2010 MINI Cooper S Problems

What owners report

Owners of this model year report engine problems most often, and the timing chain system stands out as the recurring theme: rattles, oil leaks and sudden loss of power are described across a wide mileage range. A second cluster involves the high-pressure fuel pump stalling or refusing to restart, and several complaints describe smoke, oil leaks or fire in the engine bay.

   Engine

   Timing chain rattle, stretch or breakage

   Mentioned in 26 of 53 sampled complaints

   Complaints describe a rattle or ticking from the engine, often most noticeable at cold start, that worsens over time and can be followed by an oil leak, a check engine light, or a sudden loss of power while driving. In the more severe reports the chain or its tensioner fails and the engine stops running or is damaged and needs replacement. Owners say dealers diagnosed the timing chain and quoted repairs, and several mention that a class action settlement covered some vehicles but not theirs. Reported from roughly 25,000 to 110,000 miles, with many descriptions in the 40,000-70,000 mile range and several noting the noise is worse in cold weather.

   What to check: Ask whether the timing chain, tensioner and guides have been replaced, and request receipts. Listen for a cold-start rattle at idle and around 2,000-3,000 rpm on a test drive.

   2 excerpts from owner complaints in NHTSA records

   “Purchased car w/50,000 miles on it and have already had water pump replaced and now while driving down the road going about 40 MPH the timing belt broke and blew parts into the engine, so it pretty much needs a new engine already now 25,000 miles after we bought it. Lots of complaints about the timing belt/chain on these 2010 models. Seems odd to me.”

   NHTSA complaint #10816892, filed 2015-12, 80,000 miles

   “I was driving my 2010 Mini Cooper S 50-55 MPH when I heard a loud noise come from the engine compartment. From then on, the engine was making a rattling and clacking noise and the oil light eventually came on. Pulled over to the side of the road and got out to look at the car. Oil was all over the frontside and wheelwell of the car. All the oil had came out of the engine. …”

   • median 66,568 mi at 6.1 yrs old (5 state mileage, few)
   • 4 mention a crash, fire or injury
   • filed 2011–2017

   Complaints describe smoke and a burning oil smell from under the hood, overheating at speed, and in some cases a fire in the engine bay while parked or driving. Owners report oil leaking from the turbo oil feed line or from around the engine, and mechanics diagnosing a failed auxiliary water pump or turbocharger oil supply. Several mention the car was towed and the engine needed replacement. Spread from about 26,000 to 132,000 miles, with several reports in the 60,000-90,000 mile range.

   What to check: Check under the hood and under the car for oil residue, especially around the turbo lines and the auxiliary water pump, and ask whether the auxiliary water pump recall work was completed.

   “The vehicle in question was being towed behind my motor home (which I do all the time) when another driver got my attention to see smoke coming from my car. I immediately pulled over grabbed my fire extinguishers and lifted the hood and put out the fire, before the fire department arrived. 6 firemen were unable to determine the cause or where it started.”

   NHTSA complaint #10432258, filed 2011-10

   “The turbo oil feed line is leaking. It is a know issue with these vehicles, it can result in a fire as the oil sprays our the lines on the exhaust. Dealer has to comment about the repairs being free of charge but does say it's a known issue. Many Mini coopers have caught on fire because of this issue”

   Fuel system

   High-pressure fuel pump failure and stalling

   • 6 complaints (10%)
   • median 84,400 mi at 10.0 yrs old (4 state mileage, few)
   • filed 2018–2020

   Owners describe the engine cutting out or failing to start, stalling at low speed, and running roughly until the accelerator is held above a few thousand rpm. Several say the car died on the highway and had to be coasted to the shoulder, and that a dealer replaced the high-pressure fuel pump. Complaints note that an extended warranty on this pump was offered for other model years but that this year was told it was not covered. Mostly reported between roughly 70,000 and 100,000 miles, with some failures described at lower mileage.

   What to check: Ask if the high-pressure fuel pump has been replaced and keep the receipt; a long crank or rough idle after a cold start is worth investigating before purchase.

   “The car completely quits running while you are driving it. Check engine light comes on but car has already died. Have to coast to a stop with no power steering since the engine has died. Car will not always restart. Sometimes it will crank but not turn over. Sometimes it will restart. Today it died while I was going 65mph on the interstate a d I had to dodge across 3 lanes of traffic to get to the shoulder. Have had this exact issue before. 3 yrs ago I replaced the high pressure fuel pump for this exact same problem. …”

   NHTSA complaint #11373045, filed 2020-11, 100,000 miles

   “Just had to have a high pressure fuel pump replaced in my Mini Cooper S convertible and had . I understand that all the fuel pumps in this year make of car were recalled except the one on the convertible?? Please let me know why the fuel pump is any different? It actually went out on an interstate and I had to pull over and was almost struck by a semi truck. I have the bill for the repair which cost me over $1400.00..”

   Air bags

   Passenger airbag off warning / seat sensor fault

   • 5 complaints (8%)
   • median 82,000 mi at 6.8 yrs old (5 state mileage, few)
   • filed 2010–2020

   Complaints describe the passenger airbag indicator showing the airbag as off even with someone in the seat, sometimes intermittently and sometimes continuously. One report describes the seat occupancy mat overheating and melting its circuit while the car was parked. Owners say dealers either could not reproduce the fault or quoted a repair in the region of a thousand dollars or more. Reported from very low mileage up to about 120,000 miles, with no clear pattern by age.

   What to check: With the ignition on and a passenger seated, confirm the passenger airbag indicator reads on; if the light stays off or flickers, have the seat occupancy sensor checked.

   “The passenger airbag off light comes on with a passenger in the car. The light comes on and remains on at random intervals. I brought the car to the only Mini dealer in colorado and they told me that they couldn't duplicate the fault and that there wasn't a fault code in the computer. I asked to speak to the service manager and he told me that this was normal and that my 130 lb. Wife didn't weigh enough to warrant the srs system in the car.”

   NHTSA complaint #10363443, filed 2010-11, 5,900 miles

   “The passenger side air bag light indicated the air bag was not engaged. The passenger seat started getting very hot (this model does not have heated seats). We removed the seat from the vehicle and innvestigated. We found that the air bag seat mat was overheating. The circuit was melted from the heat. If we had not removed the seat from the car it would have caught fire. The vehicle was parked in the garage at the time. However, the car was driven earlier in the day and the light was on then to indicate the passenger air bag was not on. …”

Buying note. A pre-purchase inspection by a shop familiar with this engine is worthwhile, focusing on timing chain noise, oil leaks and the fuel pump. Ask for service records showing whether the timing chain and high-pressure fuel pump have already been addressed.
