2009 BMW 335I has had engine run at half power numerous times. Only once was it able to be taken to the dealership in time for them to retrieve any diagnostic information and act on it at that point in time, however it has suffered similar behavior since this point and supposedly they are unable to retrieve data, even within a week or two of the event occurring and state that nothing is wrong with it. The first time this happened I was making a left turn and was relying on the acceleration of the vehicle to make a turn at a reasonable speed prior to traffic arriving and the car simply gave out and reduced itself to half power (per the error on the screen). Quite nearly got me in an accident. The filing date on this is the most recent, to my knowledge, of the incident occurring. I wasn't aware of this site until now so it's possible the date is off by as much as 4-6 weeks.

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]
