BMW 750 I xdrive 2011 --excessive engine oil consumption and or burning. The design of the valve stem seals is a major safety problem due to excessive oil consumption. The safety concerns are the following: 1) fire hazard. 2) property damage and personal injury 3) polluting the environment with excessive smoke 4) additional cost burden for consumers every time the vehicle is stationary and at the point of acceleration, the is a tremendous amount of smoke that is coming out of the tail pipe. The oil measure turn to low after just 2 weeks of adding oil to the engine. For the following reasons, BMW should be held accountable and be forced to repair the engineering design flaws in their engine that burn excessive amount of oil in a short amount of time. Consumer should not have to carry the cost burden of repairing this design flaws. As an owner, I am very disappointed in BMW
