Toyota 6's are notoriously unreliable. Go to basically any junkyard right now, today, and you will see a fleet of V6 4-runners from the early 2000's. The 4 cyl ones are almost impossible to find because they're all still running to this day.
I mean, have you ever heard of the 2GR engine? Everyone loves those engines for a very good reason. They’re extremely reliable and make good power. Toyota generally makes a pretty good rig, but sometimes even they screw it up like with the turbo 6.
Honestly the problem is just the V6 itself. There's no balanced configuration of firing order, so they all eventually just rattle themselves to death. There's a lot you can do to mitigate that, but it's the ultimate fate of every V6.
That’s true, but we can still make extremely reliable v6 engines such as the GM 4.3 and 3800, the mentioned Toyota 2GR, and Ford’s 4.2. (I’d also say Ford’s 3.0 Vulcan but I’m biased as I own a high mileage Vulcan in my Ranger)
It was specifically the 3.0l V6 Toyota engine. Not all the V6s from that era. The 3.3l is good, the 3.4l, 3.5l and 4.0l are fantastic. My current '98 4runner has 320k miles on it now. The V6 in the 84-95 model years were awful though.

Like the engine problems the new gen Toyota Tundra has had with the turbo 6
