I was driving the vehicle home on the freeway after just buying it. I had only driven it for about 35-40 minutes and after 5 minutes the ev battery was drained completely and the car was running in hybrid mode. The vehicle suddenly lost all its power and a warning light came on flashing saying "check hybrid system turn off engine". I was forced to put on my emergency lights and quickly move over to the side of the freeway because the car lost so much power so quickly. It felt like the engine died and when i tried hitting the gas the vehicle would jerk. ONCE I got to a safe spot on the freeway. I called AAA to get a tow, then called the dealer to tell them. My wife and I have now checked the recalls for this car and all the customer complaints. There seems to be a similarity with the engine recall and or the hybrid electrical recall. It seems like Kia is making sure to cover its tracks with the cars so it doesn't have all the 2017 models in the recalls affecting the hybrid system as well as the defects with the engine components. There is definitely a problem. But i saw in the carfax that the vehicle was inspected a lot by KIA and that is why i would like it to get inspected by a 3rd party. I would like to get the vehicle inspected by a 3rd party before taking it to a KIA dealer but I don't have a lot of money. Can you help with this at all. Please contact me asap. You have the Vin. I told you I just bought the car so I am going to either see if the dealership I bought it from will fix the problem since it broke down the day I bought it. You should be able to see we bought the car from by looking at the carfax for the Vin. And you have my permission to also be able to get my phone numbers from that dealer I really don't think KIA should get away with these hybrid/engine problems with the car. Its very unfair to the consumers. If they as a manufacturer and dealerships are doing quick fixes when doing regularly scheduled maintenance. Thats unethical.

We have the Arctic Snow white color on our Kia. The paint began peeling shortly after our purchase in 2016. It has continued to peel throughout the entire time we have owned the vehicle.

The auto stop start function of this car is very unsafe. It sometimes does not start back immediately and rolls back. It’s just very unsafe.

The engine of my 2018 Kia Optima is burning oil. When it started, I had 72,000 miles, and it's burning one quart of oil every thousand miles. There is no oil leak. I will take it back to Kia on October 2, 2025. The mechanic reported that it has an internal engine issue.

I am submitting this complaint regarding my Kia Carnival. The vehicle has a recurring and dangerous problem where the engine suddenly jumps and, if I continue pressing the gas, it shuts off while driving. This has happened multiple times, including in the middle of the highway, creating a serious safety risk for myself, my passengers, and other drivers. I have taken the vehicle to a Kia dealership on multiple occasions, but they have not been able to identify or repair the issue. I also contacted Kia corporate, obtained a case number, and was told someone would follow up with me. Unfortunately, no one has ever called me back. This is an ongoing and unresolved defect that puts my family and the public in danger. I request that the NHTSA investigate this matter to determine if this is part of a larger safety defect in Kia Carnival vehicles.

At highway speeds and in windy conditions, both side view mirrors partially fold inwards obstructing the ability to check blinds spots. The vehicle was purchased new from a dealership a month ago. The dealership has been notified of this issue as well as the check engine light being on since the vehicle was 5 days old and we were told they are unable to take the vehicle in until they have a loaner car available. Attached are two images of the driver's sideview mirror showing the approximate distance the mirror folds inwards with little effort.

I was driving in normal operating conditions, with no traffic when suddenly the engine seized. After contacting a towing company to get my vehicle home, I started checking for anything I could find and noticed that it had zero oil and no visual signs of a leak anywhere. There were never any warning lights or sounds until it abruptly stopped. I have not had it looked at by anyone other than myself and a neighbor whom is a mechanic.
