12 V Battery Problem Forces Toyota To Recall 1.8 Million SUVs (arstechnica.com) 62

An anonymous reader quotes a report from Ars Technica: There's plenty of fear, uncertainty, and doubt about electric cars and the potential risk of battery fires, but the regular old 12 V battery is responsible for Toyota issuing a recall for more than 1.8 million cars this week. Toyota says the problem is due to differences in the sizes of replacement batteries -- some have smaller tops than others, and if a smaller-top battery isn't held in properly by its clamp, the battery could move under hard cornering, letting the positive terminal contact the clamp, causing a short-circuit and possible fire risk.

The problem affects 2013-2018 RAV4s -- about 1,854,000 of them, according to Toyota. The official National Highway Traffic Safety Administration safety recall notice has not yet been posted, but NHTSA's Office of Defects Investigation has had an open case looking into the problem since February 2021, after 11 complaints about "non-crash thermal events" starting in the engine bays of RAV4s. Toyota says that it's working on a new hold-down clamp, battery tray, and positive terminal cover. Once those are ready, the automaker will replace those components for free. The automaker says owners should be contacted about the recall by late December.

    If you've ever seen a RAV4 or CRV on the road, its clear the drivers are a greater risk to death and destruction. And this has nothing to do with the gender of the driver. If you drive one of these vehicles and wonder what I'm talking about, get off your cell phone and go take a driver education course. Once you pass those two tests, you'll understand what I'm talking about.

    The article could be better, but it stooped low and went for the click bait by mentioning EVs completely unrelated to the affected RAV4s. The RAV4 affected models are 2013-2018. Why even mention electric vehicles?

      Because EV fires make the news so much, it's important to point out that no, this is not about EV fires, it's about ordinary ICE vehicles catching fire.

      Normally ICE cars catching fire don't make the news, but I guess when millions of vehicles have a risk of fire, it becomes newsworthy. In specialty media, anyway.

      • But this doesn't mention ICE vehicles, or whether the 12 V batteries are located in traditional ICE vehicles or EVs. Some EVs *ALSO* have 12 V batteries, so it's important to explain whether the affected 12 V batteries are located in traditional ICE vehicles or EV vehicles. But the article fails to do that. The article is lazy and just leaves it as an exercise for the reader to figure out whether 2013-2018 RAV4s with 12 V batteries are ICE or EV.
        • 12V batteries shorting out, regardless of the location, is not newsworthy to the segment of the population who are keenly interested to know if they're EVs. They only want to read car-fire stories that might confirm their view that lithium ion batteries are too dangerous to use.

          The info mentioning EVis there in the article so that those people know to scroll on to the next headline.

    • The summary mentioned that the vehicles in question are RAV4's, which are either ICE or hybrid. Also the headline itself mentioned that these were 12v batteries, I.E. the batteries that are in every ICE car to run the starter motor and other electrics before the alternator becomes engaged.

      You had no need to rush to the slobbering defence of EVs.

      Further more, this is Toyota, a Japanese car maker that will typically fix issues before they become serious. I had a recall on my Honda Integra 14 years after

          I thought everybody who is technical understands that EVs also have 12v batteries for their auxiliary functions, and the OP obviously does so. I thought it went without saying.
          The headline did not even make me think of EVs, but TFA mentioned that it was nothing to do with EVs in case people who know nothing about cars might assume that "battery" must mean EV.

          • The headline is ambiguous. You don't know whether it's about ICE or EV. The slashdot summary begins talking about EVs right off the bat. EVs have 12 V batteries. This creates the impression that the issue would affect EVs. That's just bad/misleading writing. My guess is the author didn't know that EVs also have 12 V batteries, and therefore didn't even understand they were creating a misleading situation. Nowhere does the article clarify the issue affects ICE vehicles and not EVs.

      Because this is extremely relevant. About a third of people have great difficulties introspecting and creating a consistent world view, and as a result they have limited capacity to understand reality devoid of double think. They feel comfort when they believe they have achieved equilibrium with knowledge and are done with it forever, any curiosity or wonder at discovery is replaced with foreboding and anxiety at having to deal with new information. Thus when anything new comes along, it’s hard for even the few trusted people in their thought verification chain, like a pastor, ‘News’ caster, or political leader, to pound the sizeable square peg into that tiny smooth round hole. Part of continuing to be the shepherd of such a flock, and the financial gain and power it provides, is to reinforce that rigid belief structure through fear. For undertaking rational discourse and putting self reason at the helm dissolves the authoritarian power structure and leaves the followers in a disastrous mental state of atrophy after a lifetime of neglect. But more importantly, it severs the revenue and power streams keeping the few privileged at the top in power, and they handle it slightly less well than ripping meth out of an addicts hand. Thus it’s imperative to create a continuous fear stream around anything new or unrealized to keep them hooked and the profits flowing.

      Shit, that was rhetorical wasn’t it? I’m terrible at just absorbing that and not rationalizing it all the way down.

  • Interesting here that Toyota seems to be taking responsibility for replacement battery compatibility. They are recalling their vehicles to account for a different-specced replacement battery.

    That's pretty impressive to be honest - rather than put the burden on whoever is replacing the battery to make sure it fits snugly, they are modifying their vehicles post-release at their own cost to accommodate a wider range of batteries. Unless these are Toyota replacement batteries, not third-party?

Although automotive battery sizes are somewhat standard, the tolerances are quite large. Apparently requiring the owner to fit a Toyota approved battery is not an acceptable solution to the NHTSA, so they have to adjust the clamp and provide a positive terminal cover.

Furthermore you don't want to encourage really odd factory only batteries which will quickly become vendor lock in items like happened with cell phones.

        And why would the NHTSA require the owner to buy another battery that meets the power specifications as well as passed NHTSA regulations when the one they bought already does that. Also the battery being slightly smaller on the top should not be an earth shattering change. I changed out car batteries before and slight physical differences are normal. It seems like the problem is that car was not designed to accommodate a replacement battery being slightly smaller.

This let the battery rock back and forth, with the battery terminal banging off a strut tower brace. The terminal cover was a pretty simple little clip on thing, and had clearly been knocked off or come off somewhere along the line. Maybe from banging on th

          That's why it was better back in Detroit's glory days, when battery hold-downs were made of real metal.

          Of course, they routinely rusted out after a few years, and I had at least one car where the battery just slid around loose in the tray. If only I had seen this article back then, I probably would have tried to fix it :)

Those do break frequently on some cars because of the plastic they chose to use. I've personally never seen a plastic battery hold-down bracket. Not saying they don't exist, of course. They've all been metal, usually the J-hook type with two threaded rods and then a metal bar that goes between those rods. Most have a rubbery or plastic piece molded over the b
