It is currently the NHTSA’s (National Highway Traffic Safety Administration’s) Examining the Hyundai Ioniq 5 crossover’s safety. The research was conducted after 30 Ioniq owners had concerns about power outages. The Integrated Control Charging Unit (ICCU) is at fault, according to Hyundai and the Office of Defects Investigation. The NHTSA evaluates the Hyundai Ioniq 5 and the 2022 Kia EV6 for power loss while moving. The owners of both EVs have said that the power goes down or goes away while they are driving. The Kia has been the subject of 11 complaints, according to a report sent to the NHTSA on July 3. According to the study, “many consumers report a loud pop followed by a warning on their dashboard and an immediate loss of motive power,” which can be a partial or complete loss of power. There could be a problem with 19,824 2022 Kia EV6 EVs. Similar to the Ioniq 5, this is being looked into, but cars have yet to be called back. The NHTSA’s Office of Defects Investigation (ODI) examines Hyundai’s well-known and popular Ioniq 5 electric crossover. The study was done because thirty people said their Ioniq 5s lost power while moving. Currently, the probe only applies to Ioniq 5s cars made in 2022. The NHTSA says that many customer reports involve a loud popping sound from inside the car, followed by a warning on the dashboard and a sudden loss of power ranging from a small drop to a total loss. The ODI talked to several owners, who said that the power went out and happened at different times after the warning message. According to NHTSA records, Hyundai said the failure was caused by the Integrated Charging Control Unit (ICCU), which is in charge of powering the primary vehicle and low-voltage 12V accessory batteries. Hyundai’s first study found that the problem could be caused by an ICCU over-current, which can damage the transistors in the 12V battery system and make it hard for the battery to charge. Hyundai said, “We value our cooperation with NHTSA and have been in regular, open, and honest communication with the agency.” In July, the company plans to run a service program that will include software updates and, if necessary, ICCU replacements. Even though the investigation is ongoing, it is unclear if the NHTSA will start a total recall. Even though an ODI probe could lead to a memory, the NHTSA considers investigations and recalls two different things. The NHTSA’s recalls page has more information for car owners worried their car may be part of a recall.
