This looks to me like a "cold shut", which is a type of casting defect. "Cold shuts occur when two relatively cold streams of molten metal from different gates meet and do not fuse together properly during the casting process. This problem is visible to the naked eye – giving the appearance of a crack separating the two sections." https://www.haworthcastings.co.uk/news/the-differences-betwe... Cracks caused by impact…

Is there a functional difference? Would cracks from a cold shut not disqualify the product (whatever it is) from going into service?

I think it’s safe to say cracks in a structural member are always bad. I think the point the OP is making is that it looks like a manufacturing defect not the result of a crash.

Any sort of defect like this should disqualify the product. It’s embarrassing and alarming that this casting wasn’t scrapped.

That's just normal flash memory degradation when you are using low quality chips. It's very common, especially among low end Samsungs. It's not something that can be fixed on the software side.

It was really very rapid in the Nexus 7 for me, though. I think my iPad Air 2 has it to an extent now, say, but it’s _9 years old_; it is somewhat understandable. My 2012 Nexus 7 was starting to behave very badly a year in.

Were you doing any rooting, flashing of custom roms, large i/o operations like video stuff or similar? The average flash memory chip quality of that era (depending on the supplier) wasn’t great, they can’t handle as much read-write cycles as typical modern consumer silicon.

Nothing as reliable as a Honda Civic or Toyota Prius.

Some people love to claim that electric cars will be more reliable due to mechanical simplicity. And yet somehow the highly complex Prius is still far more reliable and durable than any Tesla. It turns out that simplicity doesn't help if your engineers and assembly workers are incompetent and badly managed.

Toyota Prius is one of the simplest currently made ICE cars. There is nothing simpler and more reliable than port injection inline 4 engine and eCVT transmission.

Edit:

And naturally aspirated engine.

The weirdest part of this to me is the customer. You knew the manufacturer had a reputation of forgetting hard to check parts ... and you still bought one. What else could it be missing that you can't practically check for? Still I guess at least it's good to see Tesla living up to the reputation for American cars to be generally shit build quality. I feel like they're going a bit overboard on that factor though.

It's a status/whatever symbol, build quality doesn't really matter. I've a friend that drives a Model 3 and said "it's just like driving a BMW" and of course he has never driven a BMW.

These people are interesting.

Anyone who has so much as sat in a mid to top tier car from BMW/Mercedes/etc will instantly come away with an overwhelming sense that a Tesla feels cheap by comparison (because it does). Classic things like the sound and feel of closing a door, gripping a steering wheel, pushing a button, etc.

If you pay attention to detail this can often be experienced from the car externally - famous cases of Tesla tending to have poor tolerances and high variability in things like panel gap, etc.

My bet is that becomes a scenerio where the party with the most money for lawyers wins. If it was me, I would have almost no money for lawyers.

Having recently dealt with this very situation. Lawyers are honestly not __that__ expensive for these disputes and NDA’s are largely unenforceable.

Was it with Tesla? Curious what happened..

It's still a serious structural defect.

The importance of the distinction here is that Tesla can't argue the customer caused this...a cold shut can only happen at casting time.

Normally cast metal parts shouldn’t have issues detectable with optical inspection system. I worked for a company doing welding inspection systems. It is absolutely crazy when such part ends in the final product. This company clearly overstretched cutting corners on this.

Would a part like this get x-ray inspected? I had a summer job working at a machine shop and structural castings would often get sent for x-ray inspection.

It’s the best way and most expensive. For mass production of automotive parts probably too expensive. I mean these guys can’t or don’t want to afford 20000$ camera system for quality assurance.

It's one car, so I don't want to pretend like it's every car, but certainly Tesla has earned a reputation at poor quality control. It seems obvious to me they optimize for factory output even at the cost of delivering a correct product. Anecdotally, a close friend had a Model S Plaid. He took delivery roughly a year after they were announced. Tesla forgot to install weather stripping in the frunk. "Flood" is too stro…

They also prioritize manufacturing capacity for new product at the expense of replacement parts.

Many Tesla owners have had the experience of waiting forever for replacement parts because of an accident, component failure, etc. A minor fender bender can result in having a damaged (potentially undriveable) Tesla for months whereas for other cars you're reliably back on the road in a week or less.

Unfortunately when people are so emotionally involved with something be it a CEO, a brand or a religious group they will go through all kind of brain gymnastics to not really blame them. Look at the child abuse in the catholic church (and all the others that are just barely starting to be known), their congregants protected the priests too and found all kind of excuses.

This definitely seems like a little Stockholm syndrome. You see it also when it comes to doing a chargeback against a company that defrauded you. Inevitably someone will say "But, if you do a chargeback, the company will close your account and ban you!" These people have gotten to the point where the company has stolen their money, and they still want to continue doing business with them! A lot of simping for companies that don't deserve the affection.
