Specs side by side
What owners say
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.
Model 3
Overall
Mixed sentiment with a clear generational divide. Long-term owners of earlier models (pre-2024 "Highland") report significant mechanical reliability issues, particularly with suspension components, leading to high out-of-warranty repair costs and diminished resale value. These owners often express frustration with build quality, citing water leaks and inconsistent service experiences.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Discussions indicate a trade-off: the Long Range AWD model is noted for extra mileage and all-weather capability, while the Performance model is desired for its faster acceleration and exterior styling.
Known issues
- ⚠Front suspension/control arm failures: Worn out control arms, loose steering racks, described as "almost inevitable" and a primary cause of high failure rates in mandatory vehicle inspections. Frequency: very frequent.
- ⚠Build quality and water leaks: Trunk and frunk leaks that can recur after paid repairs. Frequency: recurrent.
- ⚠High out-of-warranty repair costs: Significant expenses for components like the onboard charger, amplifier, and suspension parts after warranty expiration. Frequency: recurrent.
