Dodge filed this with NHTSA as a service bulletin dated Jul 3, 2026, received Jul 8, 2026, about the electrical system. It names 1 model year (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 1 model year this bulletin names have filed 13 complaints with NHTSA since 2015. 2 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.
"Service Shifter" alert came on at about 2250 miles and engine light came on about 100 miles later . Dodge service at dealership looked at and could not determine issues, lights did not illuminate in their care. Picked up my car after service and both service shifter and engine lights came back on

Common questions
Source: NHTSA, 49 CFR 579.5Is Dodge 08-265-26 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 08-265-26 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.
Which vehicles does 08-265-26 cover?
The manufacturer filed it against 1 model year: 2026 Dodge Durango. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built on or before 20 Jul 2026 — the build date is on the certification label in the driver’s door jamb.
