It is a common occurrence on all vehicles with light sensing diodes on the dash. It can not be avoided if you are using a darker film (3M 50% Color Stable) on the windshield. You can avoid it by going with 3M Ceramic 70%, 3M Crystalline 70% or lighter on the windshield if you are strictly wanting heat rejection.
The consequence with going darker is the headlights will turn on more often and the dash lights and radio will dim more often if you have the automatic headlights feature on. This feature can be turned off on most vehicles. It occurs mostly around dusk. Not really an issue with many of the new LED headlights.
