Transmission Gear Indicator problems of the 2008 Smart Fortwo Coupe

I own 2 of the 2008 Smart fortwo automobiles (pure & cabrio). Both have periodically been balky shifters (stuck when trying to move the gear selector out of park). One has briefly refused to shift into any gear, independent of the gear indicated. Both have briefly refused to shift out of park. . . Until today when my wife was stuck in park at a red light. The abs light had come on, my wife decided to see if she could clear the indicator. She quickly put it in park, engine off then on, but vehicle remained stuck in park. A deputy moved traffic around her. I arrived & after repeated attempts for 20 minutes, it finally released from park into drive. I drove it home & thoroughly lubricated the shifter mechanism per posts on the Smart car of America forums. As I re-read this thread containing 4 years of contributors, there is an impression that the factory released a 1st, then 2nd generation of shifter replacement hardware. There is abundant owner feedback that there is a reliability issue in gear-shifting, at least on the 2008 model. Per my local dealership in st charles, IL, there is no factory recall for this issue. The dealership will run a $120 diagnostic, but repair is at the expense of the owner. Apparently, I am on my own to purchase updated shifter hardware, or self-maintain sufficient lube on the original, balky shifter hardware. If one ever pulls over in a remote or dangerous area & puts the transmission in park, he may be stuck there permanently, until rescued. In dangerously cold weather, this mechanical failure could be fatal. In traffic, this could have led to a serious accident. On what other vehicle would this behavior be tolerated? if 2 out of 2 of my vehicles exhibit this issue, it is widespread, & a danger to operators of this vehicle. I'm going to also report it using my other 2008 Smart fortwo VIN next.
