Chrysler filed this with NHTSA as a service bulletin dated Jul 15, 2023, received Sep 25, 2023, about the electrical system. It names 6 model years (2021–2023). 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 database

Owners of the 6 model years this bulletin names have filed 965 complaints with NHTSA since 2015. 337 of them name Electrical System — 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 2021 Chrysler Pacifica, the 16 owners who gave an odometer reading for Electrical System reported it at a median of 30,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Keys were inside car with only an infant inside and the doors were locked with no other key fob anywhere nearby. There must have been an issue with the car’s safety system to unlock the car in this situation. There was no 3 beeps that would unlock the car. Car was parked in Walmart parking lot in the heat.

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 579.5

Is Chrysler 0817523 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 0817523 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 0817523 cover?

The manufacturer filed it against 6 model years: 2023 Chrysler Pacifica, 2022 Chrysler Pacifica, 2021 Chrysler Pacifica, 2023 Chrysler Voyager, 2022 Chrysler Voyager, 2021 Chrysler Voyager. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
