I'm sorry to hear that, I've had issues with necks on MIM Fender Precisions, I had a 2017 and 2018 that I had to return for refund (Fender refused to fix or replace either). Being that is a new bass, you may have to contact Fender to see if they will directly fix or replace it. If you want to go that route, you can take it to any Fender authorized service center in your area, with receipt and they'll fix it if it's possible or try to get Fender to replace it. Other option is maybe get a refund from where you bought it.
Sorry again, I know from experience how frustrating and a let down it is to get a new bass and it turns out bad.
