  1. Kona 2nd Generation (2023-Present)
    I purchased my Kona this past December and after only a couple of weeks my vehicle was in the shop for 9 days attempting to investigate the cause of what was draining my battery after my car wouldn’t start. The service department at the dealership ultimately concluded (falsely I might add) that...
  2. MD (2011-2016) Elantra sedan/coupe
    So long story short, I have an Elantra 2013 with about 150k miles on it. In the winter here it gets around 20 degrees constantly so initially I assumed my battery was dying. After not driving my vehicle for a few days, my car would just.. not have any electricity in it. I mean, the doors...
  3. MC (2006-2011) Accent
    I heard recently battery cables of accents made in the 2000's are outdated and thin and they need to be upgraded to thicker gauge cables. What brand and gauge should I get?
  4. AD (2017-2020) Elantra
    Main Question Does the 2018 Hyundai Elantra have a "smart charging" system that would make the alternator level appear high (15.1) and the battery level might appear low like 9 instead of 10.8 or 10.9? Two shops telling me two different things. Details 2 months ago car wouldn't start. Auto...
  5. PHEV (2022+) Santa Fe
    First 2 weeks with car (purchased new), the fuel line disconnects from engine. Entire car reeks of fuel. They do NOTHING, just say oops. Fast forward 4 months, Christmas Day… go outside and my keys won’t work… app won’t work… car is dead. Battery is dead, can’t even jump it. Never notified from...
  6. 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...
  7. CN7 (2021+) Elantra
    I just bought my 21 Elantra SEL earlier this year. It has 58,000 miles on it and I've had no problems (other than my phone disconnecting randomly) until a few months ago. My car will randomly struggle to start after pushing the button. I hold it down, and it kind of sputters but doesn't turn...
  8. Ioniq 5 Electric Forum
    Hello. I've been to get my car to start preconditioning the battery for charging and it doesn't seem to want to. The temperature is around freezing and the car isn't warmed up. I set a destination for a fast charger that is 5 MI away. No preconditioning begins. I try it with different distances...
  9. Kona 1st Generation (2018–2023)

  10. Veloster
    2012 veloster 1.6 fw style package. I was wondering if anyone could tell me what the red wire that's splice into goes to. If it could run into the alternator Fuze and blow it. Please I cannot understand the wiring diagrams I've seen. They show fuzes om talking about a red wire on left clip by...
  11. MD (2011-2016) Elantra sedan/coupe
    Hello, I would like some advice please on where to connect the negative terminal of the jumper cable from the donor car (or from the JNC660 that I have) A lot of people say to just connect it to the negative of the dead battery A lot of other sources - I believe including the manual - say to...

  13. CN7 (2021+) Elantra
    I have a 2021 Elantra. The battery has died about 6 or 7 times over that last two years. Battery checks out ok. Alternator is ok. I have had it into a dealership and they can't isolate the problem. They said it checks out normal. Yet something must be wrong. So I have a question about...

  15. NX4 (2022+) Tucson
    You're probably thinking, why am I already searching for a battery for a '22 Tucson? Here in the Phoenix area, batteries don't last long due to the extreme, summer heat. I've searched every imaginable battery application chart and no one, other than the Hyundai dealers, offer one. I found one on...

    My 2019 Santa Fe Ultimate 2.0 battery needs to be replaced. What have you guys been using? Any advice on the best price/performance ratio?
  18. TM (2019+) Santa Fe
    Hello All, I posted a recent battery test reading that I had taken in the forum topic related to ISG . It was somewhat linked to one of the reasons ISG is so inconsistent on these vehicles and hardly works. I decided to create this thread to more so document the charging behavior of our...
  19. YF (2011-2014) Sonata/i45
    Hello everyone, I am suspecting that I have a grounding problem. I need some guidance. Thank you in advance First of all my ABS, Brake, and Traction system lights are on. I tried 3 different OBD2 port code readers. There is no code. Since there is no code, the mechanic says there is no...
  20. MD (2011-2016) Elantra sedan/coupe
    Hello All- Looking for a little help in troubleshooting a parasitic battery draw on my 2012 Elantra Limited. There is a constant 250-300 milliamp draw on the battery. If it sits for more than 36 hours the battery will die. Brand new battery and alternator tested good. I just isolated the draw...
