Which Mercedes-Benz S 450 years should you avoid?

On raw complaint volume the 2018 is the weakest year on record, with 7 complaints concentrated in the forward collision avoidance › automatic emergency braking. It carries 8 recalls.

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.
