KIA Complaints

Contact states large metal vehicle door trim came off while driving, unknown if accident was caused or other damage to surrounding vehicles. Further states, noticed when large rubber-like molding under door trim was flapping and thunking against door. Contact says water now intrudes into vehicle cabin and suspects constant water inside door affecting door electrical systems. Dealer notified by contact and no remedy provided for this "known issue". Contact is concerned about other trim pieces coming off and penetrating other vehicles at speed with "sharp and pointed edges", as well as electrical fire from water intrusion corrosion. Contact demands further investigation and action by vehicle safety regulators.

My daughter was driving on the highway. She was driving at 65 mph and then the car started to jolt a couple of times. She kept driving and then it started to feel sluggish and lost some power. Would not accelerate over 45 mph. She was almost rear ended several times and people continually swerving in and out around her as she couldn’t maintain the car at a normal pace. It eventually wouldn’t go over 35 mph. Extremely DANGEROUS speed on a highway commute. She was able to finally get off highway. The car stalled. No warning lights ever lit. She was close to home at this point. Drove it home with barely any power. Got it towed to the dealer and transmission was blown and they will not cover it because it’s past warranty of 5 yrs (2nd owner). The car is a 2019 with 53k miles. It should not need a new transmission. Apparently this car is now having many transmission issues. There was a service campaign issued by Kia back in 2018, 2020, and 2022 for this exact problem. Clearly there is an ongoing issue with their transmission. But since it is not a recall, the consumer has no way of know this until after it’s too late. When a transmission just shuts down without any warning, this is a MAJOR safety issue as you no longer are able to properly drive the vehicle. This should be a RECALL. Not an in-house technical bulletin announcement. There’s an abundance of safety concerns associated with this. Let’s not wait for somone to get killed in a car crash because it’s not being corrected by doing a recall on these transmissions that is a continual ongoing issue.

While driving my 2015 Kia optima I was getting ready to turn in to my residence.My car completely shut off but my lights had got dimmed.So I had it towed to the Kia dealership then proceeded to tell me it has three recalls on it.Then a customer service representative said that I would have to pay $200,and something dollars to have my car diagnostic done.Whoever I replied even with these recalls I have to pay for diagnostic test to be done she replies yes,but I’m thinking they are just trying to make money off customers.

My White Kia Sedona Van's paint is flaking and peeling off all around the vehicle. This is not due to poor car of the vehicle or accident due to making contact with any other vehicles or objects. It is literally just falling off of the vehicle. It started about a year ago and is getting significantly worse.

1) My vehicle incurred catastrophic engine failure. The engine stopped running suddenly. It does not crank over. It is available for inspection. It does not run. 2) I am thankful that no one was injured and that the vehicle did not catch fire. 3) There is a safety-related defect in certain 2017 Kia Sorento vehicles. 4) My vehicle was towed to the house and has not been inspected. 5) There were no signs of leaking oil or oil burning. No dashboard lights came on to signal overheating or low oil level. No check engine light ever appeared.

Vehicle Information: Make: Kia Model: Sorento Year: 2020 VIN: [XXX] Mileage: ~80,000 miles Complaint Summary: I am filing a complaint regarding excessive engine oil consumption in my 2020 Kia Sorento. The vehicle burns oil between regular oil changes, requiring frequent top-ups. There are no visible leaks, and this consumption poses a serious safety risk, including potential engine failure or fire hazard. Detailed Description: I purchased the vehicle used from a Kia dealership. I requested an oil consumption test from the dealership, but they refused, stating the vehicle is out of warranty. I contacted Kia Consumer Affairs, and they also refused to authorize the test or provide assistance. This engine issue is widely reported by other owners of the 2020 Sorento and similar Kia vehicles, particularly those with Theta II / GDI engines, which are known for oil consumption problems. The vehicle has approximately 80,000 miles, and the oil consumption is significant enough that I must frequently add oil between changes, creating a safety concern. Actions Taken: Requested an oil consumption test from local Kia dealership — refused. Contacted Kia Consumer Affairs for assistance — refused. Maintained detailed records of oil use and maintenance. Request: I request that the NHTSA investigate this oil consumption issue for my vehicle and the 2020 Kia Sorento model line. I also seek guidance on any recalls, service campaigns, or safety actions related to this defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When I stopped the car in a parking lot, before I could engage the parking brake, the vehicle suddenly accelerated and climbed over the curb adjacent to the side walk. Stopped for few seconds and again suddently started accelerating. I could not stop the car as the brake appeared to be disenaged completely and was going all the way to the floor. The car went on the side walk, and descended on the road from the side walk and crossed the road, climbed on the curb again and stopped on the grassy area. Side airbag on the driver side inflated and the drive seatbelt tightened.

All window regulators failed before 100K miles. This does not allow for windows to open in case of emergency, This problem has been personally confirmed by dealer and also in service bulletin SA418. This is a common problem in this car make/model/year. This component has been known to the manufacturer for defect. No warning lights, just instant lack of window use.

Engine sludge and failure. Engine part failure p0010 began happening within 1 year of Kia engine replacement. It is available for inspection. This creates a problem with acceleration in the vehicle, putting my family's and my safety at risk. This problem has been confirmed by the dealer. The check engine light is one. This part failure and engine sludge (despite consistent maintenance) has caused engine failure again, just 3 years after replacement.

My engine was replaced under the Kia PI1802Y/Z Engine Replacement Program in July of 2024 in August of 2025 after the replacement I began to smell gas in my vehicle and took my vehicle to the Kia dealership to find out what the issue was. They informed me that it was a fuel pump leak due to bad gaskets. I believe the engine replacement was done improperly and should be under the SC172 High Pressure Fuel Outlet Recall Campaign. I have reached out to Kia and the dealership. The dealership is being less than cooperative and Kia is not addressing the issue specifically. The gas leak was significant and was potentially dangerous. It would fill up my entire garage with fumes.
