I have a 2008 Buick enclave cxl with 160k that has a few minor issues . First, there's an issue when starting, it doesn't make any indication that it's starting when turning the key fully. I'll make a second attempt and it starts. Second, when pressing the door lock switch on the driver side, I can hear a clicking sound but the doors doesn't unlock. I can press the lock button and itll arm the security system but my automatic start doesn't work. Lastly, my rear hatch closes down on me once I press the button on the remote to open it...please help.
