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.
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.
