I don't think this is a right to repair issue, seems more like a liability issue. If Tesla fixes the battery pack and the fix fails, making the battery pack fail (or worse, catch on fire), they are on the hook to repair or replace your car. If the independent shop makes a bad repair and it fails, then Tesla will say "That part was unrepairable, you shouldn't have tried to fix it".
