Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering fuel system on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Service bulletin - The MIL comes on with DTC P0300 (random misfire detected) or P0301âP0304 (cylinder misfire detected). Carbon buildup on the intake valves may be affecting combustion.

Use a commercially available valve cleaner to resolve the carbon issue."

The failure pattern owners describe
Owners of 2018 Honda Fits consistently report stalling, loss of power, and fuel-related symptoms that Honda has flagged under recall 23V858000 (Fuel System, Gasoline). One owner's Fit entered limp mode, stalled, and emitted a strong fuel odor around 100,000 miles; diagnosis showed fuel running too rich, but intake valve cleaning twice did not resolve the failure. Another experienced power loss with warning lights at 30,000 miles; fuel injector and spark plug replacements at two different shops failed to fix recurrent stalling.
Several owners report unintended acceleration while idling, abnormal shaking, and burning odors in the cabin. One reported fluid leaking from the dashboard onto the floormat during a stall at 25 MPH, resulting in foot injuries. Dealers frequently cannot duplicate these failures or clear fault codes, leaving owners without answers.
The most consistent theme across complaints: recall 23V858000 parts have been unavailable for an extended period, with manufacturers confirming delays and some owners reporting the recall notification process itself was slow to arrive. Multiple owners state Honda exceeded a reasonable repair timeframe.
