What owners reported
Source: NHTSA complaint databaseOwners of the 40 model years this bulletin names have filed 1,148 complaints with NHTSA since 2015. 260 of them name Electrical System, Structure — 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 2020 BMW X5, the 16 owners who gave an odometer reading for Electrical System reported it at a median of 60,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B660325 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 B660325 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 BMW warranty extension on file lists the ones BMW has filed.
Which vehicles does B660325 cover?
The manufacturer filed it against 41 model years: 2025 BMW 5 Series, 2024 BMW 5 Series, 2023 BMW 5 Series, 2022 BMW 5 Series, 2021 BMW 5 Series, 2020 BMW 5 Series and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
