2005 Mini Cooper Convertible

No clear pattern

0% of complaints about the 2005 Mini Cooper Convertible arrived in its first year of service. That is an unusual figure for a 2005 vehicle, but with only 115 complaints on record the sample is too small to call it a pattern — the margin of error covers the range where ordinary vehicles sit. The figures below are reported without a verdict. The most-reported system is steering (79 complaints), typically at 6.9 yr or about 74,000 miles.

Complaints: 115
Median age at failure: 6.9 yr
Median mileage: 68,549 n=108
Crash / fire / tow: 9.6% of reports

Air bags:frontal

BMW of North America, LLC (BMW) is recalling certain model year 2005-2006 MINI Cooper and Cooper S vehicles manufactured January 5, 2005, to November 28, 2006, and 2005-2008 MINI Cooper Convertible and Cooper S Convertible vehicles manufactured January 5, 2005, to July 31, 2008. Due to manufacturing, installation, and exposure issues, the front passenger seat occupant detection mat may not function properly and, as a result, the front passenger air bag may not deploy in a crash.

An improperly functioning mat may cause the passenger frontal air bag to be inactive when the seat is occupied, and in the event of a crash, the air bag will not deploy, increasing the passenger's risk of injury.

Steering 45,000 mi 4.8 yr in service

I WAS DRIVING DOWN THE STREET AT ABOUT 40 MPH AND MY STEERING BECAME EXTREMELY HARD AND ALMOST REFUSED TO COMPLETELY WORK AS I WAS ROUNDING A BEND! I HAD TO SLAM ON MY BRAKES TO AVOID AN ACCIDENT AND SLOWLY INCH TO A SAFE PARKING SPOT. AFTER BEING SCARED OUT OF MY WITS, I CALMED DOWN AND PARKED MY CAR. I LET THE CAR SIT OVERNIGHT AND CHECKED POWER STEERING FLUID AND IT WAS FULL. I THEN LOOKED ONLINE AND FOUND MANY MINI OWNERS WITH THE SAME PROBLEM. MINI SAYS THEY WILL NOT FIX IT. *TR

Steering 45,000 mi 4.8 yr in service

REGULAR DRIVING AT AROUND 6PM AT ABOUT 40MPH AROUND A BEND, COMPLETE POWER STEERING FAILURE, THE CAR BECAME VERY HEAVY TO STEER, WITH NO PRIOR WARNING, AND NO WARNING LIGHTS. ALMOST CAUSED AN ACCIDENT AS THE CAR FAILED TO STEER. NOTHING HAS BEEN DONE, THE WARRANTY HAS BEEN OVER FOR 3 MONTHS AND MINI ARE SAYING A GOODWILL REPAIR MIGHT BE AVAILABLE, BUT WILL NOT DO A FREE DIAGNOSTIC, HELP US GET TO A DEALERSHIP OR PROMISE ANYTHING BEFOREHAND. A NEW POWER STEERING PUMP IS LIKELY NEEDED, AS PER THE EVIDENCE OF THE EUROPEAN RECALL, AND OTHER MINI DRIVER TESTIMONY. *TR

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
