BMW filed this with NHTSA as a service campaign dated Jun 7, 2024, received May 3, 2024, about the engine — 3 documents under this number. It names 7 model years (2018–2022).

Read by machine from the document NHTSA serves (7 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.

Despite following the manufacturer’s recommended maintenance schedule and having the car serviced at authorized BMW dealerships, I am facing an engine failure that BMW has quoted $44,000 to repair.

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 B170324 a recall?
No. A service campaign 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 B170324 repair free?
A service campaign 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 B170324 cover?
The manufacturer filed it against 7 model years: 2022 BMW 8 Series, 2022 BMW M, 2021 BMW M, 2020 BMW M, 2019 BMW M, 2018 BMW M and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
