My heat went out on my 2013 Kia Optima I only had the car for a year what do you think the problem is

SOURCE: 2001 Kia Optima over heating

I figured this out and fixed it on my 2001 Optima. Mine was an electrical problem, not an overheating problem. The problem shows up when there is a heavier than normal load on the electrical system. For most of us, this is when the air conditioner is running full-blast on a hot summer day. However, it was also occuring when I ran the heater full blast. The heater running full-blast should have lowered the temperature, not raise it. So I tested the coolant temp while the gauge was showing it overheating. The coolant temp was not increasing, but the gauge showed that it was. It is caused by a bad ground connection. Another test you can do to see if your problem is the same as mine is this. As soon as the engine is showing overheating, pull over, park the car and turn off the engine. Immediately start the engine again and see what the temp gauge shows. If it still shows hot, you'll know you've really got overheating coolant. If it goes back to normal range, you'll know it's just a bad ground connection. Turning off the engine eliminates the resistance in the electrical system that has beeen building up and causing an erroneous high temp reading.

To fix: Either find and clean ground connections throughout the vehicle until it fixes it, or do what I did. A mechanic at the Kia dealer showed me this. I ran a new wire from an empty bolt-hole on the top of the engine to a bolt into the frame behind the engine. I only added a 6 inch wire and a new bolt into the top of the engine. The bolt into the frame was already there, so I just removed it, put the wire under it, and replaced the bolt. It created a redundant ground that prevented the build-up of resistance that caused the erroneous temp reading. It was a 5 minute fix and it has never done it again. Kia knows about this problem and they put out a post to their shops on how to fix it.

SOURCE: may headlights went out on my 2005 kia optima

It could be a fuse bad connection to the lamps or the switch itself

SOURCE: 2003 kia optima battery light came on and

The alternator has stopped charging for some reason.
First check alternator drive belt is ok;
Check dash 'battery' (or 'ALT') light illuminates when ignition on and motor not running- if not, check 'ALT' lamp is not blown and connections to alternator are ok;
If all above ok, the alternator may be faulty.

If you can't find the stick, then you don't have one, You will have two plugs on the ******. An upper and lower. Check and fill at the upper plug.
