Check Driver Assistance System light came on. It wasn’t until driving at night that I realized the steering wheel had no power. The horn, buttons, and lights all did not work or function. This also caused all driver assistance settings to not work or function. With no power to the steering wheel, their is no way of knowing if the airbag would deploy. The problem was seen by the dealer and after two months of repair attempts, the clock spring was replaced. The light slowly…

The tpms system will stop working and display a message saying check tire pressure monitoring system. While this message is displayed i cannot see any tire pressures and presumably will not receive any warnings about tires losing pressure. It starts working again on its own at seemingly random intervals. The dealership has been asked to look at it and found no issues. They asked to bring it back when the message was displayed but it is difficult to get the message to pop up…

I'm not sure what's going on. It's telling me to start stop the car when it's running and then it will turn off and go into accessory mode even when I'm driving that's dangerous. I took it to Kia a month ago for the same thing but they said they couldn't find anything, but it has to be something if I'm not the only one saying this is happening to their car. my car doesn't even have 8000 miles on my car.

The car completely cut off while driving on the highway going 65 mph. This isn’t the first time it has turned off while driving. I had to pull over and put the car in park before it would turn back on. The error says Accessory Mode. I have taken the vehicle to Kia Dealership in Winston Salem but they told me they are unable to recreate the issue so they are unable to assist with the problem. The car turning off while driving has happened at least 20 times. I have repeatedly…
