2021 Toyota Corolla recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
1 safety recall, 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. A short circuit may develop in the Occupant Classification System (OCS) sensor, preventing the front passenger air bag from deploying.
What could happen: An air bag that does not deploy during a crash increases the risk of injury.
The fix: Dealers will inspect and replace the sensor as necessary, free of charge. Interim letters notifying owners of the safety risk were mailed in February 2024. Some final remedy owner letters were mailed October 31, 2024. Letters will continue to be mailed in phases through January 2026. Owners may contact Toyota custome…
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 COROLLA.
- Book a repair at any authorized Toyota dealer. Quote NHTSA campaign 23V865000 (manufacturer code 23TB15/23TA15 Lexus 23LB03/23LA03).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-331-4331.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

"Engine maintenance required" light is coming up constantly, only when i turn on the AC and doesn't let me view my dash at all. Ive determined it's the Engine coolant bypass valve. Many models have had this same exact issue and there needs to be a recall/repair at no cost to the owners.
