Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2004 Mini COOPER - ONE Hardtop dominate in one area — the steering, 412 of 529 reports (78%), well ahead of the next concern. That matters, because the steering are also the target of recall 15V-660 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 12 of the reports describe a crash and 14 a fire — a small share of the total, but worth weighing against the steering 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.
