The contact owns a 2008 BMW 535xi. While driving approximately 65 mph, the accelerator pedal was engaged and the engine began to sputter with an extensive reduction in power. The contact continued with caution and the vehicle was taken to a dealer where they replaced the fuel pressure sensor, spark plugs and performed an oil change. The failure persisted. The vehicle was taken to the dealer three times in which there were no resolutions. The high pressure pump was replaced on a different occasion. In addition, when encountering a bump in the road and down-shifting from third to second gear, an abnormal clicking noise would occur. Recently, the engine warning indicator illuminated. The vehicle was in the process of being diagnosed. The failure mileage was approximately 45,000. Updated 01/28/11 updated 02/07/11

My 2008 BMW 528I has now shifted into neutral, and then down-shifted, at high speed (60mph) without warning 4 times. Three of these incidents occurred on the freeways of los angeles. This latest incident almost caused me to be hit by multiple cars as I coasted to a gorepoint at a freeway offramp.

When engine is cold, car will not shift into reverse. It must be shifted into drive before it will shift into reverse. The first time this happened was in August-September 2007. The gear shift was replaced by the dealer. It happened again in October or November, 2008. The dealer downloaded all the software related to gear shifting and re-loaded it. The shift worked about one month until it happened again. As soon as I can get the car back to the dealer, they will have a third opportunity to fix the same problem.
