KIA Complaints

Engine piston recall defect. Car has been at the dealership 12 days today and has been diagnosed and has been submitted to a Kia corporate case for repair free of charge. Car had no warning lights on and basically blew up on me driving home from my overnight work shift Thursday into Friday, July 31 morning. Every day they tell me they will give me a loaner and every day they lie. I have called until I’m blue in the face and no action has happened. I’m making a report because I’m about to lose my home and the car in the shop being repaired both because I’m stranded at my house as a single woman with a child with no alternate transportation. It is at the Kia dealership in Southhaven Mississippi 745 East Goodman Rd. I maintained this vehicle and paid every single note on time and did nothing wrong. I’m gonna lose everything because of this recall repair needed that I never knew anything about. It wasn’t on my auto report in 2024 when I bought the car somehow or I probably wouldn’t have bought it with any engine issues but I was unaware. The car literally never had any lights on or issues until the morning when it blew up. During this time I thought I was supposed to get alternate transportation and that hasn’t happened. Because I invested in Kia I’m the only one suffering right now about to lose my home and job because they have my car and won’t give me alternate transportation. A free repair is no good if you’re going to lose everything you work hard to maintain while it’s being repaired. I will never buy Kia again and I will never tell anyone else to buy. Absolute horrible experience so far. I’ve already paid out-of-pocket for a tow which can’t be reimbursed until 6 to 8 weeks after the repair is complete from what I read. If I end up homeless over this 6 year old car I thought would last me, I’m not gonna want the car anymore.

I am filing a safety complaint regarding my 2012 Kia Rio, which currently has approximately 150,000 miles. I first became aware of these problems at approximately 120,000 miles. The vehicle has excessive oil consumption despite being consistently and properly maintained. I have been meticulous about maintenance because the vehicle has a lifetime powertrain warranty, and I have documentation and receipts for required maintenance, including regular oil changes and other scheduled services. On multiple occasions, I have taken the vehicle in for a scheduled oil change and discovered that it had little or no oil remaining. Because of this, I have had to begin having oil added between regularly scheduled oil changes. I do not know the exact amount of oil being consumed because I initially had no reason to monitor or measure oil consumption between oil changes. The vehicle also has a recurring catalytic-converter/check-engine warning that comes on, goes off, and later returns. It has experienced noticeable loss of power and has developed a clicking or knocking sound from the engine. When the vehicle is sitting or idling, it can also indicate that it is running hot even though it does not appear to actually be overheating. These problems have continued despite regular, documented maintenance. I am concerned about the safety implications of a vehicle consuming enough oil to have little or no oil remaining before its next scheduled oil change, particularly when there may be no consistent warning to alert the driver that the oil level is dangerously low. I am also concerned about the recurring catalytic-converter warning, loss of engine power, abnormal engine noise, and the possibility of engine or catalytic-converter failure while the vehicle is being driven. I understand that other Kia vehicles have been subject to recalls and investigations involving engine-related defects. I am asking NHTSA to review complaints involving the 2012 Kia Rio and investigate whether exces

Main 12V electrical system failed completely. The engine stalled, the entire dashboard blacked out, and all auxiliary safety power was lost. The vehicle is currently located at Parkway Family Kia and is fully available for inspection. At rush hour freeway speeds, the engine stalled and total electrical failure occurred. Navigating across active lanes without engine power or power steering was extremely difficult. The total blackout killed my hazard lights, preventing me from warning other high-speed drivers. The dead car blocked an active lane on the feeder road, and an inattentive driver nearly struck my stalled, unlit vehicle. With zero hazards, I had to abandon the car and flee to the roadside to avoid a rear-end collision. Additionally, all passenger doors permanently locked, creating a severe entrapment hazard. Not yet. The vehicle was towed to Parkway Family Kia on Tuesday and is currently awaiting an official manufacturer diagnostic inspection by their service technicians. No advance symptoms prior to the day of the incident. At the moment of failure, the dash suddenly lit up with multiple warning lights. Within a tight 1 to 2-minute window, I completely lost power steering, making the vehicle extremely heavy and difficult to maneuver off the highway. Immediately after those 2 minutes, the dashboard and all electrical components went completely dark.

The contact owns a 2013 Kia Optima. The contact stated that while driving approximately 70 MPH with the cruise control activated, there was smoke coming from underneath the passenger’s side of the hood before the vehicle decelerated. The contact stated that moments later there were flames coming from the underneath the hood of the vehicle. The vehicle was parked on the side of the road and flames quickly engulfed the vehicle. The Fire Department was called to the scene and arrived and extinguished the fire. During the fire the vehicle was destroyed and was later towed to a nearby storage facility. While attempting to quickly exit the vehicle the contact fell to the ground and sustained an injured left leg and left side. The cause of the failure was not yet determined. The contact stated that the engine was recently installed related to a recall repair. No additional information was available. The manufacturer and local dealer were notified of the failure. The failure mileage was 140,000.

Vehicle flashes Auto Start Stop icon on the dashboard, which is not commonplace. When this occurs, the vehicle can not accelerate when the accelerator is actuated. The vehicle can not accelerate past 40mph and the RPM is sporadic. This happens randomly and can not be diagnosed by the dealership. Multiple dealerships have tried and none can duplicate this issue. This is a severe safety concern and seems to be common all over multiple forums.

I began to drive. The dashboard display read "Check low voltage supply" or something like that and on the opposite side of the display there was a small image that looks like a 12V battery. A moment later the dashboard display changed to read "DO NOT DRIVE." The car was towed to a dealer who reported a "failed ICCU and High Voltage Fuse." The vehicle was towed to a dealership where it is being repaired under warranty. The same parts were replaced on December 26, 2024, that time because the electric vehicle would no longer accept a charge from a 240VAC source, although it continued accept a charge from a high voltage DC source. At that time there was also a software update that was said to correct the defect.

The contact owns a 2025 Kia Sorento. The contact stated that while driving approximately 75 MPH, the vehicle lost drive power. The vehicle decelerated and was coasted over to the side of the road. The contact stated that several unknown warning lights flashed on the instrument panel while the vehicle was decelerating. While on the side of the road, the check engine warning light remained illuminated. Additionally, the message "Hybrid Power Control Unit" was displayed. The vehicle was towed to the dealer but was not diagnosed because the dealer was unable to reproduce the failure. The vehicle was not repaired. The contact stated that while the dealer was attempting to duplicate the failure, the vehicle was not being driven at highway speeds like when the failure had occurred. The manufacturer was made aware of the issue, and a case was opened. The failure mileage was approximately 30,000.

This is a formal vehicle safety complaint regarding a manufacturer's active refusal to remedy a known safety defect under an active recall campaign guidelines.My 2015 Kia Optima Turbo experienced an active internal mechanical engine knock, violent sputtering, and a complete engine seizure. The vehicle is currently sitting un-driveable at an authorized Kia dealership.The required Knock Sensor Detection System (KSDS) software update was successfully completed on this vehicle prior to the incident, legally qualifying it for a 100% free long-block engine replacement under the manufacturer's active Lifetime Warranty extension. However, the dealership service department is actively withholding the safety warranty paperwork and refusing to submit the diagnostic photos and engine seizure data to corporate for warranty approval unless I agree to pay an additional $800 out of pocket for an external throttle body and O2 sensor.I have explicitly declined the retail accessory charges five separate times. I only authorize the replacement of my front sway bar links. Instead of separating the ticket and processing the free engine block safety remedy, the dealer is holding my safety warranty hostage to force a retail sale. Furthermore, a manufacturer consumer care representative recently refused to listen to my request on this matter and dropped the call.The manufacturer is using internal technical advice to block a court-ordered safety remedy and is allowing a dealership to use unauthorized retail accessory charges to deny me a safe, operating vehicle. I request immediate federal intervention to force the manufacturer to release the free engine block safety replacement order to the dealer and halt these predatory dealer practices.

While driving on the expressway posted speed 65 was doing 70, left lane driving, suddenly my check engine light started flashing, my oil light came on and my vehicle started slowing down. Acceleration was not an option, causing hazardous conditions to have to put my hazards on and cross two lanes of heavy traffic. Vehicle went into limp mode. Vehicle was caught up on an oil change, and was regularly checked and filled with oil. Oil seemed to have been burning rapidly or just simply disappearing. The motor blew and i purchased this vehicle less than 6 months ago. I only put 4,000 miles on it. 2020 kia sportage s, dealership was lilliston ford. Took vehicle to kia dealership to get two safety campaigns fixed. They informed me i was only a couple hundred miles over my warranty and my repairs are not covered. I now have an inoperable vehicle that i have payments on, which now needs a new engine. No recalls matching my vin, only my make, model and year. All repairs were denied. Worst vehicle decision ive ever made…

The systems affected appear to be engine, powertrain, and vehicle speed control. My 2014 Kia Forte, VIN [XXX] has approximately 118,000 miles. Since purchase in November2025 from Wondries Toyota, the vehicle has had repeated high RPM, poor acceleration, and loss of power when entering freeway on-ramps and driving uphill. It struggles to accelerate while merging into faster traffic, creating a safety risk as vehicles behind approach at higher speeds. Two different mechanics verbally advised that there may be an oil leak or oil consumption issue affecting the catalytic converter. I replaced the catalytic converter a couple months ago, but it became clogged again and the power loss continues. The vehicle is available for inspection. The problem has not been inspected by the manufacturer yet, and I don’t have a written diagnostic report at this time. There was no crash, fire, injury, or fatality, and no police report. Warning lights are unknown. The exact incident date is approximate. The issue has been ongoing since after purchase and occurs multiple times, especially during freeway merging and uphill driving.
