Can't find "Vehicles" in Apple Maps

At one point I had my Porsche Taycan added to Apple Maps. Maps was able to read my battery charge. Then it stopped and constantly told me that my mileage was no longer accurate and it hadn't been to read the mileage for a number of days. I re-connected my phone to the Taycan. I deleted the Taycan from Maps. Now I'm trying to reconnect the car to Apple Maps, but there is no "Vehicles" in Apple Maps. I have made sure that location services on the iPhone are all on.
