Complaints across nearby Buick Riviera model years
Totals for the same nameplate, scaled against its highest year here. They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports. This shows where the reporting sits, not which year is better.
