Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

The vehicle suffered a primary connecting rod bearing failure covered under the Theta II class action warranty campaign. A brand-new warranty engine long-block was installed by an authorized dealership. Immediately upon vehicle pickup, the brand-new engine began exhibiting an un-metered acceleration defect. While stationary and idling in Park (P), the engine aggressively revs on its own without any operator input on the gas pedal. This malfunction caused the vehicle to violently surge and physically lurch forward several inches while in Park. This un-metered acceleration is an active, unpredictable driving hazard both in parking environments and in traffic, posing an immediate risk of a collision or pedestrian injury. The manufacturer has been notified but has failed to transmit a diagnostic pre-authorization to an alternative service center to safely inspect this powertrain hazard.

Shortly after driving away, before reaching a highway on-ramp, I noticed smoke coming from the vehicle. I turned around and returned to the location. By the time I arrived, the vehicle was emitting black smoke, and shortly after, it was fully engulfed in fire before I could retrieve a fire extinguisher. Vehicle has a documented history of a known manufacturer recall related to an electrical/HECU component and a separate high-pressure fuel pipe recall, both reportedly remedied prior to this incident

The oil was leaking somewhere not on the motor not under the car not blowing black smoke. I kept adding oil to it. No oil light. I was told not to park between 2 houses or in my garage it could catch on fire. I took it in several times and they did all kinds of stuff motor wash knock sensor was replaced wiring harness was corroded was slipping out of gear and other issues. And now it doesn't run because of the motor issue and they refused to fix it because I didn't have oil change receipts they are the ones that took care of that there was no oil to change I kept adding it. I have all of the detailed work invoices of what they did to it. I've been without a car for a year now they said it's not under warranty my car has several of the recalls. They wouldn't do all of the stuff they did if it wasn't necessary and trying to locate the problem.

Purchased my Kia on the XXX then on the XXX, My engine light came on and my car went into Safety Mode . I at once took it to Auto Zone and their test came back with P1326 Knock signal range / performance. I then looked it up and found that a recall was put out quite a while back called an [XXX] # took my car to Kia Dealership in [XXX]. They said I could bring it in that was on the XXX and if an appointment came open they would check but they did not have an opening til the 14th which was today and I was told it would be next week . Could someone please send me updated information concerning the 2018 Kia Sportage and the Knock Sensor [XXX] [XXX] [XXX] [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

NHTSA ID 11757330 · filed Aug 16, 2026

I received a voluntary emissions update letter from kia, and although it was voluntary, the letter said failure to update could be considered lack of maintenance. The update was performed on XXX at Dorsch Ford/Kia in [XXX]. The vehicle ran poorly from that day forward. I gave it a couple of weeks to insure that the system could learn my driving habits. I then went to the Dorsch service department to report my issues. The service writer {Andy} said he hadn't heard of any issues with the update. I had him log in my issues to have a record that I complained. I returned several more times and talked to other service writers who told me that if they would check the vehicle and found nothing that I would have to pay service fees. the vehicle jerks and up/downshifts frequently and almost stalls sometimes when accelerating from a stoplight. It will lung periodically when navigating a parking lot at low speeds. It frequently searches for a different gear in traffic. To be clear, my car ran perfectly before this update. I asked them to put the previous tune back into the car but they said they can't do that. The car runs fine sometimes but the uncertainty of the jerking and shifting at improper times makes it dangerous to drive. Also almost stalling at an intersection is very dangerous too. I doubt that I am the only one to have this problem. Please help in any way you can to get this fixed without me having to spend money to correct a factory/dealer initiated problem Thank you for all your help.

My 2018 Kia Sportage (VIN [XXX] ) experienced complete engine failure due to low compression/internal combustion chamber failure. The vehicle lost power while driving on Sept 30, 2025, and had to be towed to [XXX] Kia in Dayton, OH. This same dealership previously performed an oil retention test in Aug 2024 which failed, identifying a defective engine. Kia was aware of the issue but declined to replace the engine at that time. The failure pattern matches Kia’s known engine defect. Kia Consumer Affairs (Case #25572677) has denied goodwill assistance despite this safety-related engine failure and prior diagnostic documentation.

My car was stolen from the Kia challenge

NHTSA ID 11489673 · filed Oct 17, 2022

This Kia Sportage's alarm system does not go off when the passenger front window is broken. My car was broken into and the youth stripped the steering column and was able to start my car without needing the key nor having the key within the vehicle. This is a security issue and allows the vehicles to be easily stolen. These safety issues should be address and fixed immediately by Kia. The federal government should also hold Kia responsible for the spike in stolen vehicles across the U.S. seeing they know about the issue but have done nothing to fix it. The vehicle was then crashed and left running by the youth. I have included the estimate from Progressive to get it fixed.

This vehicle has a safety issue with the headlights. Basically, the low beams for both, driver and passenger sides are not functioning at all. Several diagnostic have been done to repair the existing issue such as replacing new light bulbs, new OEM turn signal switch, replacing whole new headlight assembly for both driver/ passenger sides, checking the relay, replacing new fuses, though, the issue still exists to date and the vehicle is undrivable in the dark. On a side not, only high beam works and turn signals, that is basically it. Several auto service centers have advised me to submit a report as a safety issues since all options have been exhausted. With that said, this safety issue concerning headlight should be addressed with the manufacturer. Thank you for taking this matter seriously!

I purchased a 2018 Kia Sportage and ever since the last few years the paint is starting to come off of this vehicle. I do not go through any type of car wash. I washed it at home. It is getting worse and worse than certain spots, I do not want any monetary for this I would just appreciate getting what I should have, which is fresh paint that last. The paint in the front bumper underneath the hood area is all coming off and it’s like white. Then on the roof of that vehicle, there’s white spots of the clearcoat actually coming off the whole vehicle. If you look also at my hood of the vehicle, you can see spots as well.

Driving down interstate, mid-morning, and my front sunroof imploded. VERY loud, like a bomb or gunshot. Shattered glass everywhere, all over myself and my car. I jerked, almost hitting a vehicle to my left. Correcting, and almost got hit by an 18 wheeler. Made it over, got off Interstate, was disoriented, ran a stop sign I think. Was the absolute worst sound.
