Consumer Description

I started my car and after a minute I received a warning saying to check my electrical system and safely pull over. After 5 minutes of trying to drive to the dealership the car suddenly slowed down to a max speed of 27mph and then shortly after slowed to a stop and turned off. The car would not turn on and eventually the 12v battery died. I tried to jump the car but the 12v would not stay charged long enough to put the vehicle into drive. It appears the ICCU is not working and cannot keep the 12v charged to make the car function .
