What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 601 complaints with NHTSA since 2015. 363 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.
I own a 2023 Jeep Grand Cherokee. On August 18, 2025, the rear suspension coil detached and fell off in my driveway. I had the vehicle repaired at an authorized Jeep dealership. 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.

Generally, for the entire time we've owned the car, it has ongoing and systemic electronics malfunctions. This ranges from the car slamming on its own brakes while driving to systems not working to the seat shifting on its own while driving to false positives in the NAV system, etc.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jeep 0815923 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 0815923 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 0815923 cover?
The manufacturer filed it against 1 model year: 2023 Jeep Grand Cherokee. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
