2021 Kia Rio Service and Repair Manual
The 2021 Rio was built to its own factory specifications, and this service and repair manual is matched to that exact year, engine and trim — so the torque value, clearance or fluid capacity you look up is the figure written for your car, not a near-match borrowed from another model year.

Known issues on the 2021 Rio. Two recalls are on federal record for this model year. The first concerns the steering column: on certain 2021-2022 Rio and Forte vehicles, a bolt in the steering column may not be secured properly, and loss of steering control can increase the risk of a crash. The second concerns the brake master cylinder, which may have been manufactured with sharp edges that can damage the inner oil seal; reduced braking performance can cause longer brake pedal travel. Owners have filed 23 complaints for the year and Kia has issued 57 technical service bulletins.
Whether you are chasing one of those known faults or working through routine maintenance on the 1.6L four, it keeps you on the OEM procedure and the correct specification for your specific 2021 Rio.

Having been complaining about a noise from under the front right tire, I was initially told it was a little piece of plastic and that got cut off. I was still hear the scraping and squealing and I kept check the from right tire because I thought that's where it was coming from. I mentioned this to every mechanic at kia and was told "that's just how 2021s sound". Finally after months of complaining the noise got louder and you could hear it was clearly something in steering. They schedules an app
Vehicle failed to reduce speed effectively while trying to avoid a collision with another vehicle during a left turn, which then caused the vehicle to turn widely and collide with the curb.
Back up camera sometimes flips sides, so that obstacles on the right side of the car are shown on the left side of the camera screen. Sometimes the camera doesn't work at all.
Placed car in park got out to open a gate. Car took off forward even when shifter was in Park Position and almost ran a child over.
I had driven my wife to her school about 5 miles and headed back to my work another 5 miles when i tried to accelerate pass car I lost almost all power barely making it up a slight hill I kept going trying to make it to my house barely going 10 miles an hour. I thought the transmission had let go cause while I had the gas peddle floored i went at best 10-15 miles an hour I eventually parked the car I knew it would never make it up another slight hill. It was rowed to a nearby dealer where t
Center Console Display blank (screen black) upon startup unable to see cameras and backing up affected creating safety concern.
The steering wheel column does not have a lock therefore someone broke into my car and tried to steal it and destroyed it, also no alarm went off when this happened.
On the way to work, I had the brake pedal pressed waiting for a traffic signal to change. After it changed to green, I released the brake pedal and depressed the gas pedal, only for the vehicle not to move forward - as if the brake was still being applied. I took my foot off the gas pedal, waited a second or two, then tried the gas pedal again and it still did not move. I was at the traffic signal for nearly 10 seconds with nothing touching the brake pedal and unable to drive forward. The vehicl
Steering Gear Assembly completely broke at 81,000 miles. My daughter was backing up in a busy street at 5pm and lost 100 percent of steering control. Lucking cars dodged her and she didn’t get hurt or worse.
seatbelts in rear are inoperable/anti theft not working. Kia dealership told me that its not their issue about the anti theft. I have been told on 3 separate occasions that my seatbelts have been ordered but they haven’t!!!! No one is following up with me, when I call I get told “until they can get in contact with the dealership Kia the corporate company cannot do anything” have 2 kids Kia the dealership as well as the corporate company knows about this and no one is doing anything!! NO ONE CARE
I was driving 60-70 miles an hour for 45 minutes then car lost all acceleration and engine light came on. I pulled over immediately turned the car off. Turned it back on drove 1/4 of a mile and same thing happened. I pulled over turned car off and had it towed to the dealership.
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.
On 3/19/23, as I was driving on a dry, straight, two lane road at the posted speed of 40mph, the car began to try to steer into oncoming traffic. I had to exert moderate force to keep the car in my lane. This continued continuously for about 1/2 mile. No low tire pressure indicator lights were illuminated, however the lane assist icon was on and green, indicating normal operation. Just as I was going to turn down a side street to check the tires manually, the steering returned to normal. However
The contol post for lights, turn signal, and high beams is too sensitive. To control the lights, you twist the top of lever. To turn on turn signals, you flip the lever up or down. To turn on brights, the lever goes forward. To turn of lights, the lever is pulled back. The issue..... If you have brights on, when you pull lever back to dim lights, the top automatically twists to shut off the headlights entirely. DANGEROUS DANGEROUS DANGEROUS. My husband doesn't have this problem, but he ha
