In addition to what’s said below, expect ANY accident which damages the battery modules to “total” the car.

In 2019, Elon Musk said replacing battery modules costs between $5,000 and $7,000. However, different Tesla models use a different number of modules per pack. For example, older Tesla models, like the Roadster and Model S P85, have 11 and 16 modules, respectively. While newer versions, including the Model 3 and Model S Plaid, only use four to five modules.
Considering this, expect Tesla battery replacements to start between $20,000 and $35,000. However, these prices could increase as they do not include incidental expenses (like other parts) and labor. With the most affordable Tesla coming in at $42,990 before rebates, the battery accounts for nearly half to 80% of the cost of the vehicle.
However, actual battery repair prices vary from what the CEO said.
A huge design flaw with Teslas is having the battery made into the car frame.
