Advice please: changing 12 V battery

I have an 11/20/15 P90D. I have 38,200 total miles on the car. I had my 12 volt battery changed by Tesla (warrantee) after about 3 years, approximately 11/18. I just got a message that my 12 V battery needs to be serviced soon and the car won't get updates now.

I DID purchase the extended 4 year warrantee in 11/19 so I think it should be covered. I watched the service man take the battery out in 2019. Looks pretty easy though. The "extended" warrantee has a $200 deductible.

I assume it is covered so I guess I should just let them do it again. It seems 3 years is not a great lifespan for a battery.

Any other thoughts anyone has??

Thanks and Happy Holidays to all.

I don't think the 12V will be covered under warranty, given it's a wear and tear part. 3 years is about average, depending on use and charging behavior. Sometimes Tesla does replace under "warranty" but in my experience it was goodwill, hard to come by with them these days.
