Complaint Summary
ELECTRICAL SYSTEM
Owner Narrative
On the morning of January 23, 2026, the ICCU Assembly and fuse failed when driving on a freeway in moderately heavy traffic. I was driving about 55 mph when I heard a pop from somewhere behind me. A warning message came on the display to check the electrical system along with a battery symbol. The car lost power. Losing power like that on a freeway was not at all safe. It could only go about 25 miles per hour. I had to drive on the shoulder of the freeway with my hazard lights flashing until I reached an exit ramp to get off the freeway. I parked on a side street in a residential area where I felt safe, turned off the car, and waited. I turned it back on. The message was still there so I called for a tow. The 12-volt battery was completely dead by the time it got to the dealers and had to be jumped to be able to park it. The original ICCU had already been replaced in November of 2024, so this was a failure of a replaced part. The car was at the dealer for 19 days before it was repaired due to the wait for the parts to be shipped. What component or system failed or malfunctioned, and is it available for inspection upon request? The ICCU and fuse failed but I don't have the part since it was replaced by the dealer. How was your safety or the safety of others put at risk? Losing power on a freeway when cars are traveling at high speed is not at all safe. I could have been rear-ended. Luckily I was able to get to the freeway shoulder without incident and travel on the shoulder to get to a safe place. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. They diagnosed it and replaced the failed part. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Unknown. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. The warning message popped up at the same time as the loss of power.
