“While charging at a level 2 charger (6 kW) the car stop charging at 61% for no apparent reason. I was unable to restart charging. Within 2-3 minutes of starting the car and driving, received a warning to “check the vehicle electrical system” and then within another minute or two, another warning to “stop vehicle and check power supply.” I was traveling under 20 mph the entire time.”

NHTSA complaint #11708691, filed 2026-01

“I was traveling on the freeway when I got a warning saying “check electrical.”i started to pull over on the freeway and my car went into “turtle mode “and I made it off the offramp but almost got rear ended. I was half a mile from home so I limp home in a tow truck towed off. It was determined it is the ICCU.”

“While driving on the highway during a rainstorm, the high voltage fuse on my car's Internal Charge Control Unit blew and the ICCU itself failed. This rendered the vehicle inoperable as soon as I managed to get it to the shoulder. It took two weeks to repair, and I had to argue with Hyundai's corporate lines for almost six months before the offered a partial reimbursement for their device failure.”

“The ICCU component failed. I lost propulsion while driving and almost got rear ended. The dealership service department confirmed the ICCU issue. The dealership service department has inspected the vehicle. I had a dead 12v a month prior that I had asked the service department to look at and test the ICCU. They did not test the ICCU. The car warned me 30 seconds maybe less before i lost propulsion.”

NHTSA complaint #11714329, filed 2026-01

“This vehicle's brake lights do not come on when using regenerative braking. The regenerative braking can bring this car to a complete stop fairly quickly and the brake lights should come on. Several near misses of people almost rear-ending me, and a few got mad enough that I feared a road rage incident. This after only owning the car for 2 weeks.”
