Exact make, model and year evidence from official US sources. Recall campaigns, ODI investigations, complaint allegations and EPA estimates remain separate.
A campaign may cover only certain production dates, plants or equipment. A zero result here is not safety clearance. Use NHTSA’s official VIN tool for the individual vehicle.
Exact model-level NHTSA results for 2018 BMW X4. Campaign records are official safety actions; applicability to a particular car still requires its VIN.

Complaints across nearby BMW X4 model years
Totals for the same nameplate, scaled against its highest year here. They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports. This shows where the reporting sits, not which year is better.
An investigation means ODI reviewed a possible safety issue for this exact model-year identity. Opening one is not a defect finding; closing one does not by itself clear a vehicle.

Only NHTSA vPIC, NHTSA ODI complaints and investigations, NHTSA recalls and FuelEconomy.gov contribute to this vehicle claim. CPSC equipment notices are searched separately and never joined to vehicle fitment. UK MOT, Canadian, New Zealand and European records are not merged into this US claim.
