Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2007 Mini COOPER - Convertible lead in one area — the engine, 99 of 381 reports (26%), well ahead of the next concern. None of this vehicle's 1 recall campaigns target the engine, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 5 of the reports describe a crash and 23 a fire — a small share of the total, but worth weighing against the engine pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
