Hi Does anyone have problems with the child locks on the rear doors? Took my son and granddaughter out,first time with someone in the back. I turned the red button on the doors, as handbook. Checked doors and opened fine. Parked car and remote locked it. Rear passengers got back in but could not get out at next stop. Locks had reactivated somehow. I have tried several times to turn the red button and it works fine until I lock the car then it goes back to childproof mode. Am I missing something?
