Summary
The KIA Rio has 16 recalls spanning 2001 through 2022, with the most serious recent issue being a 2021-2022 steering column bolt that can come loose, allowing the column to detach from the steering rack and leaving the driver with no steering control.
The 2020-2021 model years have a brake master cylinder where sharp internal edges can damage the oil seal, reducing braking performance and extending stopping distances. The 2020 model year carries a related concern where the brake master cylinder can fail outright, causing a soft or low pedal feel and further lengthening stopping distances.
The 2018-2019 models have a trunk latch that can fail and prevent the internal emergency release from working, which could trap a person inside the trunk. The 2018 model year also has a compliance label misprint affecting the gross axle weight rating, though this carries no direct safety consequence.
Going back to the 2006-2008 model years, the front passenger seat sensor mat can develop cracks over time and misread the seat occupant. When this happens, the front airbag may deploy toward a child seated in the front passenger position, raising the risk of injury to that child.
The 2003 model year has three related child restraint issues: the rear outboard seatbelt automatic locking retractor can disengage when used with certain child seats, and the lower anchor hardware can prevent a child seat from fully engaging its anchor points. Either condition leaves a child seat less secure in a crash.
The 2001 model year has two clusters of concern. The wheels can develop fatigue cracks that worsen progressively, and in a severe case a wheel can separate from the vehicle entirely. Separately, the fuel distributor's intake nipple can fracture or crack, allowing fuel to leak near potential ignition sources and creating a fire risk in the engine compartment.
