What it saysField Service Campaign for DEF Regen Inhibit Dash Switch Indicator NHTSA’s full summary ↓
Daimler Truck filed this with NHTSA as a service campaign dated May 23, 2025, received Jun 4, 2025, about the engine — 3 documents under this number: SF716-OWN LTR, SF716-DLR LTR, SF716-Bulletin. It names 7 model years across Freightliner and Western Star (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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Daimler Truck SF716 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 SF716 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 SF716 cover?
The manufacturer filed it against 7 model years across 2 brands (Freightliner and Western Star): 2025 Freightliner 108SD, 2026 Freightliner 114SD, 2025 Freightliner Business Class M2, 2025 Freightliner Cascadia, 2025 Western Star 47X, 2024 Western Star 49X and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
