I have had my Mitsubishi Outlander PHEV owner since late 2014 with no real issues.
A few weeks ago a couple of 'EV' and 'ASC' service due errors appeared on my dashboard - they didn't stop the car running and they went away after the car was restarted. Coincidentally I had a full service booked a week later and asked the garage to check it out but they could find no error codes registered.
Then two weeks later (last Friday) I went to start the car and had three full 'service required stop safely ' messages on the dashboard, for 'EV', 'ASC' and 'Brakes' and the car wouldn't start. No amount of switching on and off the car would clear these. I called out the AA who diagnosed a problem with the auxiliary lead acid battery as it was on its last legs (down to 9v) and they replaced that. No warning had appeared on the dashboard about the auxiliary battery at any point but interestingly the AA Car Genie I had in the diagnostics port had told the AA about it - so they AA turned up knowing the issue and having picked up the correct battery on the way. Once the battery had been changed then all the other messages cleared and the car started fine and has worked happily for days since.
Sounds a bit of a design fault to me. Something that may only now be appearing as the earlier cars now begin to need new batteries. Firstly the dashboard console should tell you when the auxiliary battery is dying and secondly there were a totally inappropriate set of scary warnings that could result in un-necessary worry and behaviour!
