Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2020 Clarity.
The 2020 Honda Clarity represents Honda’s foray into electrified transportation, blending the brand’s compact‑car platform with a hybrid powertrain that delivers both efficiency and practicality. With only three owner complaints reported for the model year, it stands out for its overall reliability, and notably none of those concerns are tied to manufacturer recalls. The single area where drivers have voiced issues—Forward Collision Avoidance—highlights a specific safety feature rather than a systemic problem, underscoring the vehicle’s strong safety pedigree. In the broader context of the Clarity’s reliability history, this low complaint count signals a mature, dependable platform that has proven its resilience over successive years.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2020 Honda Clarity dominate in one area — the forward collision avoidance, 1 of 3 reports (33%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the forward collision avoidance pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
