Model-level reading
What changes the warranty calculation
Across 12 model years, the MINI Cooper records hold 229 complaints. A typical year in this file sits near 10 reports, although annual sales are not included.
The busiest year is 2015, carrying 73 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 EV traction battery replacement at $13,000. Remaining factory coverage gets first claim on that risk; an extra plan should not be paid twice for the same period.
