My vehicle locked after shutting the back passenger door. I just placed my son in the car seat and buckled him. I shut the door and walk completely around the car to open front driver's door. Before I could open door, the vehicle locked itself with my son, keys, and phone inside. It was 94 degrees outside and humid. We called for help and tried to slide antenna in to unlock. After contacting the dealership, garrett said that this is an ongoing problem and the new parts may not fix the problem.
My wife had just stepped out of the vehicle after putting the keys in the ignition and walked inside to grab something from her parent's house. When she returned the doors had automatically locked her out, she had to call a friend to bring an extra key. Luckily she didn't have our daughter with her or she would have been locked inside. We just figured it was an automatic anti-theft program, but didn't realize others were having problems. From now on, we just make sure we have the keys on us, or roll the window if the vehicle is still running when you step out of it even just for a second.
