Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Water pump failed while driving and car would not exceed 5mph. Postings online show this is a common issue (possible recall issue like the fuel pump). Car was towed to the dealer and water pump was replaced for $1033.

The car stalled and lost power on highway. Engine light came on. Rough idling. First incident occurred September 2011. The second incident happened Oct 26, 2011. Both times the car stalled and lost power on the highway. I believe that this created a very dangerous and life threatening situation for me and others on the highway.

My BMW lost power on multiple was in BMW service for 6 weeks discovered a problem with manifold "leaking oil and no power to twin turbo. Factory man could not find the cause. They had to tear down the engine finally after we were losing our patience to finally "find the problem". this was when the car was brand new. Have had multiple trips to BMW service for stalling and loss of power on the road. Have had to reset the"cars' "system again on 2 occasions.BMW did extend the service warranty on the turbo and fuel pump. Tonight had complete power failure on highway. Had to stop and start and go several hundred limped home into the garage. Im sure my trip to the BMW service station will be an exercise in futility since they tell me the car is fine. There must be some issue with the twin turbo engine.

Car suddenly looses power and displays "engine malfunction reduced power output." This is scary and upsetting when driving on houston highways with 18 wheelers passing you. You need to safely pull over to the shoulder, restart the car, and the warning goes away, the power comes back and you never know when and where this will happen again. Very unsafe and disturbing.

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.

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.

I am a military officer stationed overseas and do not know how to file a complaint that nearly killed me.

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.

Please refer to the following web site. BMW has a ticking problem with all 2007 and 2008 BMW 3 series. BMW has a tsb to "bleed" the vehicle. BMW is aware this will not solve the problem. BMW needs to replace the cylinder head to fix the defect. BMW has redesigned the 2009 cylinder head to correct the problem. BMW is putting its consumers through a fraudulent scheme to attempt frivolous repairs while knowing a full cylinder head replacement is the only remedy to the problem. Accordingly, I ask that this government service demand BMW issue a recall on the defective component to its 2007 and 2008 BMW 3 series vehicles.
