  1. Kona forum
    Been doing some camping with my 2020 Kona SEL. Wondering if there is way to keep the hatch open without draining the battery? Theres a cabin light inside that doesnt have an off switch. Will it turn off automatically after some time even if my hatch is up? Thank you in advanced! (:

  4. Sonata All Hybrid Models (YF/LF)
    Hi all, My 2017 Sonata used to charge the batteries 27 miles the first year I purchased it. Since then , the charging capacity degraded all the way to20 miles total. I consulted the dealer which contacted tech support and he was told this is " by design"... The main reason I purchased the car...
  5. Genesis Coupe BK2 2013-2017
    My battery died during a minor cold spell (just below 32F for two nights, above freezing during the day) and I was able to jump start it. Now the low battery light glows all the time and I get the "Battery Discharge Warning - Please use the system with the engine running to avoid battery...
  6. DN8 (2020+) Sonata
    For the past few months my 2021 N Line has been occasionally giving me a battery discharge warning right after I start it. This is different than the warning you get if you just leave the radio on without the engine running. The warning says Battery Discharging Due to External Electrical...

    My car seems to run rough on idle, (in drive but not going anywhere). It seems like the car is vibrating more than it should. Sometimes it will even jolt or studder like it's trying to go forward, I believe the RPM ticks up ever so slightly when this happens. I've also noticed that when it...
  9. RB (2012-2017) Accent
    Hi, 2015 Hyundai Accent with 125,000 miles. Located in New Hampshire. I noticed as the weather got colder that my headlights were dimming on occasion. I didn't notice it all summer and it appears to get slightly better after I drive the car 20+ miles. I checked battery voltage and it was...

    I have a '12 Accent, with a fairly new battery (ETA: 2 years old). Battery died a couple times recently; engine wouldn't turn over, so started it with portable jump starter I have in the trunk. Thought maybe I left dome light on or something. Then charged the battery today with a trickle...

    We bought our 2008 Hyundai Elantra brand new in 2008. When we bought it, it has this button and we had no idea what it was. We asked about it and what we were told was it was intended to stop your battery from dying. The relay button would activate when the charge on the battery got too low...

    Hey all, new forum member here. I am looking to see if anyone has had a similar issue with their battery. One cold morning my wife got up to go to work and the car wouldn't start and the battery was completely dead, I jumped the car and she went on with her day. A couple days later, battery...

    How can I tell if the battery in my 2016 i10 Premium, is the original it had from the factory in Turkey? Many thanks.
  14. MC (2006-2011) Accent
    I have a 2011 Hyundai Accent that has been having some problems with stalling or just not starting at all. We changed the battery and that got the car started and running well for a while (after it sat for 8 months). Then the car just wouldn't start one day. Checked the fuel pump and wasn't...
  15. AD (2017-2020) Elantra
    Someone told me that I needed to add water to my battery occasionally...? If so, how often, how much, and how would I even check? I've never heard of adding water to the battery, but it sounds like "blinker fluid." Or, something I should not attempt myself for any reason. Still want to be...
  16. Sonata All Hybrid Models (YF/LF)
    I have some hopefully easy questions: When we bought this car it was my understanding it had a lifetime warranty on the hybrid battery. Does this warranty transfer if I sell it? Also, as I recall, the there were only two basic trim levels available on the Hybrid. I distinctly remember we got...

    Hi all, I've been limping my 16 SFS along for about a year now. I've set my meter up to measure current and started pulling fuses. After the car is locked, keys are taken away, and everything goes to sleep, the draw goes from about 3A down to about 60mA. After pulling fuses, here's what I got...
