This vehicle is a plug-in-hybrid. It should not be able to move while plugged in. Problem is attempting to move the vehicle when the charge cable is still attached and the vehicle is on an incline. Subaru does not display a warning message - instead it displays "check engine" and an ambiguous symbol (a red steering wheel). Subaru disables the power to wheels that would have enabled the driver to close the gap to the charging station. Instead the vehicle rolls away from the charging station, breaking power plug at the vehicle port. Even placing the car in Park does not prevent damage, the car will roll down hill until the Parking gear latches. I have now broken my power plug 3 times. I am a professional electrical engineer. This should not be able to happen Subaru should prevent the car from being able to move if the cable is still attached, and instead display a message that the cable is still attached. With the "check engine" message, I engaged my OBD diagnostics and it could not find a "check engine" flag. At this point, I put the car in gear, and even through Subaru disables power, the car then passively rolls down the driveway, breaking the cable at the power port. Instead of the ambiguous "red steering wheel" icon - Subaru needs to lock the car in Park and display a real message. When you finally turn the ignition off - Subaru displays a huge "Goodbye" message on the auxiliary display. I say finally because if you do restart the ignition with the cable attatched - you will not be able to turn off the ignition - only after exiting the vehicle, disconnecting the plug will you be able to turn off the vehicle. Not being able to turn off the ignition should not be permitted. Numerous errors in the control logic.
