Jeep filed this with NHTSA as a service bulletin dated Aug 2, 2023, received Oct 2, 2023, about the back over prevention. It names 7 model years (2021–2023). 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 7 model years this bulletin names have filed 2,042 complaints with NHTSA since 2015. 928 of them name Electrical System, Suspension — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2023 Jeep Grand Cherokee, the 32 owners who gave an odometer reading for Electrical System reported it at a median of 18,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Coinciding with the switch to Italian language, cluster and radio display settings revert back to default settings, auto door locks and paddle shifter becomes inoperative (with no menu to enable)…

However, on **August 31, 2025 — just 13 days later — the exact same coil spring detached again, this time while I was driving at freeway speeds.

Started with the cold weather in December. I got a notification that I need to service the Power Steering system. Lasted for two drives and then went away. Approximately two weeks later, while driving my family in town, the power steering light came on again. Came to a stop at a stop sign and the car put itself in Park.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jeep S2302000004 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 S2302000004 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. Every Stellantis warranty extension on file lists the ones Stellantis has filed.
Which vehicles does S2302000004 cover?
The manufacturer filed it against 7 model years: 2023 Jeep Grand Cherokee, 2022 Jeep Grand Cherokee, 2021 Jeep Grand Cherokee, 2023 Jeep Grand Wagoneer, 2022 Jeep Grand Wagoneer, 2023 Jeep Wagoneer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
