Summary Verdict

The 2008 Mini Cooper offers an enjoyable driving experience but requires attention to potential reliability concerns, particularly with its engines and transmissions. Common issues include oil leaks and timing chain problems on naturally aspirated engines, and turbocharger issues or carbon buildup on Cooper S models. Automatic transmissions can experience torque converter problems and fluid leaks. Suspension components like control arm bushings and rear shocks are also noted for wear. Electrical gremlins, such as window regulator failures, and exterior rust on lower body panels are also reported. While not overwhelmingly problematic, owners should be prepared for these potential repairs to maintain the vehicle’s performance and longevity.
