What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 234 complaints with NHTSA since 2015. 66 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.
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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Stellantis 0815623 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 0815623 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 0815623 cover?
The manufacturer filed it against 2 model years across 2 brands (Dodge and Chrysler): 2023 Chrysler Pacifica, 2023 Dodge Durango. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
