Specs side by side
What owners say
RDX
Overall
Owners of the second-generation RDX (roughly 2013-2018) are overwhelmingly positive, repeatedly describing the V6 as smooth, potent, and long-lived, with many reporting 150,000 to nearly 300,000 miles on basic maintenance. The third-generation RDX (2019 and later) draws a split verdict: owners praise the turbocharged engine's mid-range punch, handling, and available ELS audio, but a substantial group reports infotainment problems, interior rattles, brake noise, and occasional turbo or head gasket failures. A recurring theme is that the older naturally aspirated V6 is viewed as the more trouble-free long-term choice, while the newer turbo four is seen as more fun but less proven.
Best version to buy
Insufficient owner data available to declare a single consensus. The strongest signal favors the second-generation V6 models, with 2013-2015 and 2017-2018 examples drawing the most praise for reliability and longevity, and the 2016-2018 facelift years noted for holding up well past 100,000 miles.
Known issues
- Infotainment system freezing, slow response, and night/day mode glitches: Frequency: very frequent (concentrated in 2019-2020 model years). Panoramic sunroof rattles, popping, or leaking: Frequency: recurrent (2019-2022 model years).
CX-7
Overall
Owner sentiment is mixed and heavily dependent on the specific powertrain. The vehicle is praised for its attractive styling, comfortable and well-appointed interior, and capable driving dynamics, particularly on open roads. However, significant and very frequent criticism is directed at the reliability and long-term ownership costs of the turbocharged gasoline engine (2.3L), which is widely reported to be problematic and expensive to repair.
Best version to buy
The consensus strongly favors avoiding the turbocharged 2.3L gasoline engine. Among available options, the naturally aspirated 2.5L gasoline engine is recommended for better reliability, though it is noted to be underpowered.
Known issues
- Problematic turbocharged 2.3L gasoline engine: widely reported as unreliable, with high repair costs and long-term failure concerns. Frequency: very frequent.
- Poor fuel economy: noted for both gasoline and diesel engines, especially in city or heavy traffic conditions. Diesel variant specifically criticized for high consumption on short trips. Frequency: very frequent.
- Transmission sensitivity: gearboxes described as sensitive and expensive to repair; careful driving and regular fluid changes advised. Frequency: recurrent.
