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 1 model year this bulletin names have filed 487 complaints with NHTSA since 2015. 260 of them name Electrical System, Steering — 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 2021 Jeep Grand Cherokee, the 19 owners who gave an odometer reading for Steering reported it at a median of 25,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
May 16,2025 my power steering light came on. I checked the fluid, and when I turned it back on it was gone. The next day, I started driving all my safety lights in dash & mirrors came on. When I pulled into my kids school it made a strange noise. I then drove right across the street to Lees tires.

My vehicle was experiencing the exact same HVAC/AC issues described in Customer Satisfaction Notification Z33 for the 2021 Jeep Grand Cherokee L. Although the campaign specifically lists my make, model, and year, Stellantis claims my VIN is not covered.

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 S2123000070 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 S2123000070 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 S2123000070 REV. A cover?
The manufacturer filed it against 1 model year: 2021 Jeep Grand Cherokee. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
