High pressure fuel pump is bad in car. The car goes into limp mode on highway when passing car leaving you no power to get out of the way of car going 75 MPH. Bmw knows it bad but will not help!

At 8,532 miles my bmw 135i had a high pressure fuel pump failure that caused my car to decelerate below the speed of traffic. At 24,384 miles the car illuminated a engine caution for over temperature. The only gauge available was for oil temperature which did not indicate hot. There was not a shoulder to pull over for 3 miles.

I own a 2009 bmw 135i with the n54 twin turbo engine. One day I was driving down the interstate at 70mph when suddenly the car lost all power and suddenly decelerated. A warning lamp on the dash came on indicating the car was only operating at half engine power. The car was running very roughly and shook and shuddered violently when I pressed on the accelerator....I was unable to maintain a vehicle speed above 50mph. I finally had to pull off the road and let traffic pass. When I put the car in park it was still shaking and heaving. I reported this immediately to the bmw service department where I purchased my vehicle. While I was told it was due to the high pressure fuel pump, I was told that bmw was unable to offer any resolution at this time. Since then, this has happened three times, each time in heavy rush hour traffic. I feel that this is extremely unsafe and is likely going to result in a serious accident. Bmw is aware of this problem and yet seems to be unable to solve the problem. Many other owners of the 135i, 335i and 535i have reported similar instances. Will you please encourage bmw to recall these unsafe vehicles before somebody is hurt or killed?

2009 bmw 135i high pressure fuel pump failure. This has been a bad problem with 3 model years (2008, 2009, and 2010) of bmw 135i cars. Luckily my car was fixed due to long start cranks before the common symptom of engine dying during driving conditions.

My 2009 bmw 135i began experiencing "long cranks" when attempting to start the engine cold. While driving at freeway speeds the car began experiencing intense vibration when accelerating. Following the vibration, the car experienced lack of power and engine light was illuminated. This could result in loss of control at highway speeds and should be further investigated due to the frequency of this problem with bmw's hpfp. The dealership updated the cars software and replaced the high pressure fuel pump.

Vehicles affected: bmw 135i, 335i, 535i...any bmw using the n54 engine will have a part called the high pressure fuel pump. Mine has failed on me twice, the first time the pump failed I was stationary. Second time the pump failed I was driving at 60km/h and tried to accelerate to overtake...the pump failed and vehicle had shut off and instant loss of power causing cars to rapidly brake. This is a serious issue and can be dangerous if the problem happens randomly and unexpected. Bmw has tried to address this issue by issuing new parts...I have obtained new parts and I am on my 3rd pump and this is showing signs of failure.

Even though it shows a bmw 135 on the vehicle description this is for 2009 bmw 335i, it does not have that choice on the menus. Also I did not include the VIN number because the vehicle is still in germany and has never been registered in the USA.. At least until this april when I get back there if I don't get rid of it before then. While driving approximately 60 MPH on any surface, the check engine warning indicator illuminated on the instrument panel and the vehicle would go on "save mode" loosing power. The warning indicator remained lit until the engine turned off. This will happen all the time... The vehicle was then taken to an authorized dealer and after a week of troubleshooting and contacting bmw it was determined that the hp fuel pump was the problem and it was replaced. Three months later the car started to take too long to start when cold so back to the dealer and it's been there for over a week and the last update I received was that they might have to change the fuel pump again. This is a brand new car built in april 2009 which I picked up at bmw here in germany with us specs. The car has around 7k miles.*cw

There is no model option for a 335i or 335 xi for 2009. This needs to be changed. There was a sudden loss of engine power on highway. I was surrounded by other vehicles including trucks doing approximately 70 MPH. I came close to getting rear ended when my car suddenly slowed without any brake lights and I could not go faster then 40 MPH. This is the third failure of the high pressure fuel pump, (hpfp) on this 2009 bmw 335i. The dealer replaced the hpfp again but expects the failures to continue as bmw has not provided any resolution for the hpfp failures and safety risks associated with same despite this problem existing for four model years.

My 2009 bmw 335 I with xdrive exhibits slow starting, turbo lag, decreased fuel economy and performance. This has LED to a few instances where I have been unable to quickly move out of the way of oncoming traffic, merge with quickly moving traffic, etc. I have taken the car to the dealer on multiple occasions. On two they replaced the high pressure fuel pump. Recently, the car started exhibiting the same symptoms and I was forced to take it back to the dealer. I am currently waiting on the outcome. The car has less than 10,000 miles on it.

I have 2010 bmw 135i with a fuel pump issue. It is being replaced right now. This model is known for having a fuel pump issue since it was debuted and bmw has yet to address the issue. People have replaced this pump 3 or 4 times with no permanent resolution. Leading up to the failure are long cranks, odd idling and engine lights. In certain scenarios, the car will go to "limp" mode leaving it practically un-drivable and could cause a danger if you are in traffic.
