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).
XT5
Overall
Mixed sentiment with a clear generational divide. The vehicle is consistently praised for its comfortable ride, quiet interior, spacious cabin, and perceived value when purchased used at a significant discount from MSRP. Long-term owners express strong satisfaction with the vehicle's practicality and overall driving experience when properly maintained.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim. Commentary suggests higher trims (Platinum, Premium Luxury) are sought for their enhanced interior materials and feature content.
Known issues
- Sudden engine/electrical shutdown while driving: Vehicle loses all power, dashboard lights flash, may engage parking brake; often linked to battery/charging system faults but causes can be elusive. Primarily reported in 2017-2019 models.
- Outdated/unreliable infotainment system (CUE): Screen freezes, goes black while driving, unresponsive touch controls, Bluetooth/Apple CarPlay connectivity issues causing audio to only play from front speakers at low quality.
- Transmission problems (2017-2019 models): Shuddering, stuttering, rough shifts; noted to be largely resolved in 2020+ models. Frequency: recurrent.
