Ram filed this with NHTSA as a service bulletin dated Oct 16, 2026, received Oct 22, 2026, about the electrical system. It names 14 model years (2025–2027). 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 6 model years this bulletin names have filed 634 complaints with NHTSA since 2015. 340 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 25 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.
Stellantis issued a STAR service order regarding the digital rearview mirror not operating. I bought my truck in April of 2026 and the mirror was inoperable. Ram dealers have had the truck in the shop for over 10 weeks and cannot fix this safety issue. A STAR number and two claims numbers have been assigned.

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 Ram S2608000039 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 S2608000039 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 S2608000039 cover?
The manufacturer filed it against 14 model years: 2026 Ram 1500, 2025 Ram 1500, 2026 Ram 2500, 2025 Ram 2500, 2026 Ram 3500, 2025 Ram 3500 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
