Driving on the highway, engine stops. First warning "engine malfunction, reduced power. But it had already stopped. After narrowing missing traffic parked in breakdown lane. Next warning fuel pump failure. Car would not re-start for an hour until tow truck arrived. Had to be towed to BMW dealer. Dealer reports low pressure fuel pump. Engine died again at dealers

- Stow, MA, USA

The car suddenly displayed a warning saying the fuel pump malfunction and gave a notice that engine may shutdown immediately and to pull to a side. We complied - though it may have been pretty dangerous if we were on highways or in traffic. Tried to start again, the same issue. Got it toed to the BMW dealership. The dealer diagnosed the issue to be the high pressure injection pump and told us it is not covered. We called BMW and they told it is now covered as it has an extended warranty. We tell the dealer and the dealer tells us it is covered but another part edk pf is now not covered as it did show fault codes that were earlier than the fuel pump fault codes. My issue is if the fuel pump and edk work hand-in-hand, won't the two to be covered by BMW" why it should matter, which did show fault codes first" infact this is pretty dangerous situation and I wish BMW recalls and checks all vehicles and fix all the parts that are affected.

Vehicle shutters and misfires when automatic transmission downshifts while attempting to accelerate at cruising speeds. Engine light comes on and has reduced power until vehicle is restarted. Major safety concern when attempting to merge onto highway.

I was driving on the highway and all of a sudden when I tried to switch lanes, the car just made a big fumble and almost stalled. The traffic behind nearly became fatal as the car did not accelerate and I was very luck to have pulled back with the passing car barely hitting my mirror. I have taken this car to the dealer on many occasions and they have changed out all the injectors and still the car is having this problem. Every time I go to the dealer they keep changing the fuel injectors or recalibrating them. A simple google search will show that this is an on going issue with these cars and BMW of North America does not want to do anything about it. Even though this was reported before the end of the manufacturer's warranty and still ongoing, they refuse to cover the repairs. This is absurd and they should be held responsible as my family and my life is in danger every time we take to any road with this car. We are not in a financial position to afford repairs as it is very expensive and unfortunately we are forced to take a risk every time we have somewhere to go. My pregnant wife and my self has missed almost 20 times where another car could have hit us. I fear one of these days we will not be so lucky. Please help.

In the 4 1/2 years that my 535xi has been in service, the fuel injectors have needed to be replaced 3 times (Sept 2011, Jan 2013, and Sept 2014). The problems have manifested themselves when driving on highways and the vehicle loses most power and begins shaking and the check engine gases light comes on. The most recent time occurred while on an interstate tollway between exits 15 miles apart making for a dangerous situation as I lost speed and any ability to accelerate. Efforts to have BMW cover the repairs (estimated at $2,200 including new plugs), were both unsuccessful and frustrating. The dealer provided zero assistance. I contacted BMW na and stated that having to replace the fuel injectors 3 times in 4 1/2 years indicates a defective design and results in dangerous situations. I was told that they would investigate and inform me whether the repairs would be covered. They said they would notify me within 3-5 business days although they would try to expedite the process since I was without a car. At the end of the 5th business day, there was no response so I called and the person I needed to speak with was in a meeting and was supposed to call me back. After another full business day and no call, I called a again and was told that there was no coverage but they did not provide any rationale. This has been a repetitive and dangerous problem.

My first incident occurred while I was traveling on I-185. My vehicle suddenly lost power and began sputtering and check engine light came on. This happened while traffic was heavy but miraculously I was able to merge over to the emergency lane and exit off the interstate. BMW dealership diagnosis it as a failed in-tank electric fuel pump and sensor. It was repaired and I paid $1254. Unfortunately, a week later, I experienced another loss of engine power and check engine light came on while I was traveling on the interstate. This time BMW dealership told me they had to upgrade software and change out some injectors and that should solve my problem. I bought this car to drive it and not send it back and forth to the repair shop.
