Takata Recall Affects 46 Million Vehicles in U.S.

Takata Recall Affects 46 Million Vehicles in U.S.

Takata's airbag recall affects over 46 million U.S. vehicles. As of June 2017 65% HAVE NOT been replaced. (Reuters)

If unable to promptly get a replacement and worried about what could happen in a crash, then you can request from NHTSA to install an airbag On-Off Switch. Here is the NHTSA link: http://www.safercar.gov/Vehicle+Shoppers/Air+Bags/ON-OFF+Switch+Requests

Airbag Recall Technology

Airbag Recall Technology

When the inflator assembly is activated, sodium azide produces nitrogen gas which flows through the filter screen and into the airbag. Time between crash detection and complete airbag deployment is approximately 0.05 seconds. Typical airbag deployment speed is 200 mph. If the inflator assembly is structurally defective the inflator assembly can explode,

GM Ignition Switch Defect

GM Ignition Switch Turns OFF

A fundamental problem with the design of this ignition switch assembly in that the key can easily rotate to the ACCESSORY position which turns off the engine.

Turning off the engine affects vehicle controllability and turns off the airbag systems.
