2023 Hyundai IONIQ 6 Problems and Top Complaints – Is Your Car A Lemon?

Electrical system issues are the main cause of complaints received by the NHTSA from vehicle owners

Updated on Author: Brian Jones | Reviewer: Sergei Lemberg

The 2023 Hyundai IONIQ 6 is an electric mid-size sedan in its first model year. It’s the second EV to be marketed by Hyundai under the IONIQ family. Originally, Hyundai used the name IONIQ for the compact five-door liftback that was produced from 2017 until its discontinuation in 2022. Since then, the nameplate has spun off to also include the IONIQ 5 crossover and the upcoming IONIQ 7.

Deliveries of the IONIQ 6 started in March 2023. As of July 2023, the automaker has only sold 3,245 of these Hyundai EVs to date.

Most Common Problems

While the 2023 Hyundai IONIQ 6 is an electric car, the biggest issues found with the vehicle have to do with the electrical system. As a brand-new model, this EV is going to disappoint a lot of new customers who flock to buy it because of its exceptional range and fast-charging ability.

Problems with Electrical System

  • Decreased charging amperage: The 2023 Hyundai IONIQ 6 is supposed to charge at 40 amps. Customers have had the Chargepoint Home Flex charger installed in their homes to accommodate this charging capability. Even with the charger hardwired into the service panel with a 6-gauge wire and a 60-amp breaker, the IONIQ 6 still has trouble charging at normal rates. For some drivers, charging normally occurs for a short time before it drops off to around 23 amps instead. This is a big difference from the 40 it’s supposed to charge at, cutting the amperage by nearly half.
  • Overheating AC charging inlet temperature: With an OBD2 scanner, owners have been able to monitor the AC charging inlet temperature to see why the EV isn’t charging at normal speeds. It turns out the drop in charging rate occurs because the temperature reaches 240°F. With the electrical system reaching temperatures this high, the equipment can overheat and it also poses a potential fire hazard to owners. This is even more alarming if the overheating occurs while the vehicle is plugged into the garage of someone’s house.
  • Double charging times: With the inability to charge the Hyundai IONIQ 6 at normal amperage rates, the charging time is double what it should be. For people planning trips or waiting to get to work, this additional charging time can pose a serious concern.
  • Electronic malfunction in the heat: Compatible phones and the digital key cannot be used on the charging pad when the interior gets too hot. This is a common occurrence for anyone that drives this car in the South during a heat wave or even parks the vehicle in the sun. To get the system working, the interior must first be cooled down, which takes extra time that many people don’t have, especially if they are running late.

2023 Hyundai Ioniq 6 Recalls

As of now, Hyundai hasn’t issued any recalls for the 2023 IONIQ 6, although there should be several. The vehicle hasn’t been sold to a large population yet, but there are still plenty of legitimate complaints providing that this EV is going to be a problem.

For customers to spend more than $40,000 on a new EV expecting a certain charging time and not getting it – that’s a problem that will need to be addressed. Even more important are the issues that could lead to a car fire. For these reasons, we expect that there will be recalls for the IONIQ 6 in the upcoming months. As more vehicles sell, there should also be additional complaints surfacing that may also turn into more recalls. That tends to be what happens with the first model of a new lineup as all of the bugs get worked out.

    I bought my Hyundai Ioniq 6 on July 19, 2023. On August 31 it gave me a dtc code. I called the 800 number to set up appt at dealership for September 8, 2023. The dealership has my car and will not give me a firm date on when it will be fixed. The dealership is Lee Hyundai of Fayetteville, NC. A recall showed up about the same time. The car would run, but the fuel efficiency was down about 25%-40%.
