BMW recalls 394,000 older vehicles equipped with Takata air bags
What models are affected by the BMW recall?
The BMW recall affects certain BMW 3 Series Sedans and Sportswagon models manufactured between 2006 to 2012, including models powered by four-cylinder and six-cylinder engines that run on gasoline or diesel fuel6. The vehicles may be equipped with Takata air bags, which can explode and send metal fragments flying at the driver.
Why can the Takata air bags explode?
Takata airbags can explode due to the use of ammonium nitrate as a propellant, which can break down over time, especially in high heat and humidity2. This breakdown can cause the propellant to burn too quickly, creating excessive pressure that ruptures the inflator and sends metal fragments flying.
What modifications concern regulators in recalled vehicles?
Regulators are concerned about certain vehicles that may have been modified by owners to include sport or M-sport steering wheels, which use airbags made by now-defunct supplier Takata. These airbags have been known to explode and send metal fragments flying, posing a significant safety risk.
