2010 BMW 335I Engine And Engine Coolingengine Problems

I WAS DRIVING NORTHBOUND ON A CROWDED STRETCH OF US101 IN A 2010 BMW 335I COUPE WITH LESS THAN 3200 MILES ON IT. MY CAR WAS MOVING AT ABOUT 65 MPH WHEN SUDDENLY I LOST ALMOST ALL ENGINE POWER, MAKING ACCELERATION IMPOSSIBLE. I HAD TO EASE MY WAY OFF THE HIGHWAY AND, AFTER STOPPING TO TAKE STOCK OF THE SITUATION, I DROVE HOME VIA SIDE STREETS. MY CAR CONTINUED TO SUFFER FROM LACK OF POWER ALL THE WAY BACK AND COULD BARELY ASCEND SOME OF THE HILLS. *TR

PROBLEM 1 - ENGINE MALFUNCTION INDICATOR AT STARTUP. CAR DID NOT IDLE CORRECTLY AND RAN ROUGH WHEN DRIVEN. WHEN DRIVING, MISFIRES AND REDUCED POWER. MAX SPEED ACHIEVED WAS 35MPH. *TR

WHILE DRIVING ON THE INTERSTATE AT 70MPH, THE ENGINE MALFUNCTION INDICATOR CAME ON. POWER WAS SUDDENLY REDUCED TO LESS THAN 35MPH. THIS WARRANTED AN IMMEDIATE MOVE TO THE SLOW LANE OF TRAFFIC AND HAD TO GO SEVERAL MILES UNTIL IT WAS SAFE TO PULL OFF THE ROAD TO ATTEMPT A RESTART. RESTART DID NOT HELP, HAD TO DRIVE THE CAR AT 35 MPH TO NEAREST DEALER FOR SERVICE. *TR
