KIA Complaints

After getting recall work done last year regarding SC336 my sensor went off and now my car needs a new engine due to defective heat-treated Piston oil rings causing Catastrophic failure. Kia is declining responsibly because of lack of enough oil changes. They have not proved this failure was from neglect.

I own a 2014 Kia Soul 2.0L GDI that consumes approximately one quart of engine oil every 1,500 miles. The engine oil became dangerously low between oil changes without any warning indicator. The vehicle has also experienced reduced engine performance, declining fuel economy, and previously displayed a P0420 catalytic converter efficiency fault code. Replacing the PCV valve did not improve the condition. An overnight piston soak temporarily reduced the oil consumption, but the problem returned, suggesting carbon-related engine deposits. Kia has acknowledged that catalytic converter damage can create a safety hazard in certain 2012–2016 Kia Soul models equipped with the 1.6L GDI engine, and the NHTSA has issued a recall thereof (see "SC176 – 2012-2016 MY KIA SOUL ENGINE CONTROL UNIT (ECU) LOGIC UPGRADE SAFETY RECALL CAMPAIGN"). My vehicle is equipped with the 2.0L GDI engine and exhibits similar catalyst- and oil-consumption-related symptoms, but Kia declined assistance because my VIN is not included in the campaign. I am submitting this complaint because excessive oil consumption can allow engine oil to become dangerously low without warning, increasing the risk of engine damage or loss of power while driving. I request that NHTSA evaluate whether similar conditions are occurring in 2014 Kia Soul 2.0L vehicles.

My 2024 Kia Seltos (leased, approximately 19,800 miles) received an over-the-air (OTA) software update on [07/03/2026]. The vehicle's screen prompted me to approve the update and stated it would complete with the ignition off. I approved it and exited the vehicle as instructed by Kia's on-screen directions and owner's manual. Immediately after this update, the vehicle developed an intermittent no-start condition, and the 12V battery went completely flat, accompanied by an ESC (Electronic Stability Control) warning. The vehicle had no electrical or starting problems of any kind before the update. The vehicle was disabled and could not be started without a jump start, which is a safety concern — this could strand a driver in an unsafe location or in extreme weather. The dealer (Car Pros Kia Glendale, RO #531279, dated 07/25/2026) performed a full system scan, found no DTCs, and confirmed the 12V battery failed testing. The dealer's repair order documents the customer complaint as "intermittent no start condition and battery went completely flat after the software update." The battery was replaced at my expense. The vehicle's software version after the update was NNK-02-0118 (previous resident version NNK-02-0108). Kia America has acknowledged partial responsibility by approving a 50% goodwill reimbursement. I am reporting this because a manufacturer-initiated OTA update that discharges the battery and disables the vehicle is a safety defect that may affect other vehicles.

The contact owns a 2019 Kia Niro. The contact stated that while driving 65 MPH, the brake pedal was depressed; however, the vehicle failed to stop as needed. The contact pulled over to the shoulder of the roadway and the parking brake was engaged to keep the vehicle from moving. The message "Stop the Vehicle and Check Regenerative Brakes" was displayed. The failure was a recurring failure. The vehicle was towed, and the dealer was contacted; however, the vehicle was not diagnosed or repaired because the dealer was unable to duplicate the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 93,000.

The contact owns a 2022 Kia Carnival. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 21V908000 (Latches/Locks/Linkages, Structure); however, the failure persisted. The contact stated that the rear passenger’s side power sliding door failed to latch securely. The contact used force while pushing the rear passenger’s side sliding door from the outside to latch the sliding door properly. The dealer was made aware of the failure and informed the contact that it was unrelated to the recall repair. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000.

Air bag did not deploy, yes High Risk Yes Yes No Hit a street sign. Went through radiator, bent frame in front on passenger side, busted windshield, punctured roof. Car is totaled

The contact owns a 2026 Kia Sportage equipped with Kumho Tires, Tire Line: Crugen HP71, Tire Size: 235/60/R18, DOT Number: 1K2CMYA8E . While the contact’s daughter was driving approximately 75 MPH, the vehicle suddenly started shaking violently and vibrated abnormally, causing the driver to almost lose control of the steering wheel. The driver regained control of the steering wheel and parked the vehicle. The Police and a towing service was called to the scene. Upon inspection, it was discovered that the front passenger’s side tire had tread separation at the center of the tire, causing the center rim of the wheel to be exposed and caused damages to the wheel well and fender. The vehicle was later towed to the residence. The cause of the failure was not yet determined. The vehicle manufacturer and rental car company were notified of the failure. The tire manufacturer was not yet contacted. The failure mileage was 3,900.

"The vehicle has twice suffered a sudden, catastrophic loss of motive power at highway speeds (approx. 70 MPH) on the interstate, forcing the driver to coast across active traffic to the shoulder without engine pull. The engine revs freely in 'Drive' but the transmission fails to engage any gears. No dashboard warning lights, check engine lights, or diagnostic trouble codes are triggered during or after the failure. The failure resets temporarily only after cycling the ignition key off and on.The vehicle previously had Safety Recall SC250 (8-speed Electric Oil Pump) performed by an authorized dealer, but the software flash completely failed to prevent this catastrophic hydraulic/electronic failure mode or provide the federally mandated dashboard warning countdown. The vehicle is entirely unsafe to drive,

While I was driving, my 3.3 V6 engine on my 2016 Kia Sorento seized up with no warning. There is no visible oil on the dip stick, although I have changed my oil routinely. There has never been visible oil outside of the engine or on the ground. I never had any warning light come on. I believe the engine burns an extreme amount of oil, which is putting people in a dangerous situation and financial hardship.

My 2022 Kia seltos with 47669 miles does while while driving. It DID NOT make a noise or shake. The engine light and oils light come on and the car dies. I have maintained regular oil changes and maintenance on the vehicle since the time of purchase.
