What owners report

Owners of this model year report power steering trouble more than anything else: the power assist cuts in and out or fails outright, often with no warning, and some describe the pump running after the car is shut off and draining the battery. A second recurring theme is the passenger seat occupant-detection mat, which makes the airbag warning light come on and turns the front passenger airbag off; complaints also mention occasional transmission, electrical and heated-seat faults at higher mileages.

  1. Steering

    Power steering assist cuts out or fails

    • 205 complaints (65%)
    • median 70,000 mi at 6.7 yrs old (198 state mileage)
    • 13 mention a crash, fire or injury
    • owner-quoted repair $1,100 (median of 20 quotes)
    • filed 2008–2025

    Owners describe the power steering becoming suddenly very heavy, sometimes while turning at low speed and sometimes at highway speed, and often returning after the car is shut off and restarted. Many say the dealer diagnosed the electro-hydraulic power steering pump and quoted a replacement, and some owners note the pump kept running after the engine was off and drained the battery. Several mention whining or seepage from the pump before it failed. Complaints describe these episodes happening without a prior warning light. Mostly reported between roughly 40,000 and 100,000 miles, with some at much higher mileage; a few owners link the cutouts to hot weather or long highway drives.

    Recall 15V6600007 related service bulletins

    What to check: Ask whether the steering pump has been replaced or covered under the extended warranty or recall, and confirm the VIN is included in campaign 15V660000. During a test drive, turn the wheel at low speed and listen for whining or a fan running after shutdown.

    2 excerpts from owner complaints in NHTSA records

    “The passenger air bag weight sensor stop working. As a result my vehicle displays a warning that the passenger side air bags are off. My driver side fog light housing melted and crack apart. I used stock 55w halogen bulbs. My passenger side fog light housing has also begun to melt. My power steering is not leaking now. But it has been replaced 3 times.”

    NHTSA complaint #10474200, filed 2012-09, 75,000 miles

    “2005 Mini Cooper S power steering failed while turning off highway almost causing me to crash into an adjacent car because I had to muscle the car into a corner. This is a very serious problem which happened one more time later in the week while I was turning into my driveway. A woman might not be able to muscle the car correctly thus causing an accident.”

    NHTSA complaint #10408573, filed 2011-06, 61,509 miles
  2. Air bags

    Passenger airbag off / airbag warning light

    • 65 complaints (21%)
    • median 55,000 mi at 6.7 yrs old (59 state mileage)
    • 1 mention a crash, fire or injury
    • owner-quoted repair $1,300 (median of 15 quotes)
    • filed 2008–2019

    Owners report the passenger airbag indicator showing the airbag is off even with an adult in the seat, or the red airbag warning light staying on. Complaints attribute this to the occupant detection mat in the passenger seat and mention dealers quoting a costly seat cushion or sensor mat replacement, with some owners saying repairs did not fully resolve it. A few describe the light appearing after moving or adjusting the seats, and one owner says wiring connectors under the seats came loose. Reported from low mileage up to about 120,000 miles, and several owners note it first appeared during cold weather.

    Recall 15V2050002 related service bulletins

    What to check: With the key on, check that the passenger airbag indicator reads correctly with and without someone in the seat, and ask whether the occupant detection mat or campaign 15V205000 work has been done.

    2 excerpts from owner complaints in NHTSA records

    “When adjusting the driver and passenger seats, the airbag light illuminated. After researching online, I conducted troubleshooting. I verified that the wiring harnesses and connectors for the airbag sensors under both seats had come loose, and certain wires de-pinned. The car was running, and parked when this occurred.”

    NHTSA complaint #11186059, filed 2019-03, 62,527 miles

    “The airbag light for the passenger seat comes on intermittently when someone is sitting in the seat. Also, the light which indicates the passenger side airbag is off comes on when someone is sitting in the passenger seat. Certainly, this is a safety issue and we believe bmw/Mini should fix this at no charge.”

    NHTSA complaint #10403868, filed 2011-05, 47,500 miles
  3. Electrical system

    Electrical gremlins and battery drain

    • 71 complaints (23%)
    • median 68,000 mi at 6.5 yrs old (67 state mileage)
    • 11 mention a crash, fire or injury
    • owner-quoted repair $1,200 (median of 11 quotes)
    • filed 2008–2020

    Owners describe intermittent electrical faults such as windows that will not roll up, the radio cutting out, doors that unlock and relock but will not open, and dashboard lights going out. Some connect a dead battery with the power steering pump or fan staying on after the car is off, and others report the battery light flashing along with steering cutouts. Spread from about 40,000 to over 170,000 miles, often described as intermittent and hard for dealers to reproduce.

    1 related service bulletin

    What to check: Check that windows, locks, the radio and interior lights all work, ask about battery age and any prior electrical repairs, and note whether the battery holds a charge after sitting.

    2 excerpts from owner complaints in NHTSA records

    “Upon starting the vehicle and sometimes while moving at low speeds the power steering would fail making the vehicle extremely difficult to steer. The dealer explained that the relay in the auxiliary engine fan had failed likely as a result of the power steering fan failing. Both the auxiliary engine fan and the power steering fan had to be replaced. The cost of the repairs and labor was $1060.14.”

    NHTSA complaint #10414129, filed 2011-07, 65,000 miles

    “Defect initially occurred at night time in rush hour traffic: dash-lights went out, turn indicator not functional, heater blower stopped working (causing fogging of windshield/windows), air bag lights went on, seat belt light on consequently had to pull on the side of road (limited visibility, no speed indicator, could not operate vehicle safely). A couple of attempts at ignition cycling partially restored functionality. …”

    NHTSA complaint #10319435, filed 2010-03, 40,800 miles
  4. Seats

    Heated seat overheating and burning

    Mentioned in 4 of 60 sampled complaints

    A small number of owners describe the seat heater burning a hole in the seat upholstery or clothing, or smoke coming from the seat area, in some cases with the heater not switched on. One owner reports the dealer found the occurrence unusual and charged for the repair. Complaints also note electrical faults in the seat area. Reported at low to moderate mileage, from about 18,000 to 135,000 miles.

    What to check: Test the seat heaters briefly on both seats and look for discoloration, burns or a burning smell in the seat cushion; ask whether any seat heater repairs have been done.

    An excerpt from owner complaints in NHTSA records

    “Driving to work in the am. I smell something in the car. When I look at my passenger side seat I saw smoke. Pull over and got a better look at it. I have a holes in my car seat and the two vest that I place on the seat. It appears the heated seat had a electrical failure. Took car to Mini dealer. They said it real odd this happen. They also nice to say I would have to paid to fix it. Look at many site on internet and seen bmw/Mini and other company have issues with heated seats. It do not seem to odd to me. …”

    NHTSA complaint #10492994, filed 2013-01, 135,000 miles

Buying note. A pre-purchase inspection focused on the power steering pump and the passenger seat occupant sensor is worthwhile on this model year, along with confirmation of whether the steering and airbag campaigns were completed for the VIN. Service records showing steering pump, seat heater and transmission work help gauge how much of this has already been addressed.

Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample. The excerpts come from NHTSA's public complaint records and are unverified; capitalisation is normalised, NHTSA staff notes are removed, and shortened text ends with “…”. Something wrong?

Example complaints

Steering: “Complete power steering failure on my way to work this morning while turning a corner from the highway to city street. I found an open safety recall dec 2015 for 2005 model Mini Cooper S but my 2005 VIN is not included. It seems a major safety concern like this would be taken care of by the oem.”

NHTSA complaint #10876831, filed 2016-06, 180,000 miles

Air bags: “My air bag light on the passenger side is on. Mini dealer says it is a broken sensor in the seat. I checked online forums and this is a common problem lots of complaints. Mini will not correct the problem unless I pay. It seems as if this is a safety issue and not an isolated case. I would think because of the nature of the problem there should be a recall.”

NHTSA complaint #10512832, filed 2013-05, 68,563 miles

Electrical system: “I got home from work parked car and heard a whining noise under hood I could see smoke and buring smell coming from steering cooling fan the fan stayed on and went into extreme high speed and continued to smoke and wiring burning ,I was fortunate enough to be able to disconnect battery which stopped fan and electrical burning I have car parked in drive way and contacted my insurance to file a claim ,I am afraid to start car and need to have car repaired”

NHTSA complaint #11053788, filed 2017-12, 100,000 miles

Transmission and drivetrain: “Transmission previously replaced at 48k miles by manufacturer due to noise. My transmission is broken. My tires chirp every time I push on the gas because the transmission does not know what gear to be in due to the bad body control valve. The transmission needs to be replaced because I cannot verify how much mechanical damage has taken place during the time that the valve body has been broken. Once the valve body breaks down, the mechanical unit also begins to break down. …”
