Specs side by side
What owners say
e-tron
Overall
Sentiment is sharply divided, heavily dependent on the specific model and purchase context. For the e-tron SUV/Sportback (now Q8 e-tron), long-term owner reports are generally positive regarding its exceptional comfort, quiet ride, luxurious interior, and real-world reliability, especially for 2021+ models. However, this is contrasted by very frequent and severe criticism of its software, mobile app, and infotainment system, which are described as unreliable and poorly executed.
Best version to buy
For the e-tron SUV, the 2021 and newer models with the MIB3 infotainment upgrade are strongly recommended over 2019-2020 MIB2 units, which suffer from neglected software support. The 'Advanced' or 'Prestige' trims are noted for maximizing luxury features like massage/cooling seats and acoustic glass.
Known issues
- ⚠Unreliable mobile app and remote connectivity (e.g., climate control): frequent disconnections, commands fail to send or execute, system downtime. Frequency: very frequent.
- ⚠Buggy and slow infotainment software: system freezes, laggy response, requires reboots, older MIB2 systems are unsupported. Frequency: very frequent.
- ⚠Extreme depreciation: values can drop 60-70% over 5 years, making new purchases financially unfavorable. Frequency: very frequent.
Model X
Overall
Sentiment is mixed and heavily dependent on model year and generation. Long-term owner reports for high-mileage examples (e.g., 350,000 miles) highlight impressive battery durability with minimal degradation and low maintenance costs, fostering strong positive sentiment regarding powertrain longevity and efficiency. However, there is a very frequent and sharp criticism regarding build quality, reliability, and quality control across multiple model years, particularly for the S and X platforms compared to the Model 3/Y.
Best version to buy
Insufficient owner data available to declare a consensus "best version." Owner discussions indicate important generational divides: post-March 2018 vehicles with the MCU2 (Intel) infotainment are considered the minimum viable for features like Sentry Mode. The May 2019 "Raven" update is noted for improved suspension, motors, and range.
Known issues
- ⚠Poor build quality and reliability: very frequent mentions of squeaks, rattles, odd noises, and various quality control defects affecting the S and X platforms. Frequency: very frequent.
- ⚠High repair costs and complexity: cited as inevitable for older models, with few independent specialists and expensive Tesla service parts, particularly concerning for "Legacy" models. Frequency: recurrent.
- ⚠Falcon wing door problems: mentioned as a potential failure point to inspect thoroughly before purchase. Frequency: isolated.
