All the midsize suvs we cover

Method and limits

Complaints: NHTSA public complaint database, model years 2015–2020, each decoded to its exact engine through the partial VIN it carries.
Do not compare complaint totals between engines or models — totals track sales. Only within-group shares (component mix, severity rates) are comparable, because volume cancels out.
Claims on this page only appear when they clear preset thresholds (deviation ≥1.25×, samples ≥500 mentions or ≥80 complaints). Absence of a claim means the data didn't support one, not that we didn't look.
