This is an update to ODI 10290275. My car (2009 335xi) is yet again experiencing long starting times and I have had another abrupt loss of power. Although there is no "check engine light" on yet I believe it is only a matter of time before the high pressure fuel pump is again replaced. This is a chronic problem that is recognized by BMW (as they have extended the warranty on the high pressure fuel pumps) but does not address the underlying safety concern of a sudden loss of power that will ultimately result in an accident.

I was driving uphill last night and an engine light came on and the navigation screen said reduced power. I had to shift down into third gear and put my foot to the floor and the car hardly kept going up the hill. I turned it off and then on again and all seemed fine. On the way home the same lights came on but then the service engine soon light came on and began flashing and the car began shaking and idling very rough. The car was very hard to drive and had almost no power whatsoever. Problem occurred again this morning and the car was taken to the dealership on a flat bed. This would be extremely dangerous if it happened at highway speeds or on an open stretch of highway with little access to services and/or repair facilities. The dealership says it is the high pressure fuel pump.

- Brookline, MA, USA

2009 BMW 335I, high pressure fuel pump failure. 9500 miles on vehicle. Engine is slow to start. While driving and RPM above 3000, check engine light comes on and engine reduces power significantly. If pump were to fail completely, engine would die, leaving driver without power steering. This could be a major safety problem on highways with dense traffic. After reading internet blogs on vehicle, this is a known defect for BMW N54 engines. Some drivers have had the pump replaced multiple times with same outcome each time.

- Alexandria, VA, USA

Fuel pump failed on BMW 335I. On the freeway, car information panel indicated "engine malfunction -- reduced power" and the car went into a limp mode, with radically low power and rough running. Because of the prevailing speed of rush hour traffic, my inability to maintain normal freeway speed did not seriously endanger me or other motorists. I am reporting this failure because I have learned that the same failure is epidemic with all applications of the engine in my car. Injuries are inevitable if the defective fuel pump is not redesigned.

Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6) I am the owner of a 2009 BMW 335I purchased August 2009. On April 6, 2010, I started the engine in the morning and was greeted with long cranks and the check engine light turned on with an error message of engine failure, reduced power. The car has been fine before this morning at 7,200 miles approx. I contacted the dealer and was told to bring it in. The car was still drivable. On the way to the dealership, the car stalled and completely lose power on the highway and on the inside street causing me to have to quickly put the gear in P and restart the car. I informed the dealer about the stall and engine failure but was met with no regards. The dealer informed me that it is a high performance fuel pump failure. Please investigate the issue as I do not want to be driving on the highway and have the engine completely stall and shut down again. [xxx]
