My Kia has been stalling, shaking, and just driving extremely badly for the past year. This day, I was driving on 55, and the car just stopped and stalled in the middle of highway near Berwyn, IL. This was extremely dangerous and could have honestly been life threatening. I pulled over, turned the car off and on, and was safely able to drive it to Berwyn Kia. Unfortunately, this was not the only time that this has occurred and I’m assuming will not be the last. In addition, I was charged $500+ to replace piston rings that were recalled on other models that were not recalled on my model, even though the same year was recalled.

The infotainment head unit display system suffers from persistent firmware connectivity defects that cause severe system lag, complete screen freezing, and constant Bluetooth/phone disconnections. This directly compromises vehicle safety by rendering mandatory hands-free voice operations completely inoperable while driving, creating an intense electronic driver distraction. Furthermore, the system instability occasionally causes the central display screen to lag or fail to transition, impacting the reliability of the backup camera display. The manufacturer (Kia America) does not provide a functional consumer download path to patch the firmware build, and the local franchised dealer (Arapahoe Kia) explicitly refuses to service or update the component, leaving the vehicle with an ongoing electronic defect.

This has happened 3 other times. It just stalls out when stopped. Not to do its SMART thing but it clunks-like and turns completely off. Its a bit scarey. And now heat issues just like the last 2 summers. It has issues!

Piston oil ring recall update complete in July 20 25. A month later key fob battery dies. Replaced key fob battery every other month since recall. September 20 25 had brakes and rotors changed at dealership since then anti-slip alert has triggered twice on dry roads. Light comes on then immediately goes off. Remote car starter stopped working in December. Dealership had no resolution for key fob issues and has not been able to replicate anti-slip issue. Dealership currently has vehicle to attempt to replicate issue and to look into the remote car starter issue. This is unsafe because the car automatically shutters and feels uncontrolled slip comes on also causes issues when key fob consistently dies every other month and get alert, letting me know that the key fob has died. And while the remote car starter is not a safety issue, it is all tied in with the electrical issues that are happening. The issues started after the recall was added to my vehicle.

DEATH TRAP! Point blank~Engine will STILL Jerk, Skip, Not Do Anything Or even Shut Off Without Warning!!! The Driver's Screen will still Flash and go out but only once in a while now. Dealership didn't understand that. They told me Radio was Fine Now. I told them Screen Directly in Front of Driver's with Speedometer on it. IT'S HARD TO FIND GOOD HELP. EVEN HARDER, to FIND a SAFE RELIABLE VEHICLE that YOUR KIDS CAN BE IN!!! 💯% 🎯 RUST {definitely} up under Near the License Plate Bracket. ALSO, the Windshield WIPERS STOP WORKING WHENEVER THEY CHOOSE!!! The Best part is, the Dealership CAN'T DO ANYTHING about ANY OF THIS. Why? Pretty much because KIA REDID the TEST so that ALL the Vehicles PASS Now. It makes it LOOK like the Engines are OK, when in Reality they are 💩. I bought this Vehicle 12-30-24 with 44,068 miles on it. My Daughter and I thought we were going to Die in it on 4-26-25. We didn't even have it a full 4 months Before We Found Out WE HAVE A LEMON from KIA. There were 3,310 Miles put on it. Come on... I was told there was No Way to NOTE My Account at the Dealership for the Different Times {Everytime} this NEGLIGENT 💩 STUFF Kept and Still Does Happening. That's OK. I just Hope and Pray for KIA's sake, that Nothing Ever Seriously Happens to Anyone because of How THIS 2021 KIA SELTOS VEHICLE Operates DEFECTIVELY in So MANY DIFFERENT WAYS that ARE SAFETY HAZARDS. IF they were Smart, they would REPLACE ALL OF THEM with a Brand New Vehicle to AVOID A POSSIBLE SERIOUS FATALITY. I only say this because that's what WE experienced more than once. We fear this Daily. We ended up with this Vehicle after our Honda CRV-EXL was Totaled by Someone running a Red Light. It was the OTHER PERSON'S FAULT, but after paying off car... Kia was all in could afford. I had NO Choice but to get this KIA. Being a Single Mom on Low Social Security Disability Income, I did what I had to do! I have to have a GOOD RELIABLE AWD VEHICLE to get to Doctors Appointments. THIS ISN'T ONE.

My car has stop many times in highway running 55mph or 30 mph. It will completely stop my car has almost 15000 miles a 2021 kia seltos. I turned in my car to the kia dealershop to get check and they diagnosed a lot for so many things and have me pay to replaced the car’s battery. I had my 3year olf child when that happened The dealer just pushed it that it was the battery but its not. My car has only 15000 miles. they also ordered a pad crash main even whwn there was no accident happened. It is a critical safety of my component. For a very low milage car that has so many problem i think this is not good. The engine will stop when i pressed the brake and automatically refresed all warnings will show mainly engine light. it wont turn on when i pressed the button. It happen many times

My vehicle is currently in the shop at the local Kia dealership. Over the past week my vehicle has randomly stalled several times. The engine sounded like it was sputtering, and just not accelerating properly. The car would stall at low speeds while turning corners or pulling into a parking spot. I do not have the diagnosis as of yet but believe my vehicle should be considered one of the recalled engines due to its date manufactured and the current issues that are occurring. Noticed stalling at speeds 45mph or less. It's very frustrating with a vehicle having 82,000 miles on it. All mandatory maintenance has been done at correct intervals and now this. It needs to be reported.

Incident

Jun 6, 2025

The vehicle in question has been experiencing multiple ongoing mechanical issues, including engine stalling, frequent brake replacements, frequent oil changes, a camshaft issue, and intermittent horn functionality. These issues have raised serious safety concerns. Despite multiple repairs and maintenance attempts at the dealership, the problems persist, affecting both my safety and confidence in the vehicle. I have incurred substantial costs for repairs and rental cars while trying to address the issues. However, the problems remain unresolved, and I am not receiving adequate support. I contacted the corporate office for assistance, but the representative dismissed my concerns and stated I would need to provide maintenance receipts, even though the dealership had already confirmed they were unnecessary. This response was unhelpful and failed to address my safety concerns. Additionally, the service manager at the dealership has not offered satisfactory solutions or alternatives to resolve the ongoing issues. As a result, I am no longer comfortable continuing with the vehicle. Due to my financial situation and outstanding loan balance, I am requesting a goodwill replacement vehicle or a reasonable alternative that will allow me to maintain my current car payment without a substantial down payment or negatively impacting my credit. A replacement vehicle, ideally of the same make and model or comparable, would help me meet my financial obligations while addressing the unresolved safety and reliability concerns.

I bought my ‘21 Kia Seltos in 2021. Within the first months it would stall when going uphill and in parking lots. I had a few mechanics look and they could not find any issues. So, I kept driving it. I drive 12 miles one way for work my wife drives it 1 mile both ways for work. Now [XXX] 47k miles it stalled out 2x the 2nd time it stalled it started to fill with fumes and smoke with my [XXX] - and [XXX] in the car. My kids and I have had a cough ever since. I called roadside; they first thought was the battery. So, the first guy tried to jump the battery, and nothing happened then he said he smelled something electrical burning. But could not locate. Then he said they will send a tow. Roadside then sent another guy to jump the battery. he smelled the same thing, but he found the source and said that the airbag sensors were burning. So, he disconnected the battery and called the tow. The car was towed at midnight to Grand Kia in Northglenn where the service rep was working on my car called me that day to tell me that the engine had seized, and he would submit a warranty claim to have it covered. I provided all service records to him including oil purchase receipts. A week later he calls and tells me they denied the warranty due to “lack of maintenance”. So, I call Kia customer care and speak with A lady who tells me it was denied due to “aftermarket parts” which there were none. She said once that flag was removed, she can escalate this case to a case Manager. Then I call Grand Kia back and talk to the service rep who says that flag is not there. Then I call back Kia and a different lady tells me the case was escalated and to expect a call and an email from the case manager. I call 4/10/2025 and am being told there is not an escalation on the case. I get transferred to a supervisor line and after waiting on hold I had to leave a voicemail, still no returned call. All this while there is a safety recall out that causes my exact issue and the engine needs replaced. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I

Incident

Mar 30, 2025

I brought my vehicle to the dealership due to serious safety concerns, including the engine randomly shutting off while driving, sudden unintended acceleration, unresponsiveness when pressing the gas, difficulty turning the key to start the engine, loud noises while running, and the engine, battery, and oil lights coming on. This is the second time I’ve brought the vehicle to the Kia dealership for the same issue. The first time, I was told the transmission had been replaced and the problem was resolved. However, the same issue resumed shortly after I got the car back. I called the dealership that day but they were already closed, so I dropped the vehicle off the next morning when they opened. At drop-off, I was told no repairs could begin until the recall was “officially” announced, but that they would look into the issue and keep me updated. Unfortunately, I never received any updates and had to reach out myself multiple times. This morning, I was told the sensor lights showing were “old codes” and that everything seemed fine. They said they’d take the car for a test drive and that I’d have it back by the end of the day. No one called me back. I followed up around 4:30–5:00 PM and was told the service department had closed, but the notes said that after the test drive, more codes appeared and the vehicle would require additional work. When I first dropped the car off, I was told I’d have it back the next morning, and if not, I’d be provided with a rental. Neither happened. When I expressed that I didn’t feel safe driving the car—even if the test drive went well—especially after a mechanic told me he wasn’t sure how to fix the current recall, I was dismissed. As I was saying, “Okay, just call me after the test drive so I can come by and check it out,” Greg hung up on me mid-sentence. This entire experience has been frustrating and concerning given the nature of the issue.

I was driving down the highway going 65mph when my car would not accelerate any more in the middle of the highway where the speed limit is 65. At one point I could not get it to go above 30mph. I pulled off to the side and when I tried driving off again my car would not accelerate. Towed to Kia, they did a software update thinking it was fixed. Picked my car up and drove 10 miles before it broke down on me again. Towed to a second Kia dealership, new transmission was put in. Picked it up 4 days ago, and it is stalling, and jolting when accelerating and the check engine light is on. It is at the 3rd Kia dealership, where I was just told I may need ANOTHER transmission replacement. I asked about the engine recall after getting an email from Kelly Blue Book about it. Kia said they did not know how to fix the recall yet and there was nothing they could do about it right now. I have been without my car for almost 2 months, and this is the 3rd Kia dealership trying to fix the issue at hand and not getting anywhere.

When the auto engine start/stop button is on and I’m stopped at a light, the infotainment system will constantly restart as will the engine once I let go of the brakes. It usually happens when it is cold outside. This is a safety issue bc a lot of the time I am using the navigation and since the infotainment system just restarted I am waiting for the navigation to reboot and I am now driving without knowing where I am going. It doesn’t seem to happen when I turn off the auto engine start/stop button. Sometimes, I’ll be in an intersection, and the engine will restart bc the infotainment system restarted. Last time I almost got into an accident bc I was trying to accelerate but the car hesitated bc it restarted the engine and radio. There seems like there is a sudden loss of power. The dealer supposedly updated the software for the infotainment system but it did not correct the issue. There is no warning lamps or messages when this occurs

I’m not really sure what the problem was. I feel like the car may have lost power and I lost function of the car / brakes. I’m assuming it’s either an engine or electrical. Warning lights came on. Prior to losing function, the vehicle felt like it was sorta puttering. I’d give it the gas and there was a delayed, and then jerk forward. There’s a vibration sound that happens when I go around 15-30 miles an hour. Not sure if it’s related. It’s being looked at on June 24. I had to turn off the car and restart to gain control.

You are driving with all windows up in Florida with the temperature outside from 70's to 90's Degrees with AC on cold and running and suddenly car displays the temperature outside -39 Degrees and the car starts blowing very hot air that fogs all windows within seconds and daughter is unable to see. Car has been taken to Kia of Leesburg, FL more than 5 times. Dealer has changed the temperature sensor and checked the wiring, but the vehicle is still doing the same. Daughter almost had 3 major accidents because of this with 3 year old in the car. Need NHTSA to investigate this and push KIA of America for resolution.

The car initially had electrical and engine issues since may of 2022. The engine would fail mid drive and the car would turn of in the middle of driving and would lock up until engine would restart on its own. It stayed at the dealership for repairs until march of 2023. After many modifications and alterations and several new engines and transmission changes they returned the car to me on march of 2023 assuring me it was fixed and there would be no issues. Several weeks later while driving on the highway, the engine turned off mid drive, I lost control of the car entirely. Brakes wouldn’t brake. Car crashed into highway median. And upon impact none of the airbags deployed. The car continuously put myself and passengers at risk at the beginning of its failing. The car of April 2023 severely injured me. I was the only passenger at the times thankfully. Since the airbag never deployed my face, chest, ribs, arm, and neck were severely injured. It’s been almost a year and im still physically affected by the crash.

My vehicle appeared to restart itself (dashboard lights turned off and immediately turned back on as if the car had been started up) as I was a approaching a red stop light toward the end of a 1 hour/60 mile commute. This is the 3rd time since I've had my vehicle (purchased in October of 2020) that I've had an event like this occur while driving. Currently waiting service appointment, 2 weeks away 1st incident, within the 1st 6 months of ownership, cant remember the exact date: Vehicle appeared to restart as I turned left at a green light. 2nd incident: Vehicle appeared to restart itself whilst driving on highway (thankfully no traffic/other cars on the road at this time, but I was doing 70+mph at the time). Shortly after this incident, I called the local dealer to setup a service appointment about this issue. Service was unable to to replicate issue. They looked for whatever codes that might lead them to the source of the problem, but none found. Was told to monitor bring vehicle back in if it happened again. It's seems to look like some sort of electrical/computer glitch that causes the car to do this. It happens inconsistently (different driving conditons) and infrequently, but is a major safety issue.
