Source: NHTSA, updated daily. Last checked 2026-10-19. Recalls apply to specific VINs — run your VIN to confirm.
6 safety recalls, most serious first
1. Airbags
What's wrong, in plain English: The airbag system — the part that is supposed to protect you in a crash. The side curtain air bag inflators may have been manufactured with the incorrect amount of compressed gas, which can result in improper air bag inflation. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard numbers 226, "Ejection Mitigation," and 214, "Side Impact Protection."
What could happen: An air bag that does not inflate properly can increase the risk of injury in a crash.
The fix: Dealers will replace the side curtain air bags, free of charge. An interim owner notification letter was mailed on February 3, 2022. Owner notification letters were mailed on April 22, 2022. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 21C37.
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 MUSTANG.
- Book a repair at any authorized Ford dealer. Quote NHTSA campaign 21V980000 (manufacturer code 21C37).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-866-436-7332.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

3. Electrical system
What's wrong, in plain English: Wiring, modules, batteries. Short circuits can cause stalls or fires.
