One problem related to loud engine noise has been reported for the 2009 Mini Cooper Clubman. The most recently reported issues are listed below.
After hearing a rattling while idling at a stop sign and then driving down the road, there was a terrible noise that came from the engine and the car lost all power. My husband pushed the car to the side of the road and opened the hood. It appeared that the timing chain had busted out of the top of the engine cover. We were very concerned as this could have happened on the highway, which he had just exited. We have been doing research and have found several others that have had this same issue in the Mini and would like to see it come to a resolution, as our mechanic is advising us that the cost of repair will be upwards for $6,000 and Mini is not covering cost of repair. We are wondering if there is a recall on these vehicles. We have read that their is an active class action suite, as well.
