What owners say
Clarity
Overall
Mixed sentiment with a strong positive bias among long-term owners who appreciate the vehicle's core value proposition. The Plug-In Hybrid (PHEV) variant is consistently praised for its exceptional all-electric range (frequently cited as best-in-class at the time), refined and quiet cabin, comfortable ride quality attributed to a sophisticated multi-link rear suspension, and high-quality interior materials that exceed typical Honda expectations, offering an Acura-like feel. Owners report high satisfaction with the ability to conduct daily commutes entirely on electricity while having a gasoline engine for longer trips.
Best version to buy
The Plug-In Hybrid (PHEV) variant is overwhelmingly the version discussed and recommended by owners. The Fuel Cell (FCV) and Battery Electric (BEV) variants are mentioned only in the context of the model's history and discontinuation, with no substantive owner feedback provided in the data.
Known issues
- Air Conditioning System Failures: Recurrent and costly failures of both the evaporator and condenser components, described as a "ticking timebomb" in used vehicles. Repairs reported in the $2,500 USD range. Frequency: very frequent.
- Traction Battery Failure: Complete failure of the main hybrid battery pack preventing the vehicle from starting or running, requiring replacement. One report of failure at approximately 65,000 miles. Frequency: recurrent.
- Infotainment Software Bugs: Issues with Android Auto voice navigation cutting out when music is playing; auto day/night mode for the display not functioning; system requiring resets. Frequency: recurrent.
IONIQ
Overall
Sentiment varies significantly by model line. For the original IONIQ (Hybrid/PHEV/Electric), feedback is consistently positive, praising it as an underappreciated, efficient, and practical commuter car with low maintenance costs and good value. For the newer E-GMP platform vehicles (IONIQ 5, 6, 5N), sentiment is highly polarized but leans positive among owners.
Best version to buy
For the IONIQ 5, the Limited (or Ultimate/Premium in some markets) trim is frequently mentioned as the preferred version for its premium features like a head-up display (HUD), ventilated seats, a retractable sunshade, and a quieter cabin. The SEL trim is noted as a good value compromise.
Known issues
- **ICCU (Integrated Charging Control Unit) failure**: Can cause complete vehicle shutdown, triggers dashboard warnings, requires replacement.
- **12V auxiliary battery failures**: Multiple replacements reported within early ownership period on IONIQ 5. Frequency: recurrent.
- **Software quality**: Described as "just ok," clunky, or buggy compared to Tesla; slow infotainment response noted. Frequency: recurrent.
