Understanding the Honda CMX300 recall history

The Honda CMX300 currently has 3 recall campaigns indexed from the NHTSA public database. Each recall represents a formal campaign to fix a defect at no cost to the current owner. Owner complaints are self-reported incidents that haven't (yet) resulted in a recall but can indicate emerging patterns worth watching.

The most frequent recall categories for the CMX300 in our dataset are engine (1), and steering (1). These clusters matter when you're shopping for a used CMX300: recalls in these systems tend to be the ones most likely to have been skipped by previous owners, because they aren't always visible during a routine test drive or pre-purchase inspection.

The tracked recalls span model years 2019–2025, with campaigns reported to NHTSA between 2019 and 2026. Not every model year carries every recall. Each campaign is scoped to a specific year range and often a specific build window, which is why a VIN lookup is the only way to know whether a particular CMX300 is actually affected by any of these campaigns.

How to use this page

The safest path for an owner is to run your VIN through the checker above. A VIN query hits NHTSA's live API and tells you whether your specific CMX300 has an open, unresolved recall. If you're researching a used CMX300before buying, use the recall list below to understand the model's full history, then check the seller's VIN to see whether prior owners actually completed the free repairs. Many don't, and unresolved recalls can linger for years.

Figures are generated live from the RecallScanner dataset, which is sourced from NHTSA's public recall and complaint APIs and refreshed daily. RecallScanner is independent and not affiliated with Honda or any U.S. government agency.
