KIA Complaints

The contact owns a 2020 Kia Soul. The contact stated that the vehicle was repaired under Kia Recall: SC209; however, the repair failed to prevent the failure. The contact stated that while driving at various speeds, the contact became aware of a n excessive oil consumption. No warning light was illuminated. The vehicle was diagnosed by an independent mechanic, and it was determined that the engine was consuming an excessive amount of engine oil; however, the cause of the failure was unknown. The local dealer was contacted; however, the vehicle was not diagnosed or repaired due to the cost. The contact stated that oil was being added approximately every 2 days. The manufacturer was made aware of the failure. The failure mileage was approximately 95,000.

I had my oil changed in Dec. 2025. I drove 1000+ miles w/no issue. Engine suddenly seized w/no engine light warning. Oil dumped all at once. Kia refuses to cover under warranty. THIS HAPPENED TO MY CAR: NTSA announced it had launched an investigation into Hyundai Motor Company and Kia Motor Company for problems with their oil pans and oil drain plugs... consumers have filed complaints their engine’s oil drain plug falls out, causing all the oil to drain out of their engine while driving. In multiple tests the oil drain plug was tightened according to factory torque specifications and the tightening was well documented. Yet, testing shows in multiple cases that while driving, the oil drain plug falls within a few thousand miles after the service. In those cases, the crankcase drained completely. The Hyundai and Kia drain plug falls out due to inferior oil pan material and the drain plug gasket. The testing and investigations appear to show that the oil drain plans are made with THIN METAL AND THE DRAIN PLUG MOUNTING IS POORLY REINFORCED. In addition, the oil pan is coated with a thick paint coating the bonds the gasket to the pan, so the gasket does not come off when the drain plug is removed. That gasket issue alone is not why the oil drain plug falls out, but it is a factor in the chain of events. The oil pan is the biggest problem Apparently, the thin metal, along with engine vibrations and expansion/contraction tend to loosen the drain plug without any other intervention. NHTSA is investigating this as a factory defect ... The problem is two-fold. First, even if the repair shop properly torques the drain plug, the oil drain plug falls out on its own. The customer then blames the shop for shoddy workmanship. Second, Hyundai and Kia dealers are telling customers that servicing their vehicle at an aftermarket shop automatically voids their factory warranty. This is totally false & actually illegal under the terms of the Magnuson-Moss Warranty Act.

I tried months ago to have my 2011 KIA Sorento LX 3.5L v6 AWD to get the recalls fixed @ KIA in Yorkville,New York. They said they couldn't fix the recalls that were on the vehicle because supposedly the suspension is unsafe. But I already had the vehicle on a lift 4 times since,6 times total to get parts installed from my mechanic. If it was so unsafe,how could my mechanic lift the vehicle without any issues. I needed to get the underbody sprayed to stop rust and corrosion but KIA refused me.The recall for the ABS module needed fixing,they refused me. Having problems with the ABS and my subframe/crossmember broke. I feel the spray could've helped

Unjustified Denial of Engine Warranty Coverage - 2015 Kia Sportage "I am filing this complaint because Kia is denying warranty coverage for a known engine defect (rod bearing failure in the Theta II GDI engine) on my 2015 Kia Sportage. The manufacturer’s denial is based on the claim that I did not perform the KSDS (Knock Sensor Detection System) software update in previous years. However, I have officially performed this update at an authorized Kia dealership (Hendrick Kia of Cary) on April 17, 2026. Despite my vehicle now fully complying with the recall requirements, Kia continues to deny the warranty claim by retroactively applying a 'missed update' penalty. This is a clear attempt to evade their obligations under the class-action settlement regarding this engine defect. The manufacturer is holding the current owner responsible for maintenance history they cannot control, even though the vehicle is now technically compliant. I request that the NHTSA investigate this practice, as it prevents consumers from accessing the safety-related warranty protections they are entitled to." Tips for your submission:

The contact owns a 2022 Kia Seltos. The contact stated that the check engine warning light illuminated, and the vehicle stalled. The vehicle was able to be restarted, but the vehicle was jerking while driving. The vehicle was taken to a dealer, but was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 84,000.

The contact owns a 2023 Kia Niro. The contact stated that while driving at 25 MPH, the vehicle independently accelerated. The contact constantly depressed the brake pedal to stop the vehicle. The contact was able to coast the vehicle to the residence while depressing the brake pedal to prevent the unintended acceleration. Neither a dealer nor an independent mechanic was contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 11,000.

I lease a 2025 Kia Telluride. This vehicle has experienced three serious safety failures around the one year mark, all with young children in the car. Incident 1: accelerator failure and inability to shift gears approaching a freeway on-ramp — transmission was replaced. Incident 2: complete loss of steering control, brakes would not fully engage, and vehicle moved without accelerator input — dealership found nothing wrong and returned the vehicle with no explanation. Incident 3: accelerator failure and failure to shift in active traffic — another vehicle nearly rear-ended us — dealership said there was a belt loose that can cause issues sometimes. Kia Financial Services, as legal owner, has refused early lease termination despite these documented safety failures. The root cause of a loss-of-steering and brake-failure event has never been identified.

My 2018 Kia Soul with the 2.0L Nu GDI engine is experiencing severe oil consumption of approximately 1 quart every 300–400 miles. The engine and lubrication system are available for inspection upon request. My check engine light is currently on. The dealer performed several recalls on the vehicle, including PI2107 (KSDS), SC226, and CS2311A, but refused to perform the required oil-consumption test described in TSB ENG 222 (Rev 8). The service technician stated that because the oil-consumption test is “not on the VIN,” they would not perform it under warranty. I was told I could pay $250 out of pocket for the test, but that even if the test confirmed a defect, the dealership would not cover any repairs. I was also told to “run the car until the motor seizes up” before they would help. This instruction is unsafe and contradicts Kia’s own safety systems, including KSDS, which is specifically designed to prevent engine seizure while driving. Driving a vehicle with rapid oil loss until the engine seizes can cause sudden loss of power, loss of steering assist, and a crash hazard. The problem is ongoing and repeatable, but the dealer refused to diagnose it properly. I am reporting this because the dealership refused to perform required safety-related diagnostics and instructed me to operate the vehicle until catastrophic engine failure occurs, creating a significant safety hazard for me and other motorists.

The Integrated Charging Control Unit (ICCU) failed twice within four weeks. The first failure occurred in March 2026 and was repaired under recall SC327 with a replacement ICCU and fuse. The second failure occurred April 7, 2026, approximately 12 days after pickup. Symptoms: Vehicle failed to charge overnight on Level 1 and Level 2 circuits despite being plugged in. Later that day, while driving, a “Check Electrical System” warning appeared on the dashboard followed by sudden loss of power and acceleration. Vehicle fluctuated between 25-45 mph and could not maintain speed. Vehicle was driven approximately 2.2 miles to the dealership under its own power after warning onset. Safety risk: Sudden loss of power and acceleration while driving created a hazardous condition for myself. Dealer confirmation: The authorized Kia dealer confirmed a DTC for battery overheating and acknowledged the ICCU coolant was not fully topped off after the first replacement, suggesting the recall remedy was incompletely performed. The vehicle has remained at the dealer unrepaired since April 10, 2026. Component available for inspection: Yes, vehicle is currently at the dealership. Recall remedy concern: The SC327 recall remedy did not resolve the ICCU failure. A second failure occurred within two weeks of the repair. The dealer’s subsequent diagnosis of owner-caused undercarriage battery damage is contradicted by their own signed inspection report documenting all undercarriage items as passed with no damage noted

At 7,100 miles the transmission failed requiring a new transmission replacement after one year. At 16,636 miles (2years into the lease) the new transmission also failed, and the car is in the garage getting another transmission replacement after.
