Is an Extended Warranty Worth It for a 2018 Ford Focus?

Model-year reading

What the 2018 record can and cannot say

825 complaints sit in the 2018 record. The total is 135 below the median year in this model file, a useful internal reference that still cannot supply a defect rate.

Power Train appears most often among the shown tags, with 292 reports and a 35.4% share. One complaint may name several components, so the percentage is not a piece of a probability model.

A $13,000 midpoint makes EV traction battery replacement the largest parts scenario in the applicable list. Factory overlap and contract exclusions decide whether that amount belongs in warranty savings.

Evidence and provenance

Three evidence layers, kept separate

NHTSA signals: 825 submitted complaints, 7 recalls and 106 manufacturer communications. These are report counts, not failure probabilities.

EPA configuration evidence: 8 matched fuel-economy configurations help remove incompatible repair scenarios.

Repair-cost modelling: 36 applicable non-wear scenarios use published benchmarks where available plus parts and independent-shop labour assumptions. These ranges are not dealer quotes, repair-shop quotes or invoices.
