What owners reported
Source: NHTSA complaint databaseOwners of the 42 model years this bulletin names have filed 2,132 complaints with NHTSA since 2015. 480 of them name Engine, Fuel/Propulsion 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 2016 BMW 5 Series, the 18 owners who gave an odometer reading for Engine reported it at a median of 80,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I had stopped uphill, with my foot on the brake, heading East on the left lane of Pomona Road, at the approach to the Traffic Light Junction with Route 45, around 3.50 PM on Friday 1/23/2026. There were about 5-6 cars also stopped, ahead of me, at the Red Traffic Light and several cars behind me, when I heard my car engine rev up loudly.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B160623 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 B160623 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 B160623 cover?
The manufacturer filed it against 53 model years: 2024 BMW 5 Series, 2023 BMW 5 Series, 2022 BMW 5 Series, 2021 BMW 5 Series, 2020 BMW 5 Series, 2019 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.
