2015 Acura TLX Headlights Blinking
I have an 2015 Acura TLX with about 50k miles. Sometimes when I start the car headlights will rapidly blink(all 5 LED lights, then 3 LED lights, so on and so fourth) - this has happened when the car is in complete dark or out in the full sun. Usually when I start the car in the garage during the day and back out into the full light they will quick blinking. But then again it has happened in the fully sun. 3 years ago when the electronics acted up I found the battery was not holding a full charge and replaced. So this time a few months back I had the battery tested, connections checked and the alternator test (twice for both) and everything was fine. For about 2 months it stopped. But it is back - with it an added feature now. I have noticed the temp controls - kind of fade in and out - and yesterday alone I lost my settings for temp control twice, not difficult to set them back up (I keep it on auto, and not sync'ed). No other warning lights at all. Any assistance would be appreciated. I am hoping someone points me to something I can specifically asked to get checked.

Looks like it was a bad sensor. It was doing something every 10 seconds that would drain the battery. This pulsing was also causing the side effects. Hopefully I have seen the last of the issue for a while.

Swing and a miss - was not the sensor took a week for the battery to drain again. Next visit they had the car for 4 days - thought they had it fixed - but nope another swing and a miss. Had to charge the battery today. So something is draining the battery while it is parked - but the good news is they reseated something and the headlights have not done the blinking on/off thing during the week. So time to call dealer again - at least the second visit cost nothing.

This just started happening to my 2019 tlx the other day.
the climate icons flash on and off the radio screen, sometimes the settings reset upon starting the car. Last night I started the car and it kept flashing between low beams and drls. I had to force the headlights on, instead of using auto.
battery was new when I bought the car 8 months and 11k miles ago. Has 45k on it.
it wil be going to the dealer in a week or so.
