Mini cooper keeps leaking oil which can be dangerous for road safety. There are Lawsuits going on but company has not recalled their vehicles to fix oil leak issue. It has cost consumers thousands of dollars in repair, time loss & mental harassment. Company is aware of the issues and has not done anything. These cars are not safe to be driven & sold in the USA.
