"engine failure" sign comes on my 2007 BMW 335xi and the engine power significantly cuts off. This has happened to me at least 3 times. The 1st and 2nd time it happened to me, I was driving on the freeway and suddenly, the sign comes on and I lost significant engine power, had to slow down and move over to the right lanes, as I had to drop my speed immediately from 70mph to 55 or lower. Then I pulled over, turned off the car and restarted the car. Sometimes that worked and my engine got full power, sometimes it doesn't and I have to drive with low engine power. The last time this happened to me, 3 days ago, I was in my subdivision and the same light came on, and I lost power. Luckily, it was only my sub, so I stopped the car and re-started the engine. For all the times this happened, I contacted BMW and I believe the did and drive update and replaced the high pressure fuel pump.

My vehicle is 2007 model BMW 335I coupe. I was on the freeway 405 going approximately 70 miles per hour. Then suddenly an engine warning light "engine malfunction" sign comes up which lowers the RPM and the speed output of the engine to around 30~ 40. I have to quickly merge the vehicle from the inner lanes to the right going onto the curb since there was no curb on the inner lanes. After approximately 3 minutes as I slowly guided my vehicle to the side, the engine shuts off on its own with stuttering sound and engine cranking. I restarted the engine several times to no avail. I was extremely dangerous as the sudden slow down and engine shut off might happen when I am in the middle of the freeway and the cars behind or next to me might easily hit me with typical freeway speed of 70 mph. I called the two truck and had the vehicle towed to a BMW center. They inspected the vehicle and believed that the high pressure fuel pump is bad and will replace the fuel pump for me. It appears to be that this very same issue appeared quite often to a number of 335I or other BMW models using the same engine, in particular to the 07 and 08 models. More over, a lot of the car owners have the same issue happened to them even after their fuel pump replaced once or even twice. It seems like there is no absolute fix for such issue and it poses as a tremendous danger for BMW drivers with this specific engine since you cannot be certain when he problem will re-occur. Similar complains have been filed and the action can be referred here NHTSA action number: PE08032.

Long cranks to start up engine and misfires upon cold start up almost every day. Often gets cel but dealer denies warranty/recall work on high pressure fuel pump (hpfp hereon) because I didn't have exact code they are seeking for. They confirmed the symptom but "unless car breaks down on the road or get the exact code, they will not replace failed part". basically saying they will not voluntarily resolve problem unless they are forced to. Hpfp failure on BMW N54 engine platform is already well known fact hence BMW put extended warranty on hpfp. But it's not a recall and many times dealer denies to replace although they confirm the symptom and possible danger associated with the failed parts on vehicles. All they did was updating the dme program that supposedly fix the problem but long crank still happens everyday.

2007 BMW 335I hpfp failed on the highway car stalled and came to a stop as I rolled off the shoulder. A second high pressure fuel pump is indicating that its going to fail and I am seriously concerned about driving it. The car only has 16,000miles and dealer refuse to swap the pump until there is actually failure even though I have exhibited all the signs that the pump is about to fail again. They only provided me a software update. I am seriously concerned for my safety and as a result am not driving this car long distances or on the highway.. I think its about time authorities step up and force BMW to deal with this very serious vehicle hazard, which they are abundantly aware of, but refuse to do nothing about.

The BMW 335I has problem with the high pressure fuel pump failures which was acknowledged by BMW N/a with a extended warranty on this part for 10 years or 120K miles. My BMW 335I has had 3 fuel pump failures in 24,000 miles, each time the car has completely stalled leaving me stranded in very dangerous scenarios. The most recent time I was stranded on a busy road with no shoulder which my safety was jeopardized by this cars default. Numerous attempts to contact BMW N/a have been made, to no avail.

Hi, I purchased a 2007 certified pre owned BMW 335I from weatherford BMW in berkeley, ca just one week ago. Since the purchase, I have had an engine malfunction, loss of power light come up over 10 times. It always comes up when I accelerate on the highway. It leads to a drastic reduction in power, vibration of the car, and causes me to go significantly below the speed limit. I am afraid the car is going to stall on me and that suddenly dropping the speed will result in an accident. It is particularly ridiculous that this was labeled a "certified" car when it started having problems the very next day. I took it to a dealership to get it repaired and they claim the high-pressure fuel pump needs to be replaced. Prior to taking it in, I noticed turning the car off and then on seemed to "reset" it and make the light go away. Still no peace of mind while driving on the highway. I am awaiting repair of the vehicle to see if the issue has been fixed, but reading other complaints on the internet has left me pessimistic that anything is going to be done about this.

Owner of a 2007 BMW 335I coupe. Noticed a problem with rough idles and long cranks at start-up. As time went by, the long cranks and rough idles became more frequent. While driving onto the freeway via freeway on ramp, fuel pump failed while I was merging and engine was cut to half power "limp-mode." Car had significant loss of power and I was almost rear-ended by a semi that was driving in the slow lane.

Failed hpfp for the 3rd time in my 2007 BMW 335I.

Was driving at approximately 55 mph when my car started to shutter. My BMW started to slow despite me depressing the gas pedal. I had to pull off the side of the road even though there was not a good spot to stop. BMW attempted to fix it once by updating the car's software. However, they ended up replacing the fuel pump. It took two service sessions to fix the problem.

Had a high pressure fuel pump (hpfp) failure while driving which resulted in the car going into limp mode (reduced engine power) while driving. This limp mode is potentially a serious safety issue in that if you are on the highway, merging, passing, or around town driving and you get this limp mode you can be involved in an accident due to the vehicle not responding as you, or other drivers, would expect. Symptoms of this issue are long starting crank periods before the vehicle turns over. BMW has know this is a problem for a number of years yet have not spent the appropriate effort to correct the problem. I have had two hpfp failures in the past 11 months (May 2009 and Feb 2010).

Problem with lost engine power in my 2007 model BMW 335I convertible car five times in 2009. One instance involved a fuel line separation on an expressway outside Chicago. Each time the vehicle was taken back to BMW dealership for service. Fuel injectors were replaced. Pollution control devices were replaced. But problem was not corrected. Finally, the high pressure fuel injection pump was replaced and the warranty on it was extended to 100,000 miles. The problem appeared to be resolved.

Driving home my 2007 BMW 335 all of sudden lost horse power. Error message stated "engine malfunction-reduced power". this occurred on an entry to an expressway while trying to accelerate. It obvious the dangers that could happen when the vehicle loses power. I was fortunate enough to pull over and limp to next exit. The dealer ship stated the problem was high pressure fuel pump (hpfp) the is the 2nd time the hpfp has been replaced on my vehicle. My vehicle only has 38K miles. I did further research and this appears to be a common problem. BMW needs to address this before anyone gets injured as a result of this issue.
