Specs side by side
What owners say
EV6
Overall
Predominantly positive sentiment, with owners frequently praising the vehicle's driving dynamics, fast charging capability, stylish design, and overall value as an electric vehicle. The consensus is that it is a joy to drive, with many stating they would not return to an internal combustion engine vehicle. However, significant concerns are raised regarding specific reliability issues, most notably the ICCU (Integrated Charging Control Unit) failure and 12V battery problems.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim. The GT-Line AWD is mentioned positively for its performance (0-60 mph/0-97 km/h in approximately 4.5 seconds).
Known issues
- ⚠ICCU (Integrated Charging Control Unit) failure: Can lead to the vehicle being disabled. A known recall issue, with a stated statistical failure rate of around 1% for affected vehicles. Many vehicles have had the remedy applied.
- ⚠12V auxiliary battery failure: Causes various electrical gremlins and can strand the vehicle. Often requires replacement, with some attributing issues to poor OEM battery quality. Frequency: very frequent.
- ⚠Significant cold-weather range reduction: Real-world range can drop from approximately 280 miles (451 km) in summer to 200-210 miles (322-338 km) or lower in winter, depending on climate and use of cabin heat.
Solterra
Overall
Mixed sentiment with a clear generational divide. Owner feedback for the 2023-2025 model years is predominantly negative, characterized by widespread criticism of its slow DC fast charging speeds, conservative real-world range (especially in cold weather), laggy and outdated infotainment system, and a general perception of being an uncompetitive "compliance car" or "2 generation old EV masquerading as a new car." Satisfaction is reported only when purchased at steep discounts or via very cheap lease deals. In contrast, the 2026 model year receives markedly more positive feedback, with owners reporting that Subaru/Toyota have addressed many core criticisms.
Best version to buy
2026 Model Year (any trim). There is a very strong, recurrent consensus that the 2026 model represents a significant improvement over earlier years, fixing major flaws like slow charging, lack of battery preconditioning, and outdated interior tech.
Known issues
- ⚠Slow DC Fast Charging (pre-2026 models): Very slow charging speeds compared to competitors, lack of battery preconditioning, major pain point for road trips. Frequency: very frequent.
- ⚠Conservative/Reduced Range in Cold Weather: Real-world range significantly drops in winter, with reports as low as 150 miles (241 km) from a full charge, causing anxiety. Frequency: very frequent.
- ⚠Outdated/Laggy Infotainment System: System is "a decade behind," prone to reboots while driving, poor native navigation requiring a paid subscription, slow response. Frequency: very frequent.
