Kenworth bulletin 43-087
Kenworth filed this with NHTSA as a emissions communication dated May 5, 2026, received May 6, 2026, about the unknown or other — 3 documents under this number. It names 31 model years (2022–2026). A 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kenworth 43-087 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 43-087 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 43-087 cover?
The manufacturer filed it against 31 model years: 2022 Kenworth T680, 2023 Kenworth T680, 2024 Kenworth T680, 2025 Kenworth T680, 2026 Kenworth T680, 2022 Kenworth T800 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
