Paccar bulletin E330
Paccar filed this with NHTSA as a emissions communication dated Jun 13, 2026, received Nov 5, 2025, about the power train — 2 documents under this number. It names 10 model years (2017–2021). 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.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationIn an MX Engine is replaced, a TCS365 case must be opened to get a replacement engine emissions compliance label and expert level rights for resetting and programming the engine control module.

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 Paccar E330 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 E330 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 E330 cover?
The manufacturer filed it against 10 model years: 2017 Paccar MX-11, 2018 Paccar MX-11, 2019 Paccar MX-11, 2020 Paccar MX-11, 2021 Paccar MX-11, 2017 Paccar MX-13 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
