Fuel Pump problems of the 2008 BMW 135

Vehicle is a BMW 135i, model year 2008, convertible. Car suffers sudden and complete loss of power at high speed and often during high-traffic, rush- hour speeds on moderate incline sometimes with minimal safe shoulder and median. This the 6th incident over the last year and a half. BMW of san diego replaced fuel pressure sensor and multiple high-pressure fuel pumps. We have barely avoided multiple accidents. We are scared to drive our car.

My BMW 135i has 16,000 miles on it and I have had to high pressure fuel pump failures. The car is unreliable and dangerous.

While driving on a busy, 45-mph road, my car lost power suddenly and began to shudder when I applied the gas pedal. I was losing speed and unable to accelerate. I had no choice but to put on my hazard lights, and pull into the nearest parking lot I could find. After researching the problem, along with scanning the car for any error codes, I discovered that the high pressure fuel pump (hpfp) had failed and needed replacement. Oddly enough, this was the 3rd hpfp that has failed on this car.

High pressure fuel pump ( hpfp ) failed. Driving my '08 BMW 135i the car started running rough. The next day it stalled on a road and had to be towed to a BMW dealer who replaced the hpfp.

I would often hear a liquid pumping sound on when put onto reverse after ignition. Serviced at BMW dealership but they oddly were not able to replicate the problem. I could replicate it every time. One night the car started with long cranks. "reduced power" warning came on and car was sluggish, jerky, and could not go above about 30 mph. Took it in to dealership. The fuel pump was replaced with new pump. I asked how come it wasn't replaced when I reported the problem earlier. They said they don't replace it until the pump actually dies. This is not a very safe practice.

I was going approx. 65mph in 5th gear in my 2008 BMW 135i coupe when the car stuttered and I got a service engine soon light. Brought my car to BMW service and my service advisor told me that I have an issue with my fuel pump and it needs to be replaced. The car only has around 5000 miles on it.
