I just purchased this vehicle from Hertz authorized dealer in December 2024, January 2025 the Electrical system, infotainment became non functioning. This caused my vehicle to stall, on star safety charge, etc to fail and not function. No communication within the vehicle that is an electric vehicle that requires this system for all components to function and provide a safe car to drive. Power to vehicle, back up camera, on star for emergencies, charging, this affects all the ADAS components in this vehicle to function properly causing a safety hazard. Took this vehicle into the dealer they diagnosed this system is down and no communication with radio. Also Set false DTC was completed. It is scary that a radio component can cause an emergency service to fail and other components in the vehicle to fail all electrical components in this vehicle. I am writing a complaint to Hertz since they stated all was okay when the radio, on star never worked, an update for the main system was no corrected and they failed to make sure the EV batteries were properly connected.
