We own a 2024 Hyundai Ioniq 5. Like most of the online users in the Facebook groups, we are experiencing significant unresolved issues with the ICCU and high voltage battery. Currently the car has been out of service for 90+ days with no ETA for return. Hyundai won't agree to pay for a rental car. The dealer won't give us a comparable loaner car. The car is cool, but the way it fails is terrifying. Basically there's a loud pop inside the car and suddenly you lose power at highway speeds and pray you can get off the road before you get hit by a truck. There is no pattern to it. It happened to us four different times. Hyundai has issued recalls for the ICCU part on the vehicle, but the recall is just replacing the ICCU part with the same part all over again. Some people have had their ICCU fail three times. If you don't believe me check the NHTSA complaints for the vehicle. Every day there are another 5 complaints. The Ioniq 5 gets complaints at a rate 15x higher than the Ford F150. When all of this happens to you (and it will happen if you buy this car) you will be stuck trying to deal with Hyundai's customer service. It's terrible. They take months to get back to you and refuse to help in meaningful ways. Any payments come with you signing something saying that you won't ever sue them and that the matter is fully resolved. Happy to answer any questions, but I would absolutely steer clear of this deal. EDIT: I didn't mention the high voltage battery issues. Apparently a bunch of those were defective too. The Ioniq Guy (on youtube) whose whole channel is talking about this car had two high voltage batteries fail (both his normal car and his loaner car from their media fleet) between December and January. Then, when the battery that was expedited due to him being an influencer was installed it was installed incorrectly and he had to go back two or three times to get it fixed right. The issue with the battery seems to be that in early 2025 they shipped defective car batteries from Hungary. Rather than proactively replacing them they are just waiting for them to fail. When they fail you have to wait 4-6 months for a replacement battery EDIT 2: If for some reason you choose to ignore what I am writing here and buy this vehicle please take a few minutes to review the lemon law in your state. lemon law claims on these vehicles are the one thing that Hyundai is forced to respond to. lots of people have lemoned these cars. keep in mind that your cash will be held up for months as they go through their process. |

Exercise caution with these cars. The ICCU issues are still real. Consider these cars disposable and only buy if you are OK without having your car for extended periods and driving a random loaner like a Tucson while getting warranty work done.

It is otherwise a superior car to Tesla. Really sucks that they refuse to just completely redesign the ICCU. This is like the old Tesla days when they had serious workmanship issues like panels detaching.

Nope. My money is not going to Elon.

All car engines are controlled electronically, and the feds mandated backup cameras and electronic braking.
Your best bet is an older, used car.
So what's funny is - when it was r like $6,000 - people were asking for a lower cost option - to only use it when they had road trips planned. I thought that was dumb, and short sighted, because asking for that will only lead to some sort of monthly charge.
For what it's worth, I bought FSD when it was $3,500 - and even the people at the service center said I should reconsider the purchase, because it may never pan out.
I use it every single time I drive, literally at times from inside my garage.

I have a 2023 HW4 MY. It will be my one and only Tesla. I do not have FSD because 8000 or 100/month is an extraordinarily high price for something where you're still liable for what it does.
FWIW I wouldn't buy a Hyundai EV until the ICCU issues were resolved
