2020 Kia Rio Recalls, Issues & Maintenance

The 2020 Kia Rio carries 1 open NHTSA recall — most recently covering master cylinder. Owners report 6 recurring issue clusters, led by “Brake master cylinder and pedal feel degradation.” Kia uses Hyundai Motor Group's powertrains, so service intervals mirror Hyundai's. Kia Promise covers the first 3 years / 36,000 miles of complimentary maintenance. Kia owners with the Theta II 2.0L/2.4L (Optima, Sorento, Sportage 2011-2019) should adhere strictly to oil intervals due to known oil-consumption issues in Kia TSBs.

Campaign #21V936000 · Jan 12, 2021

Issue: Kia Motors America (Kia) is recalling certain 2020-2021 Rio vehicles. The brake master cylinder may have been manufactured with sharp edges that can damage the inner oil seal, resulting in reduced braking performance.

Risk: Reduced braking performance can cause longer brake pedal travel or extend the distance required to stop the vehicle, increasing the risk of a crash.

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.
