Consumer Description

The Grid to High Voltage Converter A (GHCA) is a critical, often failing, component in 2025+ Volvo EX90 and Polestar 3 electric vehicles that converts AC grid power to high-voltage DC for the battery has failed 5 times in my car with no fix from Volvo in the foreseeable future. There are some reports on reddit/ex90 and other owner forums that these failures can cause unsafe voltages and have blown up home chargers. It seems like it is getting to the point where they need to be forced to issue a recall for this part and compensate owners.
