What owners say
RDX
Overall
Mixed to positive sentiment for first-generation model, regarded as pioneering turbocharged compact luxury SUV offering engaging driving dynamics and strong performance but compromised by turbocharger reliability concerns and aging platform limitations. Praised for powerful 2.3L turbocharged engine producing 240 hp delivering spirited acceleration (0-60 mph approximately 6.5-7.0 seconds), SH-AWD system providing excellent handling and winter capability, spacious interior with premium materials, and Honda build quality when properly maintained. However, widespread criticism centers on turbocharger failures requiring expensive replacements ($2,500-$4,000) typically 100,000-150,000 miles, dated technology even when new (no Bluetooth early years, primitive infotainment), poor fuel economy (18-20 MPG combined with premium fuel requirement), and suspension noise (strut mount bearings, control arm bushings deteriorate early).
