Percentages are of component mentions. A single complaint can name more than one component, so these do not sum to the total complaint count.

That does not guarantee a specific vehicle is unaffected — recalls are issued against VINs, and new campaigns are announced regularly. Check a VIN on NHTSA.gov.

THERE IS A GLASS ROOF PANEL BETWEEN THE WINDSHIELD AND THE SUNROOF. THIS GLASS PANEL IS EXTREMELY BRITTLE AND SHATTERS EASILY. THIS IS MY SECOND TIME HAVING TO REPLACE THIS GLASS PANEL. IT IS A DEALER ONLY PART AND COSTS $960 PLUS $300 FOR INSTALLATION. THE COST OF THIS GLASS PANEL IS EXTREMELY HIGH. BOTH TIMES THIS GLASS PANEL SHATTERED, NOTHING HIT IT. IT APPEARS AS SMALL CRACKS AT FIRST AND THEN SPREADS. BECAUSE IT IS SO BRITTLE, IT EVENTUALLY SHATTERS. THERE IS A RECALL ON THIS SPECIFIC PART WITH OTHER MERCEDES MODELS BUT NOT THE C250 FOR UNKNOWN REASONS. PLEASE ASSIST.
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.

To enhance the satisfaction of our customers, avoid further costs of litigation and return focus to its core businesses, Mercedes-Benz USA, LLC (MBUSA) has entered into a settlement regarding claims relating to alleged mold and mildew type odors originating from the HVAC system in certain Mercedes-Benz vehicles. As part of the settlement, MBUSA has agreed to offer sliding-scale warranty coverage for certain vehicles diagnosed as having mold or mildew type odors originating from the HVAC system?although that coverage will not take effect until the settlement is judicially approved and other events occur; likely not until December 7, 2020 at the earliest (see below). If the settlement becomes effective, coverage will include cleaning of the evaporator and replacement of the HVAC filters

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
Complaint and recall counts across every year of this model
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. Older model years have had longer for reports to accumulate.
