battery

When I turn on my headlights or when they turn on automatically, the alternator stops charging at 14.4 and drops to 12.5 for days periodically, this only happens when the headlights are turned on other than that the charging system charges at 14.4. The dealership has replaced the alternator...

The original battery in my 2012 R-spec decided to take a crap last weekend. It didn't quit outright but failed to hold a charge over several days. Good thing too, because as it turns out these AGM H8's are not exactly plentiful (around here anyway). I had never looked in the spare...

The AGM battery in Genny is the first one that I've owned. Does anyone know if the battery requires periodic checks of its fluid level like the standard lead-acid batteries?

I just started my 7th year with my 2010 3.8 sedan and still have the original battery (which checks out OK). Any input on how long I can expect the battery to last? Car is garaged in Williamsburg, VA.

Hoiw do I change the battery in my SmartKey. The message has appered few times telling me that the Smartkey battery is weak. I have found many video on how to change the battery on the 2014 and older but nothing on the 2015. ANyone has done it yet?

I guess she is four years old now and it finally got cold here last night, but what a shocker when I tried to unlock the door with no response. I used the manual key to find her dead as a door nail...nothing, nada, not even a light on the dash.. It even took multiple tries to jump start. By...

I tried a search on this forum for "key fob" and "Key fob battery" and got no results; so I am posing the question below. In my manual it says to pry open the key fob to replace the 2032 battery; it shows the key fob separated. However; the manual is silent on how to pry open the key fob...

My fob's battery died the other day so I bought a couple new batteries and proceeded to YouTube to watch a video on the proper method to replace it. Unfortunately, I found one (by a dealer's service manager) which suggested using the key to split the case apart. DO NOT DO THAT! I managed to...

I ordered one of the wallet smart keys when I first got my 5.0. Recently I have been getting a low battery in key warning from the car. I changed the battery in the key fob but still get the message. I left the wallet key at home and the message stopped so now I need a new battery in the wallet...

The power to the USB connector does NOT turn off automatically when you turn off the car. I put my music USB in the USB slot in the car 5 days ago and have not driven the car since. I went to start it this morning and it wouldn't turn over. It's being trickled charged for the rest of the day. I...

I have a 2012 3.8. Apparently I left the trunk ajar and it ran down the battery. I thought these cars had battery run down protection?

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?

A few weeks ago I inadvertently left my rear door ajar overnight and my battery was too low the next morning to start engine. I called Bluelink to come over and jumpstart me and the car has been fine since. I spoke to one of my friends yesterday and he recommended I replace the battery since...

I went to a local dealer yesterday to buy a Certified 2012 Genesis 5.0 with 38,000 miles on it. On the test drive, I noticed the check engine light. They said it was nothing and were going to bring it to the service department to have it checked out. I left. They called me and told me just...

I have a 2013 Genesis sedan with a battery dishcharge problem. Since purchase in Nov '13, I've had to jump it a half a dozen times due to a flat battery. Something is randomly killing it. I can't determine what. After the first two incidents the dealer swapped out the battery and I'm wondering...

I just bought on Tuesday a 2012 Genesis 3.8 with 25k miles. Last night we went to the coffee shop, got coffee, came out to the car and the car went haywire. It wouldn't start but all the lights and started flashing and going crazy. I called Hyundai roadside service for a jump and they came...
