Not sure if this qualifies as planned obsolescence but Acer stopped supporting a tablet I bought in less than two years. I have been avoiding Acer products ever since.

Dishwashers, the 3 most recent dishwashers that I have had experience using across 3 very different households and use levels, from 3 different manufacturers, have all had minor to major faults in the 4-5 years since installation, just after the warranty period ended.

Mostly drawer and roller related, but also a pump failure.

New appliances. A matter of time until the fridge chokes itself since the coils are covered in dust and impossible to reach without tipping the whole fridge over. Also sorely regret replacing the old electromechanical washer instead of repairing it. New one fills with too little water at random and apparently it's a controller board issue with no easy fix in sight.

Also Apple mobile devices, I understand they can't keep supporting them forever, but the bootloader's locked so I can't even put something less demanding on it.

Windows 11 refusing to install on hardware it can absolutely run on.

IP rating on smartphones so there's seals and glue everywhere and opening them up is a fucking nightmare.

Washing machines. In the stores, you see a shiny stainless steel drum, but holding up the drum is a raw aluminum spindle. Those spindles corrode with typically caustic laundry detergents to last about 6 years. Replacement was possible, with a day of work. Now, manufacturers seal the drum unit with welded plastic so replacement is impossible.

Probably doesn't count as I didn't buy it, so I'm technically not dealing with it. But let's talk about electric riding lawnmowers. Last year I was looking to replace my 20+ year old riding lawnmower with an electric one. Could not find a single manufacturer who would also provide the parts lists. Digging deeper, seems like they simply do not sell parts, like at all. The mowers just aren't repairable - straight up, if it breaks, buy a new one. That's irresponsible when talking about an electric drill, but a full riding mower? WTF?

To be fair, this might be a chicken & egg problem. Low adoption rates means there's a very small market for parts, so there's no aftermarket support. And that aftermarket is where I get parts for my current mower. So maybe it's not fair to blame the manufacturer? But I think that's a stretch. From where I'm standing, it sure looks like intentional planned obsolescence.

Win11... The amount of perfectly good hardware that became ewaste in October is insane to me

Samsung Galaxy S8 Pro. It's one of these curved phones with glass on the back.

The front glass is hardened Gorilla Glass. The back glass breaks when you're looking at it wrong. Because of the curved soapbar style, the phone easily slips out of your hand, shattering the back glass.

I am very delicate with my phones and never broke one in all of my life. The S8 was the final boss for me, though. I had to have the back glass repaired two times, one time it just fell off of my bed which is only 15cm above the floor. Fuck you, Samsung.

I've never personally dealt with them and don't ever intend to get a Switch 2 so I probably won't deal with them, although I can imagine them being catastrophic when Nintendo eventually sunsets the console in question, but Switch 2 Game-Key Cards.
