How we read this (methodology)

How to read this: raw complaint totals are not a clean reliability score — a model year with more cars sold, or simply more years on the road, accumulates more complaints regardless of how good it is. So this page leans on two signals that are not distorted by sales volume: the share of complaints falling on each vehicle system (the breakdown above) and NHTSA's own crash / fire / injury / death flags. When we compare model years of the same model, we normalise by years on the road (complaints ÷ vehicle age) rather than comparing raw totals. Age-normalised, the 2015 Buick Enclave draws about 14.2 complaints per year on the road, ranking 4 of 14 among the Buick Enclave model years we have ingested (1 = most complaints per year on road).

Before you buy this Buick Enclave

Don't buy on the strength of a problems page alone. Check the exact VIN of the car you're looking at. The open recalls are free, and the full $19 safety report pulls every complaint, safety rating and a downloadable PDF for that one vehicle.
