Check Engine Light On problems of the 2014 Nissan Juke

Electrical issues began within months after purchasing (Dec 2014). Navigation system, radio, interior lights all go haywire unexpectedly. Radio//navigation completely black; interior lights either stay on, flicker or won't come on at all. After taking it back to the dealership & having them test it, they always claimed their computers didn't catch any issues. I requested that my complaints be marked down & sent in to manufacturer every time. That began happening before 20,000 miles and continues today (115,000 miles). The car has never thrown any codes & never had any check engine lights, or any such mechanical issue light notifications come up on dash. The car began losing power around 75,000 miles (oil changes, maintenance done on time)�when accelerating the car would skip, jump or almost stall whenever trying to pull out in traffic. Changed spark plugs at recommended mileage (100,000), no change. One day after driving to the gas station which is 4. 2 miles from my home & back home, when mileage was around 100,000 (conveniently immediately after warranty expires) my cars a/c quit working, and the car ran incredibly hot (with absolutely no indication of any issues). I noticed my feet were burning under the driver side dash (while driving). Pulled over, popped hood-immediately saw coolant reservoir (plastic reservoir) was empty, checked oil dipstick and nothing�no oil. 3 days prior to this situation I checked fluids (in south georgia during the be summer it's incredibly hot & I was taught to keep an eye on oil/fluids during extremely hot weather. I had an oil change roughly a month prior to this situation as well. After this overheating problem was resolved, my a/c no longer cooled. Recharging did nothing�due to the perfect timing of the warranty expiring that left me with no alternative other than accept my fate & the unbearable georgia heat.
