Quote the number at a service desk; it is what the dealer’s system is keyed on.

Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 1,039 complaints with NHTSA since 2015. 359 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Chrysler 08-170-26 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 08-170-26 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 08-170-26 cover?
The manufacturer filed it against 8 model years: 2024 Chrysler Pacifica, 2023 Chrysler Pacifica, 2022 Chrysler Pacifica, 2021 Chrysler Pacifica, 2024 Chrysler Voyager, 2023 Chrysler Voyager and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
