Owner report 10366634 · 2010-11-17 (November 17, 2010)

I OWN A 2009 MERCEDES BENZ, MODEL C-300. THE ISSUE IS THE LOCATION OF THE CRUISE CONTROL ARM ON THE LEFT SIDE OF THE STEERING COLUMN. IN AMERICA CARS THE TURN SIGNAL ARM IS IN THAT SPOT ON THE TOP, IN THIS CAR IT IS ON THE TOP. SO IF YOU REACH FOR THE TURN SIGNAL ARM YOU TOUCH THE CRUISE CONTROL ARM FIRST BY MISTAKE. AS SOON AS YOU TOUCH THE CRUISE CONTROL IS ENGAGED AND STATS TAKING OVER. A VERY GRAVE SAFETY HAZARD. *TR
