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.

Car hesitated and stopped running on the freeway.
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.
My 2008 bmw 135i started taking 10-20 seconds for the vehicle to start. The problem has been ongoing for a couple of months now. I took the vehicle to a bmw dealer and complained about it. The dealer informed me that bmw informed them that it was normal for the vehicle to do this. And told me that they couldn't change the fuel pump, which has been known to go bad on this vehicle, until a code was detected. Today, while trying to merge in traffic on the highway, the car suddenly had reduced power and I couldn't accelerate. I was very fortunate that there was no car behind me or the incident could have been disastrous. The car also showed an icon on the dash that indicated the car had gone into limp mode or reduced power mode. This is a serious safety issue, which could have resulted in serious injury or death if a car had been behind me. Please look into this problem before someone is injured.
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.
High pressure fuel pump failure on 2008 bmw 135i with n54 3.0l turbo engine. Symptoms were long cranks prior to starting. Replaced under warranty.
Bought 2008 bmw 135i in 7/2008. Within first week of ownership message came up stating "engine malfunction, reduce power" car has been in numerous occasions-each time bmw assures problem is taken care of. Reasons given fuel pump, injectors, gas issue and lastly adjustment not done at factory as it should have. So, car is back in the shop as it again sputters and shakes heavily -trying to pass a vehicle on two lane hwy- vehicle slowed itself to 50 MPH and I was nearly killed by having to pull back in traffic as I could not pass due to lack of power. We plan to file under lemon law-been in multiple times-has occurred 5-6 times and we are done.
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.
