Specs side by side
What owners say
Q8 e-tron
Overall
Mixed sentiment with a clear divide between appreciation for the vehicle's core luxury attributes and significant frustration with reliability and technology. The vehicle is very frequently praised for its exceptional interior build quality, quiet and refined ride comfort, smooth handling, and overall feeling of traditional luxury. Many owners describe it as one of the quietest and most comfortable vehicles they have owned, with a high-quality interior that feels like a proper luxury car.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim. Feedback indicates the higher-trim Prestige models are appreciated for their feature content, but no specific trim level is singled out as being significantly more reliable or recommended over others.
Known issues
- Software glitches and MMI failures: Virtual cockpit resets, screen freezes, non-responsive touchscreens, system lag, false error messages (tire pressure, child lock), persistent bugs requiring multiple dealer software updates.
- Major electrical system failures: Complete vehicle shutdowns rendering car undriveable, battery replacement required, indeterminate electrical faults causing extended shop visits (30+ days). Frequency: recurrent.
- 12V battery drain issues: Caused by faulty components like stuck seat switches, leading to a dead vehicle. Warranty disputes common over fault attribution. Frequency: recurrent.
RZ
Overall
Mixed sentiment with a clear divide between satisfaction with the vehicle's core attributes and significant disappointment with its electric powertrain capabilities. Owners who acquired the vehicle at substantial discounts (e.g., $20,000 off MSRP) and use it strictly as a local commuter report high satisfaction, praising its smooth and comfortable ride, quiet cabin, high-quality build and finish, and refined interior. However, there is a very frequent and dominant criticism of the vehicle's limited EPA-rated range (196-220 miles / 315-354 km), which is considered a major competitive weakness.
Best version to buy
Luxury trim over Premium trim. The Luxury trim is noted for including a sunshade for the glass roof, which is a significant comfort feature missing on the Premium trim.
Known issues
- Limited EPA-rated range: Very frequent criticism, with EPA ratings of 196 miles (315 km) for Luxury trim and 220 miles (354 km) for Premium trim considered insufficient for the segment.
- Slow charging speed: Cited as a major drawback compared to competitors, impacting usability for longer trips. Frequency: very frequent.
- Unreliable voice command system ("Hey Lexus"): Frequently fails to understand or execute commands, leading owners to default to smartphone integration. Frequency: recurrent.
