Model-year reading

What the 2018 record can and cannot say

840 complaints sit in the 2018 record. The total is 478 above the median year in this model file, a useful internal reference that still cannot supply a defect rate.

Electrical System appears most often among the shown tags, with 328 reports and a 39% share. One complaint may name several components, so the percentage is not a piece of a probability model.

A $7,000 midpoint makes Engine replacement or major internal repair the largest parts scenario in the applicable list. Factory overlap and contract exclusions decide whether that amount belongs in warranty savings.
