2007 bmw 335i (build date 11/06): car displays "engine malfunction" and engine power is substantially reduced without any warning or predictability. Turning car off and then restarting resets everything and then the car will run normally until the next episode of "engine malfunction." bmw dealership has checked engine fault codes and believes that this problem is related to premature wear of the "camshaft bearing ledge." I have already had my fuel pump replaced and now the car is behaving exactly the same way but bmw is now claiming another engine fault (camshaft bearing ledge) as the source of the sudden and unexpected engine power loss. I have owned bmws all my life and have never as disappointed with a car as I have with this one. It is my opinion that the engine in this car is so unreliable (unpredictable power loss due to multiple reasons... Not just the fuel pump) that it presents a serious safety hazard for bmw 335i owners as well as other motorists.

I have had my 3rd high pressure fuel pump (hpfp) fail in the 3.5 years that I have owned my car. All three replaced under warranty, but it seems to be a design flaw since this is a recurring problem in my model. Almost everyone people in my car club with a 2007 or 2008 model year 335i has had their hpfp replaced at least once. The car breaks down without warning and generally when comes to a complete stop. Upon failure, the engine warns of malfunctions and continue to drive in a "limp" mode, often stalling when coming to a complete stop...shuddering during the drive until I am able to bring to a dealership. I have been fortunate that all three failure have occurred during low speeds and stalling occurring at stop lights and not during high speed operation. If it wasn't for my bmw roadside assistance, I would have been stranded on one of the three occasions. Bmw knows there is a real problem but refuses to recall. They have issued dealer service bulletins and have increased the warranty on the hpfp replacements for 100,000 miles. However, a 100,000 mile warranty does not fix replacing the hpfp every few months (my 2nd in 4 months). Bmw must issue a recall as this is dangerous and unpredictable, especially since this their is no symptoms for the impending malfunction and there is no user error.
2007 bmw 335i -high pressure fuel pump failure- car is on its fourth pump (original plus three replacements) in less than three years and 30,000 miles. First failure after 8 months and 7,300 miles. First failure was on highway 66 between arlington and mclean virginia at highway speeds. Has subsequently failed at 25 months and 20,900 miles and again at 35 months and 29,200 miles.
First noticed a burning smell -- thought it may be plastic or rubber. Pulled off of the highway near tampa to a local gas station. Looked under the hood, noticed nothing. Then noticed smoke coming from the space where the rear window rolls up, on the drivers side. Smelled like burning rubber or plastic. Called bmw assist, was told to get a tow to the nearest dealer. After about an hour, called to bmw to talk with a service technician -- described the problem to the technician and asked if I could drive the car to the dealership. Service advisor indicated that given the smoke, would advise against driving the car. Car towed to dealership and inspected by dealer the following morning. Dealer advised that the "dash reflected message of pinch protection malfunction. Jbe module caused failure of both rear window motors, interrogate fault memory. Found faults in jbe, a6d9, a6da, a6d8, a6db. Completed test plan for these faults. Per test plan replace jbe. Swapped in jbe from known good vehicle." essentially, the dealer replaced the existing software in the car with the software from a car known to have good software. Dealer found both window motors "burned" and replaced both window roll-up motors. Dealer completed vehicle programming including "cas". Complete car encoding.
Constant failure in my 2007 bmw 335i sedan. Random loss of power when driving on the road. Lights do not light up the path of driving very well. I have taken my vehicle in at least 6-7 times for these issues and it has not been fixed. This is a known issue with this model. I do not know what else to do. I would hope bmw would recall such a defect. Per bmw recommendation I had the engine decarbonized as they said this would make the vehicle run to spec. The fuel pump was recently replaced as it was faulty and a new spark plug put in place. The car now runs rough and the engine is loud. Everytime I take it to bmw they say its running fine. I will bring my vehicle in once again tomorrow to have them take a look at it.
When I tried to make a sharp u turn on a hillside street, the car suddenly accelerated, and stopped with its belly stuck on the curb and the rear wheels in the air after hitting the guard rail across the street. It was so sudden, and the car jumped about 12 feet instantly, and hit the rail. Since the street is sloping down, I never accelerate when I come down the hill. This model has a turbo problem, and the warranty is extended on the turbo part up to 10 years. This car had a several starting problems before, and displayed the "check engine" light. Then it is reset by itself. When the dealer was asked, they denied the possibility of any malfunction of the car. This sudden acceleration looks like a deadly failure. If it happens in a busy intersection, it might have resulted in fatal crashes or deaths of pedestrians.
I was driving my car from florida to new mexico as part of a military change of station. I was on my second day of the trip, from fort worth, tx to portals, nm, when I experienced significant loss of power 5 times in a 200 mile distance (no warning, no warning lights on the dash). Twice, the car turned itself off suddenly, disabling the power steering, with no warning at all. Once was at high speed on the interstate; the other was in the middle of a small town. Thankfully it did not cause an accident either time. This is the first time I have ever experienced this problem and it has happened twice in one day. Bmw of north america has been contacted regarding these incidents. It is a 90 minute drive on very desolate roads to the nearest dealership in lubbock, tx, so I have requested that the car be taken to the dealership for service as it is unsafe for me to drive in this condition. I am awaiting a resolution to my problem from bmw of north america.
2007 335i coupe - car experiences a sudden loss of power while driving at normal speeds. Car omits malfunction warning lights on the dashboard. This car has had this happen now at least 3 times. The previous two times bmw dealer found faulty fuel pumps and replaced. Now, bmw dealer claims the car needs new cam shafts in the car, meanwhile engine has been taken out of the vehicle completely to attempt the repair. It seems like bmw does not want to acknowledge that the car has major issues.
My 2007 bmw 335 sedan was recently updated with a new ecu software update (referred to as progman 29.2) and since then the response has become unpredictable. Particularly the car had no turbo lag earlier and after the update the turbo lag has become very perceptible. This has made highway passing unsafe because the car does not behave consistently and sometimes will hesitate for a few seconds and then surge very quickly and at other times drive normally. The unpredictability and turbo lag makes highway passing quite unsafe especially at highway speeds and given the amount of torque in the car (surges are tough to anticipate). Bmw does not acknowledge the problem and will not even do any tests on the car. They have been sending me in circles between their na office and local dealer.
Multiple incidents with "engine malfunction. Reduced power" aka limp mode. On my 2007 bmw 335i sedan. Bmw replaced fuel pump once, but now seems like the problem is repeating itself.
