I have a bit of a odd situation. My son’s backpack strap got caught directly in the lift gate lock on my 2018 CX-9 Grand Touring. I tried popping out the panel and manually releasing the latch as per the user manual to no avail. When I click the remote I get the double beep, the mechanism starts and then stops. Any suggestions other than dealer? Really stuck without car and can’t afford to leave at dealer for any period of time. Any advice welcome. Thanks!
