Which Peterbilt 579 years should you avoid?
On raw complaint volume the 2022 is the weakest year on record, with 7 complaints concentrated in the power train. It carries 15 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.
