KIA Complaints

Re: Driver Safety Downgrade Stemming from Recent Software Update Complicating Tire Pressure Display Accessibility I am writing as the owner of a 2025 Kia Niro HEV to express my concerns regarding a recent software update that altered how tire pressure information is accessed on the instrument cluster. Prior to the update, tire pressures were available through the steering wheel page button, allowing drivers to view this safety-critical information with a single press and a quick glance. After the update, the tire pressure screen was removed from the page sequence and relocated into a deeper Vehicle Information submenu that requires multiple button presses and menu navigation. This change has created a significant safety issue. Tire pressure can only be displayed while the vehicle is in motion, yet the update now requires the driver to divert attention from the road to navigate several screens in order to access it. This is a clear regression from a human factors and safety standpoint. The previous method was intuitive, efficient and aligned with safe driving practices. The new method increases cognitive load and driver distraction at precisely the moment when attention should remain on the road. I respectfully request that Kia reevaluate this change and consider restoring tire pressure visibility to the steering wheel page button or another single-action, high-visibility location. Tire pressure is not a secondary diagnostic item; it is essential real-time safety information that should remain immediately accessible. I appreciate Kia’s commitment to innovation, but updates that alter established safety workflows should be communicated clearly and designed to not be at odds with a driver's attention to the road. I hope Kia will take this feedback seriously and consider adjustments in future software releases. Thank you for your attention to this matter.

The engine consumes a massive amount of oil to where I have to check my oil constantly and refill as often as weekly. This can pose a risk to myself and others due to the engine failing while I am driving. I am sure other issues can come from an engine running out of soil that I’m not aware of.

My car went into limp mode on the high way due to a faulty knock sensor. my car decelerated rapidly, which could have put me and others around me at risk. I had to repair this problem on my own even though other cars similar to my make and model have had the same issue.

The contact owns a 2013 Kia Soul. The contact stated that while the vehicle was parked and attempting to start the vehicle, there was a popping and knocking sound coming from the steering wheel. No warning light was illuminated. A dealer was contacted. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 80,000.

My 2020 Kia sportage spontaneously caught fire. It started smoking about 1/3 mile from my destination. There were no dash lights on and the temperature gauge was not elevated and was below half so it wasn’t the engine overheating. I pulled into the parking lot and shut off the car and the smoke then increased and turned darker rapidly and the car caught fire and was quickly engulfed and then there were several explosions. The car was a complete loss. Had I taken any more time to figure out the smoke I would have been a casualty.

The contact owns a 2025 Kia Sorento. The contact stated that while driving approximately 75 MPH, the vehicle lost automotive power and failed to exceed 30 MPH. The contact pulled over to the side of the road to avoid other vehicles. No warning lights were illuminated. The vehicle was towed to a dealer to be diagnosed; however, the cause of the failure was not yet determined. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 16,386.

My rear backup camera stopped working this year it's either a black screen or blinking screen no video will play. When I first started the video was foggy like moisture was in the camera and now it shows nothing. Other Kia sorento's my same model year have had a recall for the backup camera but mine is not on the recall list for some reason.

The contact owns a 2014 Kia Optima. The contact stated that while driving 60 MPH, the vehicle unexpectedly stopped. There were no warning lights illuminated. The contact used a scanner and retrieved a code for failure with the knock sensor detection system and glow plug relay. The vehicle was towed to the local dealer, where it was diagnosed and determined that the engine had seized. The vehicle was not repaired. The manufacturer was contacted and opened a case. There was a question about the ownership of the vehicle. The warranty was denied because the vehicle was not being purchased from the dealer. The contact provided the title to show ownership. The failure mileage was approximately 167,000.

The engine consumes excessive oil due to the known Theta II piston oil control ring defect that the manufacturer documents in its own Technical Service Bulletin ENG222, covering this engine family across model years 2011 to 2024. The vehicle loses over one quart of oil per 1,000 miles with no external leak and no oil pressure warning. The manufacturer's authorized dealer completed the entire TSB ENG222 diagnostic protocol, which is itself a controlled test designed to isolate cause. The engine was sealed, and after 1,080 miles it was 1.5 quarts low. The dealer then performed the TSB's combustion chamber cleaning. After that repair, over 1,149 miles, the engine was 1.4 quarts low. The cleaning had virtually no effect on the consumption rate. Because the protocol sealed the engine and cleaned the combustion chambers and the consumption rate remained unchanged, the protocol itself mechanically excludes maintenance as the cause and isolates the failure to the internal piston rings. This is the exact defect TSB ENG222 was created to diagnose and repair. The defect has been reproduced and confirmed by the manufacturer's own authorized dealer through this protocol, and the vehicle is available for inspection upon request. Under the TSB, these results qualify the engine for replacement. The manufacturer nonetheless denied the engine replacement, citing a lack of oil change receipts rather than any technical evidence of neglect, despite its own diagnostic protocol having already ruled out maintenance as the cause. Safety concern: an engine consuming oil at this rate risks sudden loss of oil pressure and engine failure while driving, which can cause a stall or loss of power in traffic.

The contact owned a 2014 Kia Soul. The contact stated that while stopped at a traffic light, the contact became aware of a burning rubber odor and observed grey and brown smoke coming from underneath the front end of the vehicle. The contact stated that a fire had started underneath the front of the vehicle. The local Fire Department arrived on scene and extinguished the fire. A fire report was not filed. A Police report was filed. The vehicle was deemed a total loss. While exiting the vehicle, the vehicle continued rolling and the rear driver’s side tire ran over both feet. The contact had two severely bruised feet; however, medical assistance was not sought. The vehicle was not towed or taken to a dealer or an independent mechanic to be inspected. The dealer was not notified of the failure. The manufacturer was not notified of the failure. The failure mileage was 107,000.
