This review is on my moms 2007 Rdx, bought new in 2006 on my recommendation, which I have driven on and off over the past 10 years, including 10 hour road tips, mountain ski trips in the snow, etc. She now has around 100k miles on it and has not had a single trip for unscheduled maintenance in that time. Acceleration is quick for an suv and the handling is sporty and precise. Ride is quite firm, you will feel every bump in the road, but the chassis feels solid. The sh-awd handles great in the snow and it was a great vehicle to take on ski trips. Passenger and cargo space is reasonable and visibility is good. Stereo is good and materials are nice but not overly luxurious. Only negatives are requiring premium fuel for the turbo engine, and averaging only around 18mpg (90% stop and go city driving.). Road trips to the mountains I would be lucky to eek out 23-24 mpg. Buy this for its Honda reliability and being fun to drive, not for its gas mileage.
Check engine light came on at 92000 miles. The dealer diagnosed a failing turbo, around $4500 to fix. I don't expect a premium car to fail at this mileage. Also the ride is fairly harsh as is road noise. Fun to drive though.
The 2007 model drives and handles like a 5 series BMW. The seats hold you securely on spirited curves. Later models were softened up and "family car" dumbed down. If you want fun, get a 2007. If you want a polite quality family car, get a later model.
I've had no maintenance or repair problems with my RDX. All maintenance at Acura dealership. No repairs beyond scheduled service. Drive 25K/yr in Northern and Central Valley California. Most miles on I-5 at 70 mph. Also into Sierra foothills in light snow. Acceleration is great entering highway and passing on 2 lane roads.
Only negative comments - suspension is very tight. Wonderful for cornering but bothersome on poor roadways at highway speed. I still prefer it to my wife's 2007 MDX. Premium fuel required but knew this when I bought it. Interior is great except center console armrest is thin vinyl that began to wear and tear after 4 years. Mentioned to dealer and they acknowledged that other owners had same complaint. Overall great car, hoping to get 50K more on it waiting for Tesla Model 3.
