What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 30 complaints with NHTSA since 2015. 2 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.
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

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B280324 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 B280324 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 B280324 cover?
The manufacturer filed it against 1 model year: 2024 BMW X1. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
