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.

What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 326 complaints with NHTSA since 2015. 18 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.
I am started to lease this car in August 2024. After 2 weeks, the car just halted, unable to move. Luckily this happened in my driveway. It took BMW more than 1 month to repair this. They had to change the combined charging unit with a different part number (upgraded part). At that time the car had roughly 200 miles on the odometer.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B110723 a recall?
No. A emissions communication 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 B110723 repair free?
A emissions communication 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 B110723 cover?
The manufacturer filed it against 8 model years: 2024 BMW 7 Series, 2023 BMW 7 Series, 2024 BMW X5, 2023 BMW X5, 2024 BMW X6, 2023 BMW X6 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: G05 X5 Sports Activity Vehicle: built 8 May 2023 – 17 Jun 2023; G06 X6 Sports Activity Coupe: built 8 May 2023 – 17 Jun 2023; G07 X7 Sports Activity Vehicle: built 9 May 2023 – 14 Jun 2023 — the build date is on the certification label in the driver’s door jamb.
