NHTSA's VIN data lists these trims for the 2023 M. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 2 complaints with NHTSA about the 2023 M. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 2 recall campaigns for the 2023 M over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
BMW of North America, LLC (BMW) is recalling certain 2023 330i, 330i xDrive, M340i, M340i xDrive, M3, 330e, 330e xDrive, 430i Convertible, 430i xDrive, M440i, 2022-2023 430i, 430i xDrive, M440i xDrive, i4 eDrive40, and i4 M50 vehicles. During a service visit, a replacement electronic control unit (ECU) may have been installed with incorrect programming, which can cause the automatic door locking (ADL) function to not lock the doors as intended.
Risk: Doors that do not lock as intended while the vehicle is in motion may open during a crash, increasing the risk of injury.
Remedy: Dealers will update the ECU software, free of charge. Owner notification letters were mailed April 10, 2023. Owners may contact BMW customer service at 1-800-525-7417.
BMW of North Americal, LLC (BMW) is recalling certain 2023 8 Series Coupe (840i, 840i xDrive, M850i xDrive, M8), 8 Series Convertible (840i, 840i xDrive, M850i xDrive, M8), 8 Series Gran Coupe (840i, 840i xDrive, M850i xDrive, M8, Alpine B8 xDrive), 2 Series Coupe (230i, 230i xDrive, M240i xDrive, M2), and 2022-2023 Z4 sDrive30i, Z4 M40i vehicles. When the digital key is removed from the vehicle, the Electronic Control Unit (ECU) software may still allow the power windows and sunroof to be closed. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 118, "Power-operated Window Systems."
Risk: Unintentionally closing the windows or sunroof without the key present can increase the risk of injury to occupants inside the vehicle.
Remedy: Dealers will update the software for the Electronic Control Unit (ECU), free of charge. In addition, the digital key function via cellular service and Wi-Fi capability will be deactivated until the vehicle is updated with new software. Owner notification letters are expected to be mailed April 11, 2023. Owners may contact BMW customer service at 1-800-525-7417.
