my car is a year old, I have a smart 42 passion, black with silver. black leather pkg. sometimes when i park the car and then I get back in it and put it in reverse, there is no reverse. I have to turn it off and start all over again and some times that don't work. It has happened about 5 times now in the past month. never a problem before this, I have 13,000 miles on it. and had my first oil change. whats with this.?
