Additionally, an unknown fluid was leaking near the front passenger's side wheel. The vehicle was taken to the dealer, and an oil change was performed but the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was about 63,000.Owner report · Service Brakes, Hydraulic · Apr 2026
My [XXX] son pulled the seatbelt so tight it got wrapped around his neck. When I pulled over to unbuckle it, it was stuck. I turned the car off and on again to try and loosen it, but it didn't work. In the emergency, I had to cut the seatbelt with scissors. It's the passenger seatbelt in the second row, next to the window. I reported the incident to Kia in Puerto Rico by phone. They never called me back. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)Owner report · Seat Belts · Oct 2025

Engine failed...driving down the road with five small children and without warning all the lights came on and started smoking, leaking fuel, power doors failed, steering, acceleration and more. We had to have the car towed to a shop. A when looking into what's happening apparently many others are having to spend thousands to fix this issue and I'm afraid that's where we are. An investigation needs to be opened as this is clearly an ongoing issue for many familiesOwner report · Engine · Aug 2025
While driving on the interstate, about an hour into the trip, there was a banging/tinging sound coming from the front of the van. Immediately the van was pulled off the road to assess the situation as there were NO WARNING MESSAGES OR LIGHTS that came on to alert of any problem. Immediately before hearing the noise, the van had a major loss of power going up a slight incline on the interstate. The van threw a rod and had I not noticed the sound and pulled over, this could have been potentially a deadly situation had I kept driving and the engine completely seized up in the middle of the interstate.Owner report · Engine · Jul 2025

Took in at approximately 72000.00 miles now has a blown head gasket and cracked block. The safety of a breakdown is obvious.Owner report · Engine · Apr 2025
Engine in my 2018 Kia has failed. This should be covered under warranty as van only has 90k miles on it but because I am the second owner they are telling me it is not covered. Several other 2018 Kia's have already been recalled for engine failure. My car was burning oil. This is a manufacturing issue and I am very stressed about paying to get it fixed out of pocket.Owner report · Engine · Oct 2024
I took the vehicle to get serviced to check the engine light coming on. The Kia dealership stated that the CVVT Assembly and Oil Control Valve had to be replaced. The entire engine would have to be replaced if there was engine damage. The check engine would turn off for a couple of days and then turn back on. When the light would turn off, there was a lack of power, causing a lag in the throttle control.Owner report · Engine · Aug 2024
Engine failed. Replacement is required. Currently at dealership where auto was purchased. Dropped off 30 JUL '24. Waitng for replacement.Owner report · Engine · Jul 2024
Since shortly after buying the van we have been getting airbag warning lights. Just about every part of the system has been replaced, but the airbag light still comes back on. Just got the van back from the dealer today for the 9th time, and after about an hour of driving, the light is back on again.Owner report · Air Bags · Jul 2024
