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.

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 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.
