2018 Honda Clarity
The 2018 Honda Clarity came in three distinct versions: the Plug-in Hybrid (PHEV), the Electric (EV), and the Fuel Cell (FCV). This analysis focuses on the Plug-in Hybrid model, as it was the most widely available of the three. The 2018 Clarity Plug-in Hybrid features a 1.5-liter four-cylinder engine paired with an electric motor, producing a combined 212 horsepower and 232 lb-ft of torque. The engine mainly acts as a generator for the electric motor and can directly power the wheels at higher speeds. The Clarity Plug-in Hybrid is known for its impressive electric-only range (around 47 miles), spacious interior, and comfortable ride. However, some common dislikes include its unconventional styling, somewhat sluggish acceleration when the battery is depleted, and limited availability of certain features.

- Recalls: None Found
Summary:
The 2018 Honda Clarity Plug-in Hybrid, while a fuel-efficient and spacious vehicle, has exhibited some common issues. While some are relatively minor, such as headlight condensation or infotainment glitches, others, like battery degradation and engine hesitation, can be more concerning. The cost to address these problems varies significantly, ranging from a few hundred dollars for software updates or bushing replacements to potentially several thousand dollars for battery module or head unit replacements. While the issues aren’t universally reported, potential buyers should be aware of these potential problems and carefully inspect the vehicle before purchasing, and also ask for service history to verify the vehicle has been updated to mitigate the issues.
