Read by machine from the document NHTSA serves (10 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.
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 9 model years this bulletin names have filed 287 complaints with NHTSA since 2015. 57 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.
Cannot open rear passenger side door from the inside. Front door passenger side door locking system has also failed and had to be replaced. Rear trunk lock has failed and has had to be replaced. The rear passenger side door is a major safety issue. I could not find any notice of recalls having to do with all of these locking problems

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B011624 a recall?
No. A warranty extension 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 B011624 repair free?
A warranty extension is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does B011624 cover?
The manufacturer filed it against 9 model years: 2019 BMW 3 Series, 2018 BMW 3 Series, 2019 BMW 5 Series, 2018 BMW 5 Series, 2018 BMW 6 Series, 2019 BMW 7 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: F30 2018 320i Sedan, 320i xDrive Sedan: built 15 Mar 2018 – 8 Oct 2018; built 16 Mar 2018 – 11 Oct 2018; F30 2018 330e iPerformance: built 16 Mar 2018 – 5 Oct 2018 — the build date is on the certification label in the driver’s door jamb.
