“I purchased a brand new Mini Cooper S in 2009 w/ standard 3 years of factory maintenance and I later added on an extended warranty a few years later. 2014 I entered into a 3 year lease on a bmw. Aside from maintenance, the Mini was mostly garaged except for maintenance until th after a month of driving it, I heard a ticking sound that made me think it needed oil added, despite having one about 2 months prior. I added the Mini synthetic oil to the car and the ticking sound stopped for a week or two. Then it started rattling and shaking severely when driving low speeds or at an idle. …”
NHTSA complaint #10990672, filed 2017-05, 73,000 miles“While driving a 2009 Mini Cooper S at over 35 miles per hour the engine lost power and would not restart. Mechanic diagnosed it as a high pressure fuel injector failure and Mini refused to act in good faith and replace the product despite issuing an extended warranty on that specific component in a safety bulletin.”
NHTSA complaint #11162452, filed 2018-12, 147,000 miles“While idling at a red light, vehicle rpms varied dramatically and the engine shut off. Vehicle was able to be restarted and moved with the check engine light illuminated. Upon further investigation the valve cover was found to have a vacuum leak, which has become a common issue with Mini Cooper S models.”
NHTSA complaint #10617810, filed 2014-07, 44,000 miles“Fire did not occur, but there is a risk. Many Mini cooper models with turbochargers are experiencing a leaky oil feed line to the turbo after approximately 25,000 miles. Due to a poorly insulated rubber gasket. It is a manufacturing flaw, but Mini has failed to acknowledge the issue. This is a fire risk. The oil is allowed to leak into the engine bay, and it can destroy the engine because Mini coopers do not have an oil sensor.”
NHTSA complaint #10555546, filed 2013-12, 33,000 miles“The contact owns a 2009 Mini Cooper S. The contact stated that the check engine light would illuminate on the instrument panel and the vehicle would make a loud noise. The dealer diagnosed that fuel line was clogged, which made it difficult for the fuel to flow freely. The manufacturer was not notified. The vehicle was not repaired. The failure and current mileages were 29,643.”
