What’s the failure rate on 2021 sr+ batteries?

[izzzyyd]

What’s the battery failure rate still in warranty for 2021 SR+? So basically failure rate of batteries < 100K miles

Also when get battery work done at Tesla and they warranty it do they warranty the whole pack or the specific modules they might have replaced?

whole pack. modules arent replaceable on teslas.

Failure rate is incredibly low.

Any articles or stats? When googling I couldn’t find anything just the typical filler articles of we don’t know blah blah

If replaced under warranty, you get the greater of the remainder of the existing warranty or one year, I think. If replaced out of warranty, there's a separate 4 year, 50K mi warranty.

Only Tesla would have any accurate statistics on the failure rate. The best other sources could do would be a sampling of as many owners as possible, and it would have a big error rate. Even if you did a poll on here and every single SR+ owner responded, that is just a tiny amount of owners out there. And it would skew the results if some of them joined this forum mainly to vent or seek advice or help on a battery failure.

Wwarranty repairs retain the remainder of the existing warranty, no extensions. (Even if there is only 1 day left on the warranty.)

Thanks for the correction.

When you replace a battery out of warranty do they give you an actual brand new one? Or a rebuilt one like in warranty?

Also would they change to the newest available battery tech like LFP?

No

You’re asking about 2-year-old batteries that are warranted for 8 years or 100k miles. There aren’t many that have failed in such a short time period.

This is is the answer to "why am I not finding this information somewhere online".

Well in general what is the battery failure rate of model 3’s in warranty and out of warranty. What’s the expected mileage they start having issues and require repair?

Changing the question slightly isnt going to change the answer from the one that is provided in post #5.
