GarageCalc What the data says
Power train accounts for about 23% of this year's Buick Enclave complaints. Complaints are spread across several areas, which reads more like normal ownership noise than a single defect.
The 2020 model year contributes 19 complaints (22%). No single model year dominates, so this looks like a line-wide pattern rather than one bad year.
Complaints are up year over year, 77 to 86 (+12%), against a market that rose about 2%. Year-over-year movement is the most useful signal here: a model's sales are roughly stable from one year to the next, so a sharp rise means the per-vehicle complaint rate genuinely moved, not just that the model is popular.
How to read this
Raw complaint totals track how many Buick Enclaves are on the road as much as they track quality, so a high count on a best-seller is partly a volume story. Complaints are also self-reported: they capture what owners chose to file, not a controlled survey. Use these numbers to know where to look during a pre-purchase inspection and which recalls to check, not as a verdict on their own.
