Update 14-12-2021
This issue has been resolved and you should see the correct image of your Tesla car in the EEVEE-app.
It that's not the case it could be your car is in a sleeping state. As soon as it becomes active the image should be updated.
_______
EEVEE Mobility is directly connected to your Tesla car data and receives information via a direct integration. It seems Tesla has recently changed their car model codes which we use to show the correct image. Because of that a fallback image is being shown.
Our software engineers are analysing this and the correct image will be shown as soon as this issue has been fixed.
