KIA Complaints

Electrical control unit car just shuts off in drive completely goes black no matter what within seconds even on freeway going 70 mph car tune off loss of control then starts back up very dangerous

Bought car in Nov 24. Noticed a popping sound as if a rock was hitting windshield. Nothing hit windshield. The popping sound was intermittent but went on for months. Finally in August 2025, I noticed a crack in upper side of drivers windshield. Next day crack got bigger. Called safelite to replace. Had to park car with cover over windshield since I couldn’t get an appointment right away. Had to rent a car. Windshield replaced. Popping continues, less frequently but it still pops. Took it to Burlington Kia and explained my issue. They could not replicate the popping sound.

Paint is bubbling and peeling off. Been to the dealership and they don’t seem to want to help. I have an extended warranty on the paint until 12/29/2025. They’re giving me the runaround.

The electrical system failed (dashboard warning light appeared while in park) and then a pop was heard (fuse bursting). Car could not safely drive. Dealer confirmed ICCU failed once checked at dealer. No prior warnings noticed and no issues charging with approved systems leading up to the failure.

The rear door of my KIA EV6 intermittently fails to open even when the vehicle is unlocked. The issue has been recorded on video and reported to an authorized KIA dealer, but it has not been repaired. A child safety seat is installed in the rear seat, and this defect creates a serious safety risk in an emergency where immediate access to the child is required. The vehicle is unsafe due to this defect.

My ICCU failed while I was driving and I lost power while in a light controlled intersection in Chicago. The screen turned off and I could not see my speedometer or any driving information. I luckily was able to roll to the side of the road and park the car. My car could not change gears, doors would not work, trying to jumpstart the 12V did not work.

The contact owns a 2018 Kia Sorento. The contact stated that upon starting the vehicle, there was heavy white smoke coming from the exhaust pipes. There was no warning light illuminated. Upon taking the vehicle to an independent mechanic for an oil change, the contact was informed that there was an oil leak coming from the engine. The contact had her son inspect the vehicle, and he discovered that oil was leaking onto the spark plugs in cylinder #1. The contact’s son diagnosed the vehicle with engine failure and recommended that the engine be replaced. The contact then stated that while driving 60 MPH, the vehicle started shaking with the check engine warning light illuminated. The contact pulled over and waited for approximately an hour before being able to restart the vehicle and drive to the destination. The vehicle was then taken to a dealer, where a diagnostic test was performed, and the dealer discovered several oil leaks in various cylinders. The vehicle remained with the dealer. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was unknown.

On 11/21/2025, while operating my vehicle, I experienced a critical engine failure. The engine failed a compression test, with readings as follows: Cylinder 1: 125 PSI Cylinder 2: 60 PSI Cylinder 3: 25 PSI Cylinder 4: 3 PSI As a result, the engine had no compression in multiple cylinders, preventing the vehicle from starting. The vehicle exhibited [smoke, stalling, or other observable symptoms]. This failure appears consistent with known issues in the Theta 2 GDI engines, including risk of engine failure or fire. I had not received notification of any required software updates or recalls relevant to this issue. Despite multiple attempts to resolve this with the dealer, including [dates of service attempts], the dealer refused to cover a replacement engine under warranty. Impact on Safety: The sudden engine failure rendered the vehicle inoperable and posed a significant safety risk due to the potential for stalling or fire while driving. Additional Notes: I am submitting this report to request that the NHTSA investigate this potential safety defect.

The contact works as an investigator for the Utah Motor Vehicle Enforcement Division. The contact was investigating a 2014 Kia Optima with a salvaged title and reported that the air bags failed to deploy in a front-end collision. The contact stated that the air bags may have been removed or the air bag sensors were disconnected. The contact stated that while the driver was driving at 30-35 MPH, the brake pedal was depressed but the brakes failed to stop the vehicle. The vehicle crashed into another vehicle. The air bags failed to deploy. No warning light was illuminated. The driver's face struck the steering wheel upon impact. The driver received medical attention. A police report was filed. The vehicle was towed to a tow yard, where the insurance company investigated the crash, but had not yet deemed the vehicle totaled. The manufacturer was not made aware of the failure. The failure mileage was unknown.

Tires are Douglas Touring, and Sceptor. Those options were not available. I bought a set of tires that belongs to two different brands. Three from Douglas/Goodyear tires and one is Sceptor all from Walmart. They are supposed to have 50000 miles and 45000 miles respectively. When I took for car service, two different service mechanics mentioned that two of the tires have already reached 2/32. Originally, two tires were bought in June 2023, third tire is July 2024, and fourth tire in Jan 2025. There was already an issue with a tire that led to replacement earlier this year. I even filed a set of NHTSA reports in this regard earlier this year in February 2025. Now, two tires have gone down to less than 7/32, and as stated above has reached 2/32. I even shared a picture of peeling tread that I noticed at the time of purchase. This repeating issue suggests high likelihood with quality concern with these tires. For that matter, suddenly, I was asked to change brake rotor and pads, while previous inspections did not suggest any such change. As you might know, poor tires can also impact the brake rotor and pads. Your support to address this issue quickly would be greatly appreciated.
