One problem related to air bag on-off switch has been reported for the 2007 Mercedes Benz C230. The most recently reported issues are listed below.
Takata recall: Mercedes Benz's airbag recall was issued in February 2016 and, almost 2 years later, still no remedy is available. Mercedes has still not offered any repair (or mitigation) for the deadly airbags they installed in their vehicles. It is completely unacceptable that, after two years, mercedes has not been able to develop any repair or mitigation for this deadly defect. How about an "off" switch for the defective airbags until mercedes can figure out how to fix them?.
