2021 Kia Rio 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. Brakes
What's wrong, in plain English: Anything that slows the car down. Treat brake recalls as urgent. The brake master cylinder may have been manufactured with sharp edges that can damage the inner oil seal, resulting in reduced braking performance.
What could happen: Reduced braking performance can cause longer brake pedal travel or extend the distance required to stop the vehicle, increasing the risk of a crash.
The fix: Dealers will replace the brake master cylinder, free of charge. Owner notification letters were mailed January 11, 2022. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall SC223.
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 RIO.
- Book a repair at any authorized Kia dealer. Quote NHTSA campaign 21V936000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-333-4542.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

At speeds over 20 miles per hours there is a “flapping” noise that sounds like a bag or piece of paper that is blowing in the wind. Although I don’t know were the noise originates, I can hear it clearly from the driver’s side b-pillar. It is incredibly annoying and greatly diminishes what is otherwise a solid entry, level vehicle.
