KIA Complaints

Engine warning lamp illuminated as the engine lost some power. Code was diagnosed as the knock sensor issue. Unit taken to mechanic to evaluate and diagnose. Repair shop notified us that based on the sensor, the engine could succumb to a failure at any time. Engine oil was flushed, cleaned, and replaced. Code was addressed currently. This is similar to the failures observed by other engines in this class, however, it does not appear this engine is part of the lifetime warranty or recall.

On 1/26/2024 approximately 9am, my husband had been driving on the highway for about 2 hours and pulled over to shut his eyes for a few minutes. He shut off the engine, closed his eyes and immediately smelled smoke. Black smoke began coming from under the hood and quickly got worse. He quickly got out of the car and walked away. He heard a loud pop sound and the engine area was engulfed in flames. He called 911. It took about 10 min for the fire dept to arrive and by then, the fire was being fed by the gas in the tank. They tried to put out the fire but the car burnt completely due to the gasoline. No one was hurt, thank goodness. There were no active lawsuits that I could find to get some compensation for this loss. We had to pay our high deductible and lost personal belongings in the car. This car did have an ongoing oil consumption issue. We had to replace the oil more frequently than normally required and it used much more oil than normal. We were told we had to wait for engine failure to get any kind of resolution.

The contact owns a 2014 Kia Soul. The contact received notification of NHTSA Campaign Number: 20V750000 (Engine). The contact stated that while the vehicle was parked, the contact observed a leak underneath the engine compartment. The vehicle was taken to a dealer, where it was determined that the master seal was leaking and needed to be replaced. The vehicle was not repaired. The repairs were denied due to the failure not being covered under the recall. The vehicle was then taken to an independent mechanic, where it was diagnosed and it was determined that the master seal needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, and a complaint was filed. The failure mileage was approximately 90,140.

The first problem part is the airbag. The clockspring was fixed twice under warranty. Then the dealership said they wont keep doing it and blamed me wrongly. I had a private mechanic repair the same part twice due to the code it was giving but it turns out thats not what's wrong with it. The entire airbag and electrical components are bad, that is why the two repairs the dealership as well as the private mechanic made did not work. We also have some engine problems they wont continue to fix because my warranty is now surpassed. The car burns through 20 quarts of oil in between changes, it has no leaks. It has so much carbon buildup. They replaced a gasket and thats another part that has continually needed replaced but they did not fix the issue that has caused it to go bad. When the small mechanics hear about the issue they are confused because the type of motor I have was recalled in other cars for the same issues. My car just recently surpassed the warranty, I should not be having to still fight the dealership to have a car in working condition for the same problems they kept putting bandaid on during warranty repairs.

I own a 2020 Kia Sorento. There is currently a class action lawsuit settlement ongoing. I have been informed that my 2020 Kia Sorento is not eligible while the settlement clearly states the 2020 Kia Sorento is included as part of the settlement. My Kia’s engine did not fail until after the settlement was finalized because I don’t drive a lot anymore and my mileage was just over a 100,000 miles when it started showing problems. It seems to be a new timeline for new claims and I’m still not allowed to file a claim for the same reason. I bought my car new in 2020. If you need additional information, please advise.

My transmission failed at 95k miles and was available for inspection at a fee. My safety was at risk since my car was jerking on the highway and I had to quickly pull over while the car slowed down in a fast and high trafficked area. The problem has been an ongoing issue especially in 2020 models from social media and the dealership. The vehicle was inspected by the Kia dealership. The engine light did not come on until the car showed immediate signs of issues.

I purchased this vehicle new in September 2025. At approximately 3,903 miles, the vehicle exhibited a failure of the transmission system affecting its ability to remain stationary when placed in park. When the vehicle was placed in “Park” on an incline, the park mechanism failed to hold the vehicle, and the vehicle rolled despite being in park. This condition presents a clear risk of unintended vehicle movement. The issue was verified by the dealership during a test drive. Diagnostic inspection confirmed that the gear selector and transmission position indicators were functioning correctly; however, the vehicle continued to roll freely in park. The parking pawl was audibly engaging but failed to mechanically secure the vehicle. No diagnostic trouble codes were present, and no evidence of external damage, improper use, or installation issues was identified. The failure appears to be internal to the transmission system. This defect occurred at very low mileage and involves a core safety function intended to prevent unintended vehicle movement. Based on these facts, this issue is being reported as a potential safety-related defect. The dealer had the vehicle for over 30 days and installed a completely new transmission.

The infotainment system in my 2022 Kia K5 began failing on or around early December, 2025, at approximately 44,000 miles and has continued to worsen. The vehicle is currently at approximately 47,000 miles. The screen displays the Kia startup screen repeatedly and does not fully load, flashing, becoming unresponsive, and ultimately causing distraction while driving. Audio may still function, but key features such as Bluetooth, Apple CarPlay, and auxiliary input do not work. The backup camera will either not function at all or will flash intermittently while reversing. This failure affects safe operation of the vehicle because it limits access to vehicle controls and creates distraction while driving due to the malfunctioning display. It also impacts visibility and usability of integrated systems that are expected to function reliably. The problem has been reproduced consistently and was evaluated by a Kia dealership. The dealership was unable to determine a clear cause for the failure but recommended full replacement of the infotainment system at a cost of approximately $6,700. There were no clear warning messages prior to failure. The issue has persisted despite attempts to reset the system and power cycle the vehicle. This appears to be a premature failure of a critical electronic system that should not occur at this mileage.

The horn stops working when it’s cold and the horn installed does not match the amperage need for the vehicle. It has failed multiple times. I rarely use my horn. It failed for the first time around 20,000 miles. Separately, I have an oil leak that is also covered under warranty. This car has been serviced countless times and it has been in the shop for three weeks.

Engine started knocking loosing power just like our 4cylinder GDI engine. These engines are also not safe to be operating
