Rear Passenger Door Won't Open From Inside

On my 2014 QX50, the rear passenger door won't open from the inside no matter what I seem to do. It does not seem to matter how the locks are configured on the car (if the child safety lock on or off), no matter what I do, I can't get that door to open from the inside. The driver side rear door opens just fine from the inside. The rear passenger door will open just fine from the outside, but it just won't open from the inside no matter what I seem to do (whether I manually unlock it, whether I automatically unlock it, etc.). This would not be such a big deal, but it is going to cause some real problems for me when I have to do dropoff at my daughter's school (because she can't exit the car on the passenger side). Any recommendations?
