So far, I've been told it will be about $230 for the 10K service. They are also looking at the shifter issue (remember our I-15 day? I fixed it myself, but they will look at it too - no charge). There is also the upholstery issue. On the passenger seat, the panels started to separate a little. They do not fix it there (or just replace the seat). They send it out to someone else. That's under warranty.
The biggest surprise was that they gave me a loaner. I wasn't expecting that. When I brought the car in for the oxygen switchover sensor problem, I was told there are no loaners due to the lower cost of the smarts (compared to the Benz's).
They've treated me well so far. I don't know just where in the process the car is, but it's not as urgent thanks to the loaner they provided.
