JAKARTA - The National Highway Transportation Safety Administration (NHTSA) in the United States recently started an investigation highlighting Hyundai Ioniq 5, one of the most popular electric crossovers.

Hyundai's Ioniq 5 is facing a potential problem that results in a loss of power on its driving system. Hyundai has realized this concern that affected 39,559 Ioniq 5 units in the United States.

The NHTSA Office of Protects Investigation (ODI) has opened an initial evaluation regarding this issue after receiving 30 complaints from users. They reported hearing loud bursts followed by warning messages on the infotainment system.

Reporting from Carscoops on Monday, June 19, users also reported experiencing sudden power loss after warning messages appeared.

One of the customers filed a complaint with NHTSA regarding this issue affecting Ioniq 5 who is about 12 months old or traveled as far as 16,000 km.

In addition, other customers reported warning voices regarding the failure of the electricity system involving the 12V battery. Fortunately, the battery can be replaced by AAA and the car can be brought to the dealers for further checks.

Customers also expressed their disappointment with the length of time required by the service center to diagnose the problem. After one month, the service still does not provide an accurate estimate of the repair time.

According to ODI, Hyundai suspects the problem is related to the Integrate Control Charging Unit which is responsible for the operation of high-voltage batteries and 12V batteries.

Preliminary investigations showed that excess currents could damage transistors, causing an inability to charge 12V batteries. However, the ODI is still investigating the extent of the severity of this problem that could potentially affect the safety of road users.

Hyundai is working with NHTSA to investigate the case and plans to launch a campaign in July. The manufacturer will update the affected vehicle software and if needed, replace the components.
