    Class Action Suit On BMW N54 Turbo Engine For Defective High Pressure Fuel Pumps and

    Here at BMWBLOG we don’t only report on positive BMW news, but we also cover any topics that are less favorable to the brand. Objectivity has been and will always be our main goal, and any valuable story will make its way onto our pages.

    With this being said, we wanted to bring forward a class action lawsuit initiated by the legal firm of Kershaw, Cutter and Ratinoff, LLC of California, that alleges BMW produced the N54 engine which suffers from serious defects.

    This isn’t the first lawsuit on the N54 fuel pump failures and BMW has previously acknowledged the problem and offered affected owners an extended emissions warranty.

    According to the law firm, the problem with the turbochargers is that defective examples cannot run at full capacity, resulting in strange noises underhood and noticeable throttle lag.


    We have first covered the BMW N54 fuel pump issues in early 2008 and the article has been the most commented story we have every published here at BMWBLOG, with over 350 people presenting their concerns, suggestions and feedback.

    Before we jump into the lengthy press release, we would like to present BMW’s response to this lawsuit through a short statement issued for Autoblog.

    We are reaching out to BMW for more details. Stay tuned!

    BMW has discovered that certain 2007-2010 model year vehicles may experience partial failure of the High-Pressure Fuel Pump (HPFP) which is part of the direct fuel injection system on certain 1 Series, 3 Series, 5 Series, X6, and Z4 models. Specifically, vehicles powered by the twin-turbocharged 3.0-liter inline-6 engine (internally dubbed “N54″) are affected. Symptoms include long engine starting times and sometimes the illumination of the Service Engine Soon lamp in the instrument cluster, possibly accompanied by reduced engine performance (Fail Safe operation).

    As a result, BMW will extend the emissions warranty coverage period to 10 years or 120,000 miles, whichever comes first, on affected vehicles in all 50 States. If the HPFP fails during the extended warranty coverage period, BMW will replace it with a newer-production version. Customers who experience long starting times or notice the Service Engine Soon lamp should contact an Authorized BMW Center to schedule a service appointment. Customers with further questions should contact BMW Customer Relations at 1-800-831-1117 or email customer.relations@bmwna.com.

    The aforementioned fuel pump is evidently prone to failure, and when they go south, the car loses power and goes into ‘limp mode’ since it can’t drink gasoline. Such failures could have serious safety ramifications depending on when and where the pump packs up. According to Autoblog sister site Daily Finance, this isn’t the first lawsuit regarding N54 problems.
    Press Release:

    Class Action Law Firm takes on BMW for Systematically Concealing Safety Risks of Defective High Pressure Fuel Pumps and Turbo Chargers

    Lawsuit alleges that BMW systematically concealed information from the public and the National Highway Traffic Safety Administration (NHTSA) regarding defective fuel pumps and their risks to consumers.

    Flawed engine design of BMW twin turbo models leaves consumers stranded

    Sacramento, CA (Vocus) October 5, 2010

    Sacramento, California based class action law firm Kershaw, Cutter & Ratinoff, LLP, recently filed a class action lawsuit on behalf of thousands of individuals who own various BMW vehicles released between the years of 2007-2010. The lawsuit, No. CV10-2257 SI filed in the Northern District of California, seeks to compel BMW to initiate a recall in order to replace all of the high pressure fuel pumps (HPFP) in the affected vehicles.

    According to the complaint, in 2006, BMW announced with much fanfare the development of its new N54 twin turbo engine. BMW touted the new engine as incorporating state of the art technology that included dual turbo chargers and a newly developed fuel injection system. BMW represented to the public that this new technology would eliminate ‘turbo lag,’ a common problem in turbocharged vehicles, and that its new state of the art fuel injection system greatly increased the performance and fuel efficiency of its vehicles.

    Plaintiffs allege that the new engines that were so highly touted by BMW in fact contain serious design flaws that render the vehicles unsafe to drive. There are essentially two design flaws at the center of the case. First, the plaintiff asserts that BMW’s new fuel injection system that supposedly incorporates a new ’state of the art’ fuel pump actually malfunctions at an alarming high rate. As a result, many BMW owners have had to repeatedly replace their fuel pumps, sometimes within 1,000 miles of vehicle ownership.

    Lead attorney on the case, Stuart Talley of Kershaw, Cutter & Ratinoff, noted, “When these fuel pumps fail, the car comes to a complete stop or loses substantial power. If this happens while someone is driving on a highway at high speeds, this can create a very serious safety hazard. We believe the defect is so significant that it makes these cars unsafe to drive.”

    The second problem relates to the BMW turbo chargers. Specifically, the complaint alleges that owners of the affected vehicles were told that BMW’s new engine had eliminated ‘turbo lag.’ ‘Turbo lag’ is the delay between the time that driver of a vehicle presses the accelerator and the time that turbo chargers on the engine essentially ‘kick in’ to provide added power to the engine. However, shortly after the vehicles were released, BMW began to receive complaints from owners that they were hearing strange noises from the engine along with a delay in throttle response. BMW eventually discovered that these problems were the result of a design defect in the turbo chargers.

    Plaintiffs allege, however, that rather than repair the defective turbo chargers, BMW implemented a secret ’software fix’ to hide the problems from consumers. Any time a consumer brought their BMW in for repair or routine maintenance, BMW would ‘upgrade’ the vehicle’s software. This software tweak kept the turbo chargers from operating at full capacity, ensuring that their defects would go undetected.

    Apparently owners aren’t happy. A number of user generated forums, petitions and blogs have cropped up criticizing BMW for their handling of the issue. On the BMW Blog, several consumers reported their BMW’s going into ‘limp mode.’ They also complained of excessive power loss and ‘turbo lag,’ the very condition BMW said it had eliminated with its ’state of the art engine.’ The plaintiff’s complaint seeks to force BMW to repair the defective turbo charges and/or reimburse consumers for the diminution in value to the vehicles.

    Kershaw, Cutter & Ratinoff have demonstrated their dedication to protecting the legal rights of consumers, as well as their ability to devote substantial resources through trials involving large corporations. Their product liability lawyers have represented thousands of victims of defective vehicles and dangerous products in cases throughout the United States, generating hundreds of millions of dollars in lawsuit recoveries for their clients and the classes they have represented.

      Unfortunaltely, this is not a terrorist act, therefore it shall remain confined to the US.

      Otherwise, they would have bombarded half the world to get revenge. :lol:

        It won't, and the maximum they would get is an extended good-will programme.

                Ignition and Recall Timing: A Tale of High Pressure Fuel Pump Failures

                Well the intertubes are all in a dither now that BMW has recalled cars for the failure of some High Pressure Fuel Pumps (HPFP) on its turbocharged direct injected engines.

                To begin with the recalled cars have two fuel pumps, a primary low-pressure in-tank pump, and a secondary high pressure pump near the engine itself. The low pressure pump isn’t really all that low pressure, it’s a 5 bar pump (about 70 psi) and if you’ve ever dealt with carburettors you’ll know that’s about 10 times more than you’re used to.

                The secondary high pressure fuel pump is the enabling technology on a gasoline direct injected engine. The really high pressures that pump develops can overcome the pressure of the turbocharged slug of air that is then further compressed in the cylinder. The timing sequence of fuel injection and spark is directly dependent on the high pressure fuel pumps operation.


                If the high pressure fuel pump fails, the engine can still operate on the 5 bar pressure from the primary fuel pump. What it can’t do, at that point, is utilize as much boost pressure or ignition timing that allows such high power from small displacement as its owners are used to. In essence it will still run, but it will run like a four cylinder, automatic transmission, Camry.

                What BMW and the supplier of the high pressure fuel pump have been doing in the past year or so is isolating the cause of the failures, developing a workable engineering solution to the problem (that won’t introduce additional problems), testing the solution, and the deploying the fix into the field and gather feedback on its effectiveness.

                BMW has told BMWBLOG that they have a revision of the HPFP that has been in service since March of 2010 and that they are satisfied that it is providing the reliability they expect.

                That leads directly to the buzz surrounding the recall. Cars are not recalled because a couple of executives and a lawyer get scarred after a news story.

                Responsible companies that have an issue with a defective part first acknowledge the problem. They then assure customers that they will provide a fix and possibly will reinforce the warranty on the defective part. They will then work closely to identify the cause of failure, engineer a solution, and thoroughly test it. At that point, with a proven solution in hand, they will issue a recall for the superset of potentially problematic parts.

                This is what BMW has done. They acknowledged the problem with the high pressure fuel pump, and before they had a fix in hand, they extended the warranty on the HPFP. Then with a fix in hand, they worked with authorities (in the case of US cars,NHTSA) to issue a voluntary recall. At most, the news story pushed up the timing of the announcement.

                There are 150,000 cars that are subject to recall, the actual number of defective HPFP is some subset of that. That being said, it’s much more fun to buy into the conspiracy theory that without the dogged pursuit of our media, nothing would have been done about this. But I can guarantee you that most in the media wouldn’t know what a HPFP is if it bit them in the keester. I still wouldn’t monkey with the Cuomo’s though .
