Cost of Driving an EV

What I'm saying is you buy a new Tesla with a warranty on the battery once you change it out you no longer have a warranty because you swapped it out. So now you have a new car and voided the warranty.
If the battery fails while warranted by Tesla, & is replaced by Tesla, it will not void any warranty.....ANY work...even tires will void the warr tho' if not perf by Tesla, which violates the Right to Repair act..(Magnusson-Moss)..if I'm not mistaken..
