Hi Lianne.
I had my previous, 2015 auto, for 3 years. Never a problem.
Except.... While away, on holiday. I checked it was all secure for overnight, parking.
Pulled the tailgate, and it popped to the second catch!
With the alarm blaring, loud. I had to walk back to the chalet, for the key.
I now make sure, the tailgate is properly closed......
