What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2011 MINI Cooper S, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
Car stalls while driving and will not start again. No codes thrown. Found relay K96 on Junction Box Electronics module to have cracked through-hole solder joints resulting in bad continuity. Relay K96 supplies power to the low pressure fuel pump in the tank, thus with bad continuity, the pump gets no power. Relay K96 P/N is NEC Philippines P/N EP2F-B3G1ST. This issue has happened to many other people with the same car that I know. I suspect heat cycles over time stressed and fatigued the solder joints, causing the joint to crack. Overall the circuit board layout needs a heat sink for the relay to alleviate the heat produced from operation. I am IPC certified and work with aircraft engine electronics regularly and have seen similar issues.
The contact owns a 2011 Mini Cooper S. The contact received a recall notification for NHTSA Campaign Number: 18V248000 (Engine and Engine Cooling) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was notified of the issue. The contact had not experienced a failure. Parts distribution disconnect.
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
Failure of the Footwell Module failed due to corrosion by water intrusion as diagnosed by Mini Dealership. Windows, Turn signals and lights were inoperable as a result of failure. This matched the situation outlined in your recall notice Part 573 Safety Recall Report 23V-337. Car matched the model/years affected/listed in recall. However, Mini Dealer informed me my VIN was not listed in their recall. Subsequent research indicated that NHTSA/Mini limited the recall to cars purchased cars sold or registered in specific states (not part of the Safety recall report). Ref NEF-107DM dated 5/19/2023. I drove car in those states but did not buy or register the vehicle in them. I encourage you to have Mini extend it's recall/warranty to all vehicles which exhibit the safety failure.

From owner reports, verbatim
PREMATURE HIGH PRESSURE FUEL PUMP FAILURE MAY LEAD TO LOSS IN POWER, FURTHERING THE POTENTIAL FOR A WRECK. ENGINE ENTERS "LIMP HOME" MODE, WHICH REDUCES POWER CONSIDERABLY AND MAKES ACCELERATION MUCH SLOWER THAN NORMAL. CHECK ENGINE LIGHT COMES ON, SEVERAL OBD-II DIAGNOSTICS CODES APPEAR. *TR
AS I WAS ACCELERATING WHILE MERGING ONTO A HIGHWAY, AT APPROXIMATELY 55-60 MPH, IT FELT AS IF THE CAR LOST ALL POWER FROM THE DRIVE TRAIN. THE POWER REENGAGED ABOUT A SECOND LATER, AND OVER THE NEXT 5-10 SECONDS THE CAR LOST POWER/REENGAGED TWO MORE TIMES. NO WARNING LIGHTS WERE TRIGGERED ON THE DASH. I'VE TAKEN THE CAR INTO DEALERSHIP AND REFERENCED SERVICE BULLETIN NUMBER SIM12-02-11/NHTSA ITEM NUMBER 10040855. DEALER REPORTS THAT BECAUSE IT CANNOT REPLICATE THE ISSUE AND THERE ARE NO REPORTED FAULT CODES, IT APPEARS THAT THERE IS NOTHING WRONG WITH MY CAR, THEREFORE IT CANNOT CONFIRM IF I'M ON MOST RECENT SOFTWARE OR PERFORM SOFTWARE UPDATE TO FIX ERROR REFERENCED IN THE SERVICE BULLETIN. *TR

AFTER COMING HOME FROM A ROUTINE DRIVE. I PARKED MY CAR IN THE DRIVE WAY. ABOUT 30 MINUTES LATER I SMELT SOMETHING BURNING AND NOTICED MY HOOD OF MY CAR SMOKING. I IMMEDIATELY RAN OUTSIDE AND STARTED HOUSING OF THE BUBBLING HOOD WITH A GARDEN HOSE. I MANAGED TO POP THE HOOD AND PUT OUT THE FIRE WHICH HAD COVER MOST OF THE ENGINE AT THAT TIME.
