Battery discharge warning...

[synnyster]

Driving home today I kept getting the battery discharge warning please use the system with engine running.this would randomly pop up on the center console lcd screen while I was driving. Anyone else had this happen?

Not while I was driving.

Same here. Always comes up after turning the car off and having media playing, etc. , but not during driving.

Get your alternator checked. It could be a connection issue somewhere between the alternator and battery, but most likely that alternator is giving the first warning sign that it is on the way out.

Happened to me a few months ago. Kept coming on like every 5 minutes all the way until I got home. Started the car up next morning and never got it again since then (knock wood).

This car seems to have a few electrical issues. My rear driver side window would randomly not go down. Only after playing with the button for about 2-3 minutes, it would start to work. The other day, the driver side window would only go down or up one inch at a time! Got home, didn't use the car again until next day and it worked as normal.

If this continues, I recommend you try and video it (safely) then head to your dealer.

Hopefully it is just your standard everyday computer glitch. Unfortunately these things are becoming more common place with computers running almost everything in our cars now. Just last week my passenger side lane change alert was constantly on even though no car was there or even close by. Rather annoying as each time I changed lanes and used the flasher it would beep at me. Stayed like that until the car was shut down and restarted.

Ah, the classic computer reboot! It's amazing how many problems it fixes!

Well good news. No issues since this happened on Thursday.

My brand new Genesis wouldn't start a week after I bought it. Dead battery. Just saying.

Doesn't a "normal" good battery cost about $150? Almost $300 seems ridiculous...

Have you looked at the size of this battery ? It's twice the size of a regular car
and it's a AGM battery --- read this article about it

I surprised the it went dead...somethings not right

There is an earlier discussion about the 2015 Genesis battery at:

http://genesisowners.com/hyundai-genesis-forum/showthread.php?t=16044&highlight=Battery

It appears that a battery replacement could cost up to $400.

This is the same battery that I had in my 2008 BMW M5. It was a piece of crap then and still is. BMW wanted $500 for a replacement. Lots of M5 owners had "Excessive Battery Discharge" warnings with this battery. BMW never acknowledged the problem.
I went to a local battery supply store and bought a better, smaller battery for $110, and it solved all the problems. It even had a higher "cranking" power than the original.
I don't know about the Genesis, but we had to put a trickle charger on the M5 while we swapped batteries. Otherwise the onboard systems would lose ALL settings and you'd have to go back to the dealer for reprogramming.
BMW tried to stop people from installing any other battery by claiming that the car required a "battery reset" on their system. If not, the battery would not charge properly, and wouldn't last 5-7 years. That may be, but I could buy 4 batteries for the price that they were charging, so who cares. That aftermarket battery has been on the car for 4 years and is still going strong!

What frosts me are the posts that I see stating that such-and-such, whatever that might be, is great because BMW or Mercedes does something like this. Yeah. right.

The Hyundai battery has 950CCA and 105 AH ... size is approx. 15x7x7. I don't think you will find a smaller battery with that power punch

Those are impressive stats, as you expect from an impressive sized battery.

But why are they failing?

One theory I've heard is that maybe the batteries are being damaged when going flat after cars are sitting unsold for extended periods.

I'm not sure that it's becoming a major problem yet..I haven't heard of that many failing. However you make a good point about storage... These batteries require a special AGM battery charger and using a standard charger could damage this battery longevity. Who knows how they are charging these batteries at the dealership.

There are going to be a LOT of failed batteries if somebody doesn't tell people they can't charge their battery without a special AGM charger. I'm sure it's mentioned in the manual but it would be very smart to put a sticker on the housing over the charge area letting people know they could damage the battery without the proper charger and void any warranty on it (and to refer to the manual). Hyundai DID replace my battery for free.
