Failure to shift out of park into reverse. Gearshift moves but gear display goes blank and chime sounds. Sometimes it will go into drive. It may be a solenoid problem. Very frustrating and it seems to be getting worse over time. I now have 38,000 miles on the car. This issue needs to be looked into. I expect better out of damlier benz.
