What Kind of power issue is this?

One headlight turns off sometimes, sometimes AC doesn't work, sometimes acceleration is stuttering, sometimes auto light doesn't work. What could be the possible isssue? Is it the Alternator, ECU or a relay problem? Please help.  

Vehicle : Suzuki Huster : Model Year 2015

Internal mechanical and electrical base is the same as Wagon R stingray (2015 model)
