My Ioniq 6 Limited AWD experienced a phantom braking event in a covered parking lot with no cars or pedestrians anywhere near the front of my car. The car just stopped suddenly with a warning message "Emergency Braking", and it wouldn't allow me to proceed until I turned off the car and then turned it back on. Fortunately, there wasn't a car close behind me at the time, but it could have triggered a rear end collision. Prior to this phantom braking incident, but on the same short drive, I noticed that the car incorrectly showed a red line in…

Luckily, the car was parked in my driveway when this occurred. If the car was in motion when the ICCU failure occurred it would have been very dangerous. The car cannot be driven. The car's system shows Hyundai Diagnostic Trouble Code (DTC) P1A906. The problem has been confirmed by a dealer. A new ICCU has been ordered.

I was driving, there was a loud pop, then warnings popped up on the dash and I lost power. I was able to limp the car back to my house, because I had just left. I assume it is the ICCU. I’m reporting this because it is a known issue that Hyundai has not seemingly been able to repair. With the pedal to the floor, I got up to 25 mph. Luckily, I was near home and not on a highway.
