It's been a big pain for Tesla as well, where their tiny 8GB emmc on the center screen would fail since they logged to it too much... 134,000 vehicles recalled eventually after they denied it was an issue. https://www.tesla.com/support/8gb-emmc-recall-frequently-ask...

Jesus Christ are they amateurs? These are steel boxes on wheels and we're dealing with the same issues as shitty 200 dollars android tablets from 10 years ago.

That affects the infotainment computer only so driving is unaffected. You just wont be able to check your speed etc. But yeah, it's way too common of a mistake.

I don't know how their cars' UI is designed (and I hope I never have to) but if it's the only way to determine car speed or battery capacity, then this goes well beyond infotainment. No wonder they were forced to do a recall.

I highly recommend people who live in hot environments to keep a spare capacitor on hand. Even if you know how to fix it, if the AC dies when your local HVAC supply store is closed (eg not between 7am-7pm Monday through Saturday usually) you’re either stuck paying out the nose to a contractor who has one on hand during emergency hours or you’re sweating it out waiting for the store to open. While they are readily ava…

It's actually worse than that here in Austin. The was only 1 store that would sell me a individual capacitor when mine failed. That one failed about 3 days later. I did some research online and apparently there was just a massive production run of capacitors that were imported to the US and are known to be bad. Supply houses were just looking to offload them. Now I could take it back for a warranty replacement, which…

I also live in Austin and got my recent capacitor replacement from Johnstone when mine failed on a Saturday and I didn't have a backup handy. It was, IIRC, around $50. Significantly more expensive than Amazon.

I'm offering you a different viewpoint: They made the analysis, how long the flash will live and saw, that it will make it out of the warranty period. Thus they did not opt for more durable and expensive flash and/or software change. I've seen this myself before. One process step before release of the control module was a write cycle analysis to make sure the unit will live for at least 10 years (i think) before the…

You're both missing one of the more likely explanation.. that nobody gave much thought about how long the device would last. "It's solid state electronics, it'll probably outlast the warranty anyway".. I can imagine an aircon company puts a lot of effort into analyzing the air-conditioning unit itself to make sure it lasts at least as long as the warranty, with good margin. But I can totally see them winging it on an…

I'm pretty sure what happens in reality is that someone makes a crappy product and then the warranty claims keep coming and because warranty claims cost them money, they keep improving the quality until the warranty claims stop coming. It's not that they wouldn't improve the quality, it's that the bean counters don't see it in their spreadsheets and thus no time is allocated to engineers building the next revision.

> Purchasing refrigerant requires an EPA number. Why can I buy as many cans of it that I want for my car then? Is the stuff used in house systems that different?

I had some more R134a added to my car recently. The mechanic said when he had his shop, he would have completely evacuated the system to measure how many ounces of refrigerant were still in the system. He also said the old R12 systems were less leaky than R134a. R12 was phased out because of the ozone layer. I think refrigerator and AC repair companies are required to capture and recycle the refrigerant - they don’t…

>I think refrigerator and AC repair companies are required to capture and recycle the refrigerant - they don’t seem to have the equipment to capture and measure refrigerant like auto mechanics.

I'm pretty sure they capture it and then sell it back to you while making you think that that isn't what's happening.
