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 5 model years this bulletin names have filed 1,597 complaints with NHTSA since 2015. 950 of them name Electrical System, Forward Collision Avoidance — 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.
On April 20, 2026, my 2025 Jeep Grand Cherokee L was involved in a crash due to a sudden and complete brake failure. At the time of the incident, the vehicle was in the custody of an authorized FCA dealership. An employee of the dealership was operating the vehicle when the brakes completely failed to respond, resulting in an accident.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jeep S238A000038 REV. D 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 S238A000038 REV. D 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 S238A000038 REV. D cover?
The manufacturer filed it against 5 model years: 2026 Jeep Grand Cherokee, 2025 Jeep Grand Cherokee, 2024 Jeep Grand Cherokee, 2023 Jeep Grand Cherokee, 2022 Jeep Grand Cherokee. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
