You can switch the wing mirrors off using your iPhone, plus you will still be able to sett and control your charging using Mitsubishi phone app.
Our local supplying Mitsubishi were less than interested as they were due to change to MG, Mobility informed I can use another dealer, unfortunately there is a world wide shortage of screen assembly’s, personally I would just carry on as per normal years ago we never had all these option/devices it just inconvenient, it will not affect the major components of the vehicle.
If you feel unsafe you should make it quite clear both by email and phone you have lost confidence in the vehicle.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
