The C-Max has been assigned 4 TSBs over 2 model years.
TSBs contain recommended steps and procedures for diagnosing or repairing a known problem. They are issued directly by Ford to service technicians. You'll often see TSBs used as evidence in lawsuits when owners feel the automaker should help with repairs.
A TSB can cover multiple models and years. The 2011 and 2012 model years has been involved in the most campaigns with 3 total service bulletins.
