Within that volume, owners reported 11 crashes, 9 fires, 7 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 4/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2018 SPORTAGE is engine with 75 filings, followed by electrical system (25) and unknown or other (19). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 3 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 2 investigation files overlapping the 2018 SPORTAGE. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

My vehicle suffered from a catastrophic engine failure while driving on the highway. The vehicle stalled at highway speeds (55mph), during rush hour. Causing a near rear end collision. From this point on my vehicle was unable to reach speeds of 30 Mph. This failure is consistent with a defect in the Theta II engines that has been subject to recalls. The Theta II engine recall is under a soft recall. It is not known to the public unless it happens to the owners vehicle. This sudden stall at highway speeds jeopardized the safety of the driver (myself) and the people and vehicles behind the driver.
The contact owns a 2018 Kia Sportage. The contact stated that while driving at an undisclosed speed after an oil change was recently performed on the vehicle, the low oil pressure warning light illuminated with the message "Service Engine" displayed, and the vehicle made a dinging sound. The vehicle was taken to the dealer, where 5 quarts of oil were added to the engine; however, the failure recurred while driving the following day. The contact's son added 3 quarts of oil to the engine. The vehicle was taken to the dealer, where an oil consumption test was started. The contact returned to the dealer after 1,000 miles. The dealer informed the contact that two more 1,000 miles tests were required to complete the oil consumption test. The contact declined to pay the fee to complete the test and was advised to trade the vehicle in at the owner's expense. The contact stated that the vehicle was purchased from the dealer as a certified pre-owned vehicle. The vehicle was not diagnosed or repa

My 2018 Kia Sportage (2.4L Theta II GDI engine) suddenly triggered diagnostic trouble code P1326 (Knock Sensor Detection System â Detection of Excessive Connecting Rod Bearing Wear) and entered limp mode at 111,595 miles on Sep 13, 2025. The vehicle is now speed- and RPM-limited to protect the engine from catastrophic failure. This is the exact failure mode covered under the well-documented Hyundai/Kia Theta II engine defect that has led to thousands of engine seizures and, in some cases, vehicle fires. Kia implemented the Knock Sensor Detection System (KSDS) software update (Campaign SC200) on this VIN, yet the system has now correctly detected excessive connecting rod bearing wear. Despite the vehicle falling squarely within the class vehicles listed in the 2020â2023 Hyundai/Kia engine litigation settlement (In re: Hyundai and Kia Engine Litigation II), Kiaâs settlement VIN-check website [XXX] ) incorrectly states this VIN âhas not been matched with an eligible Class Vehicle
The contact owns a 2018 Kia Sportage. The contact received notifications of NHTSA Campaign Number: 22V703000 (Trailer Hitches) and 21V137000 (Service Brakes, Hydraulic); however, the contact was possibly charged for the recall repairs. The contact stated that while driving at various speeds, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The KSDS warning light was illuminated. In addition, the contact became aware of abnormal oil consumption. The contact stated that after restarting the vehicle, the failure reoccurred. The vehicle was taken to a local dealer, where it was diagnosed, and DTC: P0010 was retrieved. The vehicle was repaired at the owner's expense; however, the local dealer diagnosed the vehicle and determined that the camshaft needed to be replaced. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 150,000.

Due to excessive oil consumption and blow thru to catalytic converter, and burning of oil in the converter clogged up my catalytic converter as seen in pics causing exhaust fumes to enter cabin and engine not run properly. Driver or passenger must open windows to get fresh air. I had to have converter replaced. There is still periodic fumes that enter cabin even with new converter because engine is still consuming excessive oil . This should be addressed to and rectified through KIA corporation. Thanks
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 itâs like white. Then on the roof of that vehicle, thereâs 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.
The original factory engine is malfunctioning, causing excess oil consumption -- at or over one quart consumption per 1000 miles -- believed to be caused by fouled piston rings. It is a known defect for this and similar KIA engines. Issues and remedies outlined in KIA Technical Service Bulletin 222. The vehicle and engine are available for inspection upon request. Our safety and the safety of others is continuously at risk in the event of engine failure and/or vehicle breakdown in city or freeway traffic, and in our rural location. Safety is also a factor in the event of vehicle breakdown which would put vulnerable passengers (five year old granddaughter, etc.) in danger if such event occurred in traffic or during weather extremes. The oil consumption problem has been confirmed by Butler KIA. The engine was inspected by the manufacturer via Butler KIA only in the form of three 1000-mile oil consumption tests from May through October 2025. Dealership personnel began the first test
There has been High oil consumption after 100,000 miles and the low oil light has shown. It will burn more than a quart in less than 1,000 miles.
My vehicle make and model has been documented to have had engine issues which has caused car fires from the engine compartment from what has been documented this is my best guess.

The code P1326 keeps popping up on my dash board even after changing it that part out which is claimed to be the knock sensor.I researched it and it said something with the rod bearings and my mechanic personal mechanic had mentioned itâd be best to swap the engine, and told me about Kia recalls on certain make and model. My vehicle falls into the recall list of year and make and model⦠but my vin isnât on the recall list, yet it is doing the same exact thing that has been listed up for recall. I am concerned about my safety, engine stalls and looses power, how can I go about this?
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!

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 Kiaâs known engine defect. Kia Consumer Affairs (Case #25572677) has denied goodwill assistance despite this safety-related engine failure and prior diagnostic documentation.
