  • Airbag recall

    Not sure if this has hit Australia as much as it has over here, but there has been a problem with air bags that blow shrapnel as well as the bag when they deploy.
    Since the company that makes the bag supplies to a lot of automakers, pretty much all brands of cars have been impacted. [List at the end].
    I have not blogged about it because as widespread as it was, and as serious as it was, I had not read a single thing on what the root cause was… Till now.

    WASHINGTON — A consortium of 10 automakers investigating the root cause behind exploding airbag inflators made by Takata Corp. has fingered the ammonium nitrate propellant as a key factor in the deadly ruptures — but not the only one.

    According to the group, known as the Independent Testing Coalition, the ammonium nitrate propellant used in about 23.4 million inflators that Takata deemed defective last year was contained in inflator assemblies that failed to protect the chemical from moisture in humid climates. The exposure to humidity and repeated temperature swings over time can cause the ammonium nitrate to combust violently and rupture the inflator when the airbags deploy in a crash, the group concluded.

    So in non-geek speak, the airbag housing itself is the source of shrapnel.
    The gas they used, over time, broke down the container it was in, when the bag deploys, bits of the container come out since it has been weakened.

    customers affected by inflator recalls: Toyota, Honda, Fiat Chrysler, BMW, Ford, General Motors, Mazda, Mitsubishi, Nissan and Subaru.

    That’s a lot of car makers…..

    The inflator defect — linked to 10 deaths and more than 100 injuries worldwide — is already the subject of one of the largest and most complex recall actions in U.S. history, with some 25 million U.S. vehicles affected and suppliers straining to produce enough replacement parts, even as new recall actions are announced.

    Regulators have acknowledged that many of the replacement inflators going into recalled vehicles may themselves have to be replaced later once investigators know more about the overall safety of ammonium nitrate.

    So yeah, if it has not made your news section, be happy. It is a long and expensive recall.
    Did you get that last block quote… The bags that they are replacing the current bags with may themselves have to be replaced in due time.
    This is not going to go anyway anytime soon.



  • Car calls the cops, driver is arrested

    Technology can not lie.

    As ABC 7 reports, 57-year-old Cathy Bernstein was driving her Ford in Port St. Lucie, Florida, on Friday when she allegedly ran into a Ford truck and then a Dodge minivan.
    She allegedly left both accidents without so much as stopping. However, her car was fitted with Sync Emergency Assistance technology. This meant that it automatically contacted the emergency services to say that the car had endured some kind of traumatic event.

    In Bernstein’s case, a recording of her conversation with the 911 dispatcher has emerged.

    She is heard to say: “Ma’am, there’s no problem. Everything was fine.”

    “OK. But your car called in saying you’d been involved in an accident. It doesn’t do that for no reason,” replies the dispatcher. Then she asks a knowing question: “Did you leave the scene of an accident?”

    “No, I would never do that,” is Bernstein’s reply.

    Police appear to think differently. They reportedly went to Bernstein’s house, where they found her Ford damaged. Moreover, officials reportedly found paint from one of the vehicles Bernstein allegedly struck on it. The Ford’s airbag had also been deployed, suggesting the tech had been activated with good reason.

    So, long and short, lady hits other cars so hard the airbag goes off in her car. The IoT stuff in the car auto dials 911 (the police) and the driver tries to just say that everything is fine, but it’s not.
    Before you get all outraged about the tech in the car, you have to turn this feature on on. It is not on by default. The owner had to go through a multi step process to activate this feature at some stage after buying the car.

    Granted, they probably did not think through the fact that the time would come when that feature might revoke their ability to lie.

    Technology can not lie because it does not know what a lie is.
    It just does what it is programmed to do.
