What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 8 complaints with NHTSA since 2015. 5 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.
The infotainment system always reboots. The screen will stay black or frozen. The system is constantly needing to be rebooted by holding the power button until the dodge logo comes up. The back up camera gets stuck when in reverse then going to drive.

Common questions
Source: NHTSA, 49 CFR 579.5Is Dodge 08-380-26 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 08-380-26 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 08-380-26 cover?
The manufacturer filed it against 1 model year: 2025 Dodge Durango. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
