Specs side by side
What owners say
IONIQ 5
Overall
Sentiment is sharply divided, creating a high-risk, high-reward ownership profile. On the positive side, the vehicle is very frequently praised for its unique and head-turning retro-futuristic design, spacious and comfortable interior, smooth and quiet ride quality, rapid DC charging capability (800V architecture), and useful Vehicle-to-Load (V2L) feature. Many owners report high satisfaction, describing it as one of the best cars they've owned, with excellent driving dynamics and practicality.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim. Commentary indicates the Limited (or Ultimate) trim is appreciated for its higher feature content, including a physical button for seat profiles.
Known issues
- ⚠ICCU (Integrated Charging Control Unit) failure: causes complete vehicle shutdown, long repair delays, subject of government investigation and potential class-action lawsuits. Frequency: very frequent.
- ⚠Software bugs and electronic glitches: slow user profile loading, cruise control and driver aids disabled by rain/snow, system freezes, unreliable wireless CarPlay/Android Auto. Frequency: very frequent.
- ⚠12V battery failures: causes warning messages and complete no-start conditions, requiring booster packs or replacement. Frequency: recurrent.
Leaf
Overall
Sentiment is sharply divided by generation and use case. For the first-generation models (notably 2011-2013), feedback is overwhelmingly negative due to severe battery degradation, loss of remote access services, and poor cold-weather performance, leading to significant owner frustration and financial loss. Second-generation models (2018 onward) receive a more mixed to positive assessment, particularly as low-cost, reliable urban runabouts.
Best version to buy
For second-generation models (2018+), the high-spec Tekna (or SL trim in some markets) is recommended for its heated seats and steering wheel, leather, LED headlights, and better equipment, which enhance comfort, especially in winter. For first-generation models, no specific version is recommended; owners advise avoiding 2011-2013 models entirely.
Known issues
- ⚠Severe battery degradation and cold-weather performance loss (Gen1: 2011-2013): Rapid loss of battery capacity, "lizard" battery issues, catastrophic range loss in cold weather, leading to unusable vehicles. Frequency: very frequent.
- ⚠Passive battery thermal management: Causes rapid state-of-charge (SOC) drop during highway driving in cold weather, battery isolation faults, swollen cells, and long-term health concerns. Cited as a fundamental design flaw.
- ⚠Outdated CHAdeMO fast-charging standard: Limited and declining public charger availability, making road trips difficult and reducing long-term utility. Frequency: very frequent.
