Kia Rio Electrical issues

    I think they'll take you seriously, especially if you mention safety concerns. I also think it's electrical in nature--perhaps a malfunctioning brake light switch. This start/stop feature is integrated into a number of the car's systems (temp sensor, battery condition, engine RPMs, etc) so it could be a bit tricky to track down an intermittent problem. You may have to be patient with the dealer and/or the system might have to fail completely before it can be remedied.

    The car is heading for the dealership for warranty work due to the UVO system and display being intermittent. My daughter will be taking it, as the car is not local. As she has not dealt with dealerships before concerning warranty maintenance, I want to arm her with info about any known problems with this system beforehand so that the service department will not treat her wrong.

    She told me the UVO system ocasionally resets when the car is shut down and restarted. Have not disconnected the battery as of yet, as I have been told by one dealership that there is a dealership reboot required for the cars electronics when the battery has been disconnected. I have not verified if this is correct or not.

    There has been some discussion on another Edmunds forum about the DRLs (Daytime Running Lights) on the 2012 & 2013 Rio5 SX. Do any owners here have an SX with DRLs? If so, do the DRLs use the LEDs below the headlights or reduced power of the high beam lights? Thanks!
  • I have a 2007 Rio with the battery drain problem. It has been going on for years until I noticed it only happens in the summer. If the A/C is left on when the engine is turned off, it appears some kind of relay is left on which drains the battery, rather quickly. Perhaps the AC clutch?

    A jump will always get the car started and everything is fine until the AC is accidentally left on again. Clearly some kind of design problem. I have seen other complaints about this online, but good luck trying to get Kia to acknowledge or fix the underlying cause.

    First time I'm posting here, hopefully someone can help....

    My 15A "Room" fuse under the hood keeps blowing, there is obviously a short somewhere but I can't find it, neither can the Kia mechanic.

    I disconnected my stereo, clock, dome lights, trunk light and AC and the short is still there, even while the car is turned off and the key is removed (all the doors are closed as well)

    Anyone else have this issue? Is there anything else that is connected to this fuse that could be causing the issue?

  • I have a 2007 kia rio and it has started the battery drain problem. I make sure every time I turn it off that everything is off...a/c, radio, lites...etc...yet it will decide not to start without any warning....I end up having to get a boost and never know when it will happen again. I have been told it was not the battery, alternator or starter. I have gone thru three new batteries since I bought this car. this intermittent start problem just started a few months ago. any one had success in getting this fixed?
  • I have a 2008 Kia Rio5 and was having problems with the battery occasionally and seemingly randomly being dead. Apparently, if you unlock your car, open a door to take something out and lock it again without starting it, it will send power to the accessories which will drain the battery. In retrospect, that makes sense of most of the problems. I had. Hope this helps!

    My Daughter just purchased a 2001 Kia Rio.It is running a little rough so we took it in to have the codes read.According to the shop the P code is"cpkl" which apparently is the fuel injectors.When I pulled the middle 2 connections from the injectors it didn't make a difference on the way it run.I have tried injector cleaner but no help.Could it possibly be a bad injectors or a fault signal to the injectors.Could someone please help.

    Try checking your upstream HO2 sensor or (oxygen sensor). I was having this issue with my 04 kia rio and was thinking it was injectors, until I stumbled over a manual I got for it at And it stated that the upstream oxygen sensor tells your ecm info to send signals to your injectors. It's worth a shot because they are really easy to replace and may fix your problem.

    My daughter’s 2001 Kia Rio has intermittent starting problems. It may start 10 times in a row however on the 11th try NOTHING. Will not turn over or anything else. The battery is strong but apparently each time it has not started she had it boosted and it started. Makes no sense to me as battery is good.

    I have it in my driveway, started a few times no problem but now will not start, as I said will not even turn over, sounds like an ignition problem to me but I am a novice. Any advice would be appreciated.

    Try checking ECM(cars computer), or possibly ignition coils?
    Did you try checking your alternator? because they will drain even a new battery if given enough time to. Since the alternator is your charging system for your battery. that could be the case.

    I bought a used 2006 rio about 3 months ago. It has less than 50000 miles.The battery has drained on me 2 times. The first time I was at home so it wasn't a big deal. I have 24hour roadside assistance with my insurance so someone came to jump it and I drove it to the dealer. They said the battery was drained and they recharged it. I didn't know what had caused it to drain. I thought maybe door wasn't closed all the way and the interior lights were on or something so I set all of them to off so they don't come on when you open the door. It's been 2 months and I was leaving walmart and the engine died when I was trying to leave. I turned it off and restarted it. I was halfway backed into the aisle and it died again. I tried to restart and it wouldn't start.

    Same problems, except my battery was totaly ruined. Today I have 5th battery in my car within one (1) year.

    I really liked KIA. But after this experience, I'm not sure about their cars at all.

    Have you had your alternator checked?

    I am having the same problem as #14. Did you ever find out why. I need to get my car inspected and it won't pass with this problem

    upstream heated oxygen sensor

  • Kia Rio 2013 SX hatchback. The abs, brake, traction control, and tire pressure warning lights come on randomly while driving. Sometimes the outside temperature will change from an actual figure to two dashes. The air conditioner will blow hot every time that happens. The air conditioner blows cold again as soon as the outside temperature updates to an actual figure. The warning lights randomly come on and sometimes flash. Even more occasionally the airbags and another warning light that looks like a steering wheel with an exclamation mark will come on when all the others are on. Sometimes I can reset them by turning the car off for a minute and back on. This has been happening for a few months, very randomly and not very often. Last Saturday it all happened about twenty times in a row while driving for about an hour. All the lights come on, stay on for a couple of minutes, then go off for a couple of minutes, rinse and repeat. The drive home had no issues, same hour long drive. This morning all the lights were on and stayed on as soon as I got in the car and started it for the first time today. They did the normal stay on, blink, go out, etc. along with the outside temperature and air conditioner issue. But they never went out for an extended period as they have before. Also, the car seemed to have an issue with shifting and felt sluggish. This is a new symptom only happening this morning. I drove straight to the kia dealer. I spent about half an hour explaining all this to them. The service advisor even saw the lights on. I received a call about three hours later. The dealer is telling me they cannot get any of the conditions to occur now. No lights, nothing, they said the computer isn't reporting any issues and has no fault codes. They are at a loss as to what to do. I am thinking I will have to just drive it until it completely fails. Any ideas?

    Electrical gremlins can be very difficult to pin down, and if they can't get the conditions to happen again, they can't simply start guessing and doing things that will cost you money. As long as the car is functioning and the lights don't seem to affect that, driving until the condition is "permanent" may be an option, but I personally would be very observant of what's going on with the car. Your observation of shifting and sluggishness might be related it might not. It simply could be that you're just on a heightened awareness and noticing things that are normal or have been there all along, but now look or feel strange. Sort of like when you notice a perfectly normal noise in your car, but it gets into your head wondering what could be causing it and wondering if it's a problem.

    I always start to write things down and keep a log of what's happening to try and see if there's a pattern of conditions that might be causing the issue.

    The whole outside temp display going to dashes and making the air conditioner blow hot air has my mind leaning towards an electronic/computer type of gremlin rather than some kind of physical wiring issue.

    Keep us posted on how things are going. Sometimes just writing it down here and rereading it will throw light on things.

    I bought a 2012 Kia Rio 9 months ago. The rear defrost button clicks on and off all the time and it started killing my battery after my car was turned off for even 20 minutes. I've taken it back to the dealership and they don't know whats causing it. Whenever I go over bumps or make left turns it really acts up. You can hear it clicking really loud in the fuse box & the Kia dealership replaced the fuse box but it is still doing it. Anybody know of anything??? Very strange.

    Sure seems like a short somewhere, especially when you talk about going over bumps and making left turns. Something is loose and moving around. All sorts of videos online about finding shorts.
    shows a clever device, but it's a bit pricey at just over $100. Here's another that shows how to do it using just a test light
