Altec service campaign SIL-3176

Altec filed this with NHTSA as a service campaign dated Nov 7, 2024, about the unknown or other. It names 15 model years (2020–2024). 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

Altec has learned that the main control valve harness connectors can become brittle on the affected units. This can result in the harnesses cracking or breaking, allowing water into the harness and causing loss of function.

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 579.5

Is Altec SIL-3176 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 SIL-3176 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 SIL-3176 cover?

The manufacturer filed it against 15 model years: 2020 Altec AC40, 2021 Altec AC40, 2022 Altec AC40, 2023 Altec AC40, 2024 Altec AC40, 2020 Altec AC45 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
