Tire pressure sensor & auto headlamps malfunction after window tint

Hello, bizarre situation here and can't determine if they all might be related. Last week I had my windows tinted and while the car was in the tint garage, I noticed the inner lights were on even though the car was off. Since then, the dash typically tells me to switch off the lights even though the switch is set to auto. I've checked outside and the inner lights are indeed on. As soon as I move the switch to the off position, lights go off and message goes away. If the drive is entirely in the sunshine and I park in the sun, the lights don't turn on and I don't receive the message.

Second, my tire pressure indicator is now telling me about 50% of the time to correct the tire pressure. Have checked all 4 tires multiple times, all at the correct pressure.

Any chance these two issues are somehow related in the complex computer control systems? Does the window tint have anything to do with the sudden auto headlamp malfunction?

Did you tint front? There is an ambient sensor in middle upper section of the windshield behind your rear view mirror. That area shouldn't be tinted. Not sure abound your yire pressure. Maybe need some reset or needs some air.

They didn't tint the front windshield which is why I'm baffled that I now have this random issue.

Think about what you said----you darkened the interior with a goof ball tint----your interior lights are on auto--the lights come on-----turn the lights off and the interior lights go off------NSS----the sensors are working to design.

Your problem is that you chose the wrong dergee of tint!!

Plutoe, I should have been more descriptive in my original post. It isn't the interior lights, I'm referring to the inner headlamps just next to the grill on the exterior of the car. Those are the two lamps that are remaining on. Interior light are functioning as normal.
