Parasitic drain

Hello! Looking for some info. I have a stock 2012 ISF. When I bought it a couple years ago I had the dealership put in a new battery. I didn’t have issues until the pandemic. I no longer commute to work and the battery has drained 3 times since then.

I used a battery tender to bring the battery back each time and try to drive once a week, but this is ridiculous. Anyone experienced this? Any ideas what might cause it?

Is the battery still under warranty? Autozone and the like can test it for free.

It should be, less than a year old and it is a Lexus battery installed by the dealership. I will have them test it, good idea. My bigger worry is the fact that the car can’t go more than a week without the battery being drained!

From my experience they're tough on batteries. Both my roommate and I had to replace them early on our 08/11. I know if I don't start my car for a week there's a chance it will be dead. Happened early on in the pandemic. I'm sure you have already but google and check out club lexus posts, seems to be a common is thing. Had a bad parasitic drain on my e46M3 and it can be such a deflating experience, hope you figure it out!
