Owners have reported units overheating badly enough to warp and deform the plastic housing. In one such thread, the owner reported that Roku support said they were aware of the issue and were tracking its frequency. Evidence is limited to a small number of reports — treat this as a caution, not an established pattern.
Real comments from Reddit, linked to the original thread. Nothing paraphrased.
When I picked it up, I noticed it was really hot, and felt weird. When I turned on the light, the bottom was warped and malformed. No signs of burning around the power plug, just heat warping. ... Worried this could have become something more and started a fire...
This button isn't launching the app but Roku makes a sound as if the signal was received.
They were concerned, but stated that they were aware of the problem and are noting the frequency.
Make sure that you plug something else into that port on your TV, and verify that the Roku burning up just didn't damage that Port or render it unusable.
"The Roku Express 4K Plus' Voice Remote which is network-based"
Of 5 tracked mentions, 3 are negative, anchored by a single detailed report of a unit that overheated, warping its casing badly enough that the owner worried about fire risk — Roku support acknowledged awareness of the issue and said they were "noting the frequency," though this appears to stem from one documented incident rather than a wave of independent failures. Separately, a voice-remote app-launch bug is reported, where the remote's sound confirms a button press but the target app doesn't open. On the positive side, the network-based Voice Remote is called out as a genuine step up. Given the single overheating report and unresolved remote bug, this is fine for casual streaming use but worth watching — anyone with heat-sensitive electronics setups or media cabinets with poor airflow should keep an eye on the unit and avoid leaving it running unattended for long stretches.
