I placed the car in park when I got home from work went inside my house for a few minutes came outside, when I turned the car on and tried to take it out of park it would not change gears. I tried it for almost 20min. I had to turn the car off and back on a few times for it to work. It does it almost everyday. Yesterday 09/14/2011 I had to drive the car away from my job due to an emergency and it would not change gears. I tried after 10min and just left the car behind and had to get a ride from a coworker. If this was a life or death situation I would likely not make it due to this safety issue. This is an ongoing problem.
