A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 27 model years this bulletin names have filed 1,045 complaints with NHTSA since 2015. 6 of them name Forward Collision Avoidance — 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.
Vehicle stops unexpectedly in parking lots (5-10mph) and on freeways (70-76mph). Speed ranges from 5 - 75 mph. Unexpected braking occurs for no reason. There are typically no obstructions or vehicles in front of the vehicle. It is most concerning when the vehicle automatically applies braking traveling at 70-76mph

Common questions
Source: NHTSA, 49 CFR 579.5Is Cadillac PIC6123G 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 PIC6123G 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 GM warranty extension on file lists the ones GM has filed.
Which vehicles does PIC6123G cover?
The manufacturer filed it against 27 model years: 2019 Cadillac ATS, 2018 Cadillac ATS, 2017 Cadillac ATS, 2016 Cadillac ATS, 2020 Cadillac CT6, 2019 Cadillac CT6 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
