For those curious without reading: > The front power seat motor on the affected vehicles could overheat because of a stuck power seat slide knob, potentially resulting in a fire and increasing the risk of injury. (Not what I was expecting.)

Neither and considering the integrations of car systems, surprised this isn’t a OTA update

  It sounds like a standard electrical switch that moves the seat could get stuck/wedged and the motor will continue to try and move the seat indefinitely. There's no software involved.

    There's definitely software involved, just probably not OTA compatible https://www.continental-automotive.com/en/components/seat-comfort-systems.html https://www.continental-automotive.com/en/components/seat-co...

    Although, either the motor should be designed so that it can successfully run forever in this case (maybe draining the battery but too bad), or, so that it fails entirely after some period, it shouldn't catch fire as that's definitely not what you wanted. Hence, presumably, the safety recall.

    Times of physical switches being directly wired into 12V motor supply are long gone.

  Kia/Hyundai have been kinda slow when it comes to rolling out the ability to update cars OTA (although I don't know if other legacy automakers are any better). I think the first model to support full OTAs was the Ioniq 6 in 2023. It's still gradually being added to other models when they get refreshed. I do wonder how the cost of adding OTA support compares to doing software updates the old fashioned way. My Ioniq 5 can only do OTA updates for the infotainment, and when there's been recalls to perform non-infotainment software updates it's required a short dealer trip that I assume Hyundai corporate pays for. Across all of the cars they've sold, I imagine that gets expensive

    For legacy automakers it is a small miracle to get any software updates, much less OTA updates.

Shouldn't this motor have thermal overload protection that prevents it from reaching a temperature that would allow it to start a fire? I'm not sure how smart the seat moving system is, but it seems like it could also refuse to run for more than 60 seconds in a row, or incorporate limit switches or back EMF detection to stop when it reaches the end of travel.

  It should! It doesn’t. Hence the recall.

  Yes, the motor should have thermal overloads and/or limit switches connected to it, but this is Hyundai we’re talking about. I’m not surprised they shaved a few cents off the BoM after they caused a car theft epidemic by saving a few bucks by leaving out a simple anti-theft device that every other manufacturer includes. Why anyone buys a Hyundai/Kia after the last couple years is beyond me, I’ll never own one.

    Because Kia/Hyundai makes very good and reliable cars and those are facts backed by lots of data. The only brands that are more reliable are all in Japan, with 3 exceptions (Mini, BMW, Porsche) being German.

      Reliability should be looked at by model, not by brand, because if you buy a BMW in the US for reliability, you may have a bad time considering the most available models there. And I will always go for repairability, that's why I will advise to only buy models with easy electronics and reliable mechanics so that the only shit that can fail me are the axle (which is cheap to repair) and the motor (which isn't). And preferably look at how much a second hand car with the same model is worth after 2 years, that tell a lot about a model reliability.

I don't really see how an overheating motor could catch fire. I tried! All there is is a bunch of metal with maybe a few plastic bits and enamel on the wire. It would probably create a disturbing amount of smoke though so it seems like a prudent move on their part.
- quickthrowman 2y ago
  It might not be the motor itself catching fire, the motor conductors could heat up enough to catch on fire.

Pure negligence, monitoring for stall current is practically free with modern motor controller chips.
