What owners report
Owners of this model year describe two dominant problems: repeated loss of power-assisted steering, often intermittent and sometimes accompanied by smoke or burning from the steering pump area, and transmission failures, most associated with the CVT automatic. Both tend to appear well under 100,000 miles in the complaints, and owners often report that the steering problem can recur even after a recall repair was performed.

Power steering assist cuts out intermittently or fails
- 141 complaints (44%)
- median 80,000 mi at 8.6 yrs old (134 state mileage)
- 20 mention a crash, fire or injury
- owner-quoted repair $1,180 (median of 23 quotes)
- filed 2005–2025
Owners describe the steering suddenly becoming very heavy and hard to turn, sometimes at speed or in a turn, with no warning light beforehand. In many complaints the assist returns after the car is shut off and restarted, then drops out again; others report it never came back. Dealers commonly diagnosed a failed power steering pump, and some owners were told the pump and its cooling fan needed replacing, with one owner reporting the wiring harness at the pump was corroded and shorted. Mostly reported between roughly 50,000 and 130,000 miles, with a number of cases in the 60,000-85,000 mile range; several owners describe it starting intermittently over weeks or months.
Recall 15V6600008 related service bulletins
What to check: Ask whether recall 15V660000 was completed and whether the pump, cooling fan, and pump wiring were replaced or re-checked afterward, since owners report the assist can drop out again later. On a test drive, note any heaviness at low speed or in a parking-lot turn, and listen for a cooling fan running at the pump after the car is switched off.

“After car was sitting for 4 hours the power steering did not work; I muscled the car home and when I started it to take to my mechanic the next day it was working again; I reviewed this on line and discovered that it has happened to others (Mini Cooper, 56,000 miles, '03.”
NHTSA complaint #10418144, filed 2011-08, 57,000 miles“Hi there is a problem with my Mini Cooper losing power steering , I have lost the power steering few times this week and when I took it to the bmw near my area they told me its a known problem with Mini cars from 2001 to 2005 as the psp ( power steering pump ) on the models have a fault and you may lose the steering power at any time . I almost had 2 accidents because of this week and they are asking my to pay 550 for a new pump . …”
NHTSA complaint #10370909, filed 2010-12, 63,950 miles - Transmission and drivetrain
CVT automatic transmission slips, noise, or fails
- 77 complaints (24%)
- median 69,000 mi at 6.6 yrs old (73 state mileage)
- owner-quoted repair $7,800 (median of 37 quotes)
- filed 2003–2017
Owners of cars with the CVT automatic describe the engine revving without the car accelerating, slipping at all speeds, jerking at low speed, unusual noises, and in some cases total loss of drive while on the road. Dealers and shops commonly quoted a full transmission replacement, and some owners were told parts for the CVT were not sold separately. A few owners describe the transmission being replaced more than once. Reported from about 37,000 to 86,000 miles, with many cases in the 60,000-80,000 mile range.
What to check: Confirm which transmission the car has, since the automatic complaints center on the CVT, and ask for service records of any transmission repair or replacement. During a test drive, listen for noise and watch for revving without acceleration or jerking at low speed.

“Driving to work one morning and the engine response seemed sluggish. Called a mechanic friend, he said it's either the spark plugs or transmission problem. Book appointment for service. Several days later, complete transmission failure at 83,000km. Mini Cooper has said that I need a completely new transmission, being just off warranty by 3,000km I was quoted approximately $9,000 for repairs.”
NHTSA complaint #10224836, filed 2008-04, 52,000 miles“I own a 2003 Mini Cooper with a CVT automatic transmission. The car has 80000 miles on it and the CVT failed completely. There is no alternative but to get a new replacement with an updated 2005 model which I have been quoted from 2 places $8000 for parts and labor. This is my complaint. If they know there is a problem with the CVT why have they not contacted me? Please contact if you need further details.”

- owner-quoted repair $1,600 (median of 9 quotes)
- filed 2006–2016
Several owners describe smoke or flames from the engine bay traced to the power steering pump and its cooling fan, often after the car had been parked. Others say the pump or fan kept running after the ignition was off, in one case draining the battery, and in another the owner disconnected the battery to stop it. Repairs reported include the pump, the fan, the wiring harness, and nearby hoses. Reported across a wide mileage range, from roughly 33,000 to 165,000 miles, and often while the vehicle was parked and unattended.
Recall 15V6600006 related service bulletins
What to check: Ask whether the steering pump cooling fan and wiring were inspected or replaced, and check for melted or chafed wiring near the pump. Owners mention the fan sometimes runs with the key off, so it is worth verifying the fan stops after the car is shut down.

“My car was parked after being driven for 20 miles or so. Within ten minutes of being parked, my officemate ran into the office saying my car was smoking. It was actually on fire. The fire department came and put out the fire. My mechanic says that it is a failure of the power steering pump. I need to replace it, the fan, and most of the wiring around the part. Right now, I'm trying to find a wire for him that Mini will not get him. It is in the process of being corrected.”
NHTSA complaint #10228713, filed 2008-05, 56,000 miles“At approximately 35mph the power steering of my 2003 Mini Cooper erratically engaged and disengaged several times. I responded by slowing down and trying to maintain control of the vehicle. Once stopped, I turned the car off completely. Once out of the vehicle I heard an electric motor running. I opened the hood to investigate and noted a small amount of smoke rising from the aft portion of the engine compartment. I went back to the ignition switch to confirm it was off and removed the keys. …”

Some owners report smoke or fire in the engine compartment traced to electrical parts, including a melted connection between the wiring harness and the power steering pump, and a failed auxiliary cooling fan. In one complaint the car was parked and locked when smoke appeared; in another, smoke started right after a new battery was connected. Repairs reported include the pump, the fan, wiring, and related parts. Reported from roughly 33,000 to 84,000 miles, typically with the car parked or just after start-up.
Recall 15V6600003 related service bulletins

NHTSA complaint #10454920, filed 2012-04, 83,567 miles - Electrical system
Heated seat overheating and air bag warning light
- 22 complaints (7%)
- median 75,250 mi at 9.3 yrs old (20 state mileage)
- 5 mention a crash, fire or injury
- filed 2004–2022
A few owners report electrical faults inside the cabin: a heated driver's seat that became extremely hot and burned a hole in the seat cover with smoldering smoke, and an air bag warning light that led to a faulty air bag module being replaced. Battery failures without warning are also mentioned in one complaint. Reported from very low mileage up to about 121,000 miles, with the heated-seat case at higher mileage.
What to check: Test the heated seats and watch for uneven or excessive heat, and confirm the air bag warning light goes out after start-up. Ask whether the battery has been replaced and when.

“Upon turning on my driver's side heated seat, one part of my back seemed to be getting extremely hot. Upon turning around, I saw a small hole had been burned in the seat cover and was smoldering and smoking. I immediately turned off the seat warmer. It took many minutes to cool down and stop smoking. Thankfully the vehicle was stationary when this happened. If it had been in motion, my safety would certainly have been comprised, as I could have sustained burns before pulling the car to the side of the road. …”
NHTSA complaint #10436074, filed 2011-11, 121,000 miles“Battery failure. Battery has failed for the third time since car brand new in feb, 2003. On each occasion the vehicle would not start after having given no warning. The first failure was in 2005 at 26,000 mi., the second in 2007 at 51,000 mi., the third in 2008 at 68,000 mi. Each failed battery was a manufacturer's brand (Mini).”
NHTSA complaint #10250256, filed 2008-12, 68,500 miles
Buying note. These complaints concentrate on the power steering system and the CVT automatic, so a pre-purchase inspection focused on the steering pump, its fan and wiring, and the transmission is worth the cost. Ask for proof that recall 15V660000 was completed and request transmission service history, since owners report both problems recurring after repair.

Example complaints
Steering: “I was driving my car home from work on friday night, 2/22, when the steering wheel locked up on me and I had a hard time turning it. It then started working fine again after a few minutes. Then it locked up again while I was driving. Since it was on a highway I was doing over 60 m.p.h. It was terrifying not having complete control of my vehicle at that speed.”
NHTSA complaint #10500564, filed 2013-02, 136,000 milesTransmission and drivetrain: “The car would not easily shift gears. When I brought it to the Mini Cooper dealership, I was told that all of the transmission fluid leaked out of the transmission. The transmission is sealed , so the transmission fluid cannot be checked or changed. I was told that I needed to replace the transmission and clutch. The car should not have a sealed transmission if it can develop a leak so easily.”
NHTSA complaint #10817225, filed 2015-12, 113,300 milesElectrical system: “Drain hose from sunroof drain running down a-pillar came dislodged through normal wear and tear causing massive flooding to the interior of my car. It was rendered unserviceable and totaled, on june 16, 2014, but uncovered by insurance. This was nothing that I was aware of that was an issue, nor were any recalls ever issued on this issue. …”
NHTSA complaint #10622422, filed 2014-08, 68,000 milesVisibility (wipers, defrost, mirrors): “Both passenger and drivers side windows are stuttering when I try to roll them up or down. This is when I am even able to get them to work. Found that when the weather is hot, they won't work at all!! Meaning I am having to wait for it to cool down to roll the windows down if I am lucky and have on one occasion got stuck in my vehicle because the car door handle also would open the door from the inside and I couldn't open the window to open the door, which was very dangerous since I had a child with me. …”
