KIA Complaints

Driving 40 mph coming around a bend. There was a car stopped about to rear off to the left and when coming up around the turn I saw and tried to stop. I was about two car lengths behind the car when I pressed the brake down and I pushed it all the way down and nothing happened. It was grinding and shaky when pressing it down. Not tight or anything. I feel like I normally would have that tension right away to be able to stop. There was no warning or anything and the car always has warnings when something is close.

My 2017 Kia Sportage with approximately 98,000 miles suddenly started using oil at times. It would go for several trips with everything fine and then it would be a quart low. I continued to drive it and check the oil before every trip. At approximately 106,000 miles, I suddenly lost engine power, a small puff of black smoke from the exhaust, and the check engine light came on. I crippled it home after checking all fluids - they were fine. I trailered the car to my mechanic and after diagnosing it, he stated the #1 cylinder had no compression. I brought it home and checked online to find out that this seemed to be a common occurrence with the Sportage. To double check, I took the car to a second mechanic to get the same results except he provided more detail. Compression on #1 Cylinder 0, #2 was 140, #3 145, #4 140. He stated the compression should be above 175. My safety issue was I could have been stranded on I49 and if this had happened at night, I may not have been able to get it home. I took the vehicle to Crain Kia, Fayetteville, AR. when the first Check Engine Light came on and they stated it was shown as low engine oil even though it had oil in the engine and that it showed low compression on Cylinder 4. I now have a vehicle with 106,048 miles that without major engine repairs is worthless to me.

In April, 2025, my vehicle's engine power was significantly reduced while on the highway. I could not keep pace with traffic. My mechanic said there were recalls for the turbo engine but my car was not included. I paid forbthe part and repair. Less than a year later and the car began burning a lot of oil very fast. I add oil weekly. The car has again been losing power and there is still no recall for my car's engine. There is burning and smoke coming from the engine because of an engine oil leak Jiffy Lube detected yesterday, Mar h 11, 2026. The problem began at around 65k miles and now has 88k miles.

Today, my young daughter pressed the button on the inside of the door to close the sliding door. Her hand was still in the way and the door did not stop. Part of her hand was completely closed in the door and she screamed and cried in excruciating pain. Right away I noticed bruising and took her to the ER for an X-ray. Since she is so young, her bones are very pliable and thank goodness the X-ray showed no fracture, just bruising and swelling. The sliding door has previously not stopped for my older daughters as well. This is a major safety issue.

I am submitting this complaint regarding the failure of the Kia Connect telematics system and the cessation of critical navigation support for my vehicle. Despite opening a formal support case with Kia (Ticket #25923650), the following issues remain unresolved: Loss of Trip History (Since January 2026): The Trip History feature within the Kia Connect suite has been completely non-functional since January 2026. This prevents the tracking of vehicle usage, mileage, and driving behavior data, which are core features of the paid subscription service. Failure of Connected Routing & Software Obsolescence: The "Connected Routing" feature is no longer operational. Kia support has stated this is due to the vehicle requiring a navigation update; however, Kia has ceased providing all navigation and software updates for this model as of April 2025. Safety Concern: The lack of software support and the failure of "Connected Routing" forces the vehicle to rely on navigation data that is nearly a year out of date. This creates a safety risk when the vehicle provides incorrect guidance on one-way streets, closed roads, or altered traffic patterns. Furthermore, the persistent failure of these telematics services raises serious concerns about the reliability of the vehicle's emergency communication systems, such as Automatic Collision Notification and the SOS Emergency Assistance button, which utilize the same underlying cellular module and software framework. Corrective Action Requested: I am seeking a mandatory software update from Kia that restores full functionality to the Kia Connect suite (specifically Trip History and Connected Routing) or a final navigation map update to ensure the vehicle’s guidance systems remain safe and accurate for the remainder of the service's lifecycle.

I made a turn onto a highway. I got up to 45 mph after my turn and my car stalled. It felt like a was reared ended, my car came to just about a complete stop. It then began to shake and would not accelerate past 5mph to get me over to the side of the road. The check engine light came on. On 2/28/2026 my engine came on, I took it to Kia and they replaced my spark plugs, I got my vehicle back on 3/10/2026. At the beginning on 2026, Kia had my car for over a month for the same engine issues but said nothing is wrong with the vehicle. Back in December 2024 I had this exact issue of the car jolting and stalling. Kia said it was the transmission. I paid to have that replaced but it seems the vehicle is still having all of the same issues. My life was put at risk driving this 2021 Kia Seltos. I am very lucky that the cars around me were paying attention and did not crash into my car that came to a complete stop with vehicles going 65+ around me. Others lives could have been at risk had they crashed into my car. My car is once again back at Kia, with the engine light on again.
