Read by machine from the document NHTSA serves (5 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 4 model years this bulletin names have filed 104 complaints with NHTSA since 2015. 8 of them name Power Train — 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 vehicle is equipped with a dual clutch transmission and has the EPA mandated auto-start feature. When you stop the vehicle and the engine shuts off and then remove your foot from the brake to go forward, the engine hesitates to restart and then starts, revs, dumps the clutch and propels you forward at a dangerous rate.
2023 BMW X1 · Power Train · filed with NHTSA Jul 11, 2024 · ODI 11601283
Our X1 has a lot of "slip" in the transmission. It's most apparent when you back up and then switch to drive. In our X1, the car keeps rolling backward like it's in neutral. Drive doesn't engage until after a long delay
2024 BMW X1 · Power Train · filed with NHTSA Jan 8, 2026 · ODI 11709771
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 0028240100 a recall?
No. A service campaign 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 0028240100 repair free?
A service campaign 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 0028240100 cover?
The manufacturer filed it against 4 model years: 2024 BMW X1, 2023 BMW X1, 2024 BMW X2, 2023 BMW X2. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
