What it saysFor FCCC Ambient Air Temperature Sensor NHTSA’s full summary ↓
Fccc filed this with NHTSA as an emissions communication dated Jul 10, 2024, received Aug 2, 2024, about the engine — 3 documents under this number: FL998-OWN LTR, FL998-DLR LTR, FL998-Bulletin. It names 2 model years (2022). An 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.

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 Fccc FL998 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 FL998 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 FL998 cover?
The manufacturer filed it against 2 model years: 2022 Fccc MT45, 2022 Fccc MT55. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built on or after 3 Mar 2021 — the build date is on the certification label in the driver’s door jamb.
