Model-year reading

What the 2018 record can and cannot say

The 2018 record contains 32 submitted complaints, 3 above the median year in this model file. Report volume is not a failure probability because vehicle age and sales exposure differ.

Engine leads the displayed component tags with 12 reports, accounting for 37.5% of this year's submitted complaints. Use that signal to inspect coverage wording, not to predict the next repair.

Engine replacement or major internal repair has a midpoint parts estimate of $7,000, before local labor. A service contract only changes that exposure when the part and cause of failure both qualify.
