What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationIssue: complaint of rattle from exhaust Before replacement: Check for loose exhaust Aluminum isolator brackets (check if the bracket is movable by hand/bolts not fully fastened to the vehicle). If loose, tighten and check to see if the rattle is still present. Check clearances between exhaust components and Aluminum isolator brackets, as well as other parts of the vehicle. If physical metal-to-metal contact is identified, loosen the clamps joining the catalytic-side and muffler-side systems and slide the muffler side exhaust back until the 4 small M&M sized bulges can be seen on the driver-side cat-side pipes. Take care not to damage the system, do not use a hammer to break the muffler side free. The muffler side exhaust should be pushed towards the front of the vehicle until the rim of the muffler side inlet pipe meets the edge of the bulges. Re-tighten and check for rattles again. If the rattle is still present, replace the system.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jeep 9100781 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 9100781 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 9100781 cover?
The manufacturer filed it against 3 model years: 2026 Jeep Grand Cherokee, 2025 Jeep Grand Cherokee, 2024 Jeep Grand Cherokee. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
