Based on the previous generation Honda CR-V, among compact luxury SUVs, the RDX is benign and unassuming. While it lacks the agility and top notch interior quality of its peers, it's functional, reliable and relatively fuel efficient. One high point is its smooth, powerful V6, which, combined with its six-speed automatic transmission, manages a very respectable 22 mpg overall.

Reliability

We expect the 2022 RDX will have about average reliability when compared to the average new car. This prediction is based on data from 2019, 2020 and 2021 models. Select the used car model year to see reported issues with those similar past models.

Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey for over 300,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2021 vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system. NA indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

In-dash navigation system (GPS)

"the navigation system shuts off along with the radio and then reboots itself and comes back on by itself. I took the car to the Acura dealer and they were able to replicate the problem. The dealer contacted Acura Canada and they told the dealer to replace the navigation system under warranty. i have presently been waiting six weeks for the part . I personally called Acura Canada but I am still waiting, I am not real pleased with this kind of service."

Anonymous, ON (2018 Acura RDX None 3.5-L V6)

Anonymous, ON (2018 Acura RDX None 3.5-L V6)

Anonymous, MI (2018 Acura RDX None 3.5-L V6)

"Acura infotainment is set up to work primarily with Android phones. The best they could do with Apple was a Siri derivative which is an abysmal failure 50% of the time. This has been ongoing and is a major reason this will be my last Acura after 17 years of Acura products 1-TL, 3-RDXs"

"It does not clearly play certain FM radio stations that work fine in other vehicles."

There is no way to verbally cancel a route once vehicle thinks it has correct info - even though it has used a number as the name of street.
