Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationQudra Lift Reman Compressor Excessive Repairs on Quadra Lift Reman Compressors Part Numbers: 68041137AF / R8572790AA / 68087233AA / 52124932AE / 52124934AE / 68064343AC Purpose The Star Parts Catalog has been updated to support component-level repair of the Quadra-Lift air suspension system. Replace only the component confirmed failed through diagnostics. Avoid replacing the complete assembly when an individual service component can correct the concern. Available Service Components Part Number Description R8572790AA Air Suspension Compressor 68087233AA Air Suspension Valve Block 52124932AE Front Air Suspension Hose Assembly 52124934AE Rear Air Suspension Hose Assembly 68064343AC Air Suspension Reservoir 68087240AA Temperature Sensor 68041137AF Compressor Assembly Diagnostic Decision Tree Customer Complaint: Service Air Suspension Message / Sagging / Unable to Adjust Ride Height / Compressor Running Continuously. Step 1: Retrieve and record all DTCs. C15D9 (Low Air Mass): Perform air mass test, complete system fill, leak-down test, and leak source identification before compressor replacement. C15A1 (Unable to Obtain Desired Ride Height): Verify ride height, perform leak-down test, inspect valve block, air lines, and air springs. C1562-98 (Over Temperature): Inspect for excessive compressor run time, leaks, low air mass, and restrictions before condemning the compressor. If a leak is found, repair the leak and verify operation before replacing the compressor. If no leak is found, perform compressor functional evaluation. If moisture is in the lines and valve block, then evacuate or replace lines. Only replace the compressor when a defect is verified (internal leak, failed solenoid, weak output, seized motor, failed functional test, or electrical failure). Service Component Selection Guide Verified Root Cause Recommended Repair Compressor Internal Failure Replace Compressor Valve Block Failure Replace Valve Block Air Line Leak Replace Air Line Air Spring Leak Replace Air Spring Temperature Sensor Failure Replace Temperature Sensor Technician Reminder Replace only the component confirmed failed through diagnostics. In many cases, compressor replacement is not required when the root cause is an air leak, valve block issue, airline concern, or sensor fault.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jeep 9100897Rev1 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 9100897Rev1 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 9100897Rev1 cover?
The manufacturer filed it against 7 model years: 2022 Jeep Grand Cherokee, 2021 Jeep Grand Cherokee, 2020 Jeep Grand Cherokee, 2019 Jeep Grand Cherokee, 2018 Jeep Grand Cherokee, 2017 Jeep Grand Cherokee and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
