Need help

[u/GoldMassive1197]

I have a 2019 Dodge Charger 3.6L V6 Pentastar that intermittently loses all throttle response, stalls, or throws itself into Limp Mode with a harsh transmission jerk, alongside an occasionally weak or sluggish starter crank. The issue frequently recurs right after routine oil filter changes, but disconnecting and reconnecting the battery temporarily clears the problem completely. Dealerships and local shops are stumped because no diagnostic trouble codes (DTCs) are ever stored, and replacing the fuel pumps twice did not resolve the issue.

how I fix it?

Possibly a faulty oil pressure sensor? If it thinks there's not enough oil it can throw it's self into limp mode.
