There are 1 owner-reported brakes complaints for the 2022 Kia Rioin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
When traveling 60 mph and slowing to try to stop, brake pedal went all the way to the floor and vehicle would not brake. Had to engage emergency brake to stop vehicle during normal operation on multiple occasions. Once while stopped at a red light, vehicle was completely stopped, then the brake pedal lowered to the floorboard and the vehicle started rolling forward. I had to turn the steering wheel and engage the emergency brake to avoid colliding with traffic. No dashboard lights came on, no warning lamps or messages. No other symptoms. I went to the Kia Dealership immediately. There was a hole in my front brake line and all of the fluid had leaked out. Vehicle was less than 2 years old, less than 100,000 miles on it.
