My TLX does this thing, where if it sits too long it doesn’t start and it makes a ticking sound when trying to start. Power is in the car. So far I changed battery alternator and starter. Still haven’t found the issue.

Maybe you have a parasitic draw on the battery. Any new installs lately like webcam, radar etc? Any interior lights left on by mistake? Is the remote in your house close enough to constantly trigger the proximity unlocking of doors and lights? I keep my remote in a Faraday Box mainly for anti-theft but also it would not transmit the proximity feature if close enough from car from inside.
