Alternator/generator/regulator problems of the 2015 Chevrolet Suburban

While driving all of the power cuts off including power steering. Alternator, oil, fuel, struts, battery x 2 have been changed out in attempt to correct issue. Issue is still present. Local chevy dealership unable to rectify problem. There have been numerous incidents with potential accidents. There seems to be a power draw on the system, unable to find any kinked or frayed wires. While driving all lighting including gauges dims usually prior to complete vehicle electrical failure. I have a video of electrical dimming, but unable to load on here. Vehicle is labeled as 2015 but manufacture date is 2014, ive noticed there is a recall on 2014 models for electrical chassis failure however my VIN is not encompassed in this recall.
