AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.

About this data
NHTSA complaints and recalls through October 2026. Complaints are counted once each, however many components they name. Original complaints are on NHTSA's page for the 1999 Buick Century.
Problem groups are formed by AI and may be approximate. BrakeNews flags unusual complaint patterns; they are not official defect findings. Investigation reports are written and checked by AI, with no human review. Owner reports do not establish that a defect exists.
