Lemberg Law is investigating complaints that the 2022 Honda Ioniq 5 does not have battery heating and preconditioning. Vehicle owners who live in the colder climate areas of the U.S. are complaining that it takes substantially longer to charge their batteries without this function that many were led to believe was a feature of the Ioniq 5. While some cars have the hardware required for preconditioning, the software needed is not available in the U.S.

Is There a Problem with Battery Heating and Preconditioning in the 2022 Hyundai IONIQ 5?

There are multiple problems relating to battery heating and preconditioning in the 2022 Hyundai IONIQ 5. According to the 2022 IONIQ 5 specifications published by Hyundai, the 2022 all-wheel-drive (AWD) IONIQ 5 models are all equipped with a “battery heating system.” But it is commonly known that this is only in the form of hardware.

The free software needed to operate the heating system has been released in parts of the world including Korea, some of Europe, and since mid-November, 2022, in the UK. But it is not currently available in the U.S. or Canada. The specifications also show that rear-wheel-drive (RWD) models don’t have any sort of battery heater. And so, this “update” could not be used even if the software was released in North America.

According to the 2023 IONIQ 5 specifications released by Hyundai USA’s Media Center, all RWD and AWD models have a battery heating system in the form of a “battery preconditioning function.” So, clearly, Hyundai has identified the problem and done something about it.

Also, the functionality of the so-called 2022 update that is available in other parts of the world is understood to be identical to the battery preheating function incorporated in the 2023 model worldwide.

Promotional literature for the international market, published by the South Korean Hyundai Motor Group on August 5, 2022, publicizes the concept “battery preconditioning before fast charging.” This, they say, is why the 2023 IONIQ 5 and Genesis GV60 provide “a battery conditioning mode.” They also talk about their “smart heating strategy” for preheating batteries in the IONIQ 5, GV60, and Kia EV6. No model years (MYs) are mentioned.

What Problems are Hyundai IONIQ 5 Owners Experiencing in Relation to Battery Heating?

U.S. and Canadian owners of the 2022 Hyundai IONIQ 5 are frustrated and angry that they don’t have access to any form of battery heating. Many maintain that they were led to believe by salespeople that battery heating was a feature of the electric vehicle (EV). Others say it was a product feature in the marketing material that was widely available when the car was launched in 2021.

There are also owners who state that the window tag on their cars states that it has a battery pre-heating system and a heat pump.

A reasonably large number of owners state that their 2022 IONIQ 5 has “Winter Mode,” but there is some confusion about what this is. The Owner’s Manual provides some insight.

Essentially it is “recommended to improve driving and DC charging performances during winter by raising the battery temperature to an adequate level.” However, it is only available for vehicles that are equipped with battery heaters.

It is not clear whether those who have the Winter Mode are aware of this and/or how many now have access to battery heating and can use it.

Other Discussion About Battery Heater/Preconditioner Issues

A large number of owners have turned to online forums to express their frustrations and concerns and learn more from other owners. Some forums have multiple threads relating to IONIQ 5 battery heater/preconditioner issues.

From the comments on some of the forums it is clear that there is some consumer confusion about battery heating and preconditioning. In a nutshell, battery preconditioning is a feature used to warm the batteries of modern EVs. This makes it ready to fast-charge. If the battery isn’t warmed, it can take two to three times longer to charge in cold weather.

IONIQ Forum

There are at least five threads on the IONIQ Forum. U.S. members have participated in all conversations:

Inside EVs Forum

This site features a thread started on September 23, 2022 urging Canadian owners to “unit for pre-conditioning!” There are two templates, one for Canadian citizens and one for U.S. IONIQ 5 owners, to use when complaining to Hyundai. The aim is to “highlight to Hyundai how much of an issue this is.”

Speak EV Forum

On September 14, 2022, a U.K. owner of an IONIQ 5 AWD started a thread in the Speak EV Forum, Preconditioning? Highlighting the announcement that the Norwegian 2022 model year (MY22) would be getting preconditioning, he asked, “when will Hyundai UK be telling the owners what is happening?” Subsequently, in November 2022, Hyundai Motor UK Ltd announced that the software update was available via retailers.

Kia EV Forum

On July 7, 2022, a U.S. owner of a 2022 IONIQ 5 started this discussion in the Kia EV Forum. Battery preconditioning announced for 2023 IONIQ 5; does that suggest 2022 15/EV6 may never get the update? The Kia EV6 is manufactured by the Kia Corporation, which is owned by the Hyundai Motor Company. So, unsurprisingly, the discussion in this forum is not only about the Kia, but the IONIQ 5 as well.

What are Forum Members Saying

A lot of forum members are extremely angry. For example, a Canadian whose RWD IONIQ 5 “was borderline undrivable for long distance last winter,” said they had hoped the software upgrade for preheating would solve that.

“But if it’s not coming, then Hyundai sold us a defective car as far as I’m concerned, and they need to either exchange it or fix it. I wonder if there will be a class-action suit since anyone that pre-ordered it before they started selling it wouldn’t have known anything about this issue, and there was no disclaimer about it when we were sold the car, either by the dealer or Hyundai themselves.”

A U.S. owner states he bought his IONIQ 5 AWD with a heat pump specifically for the battery preconditioning feature.

“I will be insanely irritated if it does not come to the 2022 models. I did not know it could not do this at the time of purchase since my salesman was like, ‘oh it has a heat pump and winter mode for the battery.’ He made it sound like it would get conditioned before it’s charged.

“If the 2022 models have all the hardware necessary to do this and they don’t give us an update I would be more than happy to do a class action lawsuit against Kia and Hyundai since you would never see the so called 18 min from 10-80 percent most of the year unless you lived in the perfect environment for charging. Cold gating is completely unacceptable for the price of this car.”

AWD vs RWD

Despite what the specifications published by Hyundai Motor America show, there are some forum members who maintain that RWDs manufactured after June 2022 do have a battery heating system and the hardware for preconditioning.

There are also some who are convinced that because the software is available for AWD vehicles in other countries, it is possible that Hyundai USA is simply refusing to distribute it.

Hyundai Hasn’t Said U.S. Owners Won’t Get the Update

On the contrary, representatives of Hyundai Motor America have been telling U.S. owners of the AWD IONIQ 5 they are working on a solution. What puzzles many owners, though, is that the update solution is already available elsewhere in the world.

As an owner from Canada states, “Hyundai knows exactly what the solution is. The same solution (is) already in use in South Korea and Europe. More delay tactics.”

Canada Hyundai is, though, telling owners the update is not possible on 2022 models, “due to technical limitations.”

The person responsible for the YouTube announcement mentioned above, stating that the software update would not be released in the U.S., retracted his comments, maintaining they were “no longer accurate.” Instead, he said, “the update is going to be happening very soon!” That was three months ago!

Another forum member says:

“I’ve seen a lot of back and forth about whether or not most of our earlier 2022 models would get battery preconditioning. I have something in writing from a senior manager within Hyundai Motor America that says they are working on it! (I’m) not going to believe it 100% as fact but at least I’m more hopeful now that it could happen!”

A Canadian member of the IONIQ Forum who owns an AWD, states, “We’re making progress with Hyundai Canada, so those in the US who care should continue to push Hyundai of America!” Two months ago, he was told by someone from Customer Relations: “We understand your concerns about battery preconditioning, and whether this update will be made available for your vehicle.” He said they were actively working with the Hyundai Motor Group “to provide a resolution for Canadian Customers at the earliest convenience.”

By all other accounts, that definitely isn’t going to happen.

What Should You Do if Your IONIQ 5 Doesn’t Have a Battery Heater/Preconditioner?

If you purchased a new 2022 Hyundai IONIQ 5 and were told that it had an operative battery heater/preconditioner, you are welcome to contact Lemberg Law. We understand that, at least initially, only the AWD cars were equipped with preconditioners. We also know that even those that have the hardware were not supplied with the software needed to utilize the hardware. But circumstances differ and we will need to assess yours to see if you qualify to join our class action investigation.

If you’d like to join the investigation, please call us at 844-928-4443 or complete our case evaluation form. It’s not going to cost you a cent because the law says that Hyundai must pay the legal bills.

    I Have Ioniq5 2022 SEL, RWD
    If Hyundai claimed fast charging batteries it can not limited just to warm weather, we the consumers should be able to do it in cold winter and I bought the car with fast charging ability in my mind At first place.
    I believe Hyundai corporate should correct this and upgrade 2022 models to have preconditioning batteries abilities since they claimed fast 18 minutes charging time for this car. So charging time shouldn’t take twice or up to three times more because it is winter, it is not a fair for what been advertised. When I bought the car I was first person in that dealership bought the car and seals man did not know everything about the car! So when I was asking questions about the car he were just tell me yes convinced me oh it has it all but it was not the case! something like this like charging condition I think Hyundai is responsible and most deliveries what they promised, Any how charging in the cold takes lots of time and all EV cars should have preconditioning battery warmer/ heat pump. No car must put other cars on long waiting time to charge only because is not equipped with battery warmer and heat pump for batteries, these cars are expensive and I am sure engineers had this in their mind but it’s corporate profitability on the way most the time like canceling spare tire in short that cheap tire if I had would be convenient just small size tire to get me to repair shop but it did cost my whole working day at the end I had to buy new tire $300 and $75 inflator kit
    . So stop worrying about so much profit Hyundai let’s think this though all EVCar must have pre warming ability to be faster at charging stations so other cars come after can get to charging their car faster regardless the brand or model.
