KIA Complaints

I’m experiencing severe oil consumption and spark plug fouling, which are known problems with the GDI engine. This is affecting driveability and may indicate piston ring or valve seal failure.

The fail that the Kia sportage 2025 had is that every time when accelerating the car would bounce back in a violent way. Safety was at risk on busy roads since car was not able to accelerate and instead bounced back making it more dangerous for the car behind. No problem has been confirmed. The car has not been inspected yet. The car seemed as normal without check engine lights or any manual transmission gear activated. Car was on drive and there was no alert or fail shown on screens

The contact owns a 2016 Kia Soul. The contact stated while driving in a parking lot at approximately 10 MPH, the engine seized. The contact was able to coast to a nearby parking space, where the vehicle lost power and shut off. The contact attempted to restart the vehicle and the check engine warning light illuminated. The vehicle was unable to start the vehicle. The vehicle was towed to the residence. The vehicle was inspected by a certified mechanic who diagnosed the vehicle with engine failure. The mechanic suggested that the engine be replaced. The contact became aware of a Software Update Program with an extension for an engine replacement. The vehicle was towed to the dealer and confirmed the diagnostic result. The dealer informed the contact that the engine would not be covered by Kia because the Software Update Program update was not being completed. The manufacturer was informed of the failure and confirmed the decision made by the dealer. The manufacturer stated that the NHTSA was responsible for issuing and informing vehicle owners of a recall. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 144,000.

The contact owns a 2017 Kia Sorento. The contact stated while driving 55 MPH, the vehicle inadvertently lost motive power. No warning lights were illuminated. The vehicle was towed to the residence. The vehicle was then towed to the dealer where it was diagnosed that there was oil intrusion that caused the engine to fail. The contact was told that the engine needed to be replaced. The vehicle was not repaired due to the cost. The contact was informed that documents of past maintenance records were incomplete, and the warranty had expired. The contact stated that in the past, the vehicle consumed an excessive amount of oil. The manufacturer was notified of the failure. The failure mileage was approximately 90,000.

The contact owns a 2017 Kia Sedona. The contact stated that upon start of the vehicle, the air bag warning light illuminated on the instrument panel. The vehicle was taken to a dealer where a diagnostic test was performed, and the dealer discovered that the front passenger's side air bag module was defective and needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 22V031000 (Air Bags). The dealer acknowledged the recall but informed the contact that the repair would be an out-of-pocket expense. The manufacturer was notified of the failure. The failure mileage was unknown.

While driving, the vehicle began running rough and stalled shortly after. It would not restart. The vehicle was towed to a dealership, where they diagnosed “excessive cylinder wall scoring” and no engine compression. This matches the symptoms described in Recall SC336, which affects piston oil rings and can lead to engine failure, stalling, or fire. The dealer confirmed the engine won’t turn over and compression is lost, but they refused to perform the required piston ring inspection under the recall. They stated I would need to pay for an engine tear-down first. However, according to the recall remedy, the inspection and engine replacement should be performed free of charge if symptoms are present. The issue occurred without warning, leaving me without transportation and unable to safely pick up my child. I have opened a case with the manufacturer and am awaiting their review.

The contact owns a 2017 Kia Soul. The contact received notification of NHTSA Campaign Number: 22V031000 (Air Bags); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated the vehicle was consuming one quart of oil every 2-3 days. The oil warning light was illuminated with an abnormal clacking sound coming from the engine. The dealer was contacted and claimed that the vehicle was repaired. The contact sought confirmation from the manufacturer and was informed that the vehicle was not repaired. The vehicle was taken to a certified mechanic who diagnosed the vehicle with engine failure and stated that the spark plug was fractured and was not properly installed. The contact was informed that the engine was only running on 2 cylinders and was running at 1 PSI. The contact was also informed that there was fuel leaking from the exhaust pipe, causing failures with the fuel injectors. The manufacturer was not made aware of the failure. The failure mileage was approximately 97,000. Parts distribution disconnect.

The steering coupler for this vehicle is a cheap part that wears out easily. After just 110,000 miles my steering wheel now has a significant amount of "play" and makes a loud clicking sound while driving, even without moving the steering wheel, due to the amount of "play" in the steering. This is an expensive repair due to having to disassemble the steering column all because the cheap part wears out prematurely. This is a known problem for KIA Optimas and results in very expensive repairs for a very cheap part.

The oil was changed with no leak, and less than 1000 miles later, it all disappeared. Now, it has gone into limp mode and thrown a knock code due to no oil. Having it sent to a shop four times in a week is not okay. If there's no leak and no gasket problems, where did all the oil go? I have more posts about this daily. I have 96,000 miles on this engine with full synthetic changes every time. It was healthy, and now it's not because it's overeating oil. Make it make sense, please.

The engine; I took my vehicle to be serviced at the dealership on Feb 18,2025 due to it making a weird whining noise when accelerating and/or turning causing the check engine light to appear. I was told then that my vehicle had no oil in it due to a leak in the oil housing filter. I paid $1900 to have it repaired. Then on May 20th I had to take my vehicle back to the dealership to be serviced for the same issue but this time was told that the cylinder 3 fuel injector needed to be replaced. I then paid $1200 for it to be repaired. Here it is July 21st and the same issue has happened with the diagnostic code reading Cylinder 3 fuel injector and the vehicle will cut off at any time while driving. I took my vehicle back to the dealership and was told that my vehicle was 4.5 quarts low on oil and this was due to my vehicle burning oil and I need to replace the engine or trade the vehicle in. My vehicle has only 124,000 miles on it and should not be needing a new engine or repairs. I purchased this vehicle used with 106,000 miles on it and has had it for a year. I have researched the issue and found that 40plus others has had the same issue with the same vehicle. This issue needs to be looked into. I'm unable to upload my invoices as proof of defect. I can email them if you would like me too.
