One problem related to engine rattling and whining sounds has been reported for the 2010 Mini Cooper. The most recently reported issues are listed below.
Mini Cooper timing chain tensoner defect. I have a r56 hardtop 2010 Mini Cooper. My car started having issues like turning off while driving. A rattling noise under the hood, especially on the passenger side of the car. While I was driving I heard a loud snap noise and my car shut off. The engine would not turn over after that and when I looked under the hook there was a broken valve cover. The timing chain broke and caused massive amount of damage to my car. The Mini dealership in las vegas is not honoring the lawsuit. Not really sure how to proceed. They want $3,500. In repairs. My car is only at 83,000miles and just paid off. Not sure how to proceed.
