Tesla mobile service replaced the taillight for me in February for the condensation issue. Unfortunately, the issue occurred again after a recent storm in Oct. When Tesla mobile came out this time, they would NOT replace the taillight, and noted in the invoice ‘provide customer education‘. The only education provided, was yeah this issue occurs, but the tech mentioned this issue may be resolved with newer taillight part with better seal and I should try setting up a new service appointment. We’ll see what happens now. Two other services were performed, reseal front upper control arm ball joints and replace clips in the interior trim.
