Many Prius drivers have reported the most common cause for a red triangle light is an issue with their battery. Typically, the codes that come up after a diagnostic are P0A80 and P3000. The P300 code refers to the Prius' battery control system. When this code appears, the problem is typically caused by several sources, but it means there is an issue with the HV battery's ECU. When it reports inconsistent battery or cell temperature, a red triangle of death will be displayed and a P0A80 code is present. Although the hybrid battery pack has 204Cells, it only takes 1 failing or bad cell to cause the code and it means the battery is on borrowed time.
