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 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. This was a $1500 repair cost. Mini cooper said that 2010 mini coopers were not covered. Only minis up to tne year 2009 were covered in that safety recall so I paid out of pocket. However, mini cooper used the same part that had been recalled on my 2010. It failed in 2017 and the replacement part has now failed again. Mini cooper called it a "known" issue, but would not cover the replacement cost in 2017. Repair order number with mini cooper dealer: 262724 and part number 13-51-7-588-879

High pressure fuel pump needs replaced @ 30,000 miles

Filed Aug 23, 2019 · Fuel system · CA

The high pressure fuel pump had the warranty extended to 10 years or 120000 miles due to federal emissions requirements on all years except the 2010. M01 01 16 [si] july 2016 shows the 2011 and 2012 and a letter from mini shows 2007 -2009. Nobody at mini corporate understands why the 2010 was left out, but all agree it is the same pump and I have found thousands of complaints online saying the dealer did not honor the warranty because it was the wrong the year. These pumps fail and the vehicle fails emissions testing. The pump is 1300 dollars plus labor and can only be done at the dealer.

High pressure fuel pump failed, mini has issued ext warranties o the 2009, 2001, 20012 models because of this issue but not this model. Car is below 100,000 miles if these years have problems and now I am having a problem should the 2010 models be covered

While moving in traffic and accelerating, the fuel pump cut out and the engine died, forcing the driver to maneuver in traffic (coasting) eventually coming to stop in a left hand turn lane which was then blocked with the dead vehicle. Though the vehicle was undamaged, the possibility of a collision existed. Research indicates that minis from 2010-early 2012 had similar problems, resulting in mini USA extending the warranty on the fuel pump to 10 years/ 120,000 miles. Vehicles produced on or after 3/1/2012 (including mine) were fitted with different equipment. No recall was conducted. My car had 25,000 miles on it when the fuel pump failed.
