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).
Q5
Overall
Mixed sentiment with a clear dichotomy. The vehicle is consistently praised for its superior driving dynamics, handling, and refinement compared to mainstream and some luxury competitors. Owners frequently describe it as "fun to drive," "super quiet and smooth," and possessing a solid, tank-like build quality.
Best version to buy
The 3.0T supercharged V6 engine (found in pre-2017 Q5 models and in the SQ5) is very frequently recommended over the 2.0T four-cylinder for its power, refinement, and perceived reliability. For newer generations, the plug-in hybrid Q5 e is suggested as a high-feature, powerful, and efficient alternative to the performance-oriented SQ5.
Known issues
- High maintenance and repair costs: very frequent mentions of routine services costing $1,400-$3,000, with out-of-warranty repairs described as exceptionally expensive. Frequency: very frequent.
- Electronic/Infotainment glitches: includes CarPlay/Bluetooth connectivity failures, random system reboots, unresponsive screens, and parasitic battery drain causing "Low Battery" warnings in new models (e.g., 2025).
- Sunroof leaks: noted as a design flaw in some generations (e.g., Q3/Q5), requiring extensive disassembly and often recurring. Frequency: recurrent.
