Hi .I have a 2017 BMW x5 40E 52k miles
At last May I had 49k miles. My hybrid battery was dying and air conditioning performed poorly.
I started to diagnose with Ista and got the fault of replacing the battery cell module.
Ista shows the current battery health is 64%
I send to the dealer and after waiting 4 month they finally replaced it.
In the invoice I saw that 2 modules had been replaced and the dealer told me that car according to specs.
I recently started to experience that when I drive and battery shows that 50% max drive is not available even though I was driving on ev only
I started to troubleshoot the battery again and battery shows me 67% .
Also I have pictures with Ista diagnostics I can upload as well if necessary.

I am looking for any suggestions on what to do.
Go to the dealer and check the system again?
Change AUX battery ?
What do you guys think?
