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 Y
Overall
Mixed sentiment with a clear evolution over time. Early community feedback from the 2020-2021 period highlighted significant excitement for the vehicle's technology, safety ratings, and practicality, including mentions of a power liftgate and 7-seat capability. However, this was immediately tempered by very frequent and severe criticism of poor initial build quality, including panel gaps and other defects on early delivery units.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Discussions indicate a clear hierarchy where higher "Premium" trims are perceived as offering significant improvements over the base "Standard" model.
Known issues
- ⚠Poor initial build quality: panel gaps, misalignments, and various defects on delivery, particularly noted on early production units (2020-2021). Frequency: very frequent.
- ⚠Uncomfortable ride quality: harsh, firm suspension criticized for providing a poor ride, often described as among the least comfortable in the segment. Frequency: very frequent.
- ⚠Excessive road and wind noise: noticeable at highway speeds, attributed to thin glass and insufficient sound deadening, especially on Standard trim with single-pane glass. Frequency: very frequent.
