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.
bZ4X
Overall
Mixed to negative sentiment overall, with a clear generational divide. The initial 2022-2025 model years are widely criticized as a rushed, uncompetitive compliance product, with very frequent complaints about poor real-world range, extremely slow DC fast charging, and a lack of expected features like battery preconditioning and a glovebox. Owner feedback describes it as a "half baked" vehicle that feels 5 years behind competitors, with Toyota perceived as not genuinely committed to its success.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim. However, there is a strong, recurrent recommendation for the AWD version over FWD, particularly for the 2026 model year, due to its superior traction in snow ("a god damn tank in the snow") and more powerful drivetrain.
Known issues
- ⚠Poor real-world range: significantly below EPA estimates, especially in cold weather or with climate control use, with reports as low as 170 miles from a full charge. Frequency: very frequent.
- ⚠Extremely slow DC fast charging: peak rates of only 100-150 kW, with charging sessions from low state of charge taking up to 60-90 minutes to reach 80%; lack of battery preconditioning in early models severely hampers cold-weather charging…
- ⚠Missing common features: no glovebox, no trunk light, poor cabin storage, no frunk, and (in early models) no battery preconditioning or built-in route planning for chargers. Frequency: very frequent.
