Recalls on the 2020 KIA RIO
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
United States — NHTSA
21V936000
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.
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.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 202173029 units in Canada
Brakes
Issue: On certain vehicles, the brake master cylinder could fail and cause reduced braking. If this happens, the driver may experience increased brake pedal travel and a change in brake pedal feel (soft or low pedal). Safety Risk: Reduced brake performance can cause extended stopping distances and increase the risk of a crash. Corrective Actions: Kia will notify owners by mail and instruct you to take your vehicle to a dealer to replace the brake master cylinder.
Reports where the owner recorded a crash, a fire, an injury or a death.

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.

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 it’s possible he could’ve 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

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 with the windows down and the ac vents closed. To keep from getting carbon monoxide poisoning again!! Please help us get these 2 SAFETY RECALL ISSUES FIXED. We cannot afford it out of pocket. Kia Should honor their recalls. vehicle owners.

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.
