Coding Error Sends 2019 Subaru Ascents To the Car Crusher (ieee.org)

An anonymous reader quotes a report from IEEE Spectrum: [A] software remedy can't solve Subaru's issue with 293 of its 2019 Ascent SUVs. All 293 of the SUVs that were built in July will be scrapped because they are missing critical spot welds. According to Subaru's recall notice [PDF] filed with the U.S. National Highway Transportation Safety Administration, the welding robots at the Subaru Indiana Automotive plant in Lafayette, Ind., were improperly coded, which meant the robots omitted the spot welds required on the Ascents' B-pillar. Consumer Reports states that the B-pillar holds the second-row door hinges. As a result, the strength of the affected Ascents' bodies may be reduced, increasing the possibility of passenger injuries in a crash. Subaru indicated in the recall that "there is no physical remedy available; therefore, any vehicles found with missing welds will be destroyed." Luckily, only nine Ascents had been sold, and those customers are going to receive new vehicles. The rest were on dealer lots or in transit.

    The world doesn't need another lumbering bovine of a full-sized SUV anyway. And Subarus have, in general been porking up over the years such that even the Outback and Forester are too damn big now as well. WRX or BRZ, or GTFO.

  2. Not that affects everything everywhere by SuperKendall · · Score: 2, Interesting

    Right, because humans never make a process mistake that applies to more than one unit on the production line?

    Yep, it's Slashdot, there's always gotta be that one guy that makes you explain a joke in GREAT DETAIL. Ok then.

    Humans making a process mistake do not generally do so in a way that instantly applies to EVERY production line across multiple facilities, in places where the process was working just fine previously. Also P.S. the joke was about workers, not people defining the process. A process mistake would affect workers and robots the same way so is irrelevant to the joke.

    I'm not saying it's impossible for humans at the topmost level to make mistakes on this scale where human workers all do the wrong thing. But with robots it is tons easier for mistakes to be distributed instantly everywhere to "workers" on the line and affect many more units more quickly.

    I don't even think It negates the advantages of having robot production lines, it's just an interesting and (to me) kind of funny aspect of production automation. There are a whole host of interesting consequences and probably behavior that follow from this if you think forward instead of being pedantic about a joke.

  3. What do you mean, "can't be fixed"? by hackertourist · · Score: 3, Interesting

    How is it not possible to run a welding torch over the weak seams? Sure, it's a couple hours to remove the seats and some trim, but that's still got to be a lot cheaper than scrapping the whole car.

      So use a spot welder rather than a torch, and duplicate the intended welding pattern. Still not rocket science.

      I suspect there are two things at play:

      1) It's probably much more difficult to get to the spot than makes sense. Once 2nd and 3rd assemblies are put together it may simple be too complicated to bother with.

      2) The liability. If this car is in an accident and that patchwork weld fails it will cost them a lot more than 293 cars cost.

    I kind of doubt this car with its manufacturing defect will ever hold any significant value. It's quite likely that even if you decide you're going to keep it, the VIN will be invalidated in the system meaning that you will not be able to license and insure it, so forget about driving it on public roads.

    As recalled vehicles go, a more interesting example would be the late 80's Nissan Van. After Nissan recalled the van several times and failed to correct the tendency of the vans to overheat and self-immolate, Nissan gave up trying to fix them and attempted to buy back every single example at above market value and sent them all to the crusher. However, Nissan couldn't actually force anyone to sell their van. So despite all of this, a handful of owners decided to keep their vans anyway, making surviving examples extremely rare today. However, rare doesn't mean valuable, and it seems that the van is considered more of an oddity or a curiosity rather than something collectable.
