“My 2009 Mini Cooper S made rattle noise and the whole timing chain got replaced plus the thermostat house and water pump! The engine light still keeps on after trouble-shooting by my mechanics, which might be the computer issue which has to be figured out soon! The timing chain issue should be under fully-covered by manufacturer since too many Mini cooper owner have the same problem and paid thousand of dollars to fix it! My Mini is only about 55k miles and already has timing chain issue!”

“Mini released a service bulletin (campaign: sim 11 02 12) regarding faulty timing chain tensioner. At appx. 40k miles, my Cooper S was taken in for service and it was reported there was a rattle in the front of the engine. The dealership replaced the tensioner under warranty. Now the same issue has occurred. I am being told the entire timing chain assembly needs replacement at an approximate cost of $3k. Mini has offered to pay 1/2 the cost. …”

“I was driving down the highway and my car gave me a warning that my engine temp was way to high. I was lucky enough to have a good place to stop and check out whay was gong on. I open the hood, the engine is smoking and the coolant reservoir is neat empty. I look and see a pool of antifreeze coming from the thermostat. This is the third thermostat I have installed on this car and the second faulty one I have had in 3 months. This is also the second time I have had to stop on the highway due to a badly leaking thermostat.”

“Total loss of power as I was crossing a major highway, car towed to local bmw certified mechanic, shows timing chain misfire, needs total replacement with multiple components needing replaced due to timing chain problem. 3300$ worth of damage to engine. Apparent problem with timing chain on thousands of Mini cooper and they have not called a recall on the piece.
