Hyundai makes many popular SUVs, but the Ioniq 5 EV has been a big hit among shoppers. Some of the most common 2022 Hyundai Ioniq 5 problems are related to electrical issues. While the 2022 Ioniq 5 hasn’t been on the market very long, Hyundai’s electric sport utility vehicle issues have recently ramped up. Something called the Integrated Charging Control Unit (ICCU) has been a subject of interest and could be the culprit.

Some of the most common 2022 Hyundai Ioniq 5 problems are electrical

The National Highway Traffic Safety Administration has many purposes, but one is collecting driver complaints. On the NHTSA listing for the 2022 Hyundai Ioniq 5, there are already 40 complaints from owners. One of the most common 2022 Hyundai Ioniq 5 problems is related to the electrical system.

Since the Ioniq 5 is fully electric, it presents some issues a gasoline vehicle might not have. Drivers complain that the Ioniq 5 will display a message saying, “Check electric vehicle system.” There are other warnings, like “stop vehicle and check power supply,” and one driver even received a warning that said the vehicle needed to pull over immediately.

Some folks found that the electric SUV would drive a bit further, but others noted the Hyundai EV shut down soon after. The Hyundai dealership advised one owner that it should not drive it and that it needed to be brought into the dealership. Others had to pull over to the side of the road immediately as it shut down.

The electrical system is the biggest 2022 Hyundai Ioniq 5 problem

Many of these 2022 Hyundai Ioniq 5 problems are from the last few weeks. Some have noted this issue with the 12-volt battery inside the 2022 Ioniq 5. Others have been able to jump the dead battery to get the EV moveable, but then the dealership noted a fuse problem. Others seem to agree that the Integrated Charging Control Unit (ICCU) has an issue.

The Autopian did a deep dive into the ICCU issue, which helps charge the electric motor and the 12-volt battery. This can also help charge other components or items utilizing the onboard charger. Hyundai notes this can also charge another EV or something like a laptop charger. Either way, it seems Hyundai is aware of the issue so far. Since this appears to be a common problem, the need for ICCU replacements has increased in the last few months.

At this time, the NHTSA does not have a recall for the electrical issues. There are manufacturer communications about the Battery Conditioning function from February and another about the need for updated Vehicle Control Unit (VCU) software. Since the complaints have increased in the last few weeks, an official announcement from the automaker may be coming.

Some drivers complain about the forward collision avoidance system.

Like most modern vehicles, the Hyundai Ioniq 5 is equipped with many safety systems. Some drivers have noted 2022 Hyundai Ioniq 5 problems with the forward collision avoidance system. Either it is too aggressive, goes off too frequently, or does not work as expected. There does not seem to be a known cause for the system to work incorrectly or not go off.

The NHTSA is a good resource if these 2022 Hyundai Ioniq 5 problems sound familiar. Commenting on your issue, especially if it sounds like the ICCU problem, might help other drivers. The NHTSA can communicate directly with Hyundai and help resolve some problems. It sounds like Hyundai dealerships know of the electrical issues but might be struggling with demand. Your local dealership might have more information as it relates to updates.
