The 2020KIARIO carries 36 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 5 crashes, 9 fires, 1 injury, and 9 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall Not Rated/5 rating, with Not Rated/5 front crash, Not Rated/5 side crash, and Not Rated/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2020 RIO is unknown or other with 7 filings, followed by engine (5) and steering (4). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 1 active recall campaign, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 38 investigation files overlapping the 2020 RIO, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:MASTER CYLINDER
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.
Upon stopping at a red light and or stop sign, when applying brakes, the car continues to move forward, even after pumping the brakes. Vehicle has been diagnosed by a certified auto mechanic. The findings and recommendation for the Brake Master Cylinder to be the reason the vehicle continues to creep forward, when brake are applied and held. This issue has on two separate occasions near collision, because the vehicle wouldn't stop.
I was driving up a hill and it would not go past 20-30 mph, and the rpm will sometimes go up when not accelerating. The transmission does not shift when driving and will sometimes make the car stop and go stop and go continuously. Tried accelerating but the rpm would go up while the mph would not.
I went into a rural King store to shop when I came back out my car was completely filled with smoke. I opened the front passengerdoor and the smoke hit me in the face it was so thick and green it was just it took my breath. It took me 10 minutes to locate what had happened and down on the door frame of the passenger side of the front seat where the wiring is there was a whole melted all the way through that panel and you could see the wiring was exposed so I assume that the wiring had caught on fire. I'm not sure about this it has been looked at and it is at Jeff Wilder Toyota in Clarksville Indiana. They want me to pay $1,000 deductible for this but I feel like if it was a wiring issue key is should be responsible. I am going through a flood right now in my home and now I have to deal with that and I don't think I'm even responsible for the payment I think he is at the cover it.

I came out of a store last week and there was smoke inside my car and when I opened the door there was a hole down by the door frame on the passenger side that it burned all the way through to the frame of the car and now my lights are flashing on and off and sometimes a passenger headlight works sometimes the driver had light works but it's either one or the other it's doing all kinds of crazy stuff with the lights now I'm thinking it has to be in the electrical fire because it got hot enough to melt all the way through the plastic part of the bottom of my door I do have pictures
Recall SC223 Brake master cylinder. Rough metal edges can pinatrate Seals causing leaks poor braking functionality. NHTSA Capaign ID# 21V936000. Nov.30th.2021, 87 vehicles effected. Clay Cooley kia refused to honor the recall and fix the problem with my vehicle on 10/25/2024. Recall on the catalytic converters. Recall SC176 , Carbon monoxide poisoning due to exhaust systems malfunctioning and exhaust coming through the AC system. When I took my 2020 Rio S to Vanguard Kia Arlington Texas. Vanguard kia refused to honor the recall because my vehicle had over 80,000 miles and that's why Vanguard Kia service advisors wouldn't replace the catalytic converters. Or Vanguard kia would have replaced them! Even though it was a Safety issue. My wife and I recently was admitted to Parkland hospital for carbon monoxide poisoning levels of tests taken at the hospital blood gas tests were above level 9 for carbon monoxide poisoning. My level was 13. So now we're having to drive our 2020 rio s wi

I believe my Kia Rio S falls victim to the recall 2020 Kia Rio models have faced. Brake performance has been severely degraded on my vehicle over the past few weeks despite doing all recommended maintenance. When I first got my 2020 Kia Rio S I could brake with 5% pressure applied to the brakes, now it takes about 25-30% pressure and it seemingly is increasing every day. I have contacted the manufacturer and they advised me it would be a $2000 service charge minimum.

My car acted like it haD a dead battery. This happened once before and after about 10 minutes when I tried starting it it started with no problems. this happened a couple of months the ago. This time, as I was sitting in the car the seat belt light came on but I couldn't wait for the issue to resolve.
I was driving at just over 20,000 miles, when cylinder 4 decided to go out of the bottom of my engine. They had to put a completely brand new motor in my car. So, what's stopping it from doing it again. There's other cars listed in a Kia/Hyundai settlement, but the Kia Ria is not listed.
There has not been an incident yet but i donât know who else to talk to. I am a FedEx Delivery driver and driver the largest Delivery truck made for FedEx and am fine with it ask day. However, the steering on my car is down right dangerous. My car drifts all over the road. It is ten times harder to keep my little cat on the road than my big work truck. So hard in fact that i have resorted to this. I am a good driver never even a ticket so i know how to drive. Itâs not my driving please listen when i tell you something is WAY wrong with the steering or suspension or both on this vehicle. Just drive one and you will see very quickly what i am saying i promise!

Yes my son bought this car last year I have been checking since January there has still been no recalls on his particular car he was in a car accident and unfortunately him and his passengers were all killed. I have contacted an attorney who has sent an inspector they said initial look it look like something to do with a rod in the engine and it catching fire but from other things itâs possible he couldâve had other problems dealing with the brakes the emergency assistance. So they think possible electrical and what else they have not said. They are getting with Kia to get his car moved there so they can have one of their people take it apart to preserve evidence to find out which or if many of the recalls had happened to his more happened to his car
