Only time will tell.
I've been seeing the same person on social media posting their propaganda that every PlayStation 5 with the original liquid metal design from launch is doomed to fail if it's not serviced by a repair shop every three years.
They even insulted their followers who questioned whether this is a widespread issue, by stating their conclusion is based on diagnostics and basic chemistry and physics from middle school.
It is undeniable that the liquid metal issues will affect some systems, but without an official statement from Sony, which has shipped over 80 million "PlayStation 5" units, it's premature to characterize this as a widespread issue.
According to this expert, I should have had my PS5 serviced in 2023, and again in 2026 and 2029 (after which my console will be archived). It would cost me anywhere between $495 and $600 for these three services (I'm assuming this can be handled locally; if not, there would be additional shipping and handling costs).
Considering the PS5 I've had since launch has never overheated, and its fans have never run at full force for an extended amount of time, I would be better off saving my money and purchasing a new unit if it fails.
Instead of insulting their followers, wouldn't it be better to post tips on how PS5 failures can be mitigated by placing the unit horizontally, keeping the unit clean, and avoiding moving the console right after heavy use? Here's a useful video with general tips:
I'm going to make a bold prediction that if I follow these tips, my PS5 will work fine after the PS6 is released.
