Oh, Boy, was I embarrassed. I have a car with the stupid temporary tag on it, and I can't get in the next morning after purchase. I took it back and it was fine at the dealer. A few days later, it happened away from my home and I had to walk in the summer heat in AZ! I took it back again. It was fine at the dealer. I could only get them to change the key fob batteries. Two weeks later, I could get into the car just fine, but it would not start!! I tried contacting the dealer for 3 days before I used my AAA for a tow to the dealership and left it there. Of course it started at the dealer! They reluctantly checked it and replaced the Trans Range Sensor.
