What it saysActive Damping Control Module (ADCM) Stored Diagnostic Trouble Codes (DTCs). NHTSA’s full summary ↓
Stellantis filed this with NHTSA as a service bulletin dated May 1, 2026, received May 6, 2026, about the electrical system. It names 6 model years across Ram and Dodge (2024–2026). 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 6 model years this bulletin names have filed 594 complaints with NHTSA since 2015. 307 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 2025 Ram 1500, the 24 owners who gave an odometer reading for Electrical System reported it at a median of 6,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I am filing a safety defect complaint regarding a 2026 Dodge Charger Daytona (400V electric vehicle platform) that suffered a catastrophic high-voltage system shutdown at approximately 1,261 miles. The vehicle had charge remaining and was being prepared for charging when it experienced a forced EV system shutdown and would not restart.

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 Stellantis S2623000031 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 S2623000031 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 S2623000031 cover?
The manufacturer filed it against 6 model years across 2 brands (Ram and Dodge): 2026 Dodge Charger, 2025 Dodge Charger, 2024 Dodge Charger, 2026 Ram 1500, 2025 Ram 1500, 2024 Ram 1500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
