What owners report

Owners of the 2006 MINI Cooper most often describe the passenger airbag warning light coming on because the front-passenger seat occupancy sensor mat has failed, which many say disables the passenger airbag. The second large group of complaints describes sudden loss of power steering assist, sometimes intermittent and returning after a restart, at widely varying mileages. Transmission and clutch problems, engine faults, and a burned heated seat are also reported, usually between roughly 45,000 and 90,000 miles.

  1. Air bags

    Passenger airbag light on (seat occupancy sensor)

    • 95 complaints (48%)
    • median 63,650 mi at 7.6 yrs old (84 state mileage)
    • 3 mention a crash, fire or injury
    • owner-quoted repair $1,200 (median of 30 quotes)
    • filed 2008–2023

    The red airbag warning light comes on, sometimes intermittently and later staying on, and the passenger airbag is shown as deactivated. Owners say a dealer or independent shop diagnosed the front passenger seat occupancy mat sensor as faulty and quoted repairs commonly around $1,000-$1,500, often replacing the seat or mat assembly. Several owners report being told the part was not covered once out of warranty, and some mention a sensor replaced earlier failing again. Complaints also describe the seat belt warning light or chime activating with no one in the seat. Widely spread, from under 15,000 miles to well over 100,000, with many reports between about 45,000 and 80,000 miles.

    Recall 15V2050002 related service bulletins

    What to check: Before buying, turn the ignition on and confirm the airbag light goes out and the passenger airbag status reads correctly with an adult in the seat. Ask whether campaign 15V205000 was performed and whether the seat mat sensor has been replaced, and when.

    2 excerpts from owner complaints in NHTSA records

    “I had to go ahead and have the air bag sensors in the passenger seat replaced last week, because I will have a passenger on a trip to utah soon. When I complained to one of the service people, that the passenger seat was rarely used, he started bloviating as to how heat can break down the materials in the sensors.”

    NHTSA complaint #10531526, filed 2013-07, 62,000 miles

    “Occupancy sensor mat bad and passenger air bag disabled light on. A known issue and bmw autos and suvs have been recalled for this issue. I believe the Mini passenger seat occupancy sensor mat is the same design as the bmw 3 series and should also be recalled. From what I understand, this disables the passenger airbag putting a passenger in danger. The bmw recall campaign is no. 13v-564.”

    NHTSA complaint #10609863, filed 2014-07, 65,000 miles
  2. Steering

    Sudden loss of power steering assist

    • 60 complaints (30%)
    • median 79,301 mi at 8.6 yrs old (52 state mileage)
    • 7 mention a crash, fire or injury
    • owner-quoted repair $1,245 (median of 7 quotes)
    • filed 2010–2025

    Owners describe the steering wheel suddenly becoming very heavy while driving or pulling out of a parking spot, with some saying assist returns after switching the car off and restarting, and others saying it never came back. Complaints mention a whining or scratching noise from the power steering pump, a check engine light appearing at the same time, and dealers diagnosing a failed power steering pump. A few reports describe smoke or fire in the engine compartment connected with the steering pump area, and one owner notes the pump drained the battery. Most reports fall between roughly 45,000 and 110,000 miles, across both cold-weather and warm-weather use.

    4 related service bulletins

    What to check: Ask whether the electro-hydraulic power steering pump and its cooling fan have been replaced or covered by any warranty extension, and listen for pump whine. During the test drive, check that assist is present at low speed and after a restart.

    2 excerpts from owner complaints in NHTSA records

    “The power steering on my 2006 Mini Cooper spontaneously combusted, melting the power steering harness and draining the battery. The incident went like this: when we returned from an extended vacation, the car wouldn't start because of a dead battery. We jumped started it using jumper cables. When I tried to drive away, there was no power steering. …”

    NHTSA complaint #10701645, filed 2015-03, 35,477 miles

    “Good morning, I have a 2006 Mini Cooper and the power steering unit failed. I was driving and the steering wheel became very heavy (power steering fluid was ok) the unit just gave out. I read that the NHTSA issued a recall for the power steering unit for 2002 to 2005 coopers recall 15v660000 (the 2002 thru 2006 are all first generation models). …”

    NHTSA complaint #11092178, filed 2018-05, 110,000 miles
  3. Transmission and drivetrain

    Automatic/CVT transmission slipping or failing

    • 16 complaints (8%)
    • median 71,000 mi at 7.3 yrs old (15 state mileage)
    • 1 mention a crash, fire or injury
    • filed 2011–2016

    Owners of automatic cars describe the transmission hesitating, slipping in and out of gear, holding revs without the car moving, refusing to shift into second gear, or making loud noises before stopping altogether. Some report the car lunging forward or backward when shifted into drive or reverse, and others describe being unable to select gears or getting stuck in fourth. Complaints say dealers diagnosed an internal transmission failure needing replacement, and that the manufacturer sometimes offered to cover part of the cost. Reported from as low as about 13,000 miles up to roughly 114,000, with many records between 45,000 and 90,000 miles.

    2 related service bulletins

    What to check: On a test drive, feel for hesitation or a flare in revs between 20 and 50 mph and listen for whine or clunking. Ask whether the transmission or CVT has been rebuilt or replaced and whether any parts warranty extension applies.

    2 excerpts from owner complaints in NHTSA records

    “Mini Cooper transmission fail. The car does not go between 20 to 50 MPH. It has no power and that can be dangers when I am getting into the highway and cars are going at a high speed. On top of it my car stalled in the middle of rush hour. Lucky I got it started and was able to make it home. Seems like everyone is having this problem the car need to be recall and get it faxed because someone can die.”

    NHTSA complaint #10472689, filed 2012-08, 114,000 miles

    “I was driving in moderate traffic (40mph) when my car suddenly jerked so hard it felt like someone hit me from behind. Prior to this incident, I was feeling the jerkiness slightly and intermittently (felt like downshifting). After reading people's complaints in Mini forums, I'm starting to think this could be the beginning of my transmission failure. Luckily no one was hurt but if this continues, there could be some major injuries involved. About four months ago, my Mini started to overheat. …”

    NHTSA complaint #10531796, filed 2013-07, 62,300 miles
  4. Engine

    Engine misfire, rough running and cooling/overheat faults

    • 14 complaints (7%)
    • median 76,500 mi at 7.5 yrs old (12 state mileage)
    • 2 mention a crash, fire or injury
    • filed 2011–2016

    Owners describe the engine losing power, idling roughly and running unevenly after a mechanic found deteriorated nylon caps on the hydraulic lash adjusters affecting compression. Other complaints describe a loud noise traced to a loose crank pulley or belt, overheating with smoke from the engine bay, and the service engine light or reduced-power message appearing. Mostly reported between about 31,000 and 92,000 miles.

    4 related service bulletins

    What to check: Check for rough idle, ticking from the top of the engine and any stored fault codes, and ask whether cooling fan operation and the crank pulley/belt have been inspected. Confirm whether any DME software updates were applied.

    2 excerpts from owner complaints in NHTSA records

    “Car lost power and started running and idling very rough. Service shop discovered that the nylon caps for the hydraulic lash valves had deteriorated and cracked and in some cases had fallen completely off having a negative affect on the engine compression. The original caps are bright yellow and after use and heat they turn orange/brown. Internet research shows some Mini's have steel lash caps. Seems that a engine component susceptible to heat damage should not be made of nylon/plastic. …”

    NHTSA complaint #10485395, filed 2012-11, 92,000 miles

    “The contact owns a 2006 Mini Cooper. The contact stated that while driving, a loud sound was coming from the engine. A local mechanic diagnosed that the crank pulley fan belt that controlled the air conditioning and heater was loose. The manufacturer denied any assistance with repairs to the failure. The vehicle was repaired. The failure and current mileage was 31,039.”

    NHTSA complaint #10421044, filed 2011-08, 31,039 miles

Buying note. Have any 2006 Cooper checked by a shop familiar with the model for airbag seat sensor faults, power steering pump operation and transmission behavior, since these account for most owner complaints and repairs can be costly.

Example complaints

Air bags: “I was a passenger in a Mini Cooper 2006, my friend was hit head on by a drunk driver on a city street. My friend's Mini Cooper 2006 was totaled.

NHTSA complaint #10970364, filed 2017-04, 57,988 miles

Steering: “Car had a burning smell then the power steering went complety off while driving . Mini has an extended warranty for Mini r53 first generation 2002-2005 but the 2006 is also a first generation and the problem was not fixed .called Mini and and was told they couldnt help me and I believe they should warranty the 2006 model before a fire starts or someone gets hurt or worse”

NHTSA complaint #10840187, filed 2016-03, 76,204 miles

Transmission and drivetrain: “The air conditioning had stopped blowing cool air. Then when I was parked, and idled, my power steering stopped working while trying to back out. After wrestling with the wheel for a minute to get out of a parking lot area, the power steering came back on. The mechanic said one of my coolant fans does not work. This may be part of a recall that affect 2005 minis with coolant fan/power steering, however my car was made just a few months past the recall.”

NHTSA complaint #11337932, filed 2020-07, 68,000 miles
