gear shifter locked in park and would not engage

On a random day, I was leaving for the office only to find that the gear shift would not move out of park. This was very frustrating as I had a meeting scheduling for first thing that morning. I called my husband who thought maybe the emergency brake was stuck. He left work and came home to see what was wrong. He couldn't fix it. The car had to be towed. The folks who came to tow the car dragged it and scratched the concrete in our driveway which we were never compensated for. Come to find out, there was a recall on something that impacted the gear shift. The dealership finally fixed the car after several weeks and a high car rental bill. Thanks Mercedes!
