Electrical, Doors will automatically lock and unlock most times lock and locks me in the vehicle having me have to climb through the windows and having to leave my windows open or locks me out the vehicle and can only get in by climbing in the trunk. Testing has been done and brought to GM to figure out the issue, and they replace the computer in it but still has the problem. I have had shops tell me these are all huge issues that needs to have a recall because my vehicle is not the only GMC Acadia that does all this. How is any of this safe for me and my kids.
