about the electrical system. It names 4 model years (2024–2026). A service campaign 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 communication"(KW): Certain Kenworth K270 and K370 Battery Electric Vehicle (BEV) chassis equipped with certain DANA cradle harnesses may intermittently lose electrical continuity at one or more C40 connector pins. This can occur without warning and cause loss of propulsion, increasing the risk of a crash. Certified BEV technicians will inspect the C40 connector and replace the cradle harness, if necessary. This safety recall defect is identical to 25KWD and applies to certain Canadian chassis added on 07/02/2026.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kenworth 26PACB a recall?
No. A service campaign 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 26PACB repair free?
A service campaign 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 26PACB cover?
The manufacturer filed it against 4 model years: 2024 Kenworth K270, 2026 Kenworth K270, 2024 Kenworth K370, 2026 Kenworth K370. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
