Mack service campaign S5075 202609

What it saysFleet Improvement Campaign - Work Brake Valve Replacement NHTSA’s full summary ↓

Mack filed this with NHTSA as a service campaign dated Sep 2, 2026, received Oct 2, 2026, about the service brakes. It names 2 model years (2026–2027). 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.

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.

Also filed against: 2026 Mack LR; 2027 Mack LR.

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.
