2021 BMW X4 recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
7 safety recalls, most serious first
1. Backup camera
What's wrong, in plain English: The rear camera may not show an image when reversing. A small portion of the rearview image may be slightly obscured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."
What could happen: If the driver relies on only the rearview camera image, the reduced rearview image view can increase the risk of a crash or injury.
The fix: BMW will notify owners, and dealers will inspect and, if necessary, program the rearview camera with updated software. The recall began November 18, 2020. 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 2021 X4.
- Book a repair at any authorized BMW dealer. Quote NHTSA campaign 20V598000.
- 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.
