BMW Recalls Vehicles Due to Fire Risks - Ammons Law

BMW Recalls Vehicles Due to Fire Risks

By Rob Ammons

BMW is recalling more than 1 million cars and SUVs due to fire risks under the hood. Repairs will start on December 18th of this year. BMW recommends that these vehicles remain outdoors until they have been repaired.[1] The recall includes the 328i, 328xi, 328i xDrive, 525i, 525xi, 528i, 528xi, 530i, 530xi, X3 3.0si, X3 xDrive30i, X5 xDrive30i, Z4 3.0i, Z4 3.0si and Z4s Drive30i vehicles from 2007-2011.

How do these cars catch fire? First, you have to understand how an internal combustion engine works. Combustion, is the basic chemical process of releasing energy from a fuel and air mixture.[2]  In an internal combustion engine, the ignition and combustion of the fuel occurs within the engine. The engine partially converts the energy from the combustion to move the car. The car’s engine consists of a fixed cylinder and moving pistons. The expanding combustion gases push the pistons, which rotates the crankshaft. The crankshaft moves the vehicle’s wheels.[3]  BMW cars use a Positive Crankcase Ventilation (PCV) system, which is a one way passage for blow back gases to escape in a controlled manner from the crankcase. The PCV system draws out fumes from the engine like a vacuum and acts as a buffer against oil being drawn out. [4]

BMW installed a heater to prevent the PCV from freezing in cold temperatures.[5] But, the PCV valve can corrode and rust overtime, increasing the risk of a fire. Wiring in the heating and air conditioning system can also overheat and cause connectors to melt, also increasing the fire risk, even when vehicles are unattended.

If you or a loved one has been injured by a fire that started in one of these BMW vehicles, you may have a potential claim for damages against the manufacturer. The Ammons Law Firm and its team have the legal resources and experience to assist you. Call (713) 523-1606.
