What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 366 complaints with NHTSA since 2015. 117 of them name Engine, Exterior Lighting — 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.
Upon engine start up at the home of my S/O, , the warning "Service Automatic Throttle Control" appeared on the dashboard. Placing the vehicle into gear first in reverse, then in drive resulted in sudden acceleration and erratic lurching. I had no brakes whatsoever. At one point my S/O nearly hit on the dash per signed affidavit.

The Forward Collison icon is on, on my dash. I get a screen message the service is not working, then another to say the signal is lost. I cannot reprogram/reconnect the service in Uconnect. Makes no difference for icon whether engine is running or not. This started in November 2023. The dealer is saying sensor needs replaced.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jeep 0900623 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 0900623 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 0900623 cover?
The manufacturer filed it against 9 model years: 2024 Jeep Compass, 2023 Jeep Compass, 2022 Jeep Compass, 2023 Jeep Renegade, 2022 Jeep Renegade, 2022 Jeep Commander and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
