I would start out asking for the revised tail lights. Don't hesitate to emphasize that we are talking about something BURNING OUT and any fear you may have for a firs in the ass of your car (actually a near impossibility, but it never hurts to make a case). I'm saying this because, even without my mentioning it, the SA was using what sounded like corporate talking points to reassure me about that.
There isn't anything wrong with the taillight assembly itself, it would be a waste of time to replace the whole unit, unless the connectors are rusted or corroded.

This issue is due to a lack of ground polarity for incandescent bulbs and the only fix is a new bulb holder and revised socket to accommodate the supplementary ground offset.

If you're DIYing it, you could even possible add additional ground yourself and not even replace the bulb holder and wiring. But since there is still warranty coverage, may as well let the manufacture own up to their shortcomings.

You can demand whatever you want from the dealer but if they don't see it necessary to replace the taillight unit, they won't.
