What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2009 Mercedes-Benz S, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

WE TOW A 2009 SMART PASSION CAB BEHIND OUR RV, AS ALLOWED BY SMART AND IN WRITING WITHIN ITS OWNERS MANUAL. TWICE NOW, WE HAVE LOST THE HOOD (OR AS SMART REFERS TO IT, THE SERVICE FLAP) WHILE TOWING. THE HOOD COMPLETELY DISENGAGES FROM ITS LOCATION AND BASICALLY FLAPS AROUND UNTIL THE CAR IS PULLED OVER TO A STOP. DAMAGE HAS OCCURRED TO THE HOOD, AND THE FIRST TIME WE IMMEDIATELY REPLACED IT AT A SMART DEALER WHO STATED IT MAY HAVE BEEN OUR PROBLEM DUE TO THE POSSIBILITY THAT WE MAY HAVE IMPROPERLY INSTALLED IT.. THE SECOND TIME IT OCCURRED (IN EXACTLY THE SAME MANNER) ANOTHER SMART DEALER TOOK IT TO THE MANUFACTURER WHO DECLARED THAT BY TOWING IT BEHIND THE RV WE HAD AN UNUSUAL AMOUNT OF TURBULENCE AND THEREFORE WAS NOT COVERED UNDER WARRANTY,NOR WAS THERE ANY 'FIX' FOR IT. MY CONCERN IS THAT THESE SAME TURBULENCE CAN BE FELT ON AN INTERSTATE BEHIND A LARGE VEHICLE OR IN A HIGH WIND. THEREFORE I FEEL THAT IT IS MORE OF A PROBLEM THAN THE MANUFACTURE WOULD CONFIRM. WE HAVE TWO OF THE SMARTS, THE OTHER ONE IS A 2008, AND THIS SITUATION HAS NEVER OCCURRED WHILE TOWING IT. *TR
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
