Default K900 Battery Drain

My 2017 K900 has had a weird battery drain from day one. If the car sits for more than 4 days without being started it wonít start. The car was bought new and has only 10,000 miles on it. Countless trips to the dealer, phone calls, visits from Kia engineers, etc. Have moved keys away from it when parked in the garage, made sure doors are locked when parked, all to no avail.
Our local dealer has told us ďwe just sell and service them, we donít build them.Ē The lack of care from the dealer in Wichita, KS is extremely disturbing. How is it possible that Kia canít pinpoint this problem? If anyone else has this problem maybe itís time for a class action suit. About ready to dump the car and never buy another Kia...

Sorry to hear about the problem, Dguzman. I'm fortunate to be able to say that I have not had this issue, but if you search around here a little you will see that quite a few other owners have.

I don't believe anybody has been able to post a foolproof solution, though. Please keep us up to date as to what's going on with your car--maybe it can help somebody else.

That's very unfortunate. The dealer is useless. If I were in your shoes, I'd definitely sue them.

I had a similar problem. Did they check the alternator? Start there. But once you change the alternator you will need to change that pesky AGM battery as well.

I do own my 2019 K900 since 01/19 and except of the battery, all is good so far. The battery gave up on me twice, the first time after 19 months of owning the brand-new car, the second battery died only 8 month later. This is no fun because you cannot even access the trunk without the battery working. Both times dealer stated, "bad cell", not sure if I can believe this. I asked them to check what is causing it, but they did nothing except replacing the battery. I specifically asked then to perform an alternator test and they told me they did but could not show me the test results. This is a K900 certified dealer, I guess I need find another one willing to help. I also contacted the KIA K900 Premium Customer Service, but they told me, they cannot help since this is a technical problem. They promised to call the dealer, but I am sure with no results.

You're dealer experience is the exact reason why I will never buy another Kia/Hyundai product. I love my K900 and the G90s; but I refuse to be treated like crap. My certified dealer refuses to find out why my front passenger airbags don't work after a 15 min car ride with a passenger in the seat. I've shown them videos, showed them how to make it occur and they refuse to track it down. Who would want to drive their friends and family in a car that the airbags may or may not work?

I have owned my K900 5.0 since Oct 2014 with no problems. It was delivered to my U.S. dealer in March 2014 - I test drove it then with packing material still in place. In Feb 2020 I was going to take a major trip so I had AutoZone replace this original battery.
My new Genesis GV80 picked up upon arrival to U.S in December has already had a battery replaced.
I had a Cadillac 06 STS - it went through a battery every year I owned it (6).

Did you end up selling your car? Hope everything is sorted out by now.

So, my 2019 just came down with a case of the battery drain after over a year of ownership. The car isn't driven on a daily basis, but gets started and ran at least every two weeks. I made a service appt. to have the oil changed on one of my days off and when I went out to the car to start it, it was deader than ****. I put a smart charger on it and immediately it informed me of a battery failure (was also putting out less than 4 volts). I tried jumping it off another vehicle, but could only get the lights to turn on. I couldn't get enough juice to it to get it to turn over. At that point I decided to call Kia Roadside Assistance since the vehicle is covered under that program.

Roadside Assistance assured me that my local Kia dealership would be able to help me even though they aren't a certified K900 dealer. They performed a load test and determined the battery was indeed faulty and would need replacing. Unfortunately, even though they have the battery in-stock and it's covered under warranty, Kia won't allow them to perform the service, but would do it if I was willing to pay out of pocket to the tune of $350. As a courtesy they checked the parasitic draw and informed me that everything was in spec. So, the dealer said to call roadside assistance again, because Kia won't allow them to call, and inform them that I have a bad battery, which is covered under warranty, and have it towed to a certified dealer.

So, I get on the horn with them again, explain the situation and I get put on hold for a few mins. He calls the next closest dealer about 20 miles away and tells them I need a battery and they said no problem. Two hours later I get a call saying we're ready to install the battery, but it'll cost you $350. I was confused and stated it's covered under warranty, but once again, they're not certified. Again, back on the horn with roadside. I tell her there's at least two dealers in the state that are "certified" to perform mechanical work on my vehicle. She asks which one I'd like it towed to and I said the one closest to my residence, which is about 40 miles away. She informed me the tow is enroute and I'll be getting updates. About a 30 mins. later I receive a text that a tow is enroute. Needless to say, the tow never happened for some reason. I get a call at midnight from roadside stating a tow truck driver is enroute to pickup my car from the dealership. I inform them that the keys are with the vehicle and the dealer has been closed for hours at this point. Right after I hangup with him the tow truck driver calls to inform me he's a few mins. from picking up my vehicle. I inform him of the situation and he says since Kia has already paid him for expenses, he wanted to make sure he wasn't taking money for not doing the job. Thank you for having integrity. So, he said he'd get it first thing in the morning and will text when he's on his way. He just texted stated he's a few mins. from picking it up. What a nightmare, but at least it's not costing me a single dime.
