Consumer Description

Had all previous open recalls for iccu performed. No previous warning in car. Driving unto free way. Loud noise like a tire pop. 12 volt low power warning on dash screen. Car began to lose power. Picture of a turtle shows up. Low power warning. Car lost power within 10 seconds. And couldn't accelerate. Extremely dangerous. Once completely stopped the car turned off and couldn't start again. Was able to get car to turn on with jumper cables by tow truck. But couldn't get to "start" engine. Dealership says the 12 volt battery and iccu needs to be replaced. They are blaming the issue on the fact that I had an aftermarket subwoofer installed and don't want to cover under warranty. Car ran fine with said subwoofer for a year prior with no additional changes. Have used same subwoofer and amp on multiple cars with no issue.
