Which Mercedes-Benz C204.9 years should you avoid?
On raw complaint volume the 2014 is the weakest year on record, with 8 complaints concentrated in the electrical system.
Read these numbers with sales volume in mind. A model year that sold in huge numbers naturally accumulates more reports than a rare one, and older cars have had more years to fail. The stronger signal is the severity columns and whether the same component keeps coming up year after year.
