KIA Complaints

Kia replaced oil filter adapter and now it burns through excessive amounts of oil. 3qts over 1000 miles. KIA wanted to do an oil consumption test but by the end it would have been out of warranty. Engine replacement would then not be covered.

The contact owns a 2013 Kia Sorento. The contact stated that while stopped at a stop light, while depressing the accelerator pedal, the vehicle lost motive power in the intersection. No warning light was illuminated. An independent mechanic was contacted. The vehicle was towed by the warranty company to AAMCO, where it was diagnosed, and determined that the engine needed to be replaced. The contact was informed of an engine recall, and the vehicle was then towed to a local Kia dealer. The vehicle was not repaired. The manufacturer was notified of the failure, and informed the contact that the original owner would have received the recall and that the repair would not be covered. The contact was informed that the former owner should have notified her of the recall. The approximate failure mileage was 114,000.

The contact owns a 2012 Kia Soul. The contact stated that while reversing and parking the vehicle, the steering wheel malfunctioned and became difficult to turn, and the driver was unable to control the direction of the vehicle, causing the rear passenger side wheel to strike the curb. The vehicle was taken to the local dealer, who diagnosed that the steering failure was due to a faulty ignition key. The keys were replaced, but later the vehicle failed to start. The vehicle was towed to the dealer, who indicated that the keys needed to be reprogrammed. The keys were reprogrammed. Later, while at the dealer the steering wheel failure reoccurred. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The failure mileage was 45,000. The VIN was not available.

The engine makes a noise like a knock, when the car is running or the speed increases the noise becomes louder and it feels like a strong blow coming from the engine.

While driving, the check engine light came on. Soon after, the rear floor of my 2021 Kia K5 lifted upward, and I noticed the fuel tank underneath had swollen. When I opened the gas cap, it blew off with force and gasoline sprayed on me, soaking my clothes. This could have caused a fire or explosion. The car is now unsafe to drive, and the rear seat cannot be used because the floor is deformed. I discovered that Kia has a Voluntary Emissions Service Campaign SC288 addressing this exact issue (fuel tank swelling and excessive pressure due to a faulty PCSV valve and EVAP system), but this is clearly a safety hazard, not just an emissions problem. Many other owners have reported the same issue online. I believe this defect should be escalated to a safety recall before someone gets seriously injured or worse.

Engine is consuming a large amount of oil. Oil is gunking up spark plugs causing them to be replaced every 10-12 months. Have to add oil 3-5 times per month. This is our 2nd Kia optima and the first (2011) with seized engine in which Kia paid for replacement.

Dear NHTSA, I am submitting a formal complaint regarding my 2012 Kia Optima, which experienced an engine fire directly related to the defects identified in Kia Safety Recalls SC147, SC200, and SC201. On XXX, my vehicle’s engine failed and caught fire. This is the exact condition covered by the above recalls, which state that affected engines may seize, stall, or ignite. I have been in contact with both a Kia dealership and Kia Consumer Affairs for close to a month without any resolution. The dealership has confirmed that my car requires a complete engine replacement, but Kia has refused to address the recall issue, claiming that other unrelated recalls were not performed. When I previously contacted dealerships to schedule recall repairs, I was told that parts were not available, which prevented me from completing them. In addition to the engine failure, the fire also caused my starter to fail. I was forced to purchase a replacement starter out of pocket, which has added to my financial hardship. I believe I am owed compensation for this expense, as it was a direct result of the safety defect. This situation has caused me severe financial strain, as I relied on my vehicle for work and currently have no income due to its inoperability. Kia has not provided a timeline for repairs, towing coverage, or written confirmation that they remain obligated to remedy this federally mandated safety defect. I am requesting that NHTSA investigate Kia’s refusal to fulfill its recall obligations and intervene to ensure that my vehicle is repaired or replaced in compliance with federal recall requirements. My vehicle details are as follows: •Year/Make/Model: 2012 Kia Optima •VIN: XXXX •Recalls involved: SC147, SC200, SC201 •Incident: Engine fire, vehicle no longer drivable; starter also failed due to fire Please advise on next steps. Thank you for your time and attention to this matter. Sincerely, XXXX XXXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2015 Kia Soul. The contact stated that while starting the vehicle, there was a rattling sound coming from the engine compartment. The rattling sound also occurred while driving at various speeds. The check engine warning light was illuminated. The contact received notification of NHTSA Campaign Number: 20V750000 (Engine). The vehicle was taken to the dealer, who inspected the vehicle and informed the contact that the engine would not be replaced due to the mileage exceeding the mileage limitation of 60,000 and other unstated reasons. The manufacturer was made aware of the issue. The failure mileage was approximately 145,000.

On 10/3 driving at roughly 60mph on the freeway, when going to accelerate, the vehicle would not accelerate with no power going to the engine. The gas motor was not engaging, and the car rapidly decelerated to around 20mph in an incredibly unsafe situation. Coasting it off the freeway, it was towed to the local Kia dealership. No warning lights or any indicators went off during that event. 10/9/2025, I picked up the vehicle after they replaced the high-pressure fuel pump and high-pressure fuel line, I noticed the battery was very low and thought it would charge while driving. As I left the dealership, the vehicle did not engage the gas engine and quickly avoided acceleration - no power was going to the engine. The battery reached a catastrophic low, and the engine failed in a busy intersection - creating another extremely unsafe situation - as I was turning around to return to the dealership. This time the hybrid system warning system went off and the battery and oil lights went on. While waiting for the tow truck, the vehicle would not turn off. It is currently with the dealership, 41k miles on vehicle, 1 year old.
