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.
JX
Overall
Mixed to negative sentiment overall, with significant concerns overshadowing positive attributes. The vehicle is acknowledged for its practicality as a 7-seat SUV, comfortable ride, good highway cruising manners, and respectable fuel economy for its class, with reports of up to 26 MPG on road trips. However, owner feedback is dominated by severe and recurrent reliability issues, primarily centered on the JATCO CVT transmission, which is described as problematic and prone to early failure.
Best version to buy
Insufficient owner data available. No specific trim or model year within the JX generation (2013-2015) is singled out as superior.
Known issues
- CVT transmission failures: very frequent reports of complete failure, slipping, jerking, and long-term reliability concerns. Described as prone to wearing out faster than traditional automatics. Frequency: very frequent.
- Charging system and electrical faults: recurrent and severe issues involving alternators failing and outputting excessive voltage (16.1+ volts), which subsequently damages the ECU and other electronics.
- Major rust issues: severe corrosion of the rear subframe and suspension control arm bushings, requiring complete replacement of the subframe assembly: a repair costing $4,000-$10,000. Frequency: recurrent.
