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 B120424 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 B120424 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 B120424 cover?
The manufacturer filed it against 5 model years: 2024 BMW 7 Series, 2024 BMW X5, 2024 BMW X6, 2024 BMW X7, 2024 BMW XM. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
