2015 Acura TLX Parasitic Battery Drain

For the last year and a half my 2015 acura tlx has had issues. The last time I had electronic issues in 2018 I replaced the battery - all was well until beginning of 2022. Then auto headlights started blinking when I started the car, sometimes seat would not auto adjust, and sometimes lose my temperature settings. This went on for months then when it got really cold the car would not start - so I replaced battery. For about a month all was well, then it all started happening again - then a week or so later dead battery. Charge it and all is well for a week. So I took it to acura dealer. First time in they found the light sensor was bad. Ordered part and thought they had it fixed. Nope - 1 week later battery was dead again. So took it back for a second visit. They had it four days - found a lose connection on the lights, reseated that and blamed the drain on the battery from lubrication between the two terminals. I did explain that the batter was only a couple months old and it does not explain before the newest battery. So after reseating the connection the lights did not blink on and off since last monday - but get up today and had to charge the battery. Seems like it drains the battery just enought to keep it from starting - but it has enough juice to retain all my settings.

So bottom line on what they see - is a constant pulse hitting the battery every 10 seconds or so. I have never driven very much - the car only has like 56k miles. So it has only been the last year and a half that I really saw the issue. I was searching this forum and saw that the HFL(Hands Free Link), or bluetooth, can cause the problem - seems to be one of the main reasons, but maybe their are others. Before I picked the car up they said they went thru plugging and unplugging all the components and continued to see the drain. Cleaned the terminals and supposedly the drain when away. Now I wonder if they actually unplugged the module. I was wondering if the drain could be sporadic by the HFL module? I know that I have not had any issues with blue tooth, but only use it with my new apple phone right now. I know it will connect to my phone from my detached garage when I start the car - only when i get down the driveway to the street when it disconnects that I know I left my phone in the house. Got to confirm this is the issue first.

Going in Thursday to get them to disconnect it (they will do that for free) to see if it fixes the problem. If it is will get a quote to fix it - but from what I read the part is expensive for a 2015 acura. Anybody know if the replacement parts are any better? Assuming this is the issue.
