What owners reported
Source: NHTSA complaint databaseOwners of the 22 model years this bulletin names have filed 447 complaints with NHTSA since 2015. 132 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 2021 BMW X5, the 13 owners who gave an odometer reading for Electrical System reported it at a median of 49,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I brought a brand new BMW IX fully electric vehicle in May, 2023. A couple of weeks ago in early September, the “Emergency Call System Malfunction” warning light came on, and I can also smell a chemical burn from the vehicle. I dropped it off to Eastbay BMW in Pleasanton, California. 4350 Rosewood Drive, Pleasanton, California 94588.

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 BMW B610324 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 B610324 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 B610324 cover?
The manufacturer filed it against 24 model years: 2026 BMW 7 Series, 2024 BMW 7 Series, 2026 BMW M, 2025 BMW M, 2022 BMW X5, 2021 BMW X5 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
