NHTSA's VIN data lists these trims for the 2024 X3. 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 42 complaints with NHTSA about the 2024 X3. 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 3 recall campaigns for the 2024 X3 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 2024-2026 X3 sDrive30i, X3 30 xDrive, and X3 M50 xDrive vehicles. The steering spindle may have been incorrectly attached to the steering column.
Risk: An incorrectly attached steering spindle can lead to a loss of steering control, increasing the risk of a crash.
Remedy: Dealers will inspect the steering connection and replace hardware or replace the spindle and column, as necessary, free of charge. Owner notification letters are expected to be mailed October 2, 2026. Owners may contact BMW customer service at 1-800-525-7417.

BMW of North America, LLC (BMW) is recalling certain 2022-2024 X3 sDrive30i and X3 xDrive30i vehicles. The second-row seat side door locking modules may not function properly and allow the doors to be unlocked with a single motion. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 206, "Door Locks and Door Retention Components."
Risk: Doors that can be inadvertently unlocked and unlatched may open unexpectedly, increasing the risk of injury to rear seat occupants.
Remedy: Dealers will replace the second-row seat side door locking modules, free of charge. A letter informing owners of the safety risk was mailed on April 21, 2025. Owners may contact BMW customer service at 800-525-7417.

Risk: A loose steering gear can cause a loss of vehicle control, increasing the risk of a crash.
Remedy: Dealers will replace the steering gear, free of charge. Owner notification letters were mailed January 11, 2024. Owners may contact BMW customer service at 1-800-525-7417.
