2010 BMW 550I Engine Problems

I have been having issues , not sure what the problem is but the car doesn’t seem like it’s getting proper gas , & it shakes when I drive . I had to park it in the garage after having it towed home due to an unknown issue .

On 11/10/21 I was advised by Long Beach BMW (Long Beach, CA) that my car needs a new engine. The car smells of gas (both when running and when sitting) and burns excessive amounts of oil. The car requires a quart of oil every 200 - 400 miles. The first engine was replaced after only 77,000 miles because the car was stalling unexpectedly. Now, the current engine needs to be replaced after only 51,000 miles because the car smells of gas (likely because the fuel injection system is not working properly) and because it is burning excessive amounts of oil. BMW expects me to cover the cost of a new engine even thought there is an obvious defect. I contacted BMW of North America and they offered to take the car back & give me $2000 toward a new car. There is currently a recall because of engines at risk...

LOST OF POWER WHILE DRIVING, 2 INCIDENT: BAD VIBRATIONS WHILE AT A IDLE.

FROM A VERY SLOW ROLL THERE IS A DELAY IN ENGINE RESPONSE OF 1-2 SECONDS. THERE IS ALSO A DELAY IN ENGINE RESPONSE IN THE 10-30 MPH RANGE OF THE SAME LENGTH OF TIME. THE SLOW ROLL EVENT CAN CAUSE CONFUSION TO OTHER DRIVERS WHO BELIEVE YOU ARE YIELDING THE RIGHT AWAY WHEN YOU DO NOT ACCELERATE IN A TIMELY MANNER GOING FORWARD OR MAKING A TURNING MOVEMENT. THERE IS THE POSSIBILITY OF AN ACCIDENT IF A PEDESTRIAN, BICYCLIST OR ANOTHER CAR TAKES THE DELAY AS A SIGN THAT THEY HAVE THE RIGHT OF WAY. THE DELAYED ENGINE RESPONSE IN THE 10-30 MPH RANGE IS OF GREAT CONCERN WHEN ATTEMPTING TO MERGE ONTO A FREEWAY FROM A SHORT ON-RAMP IN MODERATE TRAFFIC. THE ENGINE RESPONSE DELAY IS VERY PRONOUNCED UNDER HARD THROTTLE AND HAS CAUSED HEAVY BRAKING BY CARS UNSURE IF I'M GOING TO BE AT SPEED WHEN MERGING. *TR
