I've had that happen in my 2002 mountaineer. what I've found is that if you spray the door latches with wd40 it will clean off the sensors and the door ajar light should go out. but make sure all the doors are shut.
The alarm may go off while driving your Kia due to an electrical shortage. This may also be due to a blown fuse.
The alarm should turn off once you start the car. If the alarm is going off while you are driving, pull over and remove the fuse.
Does it happen only while the car is "off" or does it also happen while driving? If the alarm happens without any apparent reason, even while driving, you may want to check the anti-theft relay. If alarm happens while the car is off, it could be a problem with any of the various switches and sensors that sense alarm conditions.
It sounds like you need a new serpentine fan belt.
Check your hood alignment sensor for the alarm and the trunk sensor
why does my door ajar alarm keep coming on and off while driving my car.
It could be your remote that is faulty and while in motion it can activate. I had that problem. If not, you have a short somewhere in the wiring.
Maybe a possible factory alarm problem !!
Get out unlock the door with the key. Then get back it and try it

probably the fuel pump?
There is no reset. If the alarm goes off while driving and you are buckled in, you need to check the wires going to the seat belt buckle.
