Read by machine from the document NHTSA serves (18 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 18 model years this bulletin names have filed 751 complaints with NHTSA since 2015. 438 of them name Engine, Electrical System, Fuel/Propulsion 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 2016 BMW 3 Series, the 16 owners who gave an odometer reading for Engine reported it at a median of 100,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
In emergency situations when activating the horn, there is an unacceptable delay between when the horn is pressed and when there is actually sound produced. I have taken this up with the dealer and have been informed "that's just how it is." In looking across the internet, I see this is affecting all BMW i3 and some other BMW vehicles.

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 6127900700 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 6127900700 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 6127900700 cover?
The manufacturer filed it against 18 model years: 2018 BMW 3 Series, 2017 BMW 3 Series, 2016 BMW 3 Series, 2019 BMW 5 Series, 2018 BMW 5 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: X5 xDrive40e PHEV: built 6 Jul 2015 – 30 Jun 2018; i8 Coupe PHEV: built 16 Apr 2014 – 19 Oct 2017; F15 2016 to 2018 X5 xDrive40e PHEV: built 6 Jul 2015 – 30 Jun 2018 — the build date is on the certification label in the driver’s door jamb.
