I noticed a few days ago that the electric vehicle (EV) is no longer engaging even when I am not running the AC or any of the other
things in which you cant use if you want that part of the car to engage.

I took it to the dealership where I bought it (not subaru) and after two hours they couldn't figure out what is wrong with it or why that part no longer works. They recommend that I take it to a subaru dealership. I have an appointment to go, but even calling and speaking with them I am not confident they understand my problem.

Before I go to another dealership I was wondering if anyone else has had a similar problem or what I should do?

Has it been a gradual degradation over time or was it a one and done (e.g. worked one day and not the next)?

If the latter:
- It could be a major relay fault or blown fuse
- An electrical connection came loose

It just happened at once.. I read something else that it could possible be the battery for the hybrid part of the engine? But it looks as if the hybrid part is working according to the display in the car, but it will never go into EV... Does that have anything to do with the start/stop function?

If it were the battery, it would likely have been a gradual thing. Working one day and not the next leads me to believe you've got an "open" circuit somewhere caused by a bad relay, blown fuse, cut or disconnected wire, etc...

Just to rule out the start/stop battery, get the battery tested. It's a simple matter of just hooking up a tester and pressing a button (takes about 5 to 10 seconds at most)

 

[SubaruXVHybrid2015]

Subaru XV Hybrid has 3 batteries fitted in the car. The hybrid battery is in the boot of the car, the Start/Stop battery is in front of the drivers seat and third battery is in front of the passenger seat next to drivers seat.

Check the Start/Stop battery and the other battery apart from the Hybrid battery. The EV mode on my Subaru XV Hybrid 2015 (Japanese) model had stopped working for more than 2 months and 3 days ago, two lights which indicate "Hybrid system fail" and "EyeSight" starting showing on my dashboard. I got the 2 batteries under the bonnet checked where the Start/Stop battery had failed and the other battery was showing a weak status so I replaced them both at a total cost of $465.00. Within 5minutes of replacing these batteries, the EV mode starting working and even better than when first bought it (imported from Japan 1 and a half years ago). I asked around out 3 different places for checking out the battery status and the replacement cost and one thing all battery specialists advised was to replace both the batteries under the bonnet at the same time and not just one.

Try this before trying anything else as the Start/Stop battery in this model is apparently notoriously bad after about 4 years of use.
