Disturbing Mitsubishi Outlander PHEV characteristic

I bought a 2013 Outlander PHEV a week ago. On the two hour drive between the city I bought it in to the one I live in, I had a brief taste of what became a major problem this weekend. For no apparent reason, despite putting my accelerator foot down, the car would slow down. I had to stop and restart the car which seemed to cure the issue. Fast forward to this weekend. Again, I was on a cross-country highway trip. The car started doing the same thing again, but this time, the engine shut down and lots of warning lights came on. I actually thought the car had an overheated transmission or something like that. I gave the car a rest, restarted and drove off, only for the same problem to come back shortly after. So I Googled the issue. Turns out, I was completely wrong. Even though the car is a hybrid and I had a full tank of gas, if the battery is depleted so much on the open road, it will fritz the car's electrical supply and force it into limp mode. Before you reach zero on your battery level, you must put the car into 'battery save' mode. Firstly, this is a shit design flaw. The car should automatically invoke save mode if it calculates the battery is heading for zero. Secondly, is there a way I can set a threshold for the care to invoke save mode?
