What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 42 complaints with NHTSA since 2015. 16 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 writing to express my concern regarding a series of significant issues I’ve experienced with my vehicle, all occurring within a span of less than six months and well within the 3-year/36,000-mile warranty period.

Common questions
Source: NHTSA, 49 CFR 579.5Is Subaru 15-310-23 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 15-310-23 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 Subaru warranty extension on file lists the ones Subaru has filed.
Which vehicles does 15-310-23 cover?
The manufacturer filed it against 1 model year: 2023 Subaru Solterra. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
