BMW bulletin B012021
What it saysFor the eligible vehicles, BMW of North America, LLC (BMW NA) is extending the limited warranty for the vehicle's Fuel Injectors to: 15 years/150,000 miles as determined by the vehicle's original in-service date. NHTSA’s full summary ↓
BMW filed this with NHTSA as a service bulletin dated Nov 1, 2021, received Dec 27, 2021, about the electrical system. It names 6 model years (2016–2021). 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.

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 6 model years this bulletin names have filed 114 complaints with NHTSA since 2015. 26 of them name Electrical System, Fuel/Propulsion System, 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.
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.
2017 BMW i3 · Electrical System · filed with NHTSA Jul 1, 2022 · ODI 11471951
The car has lost power on the highway multiple times and gone into Limp mode with no warnings on the dashboard. The Rex engine has failed to start as well.

On May 2, 2022, the car began to power down involuntarily every time I applied the brakes. This happened 2-3 times, and I was able to restart. The final time was in the middle of an intersection, the car would not restart, could not be placed in neutral to be moved out of the intersection, and I had to have a police tow.

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 B012021 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 B012021 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 B012021 cover?
The manufacturer filed it against 6 model years: 2021 BMW i3, 2020 BMW i3, 2019 BMW i3, 2018 BMW i3, 2017 BMW i3, 2016 BMW i3. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
