Transmission Not Go Into Gear problems of the 2008 Smart Fortwo Cabrio

The transmission won't engage into reverse. Called for help. They had me reach under gear shift and release a cable to move car, after I did that I went to work and car wouldn't shift out of gear into park. Called and they picked it up to fix it, came back and I had no problem for a while and then it would shift but not lock into gear, rocked the car, pushed it and finally it worked, this is a repeat thing. I am having problem right this moment, I can't drive my car. I looked on line to see if there is a resolution and the internet is full of complaints of people having the same problem. Pages and pages of them. If this is an on going issue why has there not been a recall to fix all these cars? I cannot be the only complaint that came to you. There are thousands.
