Dodge filed this with NHTSA as a service bulletin dated May 11, 2025, received May 14, 2025, about the electrical system. It names 2 model years (2024–2025). 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 2 model years this bulletin names have filed 63 complaints with NHTSA since 2015. 44 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.
I am reporting an ongoing electrical/charging system problem with my 2024 Dodge Charger Daytona R/T. During August 2026 alone, my vehicle has been taken to the Dodge dealership four times for electrical-related problems, recalls, software updates, and/or repairs.

2025 Dodge Charger · Electrical System · filed with NHTSA Jun 24, 2026 · ODI 11746150
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 Dodge 08-156-25 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 08-156-25 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 08-156-25 cover?
The manufacturer filed it against 2 model years: 2025 Dodge Charger, 2024 Dodge Charger. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
