I was driving on the insterstate and the car lost power and would not start. The car was towed to the dealership and required a new fuel pump which cost $1,135.13. Prior to the problem, the gas mileage decreased although the car had been tuned up by the same dealer. The car had approximately 122,000 miles. A request was made to return the old part.

While driving at low speeds, the vehicle lost power. The dealer stated that the software malfunctioned. *ak power loss issue.
2004 bmw 330ci 6 speed manual - 3.0l inline 6 cyl. Intermittent problem - idle becomes erratic and car stalls. This has happened approx 6-8 times over 8 months/5000 miles. Normally happens on warm days and at a stop light/stop sign. It once happened in the middle of a turn which caused me to lose power steering. Dealer has seen the car 3+ times and updated idle control valve, and engine software but problem persists. It is very intermittent and doesn't throw any computer fault codes.
Car suddenly lost power at low, intermidiate and high speed. Car will shake violently, sputtered, then become undrivable. Check engine light came on. Brought in to dealer and was told car has misfired. Dealer proceeded to repair problem by reprogramming computer chip per manufacturer's service bulletin. Was told the car is fixed and safe to drive. 200 miles and on the freeway at high speed, the problem resurfaced. Was towwed back to the dealer nad was told that the air flow sensor and soemthing else was the issue. Replaces both parts. Repair engineer thinks that there is a 99% likelyhood that the problem is fixed. I am not so sure since that said the same thing last time. Since the car is not on the list, it is a bmw 530i sedan.
While driving, the car shook violently, the engine rattled and the car lost engine power; the check engine light went on. The car became immediately un drivable. It was later determined that one of the cylinders in the car misfired and completely shut down, sending the engine into a complete unbalance.
