One problem related to oil pump has been reported for the 2012 BMW 650. The most recently reported issues are listed below.
At approximately 120,000 miles my engine oil pump went out causing my car to stall while on the highway traveling at 70 miles per hour. The BMW dealership said to me that even though my car meets the miles specifications the engine oil has metal pieces in it therefore they will not cover a new warranty under their lemon law. BMW new that this engine was a troubled engine from the first dat this car was built and now BMW is not standing behind thes vehicles.
