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 INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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
Two issues with my vehicle: 1. When driving and stopped at a red light, the stop/start technology will engage, turning off my engine. Upon the light turning green again, my foot comes off the brake to hit the acceleration but the entire dashboard/electrical system restarts like the car has just been turned on. It has done this mid-driving (foot on the acceleration) as well; killing the entire electrical system. No warning lights or messages appear. 2. When driving longer distances (20+ miles), sometimes the vehicle engine will not turn off. I drove a distance of about 20 miles; got to the destination, parked the car and hit the start/stop button to turn off the engine. The entire interior electrical/dash was off but when I hopped out of the vehicle, the engine was still running. I have to re-enter the vehicle and turn it back on and off just to get the engine to turn off. No warning lights or signals appear. The dealership won't fix my issues; says they can't recreate the problems but I do have video evidence that the problems exist. It has happened periodically since I purchased my vehicle, a 2021 Seltos SX, in March of 2020.
Car stalled when at complete stop (at lights or stop signs) The auto restart feature seems to fail. Then it progressed to stuttering while driving and unable to drive above certain speeds (more than 40 mph). Service engine light on. Code by dealer P0017.
5/18/23 My car shut off with the stop/go feature and would not turn back on. Was able to start once I removed the key and tried again after a few minutes. This again happened to me once I got to a gas station resulting in the same issue today 5/19/23
When driving the vehicle the motor will randomly shut off. This is a safety hazard and has been happening more and more. I thought it was supposed to do this but only when stopped. It now is doing it while driving and I have almost been rear ended 3 times now. The car is not drivable.
My 2021 Kia Seltos shut off while I was driving it. This happened once in July 2021, I was at a stop sign and I attributed it to not driving it in a while and the extreme summer heat. But on January 31st, I had turned my car on, I let it “warm up” and then I started to drive. To my surprise, as I was driving my car shut off. It first felt like the gas pedal was hardly working then the car began to slow down and I had no control over the acceleration or breaks. Then, the check engine light, battery light, and oil light all appeared on my dashboard and the car came to a complete stop. And all functions on the car were not functioning. Fortunately, no other cars were around and I wasn’t injured. I was able to restart my car and drive back to a driveway with the engine sounding louder than normal and the only the check engine light on. From there, Kia towed my car to the dealership, ran a diagnostic check on the engine, checked the sparks plugs, drove it 25 miles. Since the problem didn’t occur while they had it, I have been informed “nothing is wrong with my car”. I called Kia customer service and was informed that despite the similar claims on this website, no recall or issue had been formally filed for kia to take care of. I questioned what the next steps would be and as of now I am left to continue to drive a car that shut off on me.
HVAC BLOWER WOULD NOT BLOW. DEALER FOUND MELTED RELAYS. ONE WEEK AFTER REPLACING THE ENTIRE ENGINE WIRING HARNESS I STARTED TO GET A BURNT ELECTRICAL SMELL THROUGH THE VENTS. I LOOKED IN THE ENGINE FUSE BOX AND THERE WERE MELTED RELAYS AGAIN.
