Lift gate erratic after recalled

My 2020 cx9 was recalled for the lift gate. After recall was completed it has worked erratically. Sometimes it only opens a couple of inches, then pressing the button again opens a couple more inches. Also, I experienced something that I thought would never happen. I got out of the vehicle with in running and the key was left inside. The doors locked. It happened in my driveway, so I got my other set of keys thinking they would open the doors. They did not. I am taking it back to the dealer to be checked. HAS ANYONE HAD ISSUES LIKE THIS?
