Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The air bag indicator light is on, and I'm told by Kia that the weight sensor for one seat is not functioning, which means air bags will not deploy. This is a substantial cost to fix of approximately $1,600.00, however, this light has been on for some time and I feel that it is likely a defect in the sensor, electrical components, or air bag that may be impacting other Kia owners.”

“The door actuator went out. The door worked fine when we went to the store. On the drive home the sliding door flew open. The door latch is stuck in the locked position and will not unlock. I have my doors bungee corded together.”

“Rear driver side sliding door will not always close completely and sometimes opens while driving. My three year old granddaughter sits in that seat and I'm worried that the door is actually going to come open while we're driving the car. I've read of previous years for this same vehicle having this problem. I've paid to have it repaired once, but I feel that Kia should take care of this known issue. Also, there is an issue with the front end of the vehicle. It sometimes makes a grinding sound when I'm slowing down - not necessarily with my foot on the brake. …”

“While driving with my 4 year old twins in my 2012 Kia Sedona the passenger power sliding door repeatedly opened while the vehicle was in motion. The first time I was actually entering the expressway on the on-ramp - not certain of my exact speed but I was accelerating to allow me to yield into traffic. I obviously pulled the van over immediately - my daughters and I both frantic. This was the second issue with the power doors that particular evening. The first issue occurred approx. 10 minutes earlier when I was unable to get either door to open at all. …”
