2023 BMW X4 recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
2 safety recalls, most serious first
1. Transmission / drivetrain
What's wrong, in plain English: The parts that send engine power to the wheels. Failure can mean a sudden loss of power or the car rolling away. The weld seam of the integrated transmission control unit's cover may not have been manufactured properly, which could allow automatic transmission oil to leak into the transmission control unit.
What could happen: Transmission oil that leaks into the control unit can lead to a seizure of the transmission gears, causing a sudden loss of drive power and increasing the risk of a crash.
The fix: Dealers will replace the transmission mechatronics module and the automatic transmission fluid, as necessary, free of charge. Owner notification letters were mailed January 26, 2024. Owners may contact BMW customer service at 1-800-525-7417.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2023 X4.
- Book a repair at any authorized BMW dealer. Quote NHTSA campaign 23V821000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-525-7417.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
