Specs side by side
What owners say
Q7
Overall
Mixed sentiment with a clear generational divide. Long-term owners of the 2015-2018 generation (particularly with the 3.0L supercharged V6 or TDI engines) report high satisfaction, praising solid reliability, excellent performance and handling, and a high-quality, comfortable interior. This generation is frequently described as a "great car" and "infallible" with proper maintenance.
Best version to buy
For the 2015-2018 generation, the 3.0L supercharged V6 gasoline engine is highly recommended for its balance of power and reported reliability. The 3.0L TDI is also praised for its torque and efficiency.
Known issues
- High maintenance and repair costs: very frequent. Excessive oil consumption in later models (e.g., 1 quart every 1,500 miles considered "normal" by manufacturer): recurrent.
Cayenne
Overall
Sentiment is sharply divided by generation and ownership context. For newer models (approximately 2019+), feedback is mixed to negative, with very frequent and severe criticism directed at the latest infotainment and control systems. Owners report a frustrating, laggy, and bug-ridden user interface, poor software stability, and the removal of physical controls for critical functions like climate and drive modes, which is seen as a significant regression.
Best version to buy
For older used models (circa 2011-2018), the base V6 model is frequently cited as the most reliable and cost-effective choice to own, with the V8 'S' model also recommended for those seeking more power. There is a strong, recurrent warning to avoid models equipped with air suspension due to high repair costs.
Known issues
- **Newer Models (2019+):** Infotainment & Control System Failures: Severe software bugs, input lag, unresponsive touch screens, basic functions buried in deep menus, slow response to steering wheel controls. Frequency: very frequent.
- Removal of Physical Controls: Critical functions (climate, ride height, exhaust mode) moved to touch surfaces or infotainment, degrading usability and safety. Frequency: very frequent.
- **Older/Used Models (Pre-2019):** High Cost of Ownership: Extremely expensive routine maintenance, brakes, tires, and repairs. Dealership oil changes cited at ~$500 USD, brake jobs over $3,000 USD. Frequency: very frequent.
