Thoughts ?

Just noticed this for the past 3 days.

1st time I noticed it, was when I went to the car, all the interior lights was on. Strange but started paying close attention.

On the last 3-4 times I had the headlights in auto, turned off the car and when I came back to it (headlight switch on auto), upon ignition, it would flash the hazards and turn on the interior lights. I just pressed both buttons to turn them off.

Last night, came back home, made sure I turned off headlights to off position, locked the car and upon immediate locking of the car, the interior lights were on again and stayed on. Unlocked, turned off the interior lights and all is well.

Whaddya guys suspect. Does it know the Polar Vortez is coming or symptom to the like. It's going to be a high of 61F and on Thursday, the low temp is forecasted to be 8F
