2018 Land Rover Discovery Electrical System

Car went black (all systems shut off) and i started to roll in the CVS parking lot when i was trying to drive in and Park. The brakes and nothing was engaging. IT happened so fast I was able to stop the vehicle and I am not sure how but may have just turned the shifter from drive to park... I took the vehicle in for service (a number of issues) and i forgot to mention this, I was told the Ground Stud needed replacing and it turned out this was likely the cause (I believe he said it had come loose). I have a extended warranty that has comprehensive coverage with CNA and they denied this part. Also, Land Rover recalled this exact part on 2019 and 2020 vehicles, clearly my 2018 has the same issue. Makes me wonder how many other 2018 vehicles also have the issue?

THE KEY FOB IS CONSISTENTLY HAS ISSUES WITH STARTING THE VEHICLE. KEY WILL NOT UNLOCK DOORS WHEN TOUCHING THE HANDLE. VEHICLE WILL NOT START WHEN PARKED. THIS IS UNSAFE BECAUSE I HAVE BEEN STRANDED IN PUBLIC PLACES IN THE COLD AND THE VEHICLE WOULD NOT START. THE DEALERSHIP WAS ACTUALLY NO ASSISTANCE. CHANGING BATTERS DID NOT WORK. REPROGRAMMING KEYS DID NOT WORK. THEY PROMISED TO ORDER A NEW KEY FOB, AND THEN THEY SAID IT WAS BACKORDERED. I FELT LIKE THIS IS A LIE. THEY HAVE STRUNG ME ALONG WITH NO RESOLUTION. I HAVE PROVIDED FOUR SERVICE RECORDS TO SHOW THE AMOUNT OF TIMES THE VEHICLE WAS TAKEN INTO THE DEALERSHIP ABOUT THE VEHICLE NOT STARTING FROM KEY FOB NOT BEING RECOGNIZED.
