I have a 2016 Cruze limited manual shift. Have been trying to figure out trunk release for a while. Today finally figured out a combination of steps to open after I've disengaged the parking brake. First step was I put it in first gear, applied parking brake, unlocked doors, and before I could hit trunk release my kids had opened the back door. The trunk opened though. Tried again with other back door it worked again. Then tried the driver's door and no it wouldn't open. I'll keep trying other combinations like passenger door then having it in neutral. I do know previous owner did have some damage to trunk and front end. Right now the driver's window isn't working and we had to get the window closed so somethings may not be fully connected until we fix that. I'm still wondering if the trunk's actuator was replaced with wrong part too. We've had to do some repairs and with it being the limited edition even the windshield wipers are different. I'd love to know why it's working oddly because owner's manual only says important step of the parking brake applied. That only works sometimes before it is disengaged.
