“The car stalled and lost power on highway. Engine light came on . Rough idling. First incident occurred september 2011. The second incident happened oct 26, 2011. Both times the car stalled and lost power on the highway. I believe that this created a very dangerous and life threatening situation for me and others on the highway.”

“I have had my 3rd high pressure fuel pump (hpfp) fail in the 3.5 years that I have owned my car. All three replaced under warranty, but it seems to be a design flaw since this is a recurring problem in my model. Almost everyone people in my car club with a 2007 or 2008 model year 335I has had their hpfp replaced at least once. The car breaks down without warning and generally when comes to a complete stop. …”

“My serpentine belt (drive belt) snapped and shattered causing my vehicle to lose power steering capabilities. This belt drives all the accesories( alternator, power steering, AC, etc). This is a known issue by Bmw, there is a sib 11 09 08 that states the issue and how to go about checking it by the dealer. The issue is the design flaw in the power steering pully hitting the sub frame and causing damage to the belt and in turn the belt snapping. This can/will cause a fatality one day because of the loss of steering controls. …”

“I was driving my car from florida to new mexico as part of a military change of station. I was on my second day of the trip, from fort worth, tx to portals, nm, when I experienced significant loss of power 5 times in a 200 mile distance (no warning, no warning lights on the dash). Twice, the car turned itself off suddenly, disabling the power steering, with no warning at all. Once was at high speed on the interstate; the other was in the middle of a small town. Thankfully it did not cause an accident either time. …”

“My Bmw lost power on multiple occasions.it was in Bmw service for 6 weeks discovered a problem with manifold leaking oil and no power to twin turbo. Factory man could not find the cause. They had to tear down the engine finally after we were losing our patience to finally find the problem . This was when the car was brand new. Have had multiple trips to Bmw service for stalling and loss of power on the road. Have had to reset the cars' system again on 2 occasions.Bmw did extend the service warranty on the turbo and fuel pump. Tonight had complete power failure on highway. …”
