Plain and simple. you have an air leak in your suspension!as your buick is running a compressed air system for the rear suspension, overnight while the compressor is not running the air is leaking out of the system untill empty causing it to be low in the mornings. once started in the morning the compressor fills the system with compressed air and all is good untill the next night. Iwould be taking it to a suspension specialist to repair the leak before the compressor gets overworked and burns out.
