What it saysDelivery stop: variable valve timing NHTSA’s full summary ↓

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.

2026 BMW X5 · Engine · filed with NHTSA Sep 24, 2026 · ODI 11766793
I am started to lease this car in August 2024. After 2 weeks, the car just halted, unable to move. Luckily this happened in my driveway. It took BMW more than 1 month to repair this. They had to change the combined charging unit with a different part number (upgraded part). At that time the car had roughly 200 miles on the odometer.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B120626 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 B120626 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 B120626 cover?
The manufacturer filed it against 8 model years: 2026 BMW X5, 2025 BMW X5, 2024 BMW X5, 2023 BMW X5, 2026 BMW X6, 2025 BMW X6 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: 2024 – 2027 BMW: built on or after 9 Mar 2023; F95 X5 M Sports Activity Vehicle: built 13 Mar 2023 – 7 May 2026; F96 X6 M Sports Activity Vehicle: built 9 Mar 2023 – 7 May 2026 — the build date is on the certification label in the driver’s door jamb.
