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.

When I first purchased the car less than 90 days the engine light came on rook back to the dealership and notified Kia they didn't know why the engine light came on they said just drive it then I later told then engine light came on again and it act to over heat they said they had no signs when they did a diagnostic test they. I reported when the ac is on the engine light comes on and the car hesitates as if to stall they still saying they see nothing to indicate any problems there is problems also the back up camera stopped working the Kia customer service representative suggested to take it to another dealership the car has been to 2 different dealerships Langdale Kia Valdosta Georgia and Roundtree Moore Lake city Florida

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.

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.

My Kia Rio 2020 had the check engine light come on today. The engine coolant temperature gauge went all the way to the Hot mark. The car is one year old and and has 60093 miles on it. The dealership Demontrond Kia refused to repair it under warranty. I called Kia corporate and was told the same thing. This is unacceptable. My expectation is that they will repair this issue for no cost. As all maintenance has been done at the dealership. I have not noticed any fluid leaks nor have I been told when at the dealership about any fluid loss.

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.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER

1 complaint

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.

ELECTRICAL SYSTEM

1 complaint

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

STEERING,POWER TRAIN,SERVICE BRAKES

1 complaint

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.

1 complaint

There has not been an incident yet but i don’t 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. It’s 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 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
