Chrysler 300 electrical gremlins, keeps draining the battery overnight

I'm at my wit's end with this car honestly. My 2015 Chrysler 300 has developed some kind of parasitic battery drain that I've been chasing for weeks now. If I don't drive it for more than a day the battery is completely flat, and I've already replaced the battery twice thinking it was just bad luck with faulty units before realizing something in the car is pulling power when it's off. I've done the basic troubleshooting like checking for lights staying on in the glovebox and trunk but nothing obvious. These cars are known for having weird electrical issues with the TIPM module and I'm worried that's what I'm dealing with, which would explain why a regular mechanic couldn't find the problem. I need a shop that offers risk-free Chrysler repair Al Quoz area preferably, somewhere that actually has the proper diagnostic equipment to trace parasitic draws and module issues rather than just throwing guesses at it and charging me for each failed attempt. I've heard good things about Dynostar from a Mopar group I'm in, apparently they have the right scan tools to communicate with all the Chrysler specific modules which is crucial for this kind of fault. Anyone else dealt with a phantom battery drain on a 300 or similar Chrysler platform and can tell me what the root cause was, I've read everything from the radio amplifier staying awake to the heated seat module failing silently. Just want to stop waking up to a dead car.
