Read by machine from the document NHTSA serves (9 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 3 model years this bulletin names have filed 222 complaints with NHTSA since 2015. 57 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.
The car stopped without any warning 3 time in the middle of the road while driving my wife and kids inside the car. I consider very lucky this happened on county road two time and ones in the shopping center parking lot, instead of middle of the highway.

The dealer performed the EGR Cooler recall in Feb 2023, a month later and the part failed again. BMW should be required to issue a lifetime warranty on these defective parts that have now been recalled twice
2018 BMW X5 · Engine · filed with NHTSA Mar 17, 2023 · ODI 11512444
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 6412900100 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 6412900100 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 6412900100 cover?
The manufacturer filed it against 3 model years: 2018 BMW X5, 2017 BMW X5, 2016 BMW X5. 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: built 6 Jul 2015 – 30 Jun 2018 — the build date is on the certification label in the driver’s door jamb.
