2020 BMW M4 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. Fuel system
What's wrong, in plain English: Fuel lines, tank or pump. Fuel problems usually mean a leak, and leaks mean fire risk. Fuel injectors may have been installed without a damping component which is used to reduce vibration. If a damping component is not present, vibration will increase at the connection between the fuel line and the fuel rail, which over time, can result in damage at the connection.
What could happen: A damaged connection between the fuel line and the fuel rail could lead to a fuel leak and, in the presence of an ignition source, increase the risk of a fire.
The fix: BMW will notify owners, and dealers will inspect the fuel injectors and if a damping component is missing, the injectors and the fuel rail will be replaced, free of charge. The recall began December 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 2020 M4.
- Book a repair at any authorized BMW dealer. Quote NHTSA campaign 20V666000.
- 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.
