Jeep bulletin S1721000016
Jeep filed this with NHTSA as a service bulletin dated Dec 19, 2025, received Jul 27, 2020, about the power train — 4 documents under this number: S1721000016 REV. B. It names 33 model years (2016–2023). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

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 Jeep S1721000016 a recall?
No. A service bulletin 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, or on its page here.
Is the S1721000016 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does S1721000016 cover?
The manufacturer filed it against 33 model years: 2023 Jeep Cherokee, 2022 Jeep Cherokee, 2021 Jeep Cherokee, 2020 Jeep Cherokee, 2019 Jeep Cherokee, 2018 Jeep Cherokee and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
