Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2006 Mini COOPER S - Convertible lead in one area — the air bags, 8 of 36 reports (22%), well ahead of the next concern. That matters, because the air bags are also the target of recall 15V-205 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 0 of the reports describe a crash and 2 a fire — a small share of the total, but worth weighing against the air bags 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.
All 36 complaints on record, top 8 components.
