Opened it last night and the actuator sounded horrible. Sounded like a grinding noise when it was actuating. Closed the tailgate and tried it again only to get the same noise. We were heading to dinner so I just closed it and we went about our night. When we got home I went to open the tailgate to get some groceries we put in there earlier out but now it won't disengage. Tried the button on the tailgate and remote. Also the top section won't unlock either. We have a warranty on it but the dealership won't be open till Monday and it's nearly impossible to make it to them during the week. Was wondering if any has had the same problem and if there's a simple fix or is the actuator most likely shot.
