2023 Nissan Sentra STEERING,VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE

After 8 months of driving my car brand new I started experiencing multiple intermittent malfunctions in the dash board & infotainment system. I have documentation of DTC codes current in my ECU. These codes each dealership refused to find and instead replaced my car battery, wiping the codes & replacing my infotainment system after it completely failed. After repeated repair attempts each dealership failed to successfully repair under warranty & told me to drive the car as normal when these malfunctions continued. These electrical malfunctions were at one point affecting my alternator which I also have documentation of. The car has lost power yet the engine stays running while I am driving. My handsfree is intermittent everyday. I am now way past my warranty & extended warranty due to following dealerships advice to drive the car as normal and bring back. These ongoing malfunctions create unreasonable safety risk which I believe falls under 49 U.S.C. Chapter 301 — the National Traffic and Motor Vehicle Safety Act. A third party diagnostics shop told me my car would have to be taken apart to find the grounding issues as this is clearly a manufacturing defect. These repairs have cost me money and I refuse to keep paying these dealerships if they aren't willing to resolve the core problem. I get constant push back from each dealership. I've already engaged with Nissan consumer affairs, a Lemon Law attorney, and filed with my State AG, AG recommended while undergoing an IDR that I file a complaint here as well. Please help.
