Model-level reading
What changes the warranty calculation
Across 6 model years, the Buick Regal records hold 150 complaints. A typical year in this file sits near 27 reports, although annual sales are not included.
The busiest year is 2016, carrying 41 reports. More reports do not automatically mean worse reliability when older vehicles and larger sales pools have had more chances to appear.
The largest midpoint parts exposure in the applicable list is Engine replacement or major internal repair at $7,000. Remaining factory coverage gets first claim on that risk; an extra plan should not be paid twice for the same period.
