  3. TL (2016-2021) Tucson/IX35
    I wasn't aware that my 2019 Tucson Value had an auxiliary battery, but when trying to remote start it this morning, BlueLink said the auxiliary battery was too low and had to be over 40%. It isn't a Hybrid. Do I really have a second battery or is the message the same regardless? I've owned it...

  5. TG (2006-2011) Azera
    Long story short I have a parasitic battery draw on my 2006 Azera. I have narrowed it down to the Audio 1 and Audio 2 fuses (hopefully will narrow it down to one or the other). I am now stuck as to what to replace and/or test? Any help pointing me in the right direction is greatly appreciated.

    Hyundai won’t help with a warranty issue regarding the battery. Does Hyundai truly suck this bad at helping customers?

  9. HD (2006-2010) Elantra
    Until recently I used to be able to leave the headlights turned in the on position and the lights would turn off when the car is turned off. It seems now that leaving the headlights in the “on” position is causing the battery to drain. I took it took it to AutoZone where they tested the...

  16. YF (2011-2014) Sonata/i45
    After not driving the car for 5 days or so it was dead completely. So I jumped it, as soon as power was restored the horn alarm went off. I don't know if that means anything. Anyway, it had to sit with the jumper for a few minutes to get enough juice to crank and it fired right up. But...
