NHTSA's VIN data lists these trims for the 2025 X4. 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 4 complaints with NHTSA about the 2025 X4. 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.

What the columns count
Complaints: complaints that name that part. One complaint can name several parts, so the rows overlap and don't add up to the total.
Crashes and Fires: complaints that report one. Two owners can file about the same event, and NHTSA doesn't link them, so these count reports, not events.
Injuries: the number of people the complaints say were injured.
None of these columns shows that a part caused a crash, fire or injury: they're what owners reported, unverified.
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 1 recall campaign for the 2025 X4 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.
