Unknown oil leak started around 75k. noticed it in my garage. i've only had this car for 2 years.
3 days after receiving an oil change and brake pad change, while driving on a city street at approximately 25mph my car spontaneously switched into neutral and i could no longer accelerate. my dashboard stated that i had a drivetrain malfunction and that maximum output was not available. i proceeded to take my car into bmw in order to get a diagnosis. when i received the diagnosis i was told that my engine was non operable and i would have to pay ten thousand to change engine. the technician stated it was because of an internal engine failure, and that the reason for the failure was unknown but it was more than likely a bad oil filter. my vehicle has had two recalls concerning oil and i am concerned that it is a manufacturing defect. thank you
This is now a repeat problem (3 times). driving at speed on local roads the car drops to idle speed and there is no response from the gas pedal. this morning i had just gotten the car back from bmw service and was driving back to work when the same thing happened. this time it happened as i was turning across the oncoming traffic lane and i was let basically stationary in the oncoming lane.
The vehicle can't handle heavy rain with medium sized puddles. the owner's manual clearly states, "drive through calm water only if not deeper than 9.8 inches, no faster than walking speed up to 6mph." this puddle was under 4 inches as i measured and took photos, but bmw refuses to warranty the work. they claim the engine hydrolocked resulting in full replacement of the engine. a quick trip to google and you will see many people complaining of the same issue. we were the only car disabled. 2 dealers admitted to engineering flaws, but laughed at bmw covering the repairs. bmw usa was of no help either.
