Two times in the past five days my 2010 BMW 535xi has shut down. Each time it has malfunctioned(12/24/16 and 12/29/16), the automatic downshift activated). Once while traveling up a hill at approximately 35 miles per hour and once while traveling in excess of 55 miles per hour on a very busy highway. I was not able to restart the vehicle and had the vehicle tolled to a local garage. Shortly after arriving the tow operator started the vehicle. It started without hesitation a second time. I left the vehicle at the repair shop and picked it up four days later. It has started and operated as before until day five when I was traveling uphill and it initiated a downshift and stopped operating. Each time the fuel pump failure indicator came on. It is a scary feeling, especially since each time I was in the midst of other vehicles.

My 3 kids and I had left the BMW dealer after I had parts serviced/parts replaced, and jumped on the interstate. I was cruising around 70mph when I felt the car slow down and the msg "engine malfunction, reduce speed" appeared. I veered to the right a little, but I quickly found and exit and pulled over. Fortunately, the traffic on the interstate was lite and an accident was avoided, but it did get my heart racing. The dealer said this was a "common" type of msg, but I'm weary. I tried telling them about the fuel pump issue, but they said my car was not affected. They wanted to charge me another diagnostic fee and I just paid to have my car serviced and diagnosed! they also suggested I continue to drive it until the issue forces me to have to bring it in - basically until something breaks. I would have the dealer would have started with replacing the high pressure fuel pump and moving on from there since it is a documented problem. We'll see what happens.

I purchased a pre-owned 2010 BMW 535I on 12/31/2013. The next day (new year's day), and without any warning or indication, the vehicle spontaneously shut down, coming to a rolling stop. As soon as the engine shut down, the dashboard showed a "fuel pump" warning, which also noted that "continued driving is possible." However, several attempts to re-start were not successful, and the vehicle had to be pushed to a safe location. Prior to the engine failure, I was driving at about 35 mph on a 2-lane divide roadway, where construction barricades replaced the shoulder. The incident occurred just around midnight, and there was very little traffic, so we were spared certain catastrophe. The vehicle was towed to my home, and although the engine light stayed on, we were able to drive it back to the dealership from there. For the next 30+ days, various fuel injection system components were serviced and/or replaced including the following: High-pressure fuel pump replaced; low-pressure fuel pump replaced; fuel injectors flushed, ignition coils and spark plugs replaced. After each of those "fixes", the vehicle was returned to us, and shut down again on the road and in traffic within 2 days. Finally, the injection pump control module was replaced, and the vehicle underwent a complete software system update. We picked up the vehicle for the 4th time on 2/3/2014, and it appears that the problem has been corrected and our safety restored....

When the temperature hits 100 degrees as it does in the desert 5 months or so per year, the interior cabin fills up with very harmful gas fumes. We owned a 2008 and the same situation. As a result of this and problems with the fuel pump on the 2008, the dealership bought the car back. My husband really wanted another BMW and when he was looking at buying the 2010 he was told all the problems including the gas fumes had been resolved. Not so. The car has been back to service twice for the gas fumes and no one can shed any light on the situation. When this happens you cannot drive the car as the fumes will knock you out. The car has to sit on the driveway and air out for a few days. You can't park in the garage as the gas fumes enter the house. For a car of this caliber it is not acceptable. Plus it is very dangerous to your health.

I was accelerating up a hill on the highway and my car just lost power.

- Mclean, VA, USA

Acceleration for the vehicle was reduced by more than 50%. 0-60 mph was approximately 15 seconds. At least the vehicle was drivable. No warning, no indicator. The warning message did show up the next day.

Recurrent engine failure secondary to high pressure fuel pump in brand new BMW 535I. First failure at 3000 miles; second failure after repair around 6600 miles. Both failures without warning and severe loss of power in high speed traffic.

- Durham, NC, USA

The vehicle suddenly shows an engine malfunction alert and then the power immediately slows down and then I had a minute to try and get off to the right on the freeway before the engine turned itself off. The vehicle was towed to the dealer and was told that it was the high powered fuel pump. There are numerous other people on the internet with the same experience. I am seven months pregnant and am grateful that I was able to get to the right side of the freeway.

- Laguna Beach, CA, USA

At around 3000 miles (2010 535xi), while attempting to accelerate onto highway engine power died - engine light came on, and car eventually stalled. Luckily was in right lane at time so managed to pull over. Tried to start car several times with no luck. Waited several minutes and car did start but continued having acceleration problems. Took it to dealer and had fuel pump replaced. Told it was a common problem.

High pressure fuel pump malfunction/failure.

- New Orleans, LA, USA

Our 2010 BMW 535 xi experienced a failed fuel pump. The car is was purchased new 4 month prior to the failure. The car had a total ~3100 miles when the failure occurred. When the failure occurred, the car lost all power including the power steering which caused a very serious safety issue as the car was in motion with little ability to steer it to safety. The car was towed to the closest dealership where the fuel pump was replaced with a new unit.

Fuel pump on BMW 535I-2010 has failed twice in 60 days on low mileage car. Safety issue occurs because car immediately loses power with no warning. The first time it happened we were in a shopping center garage so we were going slowly. Second time it happened we were on the 101 heading East at high speed on an incline. Lost power and luckily were able to move over to the shoulder with no incident. We were informed by dealer that this has been a continuing problem with this model. They have replaced it twice. The service manager said they have redesigned the fuel pump and hopefully this time it will work. I googled similar problems and found that there were a number of people reporting the "safety" issue of losing power rapidly.

Recurrent sudden stalling of vehicle multiple times, leading to loss of steering control, on a brand new BMW 535 xdrive with 3000 miles. The problem was fixed by changing the high pressure fuel pump, by the BMW dealership. I am not sure if this is widespread problem with BMW vehicles with dual turbo engines.
