Complaints about fuel pump failures on BMW models equipped with the N54 twin-turbocharged, 3.0-liter I-6 have been the subject of Internet debate and media scrutiny for quite some time. BMW has now officially issued a voluntary recall, designed to rectify the situation in roughly 130,000 cars.
According to BMW, the high-pressure fuel pump may fail on certain models equipped with the N54 engine. Should this happen, the car will enter a so-called limp home mode, which cuts engine power. Drivers may possibly notice a drastic reduction in engine power, sluggish acceleration, along with an engine warning telltale lamp, service engine soon screens, and prolonged crank times.
BMW says the following N54-equipped models are subject to the recall:
-2008-2010 135i coupes and convertibles
-2008-2010 535i sedans and wagons
Although this spread covers 130,000 vehicles, BMW estimates that 40,000 of the vehicles will require a new fuel pump and software updates, based upon their service history. BMW is still urging all owners to have their vehicles inspected at a dealership, even if the vehicle isn't exhibiting any of the above symptoms.
Additionally, BMW is also recalling select X5 crossovers built with the normally aspirated, 3.0-liter N52 inline-six-cylinder engine. According to the automaker, 2008 X5 3.0si models may witness low-pressure fuel pump failure, which could stall the engine, which subsequently would strip the driver of power brakes and steering assists. BMW believes roughly 28,000 vehicles are subject to this recall, although no reported injuries have been tied to the issue.
BMW will send owners of affected vehicles official recall notices within the next few weeks, urging them to bring their cars into an authorized BMW service center for inspection and repair.
