Kia Sportage electrical problems

2017 Kia Sportage while driving on the highway, the vehical starting losing power and shaking, it lost power and several unknown warning lights illuminated. The vehicle was towed to an independent mechanic, where it was diagnosed with engine failure and the engine needed to be replaced. The vehicle was not repaired. The vehicle was towed to the dealer, where the same diagnostic test information was provided. The Kia dealer said that the engine needed to be replaced, but since it was not the rod, but only the #4 cylinder it would not be under the extended warranty. The vehicle has not been repaired. The manufacturer was made aware of the failure and we were denied extended coverage. In addition to this, the electrical system has been failing and the windows would not roll up, this was fixed before the engine failure, but the drivers side door still does not unlock without the key. The failure mileage was approximately 112,000.

My Kia Sportage was stolen, however a couple of years ago I had the Kia Anti Theft Logic software updated on the car. I’ve been told that although it does not prevent anyone from breaking in, they should not have been able to move the car. Prior to this, the engine is running on 3 cylinders instead of 4 which has caused major issues with the car burning oil rapidly.

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

The car dies after parking for less than an hour, I have to press the battery reset button every time I get into it which also sets the alarm off probably annoying all my neighbors. There’s no accessories plugged in. The dealer is charging me $270 dollars to do a BMS update but I have seen recalls for this online that say it should be covered for free.

As I am driving, does not matter speed or weather, the instrument cluster screen will do a "System Check" as if the vehicle is being started. The screen will go blank for about 5 seconds and then will reappear. If the vehicle is in cruise control, that will disengage and the vehicle will slow down and I have to catch it and keep speed up. This does not happen every day and has happened at different intervals of 6 days between incidents and up to 15 days. Occurred on: June 9, 2025; June 17, 2025; (vehicle in shop to be looked at June 23rd through August 5th); August 9, 2025, August 14, 2025; September 6, 2025, September 18, 2025; and October 2, 2025.

The contact owns a 2021 Kia Sportage. The contact stated that her mother was driving at an undisclosed speed on the freeway and had stopped on the shoulder of the road to access the navigation system. The contact stated that after the driver shifted to park(P), the driver noticed smoke. The contact's grand-mother who was also occupying the vehicle advised the driver that the smoke was coming from underneath the hood. The driver then noticed that smoke and flames were coming from underneath the hood of the vehicle. The contact stated that the vehicle burned to the ground. The fire department was called to the scene and extinguished the fire. It was unknown whether a fire department report and a police report were filed. The vehicle was towed to an unknown location and was in the process of being inspected by the insurance company adjuster. Both the contact's mother and grand-mother later received medical assistance for smoke inhalation. The cause of the fire was not determined. The manufacturer and local dealer were not yet contacted. The failure mileage was approximately 70,000.

I leased my 2020 Kia Sportage LX in August 2019 and purchased the Vehicle after the lease. In April 2025, the Vehicle started emitting a strong gas smell after filling. Often, the pump would stop short around 8-10 gals instead of the usual 13-14 gals. I attributed both to perhaps cheap gas and faulty pumps. On September 23, 2025, I went to the dealership to check the gas odor and possible gas leakage and ticking engine noise. I ended up having to replace the entire fuel tank. The car is now 6 years old and, of course, out of its 5-year warranty. The report indicates that the leak was from the top of the tank and in the cabin; therefore, nothing was caused by normal wear or damage. Upon searching, I found that in January of 2019, previous years were recalled to replace the fuel tank due to similar issues (Gas Tank Recall # SC172). Some of these models had recalls for the KSDS as well, and my vehicle had been recalled and repaired. My concern is that this is my 3rd Kia and 6th car total in life. Never have I had to replace a gas tank. I firmly believe some of these 2020 vehicles were built at the end of 2018 with the same parts in the 2019 recall; however were missed due to recall time and manufacturing rollouts.

In 2018 my I was driving home when it just shut off and wouldn’t start. Smelled like burning and had it towed to my house and had several mechanics look at it and couldn’t find the problem then as it was parked on day it started to smoke and the engine was burning I put out the fire and then a couple months later I got the recall information the car was a total loss and could t be repaired and no compemsation was sent to me. Ive contacted the class action suit and they were very vague with the information. I waited and the car eventually disappeared in which I thought the Kia company picked it up. I still have t hear word from anyone and my car is no where to be found and I would like to be reimbursed for the car since it was paid off

This is an issue of nonconformity according the Florida Lemon Law: "Florida's Lemon Law protects consumers who buy or lease new or demonstrator vehicles with persistent, significant defects, known as nonconformities, within the first 24 months of ownership." My March 2025 leased Kia Sportage was sitting for about an hour. I turned it on and the all the dash warning lights stayed on, hot air blew (no AC), and I couldn't shift out of Park. I tried turning it off/on twice, with a few minutes in between attempts, and on the second attempt only the Check Engine light stayed on, cold AC blew, and I could shift. I drove 3.5 miles home. About an hour went by, I started it again and the Check Engine Light was still on. I drove it 2.5 miles to the dealership, turned it off, and minutes later they started it to move it but the Check Engine light had gone off. They said another car almost the same mileage (4040miles) had the same issue and because the light wasn't on, the scan showed nothing. They told me to return if it happens again and not to shut it off because the Kia Dealer could not duplicate or reproduce the concern at that time. My vehicle is available for inspection and diagnosis, but the dealer said a computer scan wouldn't show anything. Something is definitely not okay and I do not feel safe. Although this incident was while traveling 20-40mph, I travel at high speeds on the highway during the week for work, and am very concerned for my safety.
