Seeking Advice on 2021 Hyundai Ioniq 5 Electric HV-System Issues and Power Loss

Hey there, Funny you should mention it. I had a very similar issue with my 2021 Hyundai Ioniq 5 Electric just last year. But I should point out, I'm not an expert. Just consider myself as a guy with some reasonable car know-how. When the trouble hit, it was a puzzling headache, so I ended up carting my car to a local mechanic. Turned out there was a defect with individual parts in the high-voltage system. They didn't even charge me for the fix because it was covered under warranty. I ended up paying exactly €0.00. One thing I'd recommend is to get some professional eyes on your car's condition. By the way, do you get errors on ignition or while driving? And does your battery drain out totally or only partially? Answering these questions might help us dig a bit deeper. Good luck!

Hey! Wow, that's something to ponder about. If it's a high-voltage system glitch, the fact that it was covered under the warranty for your 2021 Hyundai Ioniq 5 gives me a bit of hope! About the errors, it's really erratic. Sometimes I get error signs right at ignition and other times while driving. Can't really spot a pattern yet. And for the battery, it's not draining out completely, just seems weaker than usual, especially when starting the car. It's got about 25402 km on it since the last service. Probably high time I show it to a mechanic. Thanks for the insight!

No worries Yeah, once the erratics start, best not to take chances. The check engine light or other warnings are there for a reason. Sometimes they could be false alarms. But you'd rather wanna check 'em out and be on the safe side. Your battery-related situation reminds me of what I had. Mine wasn't a total drain out either. Once the engine got running after a couple of tries, the power came back. I do remember the mechanic mentioning that an issue with the HV-system can definitely affect the battery strength on startup. So it seems likely, given your experience. Another thing that seemed to help was keeping the service up to date. Ever since I started ensuring regular servicing, haven’t had another recurrence. Remember, warranty is your friend here. If my situation is any comparable, you might not even have to shell out much! Do keep us updated after you've taken it to a mechanic. Good luck with the fix!

Hey there, Appreciate the advice! It's comforting to know I'm not the only one who's faced something like this. Well, my beast of a car has definitely got some quirks, but I've grown attached to it over the years. It does start up after a few tries so your experience makes sense in my case too. And you're completely right, shouldn't take the warnings lightly. Better safe than sorry. Oh and you bet, I'm definitely checking on the warranty situation. That could save me some greens. Fingers crossed! I'll definitely let you guys know how it went after I've taken it to the mechanic. Thanks again for your help. Cheers!
