After reading about it for months and putting almost 3k miles on my Mid February Smart Pure, it has happened to me.
Saturday afternoon brought the first symptoms. Intermittent problems getting into D or back to P. 1:00 am Sunday morning the Mrs and I were leaving our favorite watering hole only to be locked up by the famous gear shifter problem.
In re-reading, this looks like a very common problem. While it is not a safety problem, so it wouldn't be covered by an NTSB Recall, this surely seems like a problem that needs some proactive correction.
My Pure had to sit all night before a tow truck, arranged by Smart Cust Service had arranged. As of this afternoon, the car has not arrived at the dealership.
Tip to Penske and the Smart people. GET THIS FIXED. Bring people in and fix it. This is too common a problem and it will lead to bad feelings.
I hope to hear something today - if my car ever gets to the dealer.
