Engine Burning Oil problems of the 2009 GMC Acadia

I go through headlights every 6 months this last time, my driver side headlight got replaced and two days later it went out and the glass was shattered. I went and got new bulb and it did not work, after inspecting the the wiring we noticed it was burnt up and need replaced, GMC said it's on us. We have spoke with GMC about our engine burning oil which they are well aware of and the dealership tried to help but GMC refused to do anything my car send a signal telling me to turn off the car or starts miss firing every which way and gives codes saying I need new coils which is not the case. The air bag light goes off saying that there is someone in the passenger seat because the calibration get off, it took mcdaniel's to figure it out the other dealership blamed it on electronics. The windshield wiper fluid no longer comes out properly and needs something replaced so that it will go up on the windshield.

I leased my 2009 GMC Acadia almost 2 years ago, it has been a nightmare. I bought as is so dealer would not return my calls that had anything to do with problems. First, not even 3 weeks after I leased the vehicle the electrical system started to go, my driver window stopped working, my back hatch well I can't even open it because there is no key to open nor is there a button anywhere the mechanics said I need to take it to an electrical mechanic. . . Wonder how much that will cost?, my stabiltrak system constantly flashes. The engine burns up too much oil even after an oil change within 3weeks I need to put oil, I do not drive far nor alot. To work and back. It will cost more to fix this truck than what it is worth now I'm stuck with $5,000 left on a vehicle that is a piece of poop. When I drive the truck pulls as if the engine cannot get the truck going. I can't turn off the truck while putting gas because the vehicle wont turn over once the gas has been put in and started. The mechanic said its the trans evap system. I dont understand how GMC can get away with manufacturing vehicles like this with no concern for the customers.
