Stellantis filed this with NHTSA as a service bulletin dated Mar 13, 2026, received Jul 23, 2025 — 2 documents under this number: S2523000070 and 1 more. It names 24 model years across Jeep and Ram (2024–2026). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Stellantis S2523000070 REV. A 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 S2523000070 REV. A 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 S2523000070 REV. A cover?
The manufacturer filed it against 24 model years across 2 brands (Jeep and Ram): 2026 Jeep Grand Cherokee, 2025 Jeep Grand Cherokee, 2024 Jeep Grand Cherokee, 2026 Jeep Grand Wagoneer, 2025 Jeep Grand Wagoneer, 2024 Jeep Grand Wagoneer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
