Chrysler filed this with NHTSA as a service bulletin dated Jan 5, 2024, received Mar 18, 2024, about the power train. It names 7 model years (2017–2023). 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 7 model years this bulletin names have filed 4,205 complaints with NHTSA since 2015. 2,450 of them name Electrical System, Power Train — 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 2017 Chrysler Pacifica, the 301 owners who gave an odometer reading for Power Train reported it at a median of 27,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Was driving the vehicle and all of a sudden the vehicle lost ability to accelerate. Warning of "Service Charging System" appears on the dash and the "D" indicator starts blinking. Warning of "Shift to P to Start" appears and check engine light comes on. I tried to shift to park and restart the vehicle, but it did not do anything.
2020 Chrysler Pacifica · Power Train · filed with NHTSA Jan 6, 2023
The car totally shut off when driving 20 MPH. Full tank of gas. Brand new car with 5,000 miles on it. Called Chrysler -- they left US abandoned mid-road, they said it would take the 90 minutes. We purchased the top, perpetual warranty. Called aaa who got the car onto a flatbed. But no way to get it off because wheels are locked.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Chrysler 2100124 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 2100124 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 2100124 cover?
The manufacturer filed it against 7 model years: 2023 Chrysler Pacifica, 2022 Chrysler Pacifica, 2021 Chrysler Pacifica, 2020 Chrysler Pacifica, 2019 Chrysler Pacifica, 2018 Chrysler Pacifica and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
