After pulling car into garage found that shifter would not move past neutral from drive position. Though ignition key could be turned far enough counter-clockwise for engine shutdown it stopped short of being able to be removed. After problem diagnosed repair required complete replacement of electronic shifter module costing over $1,000. I found multiple complaints for same problem on google from other mercedes owners. Fortunate that failure happened in my garage. If episode happened on open road major incident could have occurred. I did contact mercedes cac (customer assistance center) to report problem both by phone & letter. Their representative offered only excuses & indicated failure was result of 'normal wear & tear' that should be expected in vehicle 10 years old regardless of how well maintained. At age 63 I have owned many cars in my lifetime & none ever had such a failure. I am original owner of this vehicle purchased new & well maintained.
