Honda Clarity Best & Worst Years: The Complete 2025 Encyclopedia of Reliability, Types, Safety & Ownership
🔍 Definition & What Is Honda Clarity? (Complete Overview)
Honda Clarity is a groundbreaking series of electrified sedans produced from 2017 through 2021. It offered three distinct types under one nameplate: Plug-in Hybrid (PHEV), Fuel Cell (FCEV), and Battery Electric (BEV). The Clarity was Honda’s flagship eco-car, built on a dedicated platform with a spacious five-passenger cabin, high safety ratings, and futuristic styling. Unlike compliance cars, the Clarity PHEV quickly became a favorite because of its 47 miles electric range (still class-leading in its era), combined with a gasoline engine for unlimited range. This article answers every question: what are the best and worst years, why certain years fail, how to inspect a used Clarity, advantages over Prius Prime or Tesla, and is it truly safe?
🏆 BEST YEARS (⭐⭐⭐⭐⭐)
2021 · 2020 · 2019 (PHEV only) — Reliability rating 9.2/10. Honda perfected the infotainment, battery thermal management, and suspension tuning. Very few owner complaints; excellent residual values. The 2021 Touring trim offers leather, premium audio, and Honda Sensing standard. Why best? No mechanical weak points, robust battery degradation (less than 5% after 4 years), full EV range usable year-round.
Top Pick: 2021 PHEV Best Value: 2020 PHEV
⚠️ WORST YEARS (Avoid if possible)
2017 Honda Clarity Fuel Cell + 2019 Clarity Electric (BEV) — The Fuel Cell model suffers from hydrogen fueling infrastructure scarcity (only parts of California), extremely high fuel cost ($16-20/kg) and low resale. The 2019 Electric gives only 89 miles of range, slow DC fast charging (50kW max), outdated for modern EV standards. Avoid both unless you have very specific needs.
Worst Overall: 2017 Fuel Cell Avoid: 2019 Electric
📅 Year By Year Full Analysis: Reliability, Recalls, Common Issues
| Year | Powertrain Type | Reliability Score | Key Issues / Strengths | NHTSA Complaints | Verdict |
|---|---|---|---|---|---|
| 2017 | Fuel Cell only | 3.8/10 | Worst: Hydrogen station unavailability; fuel cell stack degradation in cold; few service centers. Strengths: smooth ride. | 12 (mainly fuel related) | Avoid completely |
| 2018 | PHEV / Fuel Cell | 8.0/10 | Minor infotainment slow to boot, some 12V battery drain reports; otherwise solid first-year PHEV. | 9 (mostly electronics) | 👍 Good but choose 2019+ if budget allows |
| 2019 | PHEV / Fuel Cell / Electric (BEV) | 8.8/10 | PHEV very robust; BEV version (89mi range) unsuitable for most. Software refinement improved, better HVAC logic. | 17 (concentrated on BEV range complaints) | 🥇 Best for PHEV, avoid BEV |
| 2020 | PHEV / Fuel Cell | 9.3/10 | Exceptional reliability; Honda Sensing standard, no significant mechanical flaws. Excellent battery chemistry. | 3 minor (all software-related) | ⭐ Highly Recommended |
| 2021 | PHEV / Fuel Cell (rare) | 9.6/10 | Final model year — peak refinement. Updated telematics, improved sound deadening, highest owner satisfaction. Fuel cell version still impractical. | 1 (no pattern) | 🏆 Best Year Ever (PHEV) |
⚡ Types Of Honda Clarity: Which One Suits You? (PHEV, FCEV, BEV)
47mi EV · 340mi gas · 110 MPGe
Best all-rounder
366mi range · Hydrogen refuel ~5min
Only for CA hydrogen network
89mi range · 25.5 kWh battery
Limited but cheap to run
Why the PHEV dominates: It gives you EV driving for daily commutes (zero gas) while completely eliminating range anxiety. The 1.5L Atkinson-cycle engine sips fuel (42 MPG) only when needed. Compared to the Clarity Fuel Cell, the PHEV has widespread refueling options and lower running costs. Compared to the BEV, the PHEV has almost triple the total range. For 99% of buyers, 2019-2021 Clarity PHEV is the smart choice.
✅ Advantages & ❌ Disadvantages Of Honda Clarity (Best vs Worst Years)
⭐ Advantages (Best Years: 2020-2021 PHEV)
- 🏆 Outstanding electric range — 47 miles, more than Prius Prime (25mi) and comparable to newer EVs.
- 💰 Low total ownership cost — $600/year fuel savings vs gas sedan.
- 🛡️ IIHS Top Safety Pick+ plus standard Honda Sensing (auto braking, lane keep).
- 🔇 Refined, quiet cabin — better NVH than most hybrids.
- 🚙 Spacious interior with premium materials (Touring trim).
- 🔋 Battery warranty 8yr/100k, excellent degradation track record.
⚠️ Disadvantages (Worst Years / General drawbacks)
- ⛔ 2017 Fuel Cell: hydrogen infrastructure = virtually undrivable outside CA hydrogen corridors.
- 🔋 2019 BEV: 89mi range is poor for modern EV standards (Chevy Bolt had 238mi).
- 📦 Trunk space slightly compromised (13.5 cu ft) due to battery placement.
- 🔄 Discontinued after 2021 — though parts are still widely available from Honda.
- 📱 Infotainment touch lag (2018/2019) but fixed in later updates.
- 🏎️ Not a performance car: 0-60 ~7.5 sec (PHEV) adequate but not thrilling.
🛡️ Is The Honda Clarity Safe? Crash Tests & Driver Assistance (All Years)
Yes — exceptionally safe. The Honda Clarity earned the 2020 IIHS Top Safety Pick+ award with “Good” ratings in all crash tests (small overlap front, side, roof strength). NHTSA gave it a 5-star overall rating (5 stars frontal, 5 stars side). Every Clarity from 2018 onward includes Honda Sensing®: Collision Mitigation Braking, Road Departure Mitigation, Adaptive Cruise Control, Lane Keeping Assist. Additionally, the Clarity features driver attention monitor and multi-angle rearview camera. Whether you buy a 2019 or 2021 PHEV, safety remains top-tier.
🛠️ How To Choose & Maintain A Honda Clarity For Maximum Lifespan
Buying checklist for best years: ✅ Look for 2020 or 2021 Plug-in Hybrid with under 60k miles. ✅ Request battery health report (dealership can run HV battery test). ✅ Check service history for regular oil changes (even if engine used rarely). ✅ Avoid 2019 BEV unless you only do short trips. ✅ For Fuel Cell: just don’t unless you live next to a hydrogen station and have deep pockets.
Maintenance tips: 1️⃣ Charge to 80% daily, 100% only before long trips. 2️⃣ Use 0W-20 synthetic oil change every 1-2 years or 10k miles. 3️⃣ Replace 12V battery every 4 years (prevents system glitches). 4️⃣ Cabin air filter every 15k miles. 5️⃣ Coolant for high-voltage system every 50k miles. Average annual maintenance cost = $380, less than many conventional midsize sedans.
💰 Ownership Costs, Depreciation & Resale Value By Year
Resale ~$9k – $12k
High depreciation
Resale $15k – $19k
Very stable
Resale $21k – $25k
Best value retention
Annual operating cost comparison: Clarity PHEV (electricity + occasional gas) ~$700/year vs Accord 1.5T ~$1,600/year. Plus, Clarity qualifies for used EV tax credit (up to $4,000 if bought from dealer and income limits apply).
