NHTSA Complaint #11244509 — 2011 BMW 335IS

THE HIGH PRESSURE FUEL PUMP (HPFP) ON THIS MODEL 335IS CONTINUES TO FAIL AFTER TIME. THE N54 MOTOR WAS INITIALLY RELEASED IN 2007-2009 AND THEN REPLACED WITH THE N55. THE HPFP ON THE 2007-2009 MODELS HAVE NOW AN EXTENDED WARRANTY DUE TO HIGH FAILURE RATES. BMW RE-RELEASED THIS ENGINE IN THE 2011-2013 335IS MODELS ONLY, AND THEY CONTINUE TO HAVE THE SAME CONCERN AS THE FIRST SET OF VEHICLES. AT 54K MILES, MY VEHICLE AT HIGHWAY SPEEDS OF 65MPH LOST POWER AND FORCED ME TO DRIVE ACROSS THREE LANES OF TRAFFIC TO PULL OVER. THE ENGINE COMPUTER STATED "ENGINE LOSS OF POWER, DRIVE WITH CAUTION. IT MAY BE POSSIBLE TO CONTINUE. TAKE YOUR VEHICLE TO THE NEAREST BMW SERVICE FACILITY." AT 82K MILES, I WAS DRIVING THE VEHICLE ON A CITY STREET AND THE SAME WARNINGS APPEARED AGAIN. "ENGINE LOSS OF POWER, DRIVE WITH CAUTION. IT MAY BE POSSIBLE TO CONTINUE. TAKE YOUR VEHICLE TO THE NEAREST BMW SERVICE FACILITY." HPFP FAILURE HAS LOSS OF POWER, ENGINE IN "LIMP" MODE, INITIAL COLD CRANK LAG AT STARTUP, MISFIRES IN ALL CYLINDERS, AND "CHECK ENGINE LIGHT" ILLUMINATED.
