I'm wondering if anyone else has experienced this problem with the MDX auto locking system. Yesterday, I parked the car and took the keys out of the ignition, I put them in my purse which was on the passengers seat next to me. I then got out of the car and proceeded to get my kids out of the car. Once the door closed, the car automatically locked and locked my children inside the car. Fortunately we have a relative near by with a spare key who was able to help very quickly, this has happened once before and I had just assumed that I had erroneously hit the auto lock button, but now I am not so sure. I am planning on taking the car in to have it checked out but would be curious if anyone else has experienced this problem.
