GarageCalc What the data says
Engine accounts for about 33% of this year's Honda Accord complaints. That is a moderate concentration; worth knowing, but complaints are spread across several areas.
The 2018 model year contributes 253 complaints (27%). Older vehicles dominate, consistent with age-related wear rather than a new defect.
Complaints are up year over year, 719 to 927 (+29%), against a market that rose about 2%. Year-over-year movement is the most useful signal here: a model's sales are roughly stable from one year to the next, so a sharp rise means the per-vehicle complaint rate genuinely moved, not just that the model is popular.
How to read this
Raw complaint totals track how many Honda Accords are on the road as much as they track quality, so a high count on a best-seller is partly a volume story. Complaints are also self-reported: they capture what owners chose to file, not a controlled survey. Use these numbers to know where to look during a pre-purchase inspection and which recalls to check, not as a verdict on their own. Compare any car instantly in the Car Complaint Checker, or read the full 2026 study for the market-wide picture and methodology.
