I have had my Taycan since Nov 2023. Since my time of purchase until 3 days ago, a full charge at 100% would be 280 miles in range mode. As of the last 3 days including today, at 100% charge I am showing 207 miles in range mode. This cannot be due to weather because it has been relatively similar the past few months and this is during summer. Is it possible there is an issue with my battery pack? If this was a gradual decline over a year or so I would think its just regular degradation but it my capacity has dropped by 27% in 3 days.

You likely have a failing cell or cells in your battery. I just went through this with my 2020 4 S. After checking the battery the dealer determined since the car was a 2020 that the battery should be replaced with a re-manufactured battery. Apparently the 2020 batteries have issues with their cells. That took a month. The new battery carries part number 9J1915100RX, no extension of the battery warranty unfortunately. This may also be covered by recall ARA4 in the US.
