    So if the brakes go off, I wonder what kind of scenario might happen. it'd great if Toyota did OTA updates. wonder what the overall cost per car would be to get 4g banwidth - so that process could happen.

    Great...just had the wire harness TSB done a couple of weeks ago. This is getting rediculous.

    This isn't at all unusual.

    When I worked in an office with an attached workshop for our extensive fleet of vehicles - we were a District Office - every Monday Morning's mail included an envelope with TSBs from the Department's Central Office's Mechanical Branch - Technical Service Bulletins (TSB). Initially when I got there in '73, we had Jeep (or Willys?), LandRover, GM, FORD, Dodge and Chrysler vehicles - and later TOYOTA and NISSAN 4WDs too.

    From memory, there were 4 general categories - depending on the brand:
    • Some were marked with something like "For immediate implementation";
    • others were to be done "At Next Service";
    • others were only if a particular issue surfaced;
    • and - others were addendums to the Workshop Repair Manuals.
    I found some of them interesting reading.

    Wonder if this will affect European models also. I've taken my ICS equipment model thought a pull along car wash in neutral a few times with no ill effects.

    As pointed out in the J0R, you can turn off the ICS system. See chapter 4-5, page 352 of the Owner's Manual. This could be a temporary fix before going through a car wash until the dealer work is done. Just remember to turn it back on after the car wash is done.

    Thanks for posting this. I'll ask for it to be done at my next scheduled maintenance. Before this, I had used the Carista app to enable the setting to automatically disable ICS in neutral.

    As for OTA updates, Tesla seems to be the only car company doing it right. The legacy car makers just don't get it. Imagine how much money Tesla saves by not having to do recalls for software fixable issues. While the issue is partially infrastructure for pushing out the update, Toyota also has an extremely janky process for deploying ECU updates that has risk of failing and bricking the ECU. Tesla has a software company mindset, not a car maker mindset, so building a reliable ECU update method is obvious to them.

    I don't think that's it - TESLA have only 300,000+ cars. I suspect the "OTA" hasn't got capacity to update the rest of the 1.1 billion vehicles. TESLA can only do software updates (like this latest update) OTA anyway.

    The 2 recalls I've had so far on PRIUS - you can't install tape on a cable, or a brake modification OTA.

    I think that Tesla's OTA update system could be scaled up to support billions of cars. Smartphone OTA updates go out every month and there are billions of those in use. The bandwidth problem has been solved with things like staged rollouts and CDNs.

    You're right about the tape and the brake fixes. Tesla has had way too many of those types of problems too. While they don't struggle with OTA, they do have serious difficulties with service and repair. I want Tesla software with Toyota hardware!
