Read by machine from the document NHTSA serves (9 pages), read Sep 30, 2026. A part number is shown only where it matches BMW’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 40 model years this bulletin names have filed 1,354 complaints with NHTSA since 2015. 464 of them name Engine — 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.
On , I was driving down the road and a indicator light went off, indicating a malfunction. When I pulled over to the side, I shut the car off. I noticed something around the drivers side front end of the car. When I exited the vehicle, I seen fire (flame) coming from the front drivers side. It was located right in front of the tire.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B011423 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 B011423 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 B011423 cover?
The manufacturer filed it against 50 model years: 2021 BMW 2 Series, 2020 BMW 2 Series, 2019 BMW 2 Series, 2018 BMW 2 Series, 2017 BMW 2 Series, 2016 BMW 2 Series and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: Coupe: built 9 Jun 2016 – 24 Jun 2021; xDrive Convertible: built 13 Jun 2016 – 5 Jul 2021; built 11 Jun 2015 – 11 Oct 2018 — the build date is on the certification label in the driver’s door jamb.
