DualSense stick drift is common and recurs on replacement controllers
French owner forum thread where users report PS5 stick drift; the quoted user says the only real fix is replacing the stock sticks with magnetic ones (soldering or ~30-50€ shop repair) and warns a new 75€ controller will drift again within a year.
What to check. Stick drift is the most commonly reported PS5 controller fault. It affects the DualSense regardless of console model, so budget for it; a replacement controller may develop the same fault, and a magnetic-stick swap is the longer-lasting fix.
CE-108255-1 crash error on PS5 Slim Disc Edition when joining online matches
A PS5 Slim Disc Edition owner reports crashes with error CE-108255-1 specifically when entering online matches; a separate French forum thread calls CE-108255-1 a recurring Sony error code on PS5, usually resolved by clearing cache or reinstalling the game.
What to check. CE-108255-1 is a known PS5 crash error code. It is often a software/data issue (clear cache, rebuild database, reinstall the game) rather than hardware, but if it persists across games a repairer may suspect the internal SSD. Try the software fixes before paying for hardware diagnosis.
Liquid metal thermal interface degrades with age, causing overheating and shutdowns on older disc-model PS5s
A repair technician documented a CFI-1116 (a disc-model revision) with severe overheating from degraded liquid metal; the article also cites Reddit owners of launch-day PS5s shutting down after 20-30 minutes, fixed by replacing liquid metal and thermal pads.
What to check. On an ageing PS5 Disc, overheating/auto-shutdown after years of use may be the liquid metal interface degrading rather than dust. This is a repair-shop job (liquid metal replacement), not a DIY fix, and the article notes it does not affect every unit.
PS5 Slim shuts down under load in native PS5 games (Sonics bus error)
A repair-forum case documents a PS5 Slim (EDM-052 board) that crashes and fully shuts down under load in native PS5 games, with Syscon logs showing a Sonics bus error (B0088108) and SSD controller watchdog timeout.
What to check. A PS5 that powers off only under heavy game load (not in menus) points to a hardware/power fault rather than software; the Syscon error log is what a repairer reads to diagnose it. This is a single-unit repair case, not evidence of a widespread defect.
Disc drive can fail to read discs or trap a disc; Sony ships a manual eject procedure
Sony's official support documentation for the disc model covers disc-reading problems and a manual procedure to remove a disc stuck in the drive (using a screw on the drive), confirming the disc drive is a serviceable part with recognized failure modes.
What to check. For the Disc edition specifically, the optical drive is the part unique to this model. Sony's own guide documents reading faults and stuck discs and provides a manual eject screw, so a stuck disc is recoverable without sending the console away, but drive faults are a repair-shop item.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
