BMW bulletin B653423
What it saysCustomers may state that the alarm system (DWA) is not active after locking their unoccupied vehicle. NHTSA’s full summary ↓
BMW filed this with NHTSA as a service bulletin dated Nov 22, 2023, received Dec 6, 2023, about the electrical system. It names 68 model years (2016–2024). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says

Depending on the vehicleâs equipment and settings, no acoustic or optical confirmation (folding the mirrors/blinking confirmation) is noticeable. Additionally, the red anti-theft alarm LED in the interior mirror does not briefly flash every 2 seconds, indicating the alarm is armed.

Read by machine from the document NHTSA serves (4 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.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 56 model years this bulletin names have filed 2,297 complaints with NHTSA since 2015. 515 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.
On the 2019 BMW X5, the 19 owners who gave an odometer reading for Electrical System reported it at a median of 55,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2019 BMW X7. The contact stated that while attempting to start the vehicle, the message that the starter motor was overheating was displayed and the vehicle failed to start. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the starter motor. The vehicle was repaired.

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 B653423 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 B653423 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 B653423 cover?
The manufacturer filed it against 68 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.
